I am new to iOS and was wondering which is the best to learn. I have read some of the answers here and SO, but some people say use Storyboards will others say learn XIBs first. Is there any real benefit to learning XIBs? Are XIBs easier to understand and will help with storyboards?

Storyboards vs. the old XIB way

In a custom xib file, what&#39;s the difference between the two following setting methods shown in the images below?

What&#39;s the difference between custom class and file&#39;s owner setting in xib file?

I want to change below code with storyboard with Xcode 4.2.

    UIViewController * example     = [[ExampleViewController alloc] initWithNibName:@&quot;ExampleViewController&quot; bundle:nil];

Now ExampleViewController.xib file exist.
but I want to make it with storyboard.
please help me.
(I&#39;m not good at English. Sorry)

How do I change &quot;initwithNibName&quot; in storyboard?

The question is simple: How do you load custom `UITableViewCell` from Xib files? Doing so allows you to use Interface Builder to design your cells. The answer apparently is not simple due to memory managment issues. [This thread][1] mentions the issue and suggests a solution, but is pre NDA-release and lacks code. Here&#39;s a [long thread][2] that discusses the issue without providing a definitive answer. 

Here&#39;s some code I&#39;ve used:

    static NSString *CellIdentifier = @&quot;MyCellIdentifier&quot;;
    
    MyCell *cell = (MyCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
    	NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil];
    	cell = (MyCell *)[nib objectAtIndex:0];
    }

To use this code, create MyCell.m/.h, a new subclass of `UITableViewCell` and add `IBOutlets` for the components you want. Then create a new &quot;Empty XIB&quot; file. Open the Xib file in IB, add a `UITableViewCell` object, set its identifier to &quot;MyCellIdentifier&quot;, and set its class to MyCell and add your components. Finally, connect the `IBOutlets` to the components. Note that we did not set the File&#39;s Owner in IB.

Other methods advocate setting the File&#39;s Owner and warn of memory leaks if the Xib is not loaded via an additional factory class. I tested the above under Instruments/Leaks and saw no memory leaks. 

So what&#39;s the canonical way to load cells from Xibs? Do we set File&#39;s Owner? Do we need a factory? If so, what&#39;s the code for the factory look like? If there are multiple solutions, let&#39;s clarify the pros and cons of each of them...

How do you load custom UITableViewCells from Xib files?

This seems like such a basic task, but I&#39;m stumped.

How, in Xcode, do you execute a textual search though (the XML contents of) all the .xib files in a project?

For example, all of our .xib files contain this string on the second line: `com.apple.InterfaceBuilder3.CocoaTouch.XIB`. So I&#39;d think that searching all project files for that string would return all .xib files, but Xcode insists &quot;0 occurrences&quot;. I&#39;ve double checked that the Project Find Options look correct.

I must be missing something obvious. (Or Xcode is somehow hard-coded to skip .xib files.)

I&#39;m trying to find all the .xib files that reference a particular class (and a text search seems like the most direct way).

Thanks!



Text search though all .xib files in Xcode?

Jonathan suggest here: https://stackoverflow.com/questions/4980296/xcode-includes-xib-files-that-have-been-deleted/4980405#4980405 that cleaning all targets and empty the caches will fix the problem with Xcode including deleted .xib files but I cannot find a way to empty the cache in Xcode 4.

How to Empty Caches and Clean All Targets Xcode 4 and later

My problem is that I was looking for way to use both **storyboard** and **xib**. But I can&#39;t find proper way to load and show storyboard programmatically. Project was started developing with xib, and now it&#39;s very hard to nest all xib files in storyboard. So I was looking a way to do it in code, like with `alloc, init, push` for viewControllers. In my case I have only one controller in storyboard: `UITableViewController`, which has static cells with some content I want to show. If anyone knows proper way to work both with xib and storyboard without huge refactoring, I will appreciate for any help.

How can I load storyboard programmatically from class?

I added a new nib file to my project, and tried to load it.

