For iOS 8, 9, and 10 the height is **49 points**, both on iPad and iPhone and both in portrait and landscape. It used to be 56 points on iOS 7.

For iOS 11, things get a bit more complicated:

In **portrait** and **regular landscape**, the height is still **49 points**.
In **compact landscape**, the height is now **32 points**.

On iPhone X, the height is **83 points** in portrait and **53 points** in landscape.

iOS 9 and iOS 10 still uses 49 points for the Tab Bar (and 64 points for a navigation bar)
Thanks for the self Q/A, was actually helpful to conform what I had on storyboard.

I would recommend just calculating it using `TabBar.Height - UIApplication.SharedApplication.KeyWindow.SafeAreaInsets.Bottom`. Check for system version &gt;= 11 first.

| iPhone | portrait | landscape |
| -------- | -------------- |  -------------- |
| 5s/SE/6/6s/7/8(iOS10)    | 49           | 49 |
| 5s/SE/6/6s/7/8(iOS11)   | 49            | 32 |
| X/XS/XR   | 83(49+34)            | 53(32+21)|
| XS Max   | 83(49+34)            | 70(49+21) |


you can get by this method:
`self.tabBarController?.tabBar.frame.size.height`

I want to show a picture into imageView like the image contact (in a circle) But when I try to show this, the imageView rescale his size and this doesn&#39;t show correctly in a circle.

     image.layer.borderWidth=1.0
     image.layer.masksToBounds = false
     image.layer.borderColor = UIColor.whiteColor().CGColor
     image.layer.cornerRadius = image.frame.size.height/2
     image.clipsToBounds = true

I want to show like this: 
![enter image description here][1]

But I get this:
![enter image description here][2]

How can do the image resize to UIImageView size to show as a circle?

Thanks!

I am writing an application where `Activity A` launches `Activity B` using 

    startActivityForResult(intent, -101);

but when called, it responded back with following error log:

    E/AndroidRuntime( 1708): java.lang.IllegalArgumentException: Can only use lower 16 bits for requestCode
    E/AndroidRuntime( 1708): 	at android.support.v4.app.FragmentActivity.startActivityForResult(FragmentActivity.java:837)

Probably it could be **-101** but I am not sure. Does any one have any idea on this?

I&#39;m looking for a way to disable the &quot;pinch to zoom&quot; magnification gesture on the iOS implementation of WKWebView. There is a magnification BOOL property available for OS X but it doesn&#39;t seem to be available on iOS.

WKWebView.h

    #if !TARGET_OS_IPHONE
    /* @abstract A Boolean value indicating whether magnify gestures will
     change the web view&#39;s magnification.
     @discussion It is possible to set the magnification property even if
     allowsMagnification is set to NO.
     The default value is NO.
     */
    @property (nonatomic) BOOL allowsMagnification;

I&#39;ve, also, tried look at the WKWebView&#39;s gesture recognizers but that seems to be turning up an empty array. I&#39;m assuming the actual recognizers are bured deeper in the component&#39;s structure (fairly complex, by the looks of it) and would rather not go digging for them if at all possible.

I know of possible hacks that could potentially disable the gesture from firing (selectively passing gestures to the WebView, add child view to capture pinch gesture, etc) but I&#39;ve always found those introduce lag into the event and want to keep the implementation as clean/hack free as possible.

Disable magnification gesture in WKWebView

I am working on some javascript UI, and using a lot of touch events like &#39;touchend&#39; for improved response on touch devices. However, there are some logical issues which are bugging me ...

I have seen that many developers mingle &#39;touchend&#39; and &#39;click&#39; in the same event. In many cases it will not hurt, but essentially the function would fire twice on touch devices:

    button.on(&#39;click touchend&#39;, function(event) {
      // this fires twice on touch devices
    });

It has been suggested that one could detect touch capability, and set the event appropriately for example:

    var myEvent = (&#39;ontouchstart&#39; in document.documentElement) ? &#39;touchend&#39; : &#39;click&#39;;
    button.on(myEvent, function(event) {
      // this fires only once regardless of device
    });

The problem with the above, is that it will break on devices that support both touch and mouse. If the user is currently using mouse on a dual-input device, the &#39;click&#39; will not fire because only &#39;touchend&#39; is assigned to the button.

Another solution is to detect the device (e.g. &quot;iOS&quot;) and assign an event based on that:
https://stackoverflow.com/questions/8503453/click-event-called-twice-on-touchend-in-ipad.
Of course, the solution in the link above is only for iOS (not Android or other devices), and seems more like a &quot;hack&quot; to solve something quite elementary.

Another solution would be to detect mouse-motion, and combine it with touch-capability to figure out if the user is on mouse or touch. Problem of course being that the user might not be moving the mouse from when you want to detect it ...

The most reliable solution I can think of, is to use a simple [debounce][1] function to simply make sure the function only triggers once within a short interval (for example 100ms):

    button.on(&#39;click touchend&#39;, $.debounce(100, function(event) {
      // this fires only once on all devices
    }));

Am I missing something, or does anyone have any better suggestions?

*Edit:* I found this link after my post, which suggests a similar solution as the above:
https://stackoverflow.com/questions/7018919/how-to-bind-touchstart-and-click-events-but-not-respond-to-both

When dismissing various view controllers using `UIModalPresentationCustom`, the screen turns black after the view controller is dismissed, as if all the view controllers had been removed from the view hierarchy.

The transitioning delegate is set properly, the animationControllerForPresentedController is asked for and passed correctly, and the transition is completed once the animation is over. 

