In your error view (command+4, by default, or the 4th tab in the left hand view) you can click the little arrow next to the warning, and it should tell you 

&gt;Method definition for &#39;blah&#39; not found

I&#39;ve found that sometimes the Log Navigator is the only way to show the actual problem - in at least one case, the error view didn&#39;t help me. To see the Log Navigator, you can use View &gt; Navigators &gt; Show Log Navigator (or ⌘7 by default).

In the `val`[docs][1] written  this description:

&gt; .val() Returns: String, Number, Array

I tried to get a `Number`, but it seems to return `string` only, Is there something that I&#39;m doing wrong?

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-js --&gt;

    $(&#39;#gdoron&#39;).val(&#39;1&#39;);

    alert($(&#39;#gdoron&#39;).val() === &#39;1&#39;); // true 
    alert(typeof $(&#39;#gdoron&#39;).val());  // string.

    $(&#39;#gdoron&#39;).val(1);

    alert($(&#39;#gdoron&#39;).val() === 1);  // false
    alert(typeof $(&#39;#gdoron&#39;).val()); // string (not &quot;number&quot;!)

&lt;!-- language: lang-html --&gt;

    &lt;script src=&quot;https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js&quot;&gt;&lt;/script&gt;
    &lt;input type=&quot;text&quot; id=&quot;gdoron&quot; /&gt;

&lt;!-- end snippet --&gt;

My question is: **how can `val()` return number as the docs says?** The question is not about how can I parse the string.

How can val() return Number?

I have an automated build process that I&#39;d like to extend so I can build the libraries I am distributing via NuGet.  Currently, running nuget.exe to create the packages is a manual operation.

**What is the best way to setup VS 2010 so that my NuGet package (*.nupkg) file is the end result of a &quot;Release&quot; build?**

Keep in mind that I have other files (content and tools) for some of the packages. And, in most cases, I have multiple projects merged into a single NuGet package to support .NET 4, Silveright and Phone 7.

*(I should clarify that the existing &quot;automated&quot; process is a simple batch-file runner that builds a solution using the command line.)*

**UPDATE**

I want to refresh this discussion because the issue has not been resolved.  While the link @pravin supplied is helpful, it doesn&#39;t address the fact that I have multiple projects in a single package as well as other contents like PowerShell scripts, configuration and source code transformations, etc.

The best example I can use is an assembly that has both a .NET 4 and Silverlight 5 version. These are distributed in the same package.  I cannot use a post-build event to create the package because the package is dependent upon TWO projects.

Sometimes I forget to implement a method in one of my classes, and Xcode displays a &quot;Incomplete implementation&quot; warning.

Is there any way in Xcode to see **which** method implementation is missing?

Block syntax in Objective C (and indeed C, I presume) is notoriously incongruous. Passing blocks as arguments looks different than declaring blocks as ivars, which looks different than `typedef`ing blocks.

Is there a comprehensive list of block-declaration syntax that I could keep on hand for quick reference?

I have an NSMutable dictionary that contains file IDs and their filename+extension in the simple form of fileone.doc or filetwo.pdf. I need to determine what type of file it is to correctly display a related icon in my UITableView. Here is what I have done so far.

    NSString *docInfo = [NSString stringWithFormat:@&quot;%d&quot;, indexPath.row]; //Determine what cell we are formatting
    NSString *fileType = [contentFiles objectForKey:docInfo]; //Store the file name in a string

I wrote two regex to determine what type of file I&#39;m looking at, but they never return a positive result. I haven&#39;t used regex in iOS programming before, so I&#39;m not entirely sure if I&#39;m doing it right, but I basically copied the code from the Class Description page. 

        NSError *error = NULL;
    NSRegularExpression *regexPDF = [NSRegularExpression regularExpressionWithPattern:@&quot;/^.*\\.pdf$/&quot; options:NSRegularExpressionCaseInsensitive error:&amp;error];
    NSRegularExpression *regexDOC = [NSRegularExpression regularExpressionWithPattern:@&quot;/^.*\\.(doc|docx)$/&quot; options:NSRegularExpressionCaseInsensitive error:&amp;error];
        NSUInteger numMatch = [regexPDF numberOfMatchesInString:fileType options:0 range:NSMakeRange(0, [fileType length])];
        NSLog(@&quot;How many matches were found? %@&quot;, numMatch);

My questions would be, is there an easier way to do this? If not, are my regex incorrect? And finally if I have to use this, is it costly in run time? I don&#39;t know what the average amount of files a user will have will be.

Thank you.

I&#39;m trying to use storyboards in an app I&#39;m working on. In the app there are **Lists** and **Users** and each contains a collection of the other (members of a list, lists owned by a user). So, accordingly, I have `ListCell` and `UserCell` classes. The goal is to have those be re-usable throughout the app (ie, in any of my tableview controllers). 

That&#39;s where I&#39;m running into a problem. 