However, when I click on the toolbar icon that is supposed to take me to the view that I created, I get an `NSInternalInconsistencyException` with the message:

&gt; Terminating app due to uncaught exception
&gt; &#39;NSInternalInconsistencyException&#39;, reason: &#39;-[UIViewController
&gt; _loadViewFromNibNamed:bundle:] loaded the &quot;...&quot; nib but the view outlet was not set.&#39;

So I opened up my nib file, and I see for the view that there are no referencing outlets set.  However, I try to click and drag the circle for &quot;new referencing outlet&quot; to File&#39;s Owner, but it won&#39;t let me...what do I need to do to get my view to display?


Loaded nib but the &#39;view&#39; outlet was not set

Here is my Objective-C code which I&#39;m using to load a nib for my customised `UIView`:

Could not insert new outlet connection

I want to use a view throughout multiple viewcontrollers in a storyboard. Thus, I thought about designing the view in an external xib so changes are reflected in every viewcontroller. But how can one load a view from a external xib in a storyboard and is it even possible? If thats not the case, what other alternatives are availble to suit the situation abouve?

Load view from an external xib file in storyboard

Storyboards are rather a royal pain from a git workflow perspective when multiple people are collaborating on them. For example, the XML in the .storyboard file has its starting `&lt;document&gt;` tag&#39;s `toolsVersion` and `systemVersion` attributes altered by whatever configuration the most recent file manipulator happens to be running. Synchronizing everybody&#39;s Xcode versions precisely seems to help with `toolsVersion`, but `systemVersion` changes no matter what, depending on the specific Mac and/or OS X version the developer is running.

This is idiotic, but mostly harmless. What worries us, though, is that at other times some other changes are automatically made to the storyboard just by opening them after a `git pull`. That is to say, Alice makes changes to a storyboard, commits and pushes them to the repository. Bob then pulls Alice&#39;s changes and opens up the storyboard to make further changes. The moment he opens the storyboard, the file icon immediately changes to a modified-but-unsaved state, and a `git status` shows that any number of weird changes have occurred. All this without Bob having changed anything or saved the file himself.

The most common automated change we&#39;re seeing is the disappearance or reappearance of the entire `&lt;classes&gt;` tag hierachy near the end of a storyboard file. We haven&#39;t figured out what is causing this. We may have several localized versions of a storyboard in various .lproj directories, and when opening them inside Interface Builder, the class hierarchy may spontaneously be removed from some and added into others, or left alone in some. This causes a lot of noise in `git diff`, but it doesn&#39;t actually break any functionality. We will often selectively add the actual changes we made into git&#39;s index, commit those, and then just discard the spontaneous, nonsensical `&lt;classes&gt;` changes. This is to keep commits small and nice, as they should be. Eventually, though, it just becomes too much to bother with since Xcode keeps re-doing the changes, and someone just ragecommits them along with some other stuff... which is fine until someone else&#39;s Xcode decides to want to change them back for no apparent reason. (Our commit history has a lot of swearing over this.)

Is anyone else seeing this behaviour? Is this an Xcode bug or a configuration issue on one or more of our developer Macs? We&#39;ve seen some similar behaviour when collaborating with XIB files, but storyboards seem more susceptible to this.

Xcode changes unmodified storyboard and XIB files

I have been searching everywhere and nothing so far has worked for me.

Basically I want to have a .xib file called rootView.xib and inside it I want to have a UIView  (lets call it containerView) that takes up only half of the screen (so there would be the regular view and a new view). Then I want a different .xib file called firstView.xib and load it inside of containerView. So I can have a bunch of stuff on firstView.xib and a bunch of different stuff in rootView.xib and load my firstView.xib inside of containerView in rootView.xib but since it only takes up half of the screen you would still see the stuff on rootView.xib

How to load a xib file in a UIView

I am aware this question has been asked before but the answers are contradicting and I am confused, so please don&#39;t flame me.