This exact code works perfectly when compiled with the iOS 7 SDK, but is broken when compiled with iOS 8b5 

iOS 8 - Screen blank after dismissing view controller with custom presentation

I&#39;m using Swift for programing with iOS and I&#39;m using this code to move the `UITextField`, but it does not work. I call the function `keyboardWillShow` correctly, but the textfield doesn&#39;t move. I&#39;m using autolayout.

    override func viewDidLoad() {
        super.viewDidLoad()
        NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector(&quot;keyboardWillShow:&quot;), name:UIKeyboardWillShowNotification, object: nil);
        NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector(&quot;keyboardWillHide:&quot;), name:UIKeyboardWillHideNotification, object: nil);
    }

    deinit {
        NSNotificationCenter.defaultCenter().removeObserver(self);
    }

    func keyboardWillShow(notification: NSNotification) {
        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
            //let contentInsets = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0)
            
            var frame = self.ChatField.frame
            frame.origin.y = frame.origin.y - keyboardSize.height + 167
            self.chatField.frame = frame
            println(&quot;asdasd&quot;)

Move textfield when keyboard appears swift

I was using this code to determine what is the size of the keyboard :

    - (void)keyboardWillChange:(NSNotification *)notification {
        NSDictionary* keyboardInfo = [notification userInfo];
        NSValue* keyboardFrameBegin = [keyboardInfo valueForKey:UIKeyboardFrameBeginUserInfoKey];
        CGRect keyboardFrameBeginRect = [keyboardFrameBegin CGRectValue];
    
    }

I&#39;m running this in the simulator.

The problem is since iOS 8 this will not give the correct value, if the keyboard suggestions is up or if I push them down I get different (not correct) values.

How can I get the exact size of the keyboard including the keyboard suggestions?

Open AppStore through button

Say I want a bundled image to take up all available screen width in an iPhone app - for example a banner. I&#39;d create `my_banner.png` with width `320px`, `my_banner@2x.png` with width `640px` and `my_banner@3x.png` for *iPhone 6 plus* with width `1242px`. But the resolution of *iPhone 6* is `750&#215;1334` pixels. Still it shares the `@2x` suffix with iPhone 4 and 5 that have `640px` width. 

What&#39;s the **recommended way** or a **good way** to specify an image file that has been optimised for the `750px` width of *iPhone 6*? Seems like it cannot be done in an `asset catalog`? Should it be done programatically? Is there some other suffix that can be used for *iPhone 6*?

How to load URL in UIWebView in Swift?

I am working on a swift app for iPhone. There is a modal view in my application that I want only to be in portrait view.

My question is, how do I programmatically force the phone to not allow rotation? In other words, I am looking for code that will not allow a modal view to be displayed in landscape mode (turning on portrait rotation lock).

This is just for 1 modal view, so I can&#39;t turn off rotation for the entire app, otherwise I would just disable rotation altogether.

I found code in my research [here][1]
But it is in objective C, in case that helps. Thanks!

I have an app, that works fine under iOS 7, but when built for iOS 8 the unwind segues are not working.

I created a new project and added a modal (navigationcontroller with tableviewcontroller)and tried to use an unwind modal. Unfortunately it doesn&#39;t work either. The methods that are being unwind to, are in the desination view controller. The unwind segue is created through the storyboard (a Navigationbar button in the tableviewcontroller) When I tap the button, nothing happens. There is no log output and the modal does not disappear. It also only seems to affect modal segues. push/popover are unwound normally.

Has anyone had a similar problem and has an Idea how I could solve it?

Change tab bar item selected color in a storyboard

I am currently adding images to each one of my tab bar items. One image I like has a size that is much bigger then the area of the bar item. When I set the image of the bar item in the storyboard and run the emulator... the bar button with that image covers the entire screen.

Now I thought there was some automatic way of allowing the images to resize for each bar button. This is sadly not the case. Is there a way when the tab bar loads that I can resize the images within each tab bar?

Here is my tab bar:

The following image shows the program being run and the &quot;NEWS&quot; item selected:

![enter image description here][2]

It is clear the bar tint color is working fine as I want !

But the tintColor only affects the image and not the text.

Also, when the an item is selected (as seen above, news) the item color goes blue! How do I prevent this from happening? I want it to stay white.

Why is the text changing to a white color when selected but not when it is unselected?

I basically want the item color and text color to be white all the time.

How do I achieve this? Thanks for any help.

Does it require swift code for each individual item?

Changing tab bar item image and text color iOS

I have a root view controller which isn’t set as the custom class for any of my view controllers on my storyboard. Instead, all of my view controllers are subclassing this class like so.

    // RootViewController
    class RootViewController: UIViewController, UITabBarDelegate { 
    
        // This is not getting executed on any of the view controllers
        func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {
            print(&quot;ddd&quot;)
        }
    }

    // Subclassing it 
    class TopStoriesViewController: RootViewController {

    }


But I seem to be struggling with doing something when a tabbaritem is pressed on the view controller which is subclassing the rootviewcontroller, i.e, the message is not being printed.

So, the new beta SDK of iOS released last night has &quot;App Transport Security&quot; which encourages developers to use https instead of http. In principle, this is a great idea, and I already use https in our staging/production environments. However, I don&#39;t have https set up in my local development environment, when the iOS app is connecting to a web service I&#39;m running on my laptop.

From a bit of playing around this morning, it appears that the URL loading system will, even if you hand it an http URL, decide to use https instead. Does anyone know how to disable this behaviour -- even just for particular URLs?
