title: getting signal SIGABRT in first IOS project, Xcode 4
body: <p>I am trying to create my first test app in IOs and everything I do gets me that error. I am using xcode 4.4.</p>
  
  <p>The app is very simple. It has a button, and When I press it, a label and an imageview must appear.</p>
  
  <p>My whole code is this:</p>
  
  <pre><code>ViewController.h
  
  
  //
  //  ViewController.h
  //  helloWorld_04
  //
  //
  
  #import &lt;UIKit/UIKit.h&gt;
  
  @interface ViewController : UIViewController{
  
      IBOutlet UILabel *label;
      IBOutlet UIImageView *Kant;
  }
  @property (nonatomic, retain) IBOutlet UILabel *label;
  @property (nonatomic, retain) IBOutlet UIImageView *Kant;
  - (IBAction)buttonGuess:(id)sender;
  
  @end
  </code></pre>
  
  <p>and my implementation file:</p>
  
  <pre><code>#import "ViewController.h"
  
  @interface ViewController ()
  
  @end
  
  @implementation ViewController
  @synthesize label,Kant;
  
  - (void)viewDidLoad
  {
      [super viewDidLoad];
      // Do any additional setup after loading the view, typically from a nib.
  }
  
  
  
  - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
  {
      return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
  }
  
  - (void)dealloc {
      [label release];
      [Kant release];
      [super dealloc];
  }
  - (IBAction)buttonGuess:(id)sender {
      label.text=@"Hello World i am back!";
      UIImage *imageSource=[UIImage imageNamed:@"kantStair.png"];
      Kant.image=imageSource;
  }
  @end
  </code></pre>
  
  <p>My error log is this:</p>
  
  <pre><code>2012-08-23 13:38:50.030 helloWorld_04[537:c07] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[&lt;ViewController 0x6a5e1f0&gt; setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key image.'

  terminate called throwing an exception(lldb) 
  </code></pre>
  
  <p>and it gets me that signal in that line:</p>
  
  <pre><code>//
  //  main.m
  //  helloWorld_04
  //
  
  //
  
  #import &lt;UIKit/UIKit.h&gt;
  
  #import "AppDelegate.h"
  
  int main(int argc, char *argv[])
  {
      @autoreleasepool {
          return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
      }
  }
  </code></pre>
  
  <p>I have read several answers here but not found sollution to my problem, that why I made it a new question. I thought that it may be a problem with the connection so what I did on my own was to "darg and drop" my label and my image to "file's owner" but still getting the error.</p>
