Question

I have used this previously in my app, and having looked over everything I cannot find the difference, but for some reason when I run:

-(void)moveSelectorToDisplayPosition:(id)sender{

    int givenTag = [sender tag];
    UIImageView *tempImageView = [displayedSelections objectAtIndex:givenTag];



    [UIView beginAnimations:@"" context:NULL];
    [UIView setAnimationDuration:.3];
    tempImageView.frame = CGRectOffset(tempImageView.frame, 30 - tempImageView.frame.origin.x,  240 - tempImageView.frame.origin.y);
    [UIView setAnimationDidStopSelector:@selector(loadInTextForSelectedTool:)];
    [UIView commitAnimations]; 
}

loadInTextForSelectedTool does not get called and I cannot figure out why. No errors or anything.

This is the method I’m trying to run, could anyone let me know if they see anything amiss or maybe something I might have forgotten? I tried also setting the [UIView setAnimationDelegate:tempImageView]; but no luck :(.

-(void)loadInTextForSelectedTool:(id)sender;

Thanks.

You need to set the delegate to the controller that implements loadInTextForSelectedTool:

[UIView setAnimationDelegate:self];

Also, according to the documentation, the selector should have the following form:

- (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context

And finally, Apple discourages the use of this animation method in iOS 4.0 or later:

Use of this method is discouraged in iOS 4.0 and later. You should use
the block-based animation methods to specify your animations instead.
