Unrecognized selector sent to instance

Question

Anyone know why I am getting this error?

Terminating app due to uncaught exception \'NSInvalidArgumentException\', reason: \'-[CustomRaisedTabViewController          


        

Answer 1

action: @selector(cancel:) 

For the action selector which takes parameter! cancel: that means which will take another parameter.

change your method to

-(IBAction)cancel:(id)sender{
// Do wat you want
}

or

-(IBAction)cancel:(UIButton *)btnSender{
/// Do what you want
}

Answer 2

you have to modify the cancel method signature in

-(IBAction)cancel:(id)sender
 { 
   [self.parentViewController dismissModalViewControllerAnimated:YES]; 
 }

when you added the action to your cancelButton (during initialization) you specified the "cancel:" selector, this means that it will be called a method having one parameter (the sender button)

Answer 3

Because the cancel: method is not cancel which is what you've defined.

Change your cancel action to look like this:

- (IBAction)cancel:(id)sender {
    ...
}