I want to have a reusable `UIView` subclass throughout my app. I want to describe the interface using a nib file.

Now let&#39;s say it&#39;s a loading indicator view with an activity indicator in it. I would like on some event to instantiate this view and animate in to a view controller&#39;s view. I could describe the view&#39;s interface no problem programmatically, creating the elements programmatically and setting their frame inside an init method etc.

How can I do this using a nib though? Maintaining the size given in interface builder without having to set a frame.

I&#39;ve managed to do it like this, but I&#39;m sure it is wrong (it&#39;s just a view with a picker in it):

     - (id)initWithDataSource:(NSDictionary *)dataSource {
            self = [super init];
            if (self){
                self = [[[NSBundle mainBundle] loadNibNamed:[NSString stringWithFormat:@&quot;%@&quot;, [self class]] owner:self options:nil] objectAtIndex:0];
                self.pickerViewData = dataSource;
                [self configurePickerView];
            }
            return self;
        }

But I&#39;m overwriting self, and when I instantiate it:

    FSASelectView *selectView = [[FSASelectView alloc] initWithDataSource:selectViewDictionary];
        selectView.delegate = self;
        
        selectView.frame = CGRectMake(0, self.view.bottom + 50, [FSASelectView width], [FSASelectView height]);

I have to manually set the frame rather than have it picked up from IB.

EDIT: I want to create this custom view in a view controller, and have access to control the view&#39;s elements. I don&#39;t want a new view controller.

Thanks

**EDIT: I Don&#39;t know if this is best practice, I&#39;m sure it&#39;s not, but this is how I did it:**

    FSASelectView *selectView = [[[NSBundle mainBundle] loadNibNamed:[NSString stringWithFormat:@&quot;%@&quot;,[FSASelectView class]] owner:self options:nil] objectAtIndex:0];
        selectView.delegate = self;
        [selectView configurePickerViewWithData:ds];
        selectView.frame = CGRectMake(0, self.view.bottom + 50, selectView.width, selectView.height);
        selectView.alpha = 0.9;
        [self.view addSubview:selectView];
        [UIView animateWithDuration: 0.25 delay: 0 options:UIViewAnimationOptionAllowUserInteraction |UIViewAnimationOptionCurveEaseInOut animations:^{
                                selectView.frame = CGRectMake(0, self.view.bottom - selectView.height, selectView.width, selectView.height);
                                selectView.alpha = 1;
                            } completion:^(BOOL finished) {
                            }];

**Correct practice still wanted**

Should this have been done using a view controller and init with nib name? Should I have set the nib in some UIView initialisation method in the code? Or is what I have done ok?

Correct way to load a Nib for a UIView subclass

In complex screens (View Controllers) I used to separate the whole thing in smaller pieces (I call them widgets). These widgets consist basically of a `MyWidget.h` and a `MyWidget.m` file as well as a `MyWidget.xib` file, where the root element is a `UIView` and the MyWidget class is the File Owner of the UIView. In the init of this widget I do a `loadNibNamed`.

In my View Controller I then do a `[[MyWidget alloc] init]`, which I add to View&#39;s Controller main view as a sub view. This, so far, works perfectly.

I&#39;m now wondering, how to do the same with storyboard, because I cannot really start to drag in a `UIView` somewhere, I always have to start with an `UIViewController`, which I don&#39;t want to.

If there is no possible way doing this with a Storyboard, can I simply do it the old way, by using the Storyboard for my main screens and segues, and use a separate .xib file to define custom views?

Custom views with Storyboard

I typically like to create and design my uiviews in interface builder. Sometimes I need to create a single view in a xib that can be reused in multiple view controllers in a storyboard.

How do you do it?  I saw one video tutorial on it, but the screen was too small.  Also, other than changing the view size, are there any other major changes I would have to make to my iphone apps to convert to iPad?

