touchesBegan question for iPhone/iPad App

I have an App and in my touchesBegan, I move an image to another view. After I move the image I replace the original image with the same image with an alpha of .5.

However, the the user can still touch the 'dimmed' image and move it. I do not want them to be able to select any of the 'dimmed' images. I thought maybe I could cancel the touches begin when the user touches the first time, but I am not sure how to cancel it.

UPDATE: As per the suggestions posted, I have done this in my touchesBegan:

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

{ UITouch * touch = [touches anyObject]; if (self.alpha >= 1) { // DO STUFF } else self.userInteractionEnabled = NO; }

However, that does not appear to solve the problem as I can still drag the image and drop it.

Any other ideas would be appreciated!! 开发者_运维技巧

you can disable user interaction on any view using

view.userInteractionEnabled = NO;

Try this...

self.userInteractionEnabled = NO;
