Universal app crashes on iPad simulator at each alternate time

My app crashes on iPad simulator in alternate builds, crash then run then crash, etc.

objc[1116]: Class Protocol is implemented in both /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/lib/libobjc.A.dylib and /Users/NGA24iMAC3/Library/Application Support/iPhone Simulator/4.2/Applications/C0FFA7D7-7684-4854-B641-62BD11CFD226/Innovations.app/Innovations. One of the two will be used. Which one is undefined.

  1. Open our iPad xib in Interface Builder
  2. Click on File's ownner
  3. In the Inspector, go to the fourth tab (Identity)
  4. Write as class identity the name of the class that is acting as view controller for that xib.
  5. Ready to go!

@Ishu i think that something is wrong with your connections in IB.I know you checked your IB but can you make your .xib file once again.

I also faced same problem in my Universal app .

I did something like this that solved my problem - 

- (id)initWithNibName:(NSString *)n bundle:(NSBundle *)b
{
    return [self init];
}


- (id)init
{



    BOOL iPad = NO;
#ifdef UI_USER_INTERFACE_IDIOM
    iPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#endif


    if (iPad) 
    {
        // iPad specific code here
        NSLog(@"Device is iPad");
        [super initWithNibName:@"ContactUsViewController~ipad" bundle:nil];

    } else 
    {
        // iPhone/iPod specific code here
        NSLog(@"Device is iPhone");
        [super initWithNibName:@"ContactUsViewController" bundle:nil];

    }

    return self;
}

when you are adding/pushing viewController just call its init method and then push viewcontroller.

I suggest cleaning your project. Command + Shift + K

Next, open your XIB file and verify that the view outlet of the "File's Owner" is connected to your view. Of not connect and it and save.

Rebuild your project.
