Question

I have a gesture recognizer attached to a view and I’d like to be able to unit test which method it calls when the tap occurs. My gesture recognizer is created like so…

- (void)setupMyView {
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myViewTapped)];
    self.myView.userInteractionEnabled = YES;
    [self.myView addGestureRecognizer:tap];
}

How can I access the name of the selector (myViewTapped) that is called when the tap occurs?

Thanks so much in advance for your wisdom!

Unfortunately, neither UIGestureRecognizer nor UITapGestureRecognizer exposes this information.

UIControl, for example, exposes allTargets and allControlEvents, which is basically what you are looking for, but it is unfortunately unavailable for UIGestureRecognizer

As a result, I do not believe what you want is possible without using private methods.