How to set Hex color code in xib in iOS

I just created one new cordova ios project via CLI, and i opened that project in Xcode 7.1 and while running on simulator am getting some error on mainViewController.xib, if we clicked on that error its showing xib file and on top of that showing one warning message  &quot;An internal error occurred. Editing functionality may be limited&quot; . So am unable to run this project.


I don&#39;t know whether this is due to Xcode bug or cordova bug or any other settings issue in my Xcode.

What are the **main differences** between using Storyboards and xib files.

  Specifically,
 what are the **advantages or disadvantages** of using a Storyboard?

  Unfortunately, despite doing quite a bit of research, all I&#39;ve been able to find on Storyboards are simple tutorials that show you how to set up a Storyboard, instead of concrete information explaining what they are.

What are the benefits of using Storyboards instead of xib files in iOS programming?

I&#39;ve created a view in a xib (with an activity indicator, a progress view and a label).
Then I&#39;ve created .h/.m files:

    #import &lt;UIKit/UIKit.h&gt;

    @interface MyCustomView : UIView {
        IBOutlet UIActivityIndicatorView *actIndicator;
        IBOutlet UIProgressView *progressBar;
        IBOutlet UILabel *statusMsg;
    }

    @end

    #import &quot;MyCustomView.h&quot;
      
    @implementation MyCustomView    

    - (id)initWithFrame:(CGRect)frame {
        if ((self = [super initWithFrame:frame])) {
            // Initialization code
        }
        return self;
    }

    - (void)dealloc {
        [super dealloc];
    }

    @end


**In IB, I set the file&#39;s owner and view identity to MyCustomView and connect the IBOutlet to the File&#39;s owner**

In MyViewController.m, I&#39;ve:

    - (void)viewDidLoad {

        [super viewDidLoad];   

        UIView *subView = [[MyCustomView alloc] initWithFrame:myTableView.frame];
        [subView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]];

        [myTableView addSubview:subView];
        [subView release];
    }

When I run the app, the view is added, but I can&#39;t see the label, the progress bar and the activity indicator. 

What am I doing wrong?

Adding a custom subview (created in a xib) to a view controller&#39;s view - What am I doing wrong

I had a `MyViewController.swift` and a `MyViewController.xib` presenting the layout of MyViewController.

I tried different methods to load this view controller including:

 

    //1
    let myVC = UINib(nibName: &quot;MyViewController&quot;, bundle:
           nil).instantiateWithOwner(nil, options: nil)[0] as? MyViewController

    //2
    let myVC = NSBundle.mainBundle().loadNibNamed(&quot;MyViewController&quot;, owner: self, options: nil)[0] as? MyViewController

    //3
    let myVC = MyViewController(nibName: &quot;MyViewController&quot;, bundle: nil)

The third one is the only successful initialisation, but the previous two are causing error:

&gt; Terminating app due to uncaught exception &#39;NSUnknownKeyException&#39;,
&gt; 
&gt; reason: &#39;[&lt;MyApp.XXX 0x7fe8f151b4c0&gt; setValue:forUndefinedKey:]: this
&gt; class is not key value coding-compliant for the key XXX.

What&#39;s wrong with those loading methods?

Loading ViewController from xib file

in objective c it can be done in init method by


    -(id)init{
        self = [[[NSBundle mainBundle] loadNibNamed:@&quot;ViewBtnWishList&quot; owner:0 options:nil]     objectAtIndex:0];
    return self;
    }

but when i do this in swift

    init(frame: CGRect) {
        self = NSBundle.mainBundle().loadNibNamed(&quot;ViewDetailMenu&quot;, owner: 0, options: nil)[0] as? UIView
    }

cannot assign to self in a method error is shown.
now my approach is to create a view, and add the view loaded from nib to it.
anyone have a better idea?

Assign xib to the UIView in Swift

When I navigate to one of my xib files, Xcode marks the file as touched. Undo and revert have no effect.  Saving seems to do no harm, but the glitch causes me frequent additional git work.  

Has anyone else seen this or have an idea about something in my MainWindow.xib that would cause it?  

Edit in 2019 - still happening!
