Answer 1

Instead of create IBOutlet, you have to make IBAction to directly get click event

check out this image...

This Is .m file where i create IBAction directly

and if you want to give click event programatically then follow @Nicolas Buquet answer

Answer 2

Add this to your code:

[OkBtn addTarget:self action:@selector(okButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

and add this method to your class:

- (void)okButtonTapped:(UIButton *)sender {
NSLog(@"Ok button was tapped: dismiss the view controller.");
}

The okButtonTapped: method will be called when you tap iside the button and remove your finger (the 'up" part).
