Local declaration of ‘i’ hides instance variable.

where do you put this exit to ensure it is executed regardless of how user crashes out of screen?

I am trying to call this within a IBAction. How do I call it correctly?

- (IBAction)addAction:(id)sender
{
// The add button was clicked, handle it here
NSLog(@”UIButton was clicked”);

[self textFieldCheck];
}
