UITouch not working for UIImageView

[lamfan]

How can a touchesBegan method working for UIImageView?

 

inside touchesBegan

 

UITouch *touch = [[event allTouches] anyObject];

if([touch view] == imageView){

NSLog(@"touch imageView");

}

 

the imageView is a UIImageView, UITouch can't work when I touch the imageView.

 

Please Help!

Instead of the touchesBegan method, use the touchesMoved method. I think that should work.

I had try it and that's not work.

 

I think UITouch view method is only working with UIView instant.

 

Is there any other way to detect a UIImageView instant with UITouch method?

Watch this tutorial: Touches and UIImageViews. It covers how to use touches to move around an image.

yes I'm using the same tutorial, everything working fine be just

 

if([touch view] == UIImageView) <-- this one not working!

 

is there anything wrong or different version of xcode?

Try:

 

if([touch view] isTypeOfClass:UIImageView])

Why don't you just do this:

 

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

UITouch *touch = [touches anyObject];

if([touch view] == imageView){

NSLog(@"touch imageView");

}

}

I think you are mistaking the event with the set of touches

Find out the solution

 

New image view objects are configured to disregard user events by default. If you want to handle events in a custom subclass of UIImageView, you must explicitly change the value of the userInteractionEnabled property to YES after initializing the object.

I was gonna say something about that, but I just couldn't remember the method used to enable it :/
