Question

DismissViewController UIButton causes my app to crash when testing on iPod touch. Otherwise, it is working fine on iPhone. iPod version is 4.2.1.

The message I am getting is:

dismissViewControllerAnimated:completion:]: unrecognized selector sent to instance 0x153720′

-(void)dismissViewDidFinish:(UIViewController *)viewController 
{

[self dismissViewControllerAnimated:YES completion:nil];

}    

This is the modalviewcontroller h file:

@class Info;

@protocol InfoDelegate 

-(void)dismissViewDidFinish:(UIViewController *)viewController;

@end

Answer 1

Where is the method “dismissViewController” defined? It’s not a framework method. If you’ve used code from an example, be sure you define the method where you intend to. It is not a method on UIViewController.

If you are trying to dismiss a modal view controller, from the modal view controller, the way to do it is:

[self dismissModalViewControllerAnimated:YES];
