Question

I am trying to get my animation move in more than one generated path. I got my codes down but I still don’t get what is wrong with it.

Here is where I place my image in the view

UIImageView *faceAni = [[UIImageView alloc] initWithFrame:CGRectMake(200, 100, 50.0, 50.0)];
        faceAni.animationImages = faces;
        faceAni.animationDuration = 10;
        faceAni.animationRepeatCount = 0;
        [faceAni startAnimating];
        [self addSubview:faceAni];

And here is where I try to get the animation to move in a triangular path coordinates.

[UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:1];


        [UIView animateWithDuration:4 
                              delay:0 
                            options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse  
                         animations:^{faceAni.transform = CGAffineTransformMakeTranslation(0, 200);} 
                         completion:^(BOOL finished) {

            [UIView animateWithDuration:4 
                                  delay:0 
                                options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse  
                             animations:^{faceAni.transform = CGAffineTransformTranslate(faceAni.transform, -100, 0);} 
                             completion:^(BOOL finished) {

                [UIView animateWithDuration:4 
                                      delay:0 
                                    options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse 
                                 animations:^{faceAni.transform = CGAffineTransformTranslate(faceAni.transform, 300, 0);} 
                                 completion:NULL];

            }];

        }];

I still don’t get what is wrong with my codes.

Thanks in advance!

It might help if you describe the behaviour that you’re seeing. As a guess, though, you probably don’t want the UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse flags you’re passing to each animation.