**How do I create a custom tableview cell in the storyboard that can be re-used in any view controller?** 

Here are the specific things I&#39;ve tried so far.

 - In Controller #1, added a prototype cell, set the class to my `UITableViewCell` subclass, set the reuse id, added the labels and wired them to the class&#39;s outlets. In Controller #2, added an empty prototype cell, set it to the same class and reuse id as before. When it runs, the labels never appear when the cells are shown in Controller #2. Works fine in Controller #1.

 - Designed each cell type in a different NIB and wired up to the appropriate cell class. In storyboard, added an empty prototype cell and set its class and reuse id to refer to my cell class. In controllers&#39; `viewDidLoad` methods, registered those NIB files for the reuse id. When shown, cells in both controllers were empty like the prototype.

 - Kept prototypes in both controllers empty and set class and reuse id to my cell class. Constructed the cells&#39; UI entirely in code. Cells work perfectly in all controllers.


In the second case I suspect that the prototype is always overriding the NIB and if I killed the prototype cells, registering my NIB for the reuse id would work. But then I wouldn&#39;t be able to setup segues from the cells to other frames, which is really the whole point of using storyboards.

At the end of the day, I want two things: wire up tableview based flows in the storyboard and define cell layouts visually rather than in code. I can&#39;t see how to get both of those so far.

In a storyboard, how do I make a custom cell for use with multiple controllers?

I have one `NSDictionary` and it loads up `UITableView`. If a user scrolls more and more, I call API and pull new data. This data is again in the form of an `NSDictionary`. Is it possible to add the new `NSDictionary` to the existing one?

I am developing the front facing camera app in iPad2 by using the `UIImagePickerController`.

When I capture the image it&#39;s shows as flipped from left to right.

How do I correct this?

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
        {
            UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
            imgPkr.delegate = self;
            imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
            imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;
            
    
            UIImageView *anImageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@&quot;select%d.png&quot;,val]]];
            anImageView.frame = CGRectMake(0, 0, anImageView.image.size.width, anImageView.image.size.height);
            imgPkr.cameraOverlayView = anImageView;
            [theApp.TabViewControllerObject presentModalViewController:imgPkr animated:YES];
            [imgPkr release];
        }

I am currently making an app that will have multiple timers, which are basically all the same. 

I want to create a custom class that uses all of the code for the timers as well as the layout/animations, so I can have 5 identical timers that operate independently of each other. 

I created the layout using IB (xcode 4.2) and all the code for the timers is currently just in the viewcontroller class.

I am having difficulty wrapping my brain around how to encapsulate everything into a custom class and then add it to the viewcontroller, any help would be much appreciated.

How do I create a custom iOS view class and instantiate multiple copies of it (in IB)?

I have been using a shell script as part of my Xcode build process to increment the build number within the *plist* file, however it&#39;s making Xcode 4.2.1 crash frequently (with an error about the target not belonging to a project; I&#39;m guessing the changing of the *plist* file is confusing Xcode in some way).

The shell script did this so that the build number is only incremented by `agvtool` when a file is newer than the *plist* file (so just building didn&#39;t increment the value):

    if [ -n \&quot;`find ProjDir -newer ProjDir/Project-Info.plist`\&quot; ]; then agvtool -noscm next-version -all; else echo \&quot;Version not incremented\&quot;; fi

Is there a way to increment the build number (in the *plist* file, or anywhere else) that doesn&#39;t break Xcode?

**FINAL EDIT**:  I now do this kind of stuff using a python script which I have just made public on [github](https://github.com/trojanfoe/xcodedevtools).  It&#39;s not well documented but shouldn&#39;t be difficult to work out.  As a bonus this repo also contains a useful script to automatically bundle 3rd party library into an app bundle. 

Better way of incrementing build number?

I&#39;m writing C++ code on a mac. Why do I get this error when compiling?:

&gt; Undefined symbols for architecture i386:   &quot;Log::theString&quot;,
&gt; referenced from:
&gt;       Log::method(std::string) in libTest.a(Log.o) ld: symbol(s) not found for architecture i386 clang: error: linker command failed with
&gt; exit code 1 (use -v to see invocation)

Not sure if my code is wrong or I have to add additional flags to Xcode. My current XCode configurations are the default ones for a &#39;static library&#39; project.

My code:  

Log.h------------

    #include &lt;iostream&gt;
    #include &lt;string&gt;
    
    using namespace std;
    
    class Log{
    public:
        static void method(string arg);
    private:
        static string theString ;
    };

Log.cpp ----

    #include &quot;Log.h&quot;
    #include &lt;ostream&gt;
    
    void Log::method(string arg){
        theString = &quot;hola&quot;;
        cout   &lt;&lt; theString &lt;&lt; endl; 
    }

I&#39;m calling the &#39;method&#39; from a test code, in this way:
&#39;Log::method(&quot;asd&quot;):&#39;

thanks for your help.
