Question

Here is my code ,

-(IBAction)casser{
     oeuf1.contentMode       =   UIViewContentModeScaleAspectFit;
    [UIView animateWithDuration:1.0 animations:^{ 
         CGRect newRect      =   oeuf1.frame;
         newRect.size.width *=   5;
         oeuf1.frame         =   newRect;
         [oeuf1 release];
    }];
}

“oeuf1” is a UIButton
I want to multiply its width by five when I touch the button, but when I do that the button moves to the right and its width doesn’t change. How can I solve this?

Tested code 100% works

connect each method with specified

-(IBAction)expand{//touch down


    NSLog(@"expand");

    [UIView transitionWithView:but duration:0.0 options:UIViewAnimationOptionTransitionNone animations:^(void) {


        CGRect newRect = but.frame;

        CGPoint ce= but.center;
        newRect.size.width *= 5;

        but.frame = newRect;    

        but.center=ce;



    } completion:^(BOOL finished) {



    }];


}

 -(IBAction)shrink{//touch up inside
    NSLog(@"shrink");


    [UIView transitionWithView:but duration:0.0 options:UIViewAnimationOptionTransitionNone animations:^(void) {


        CGRect newRect = but.frame;

        CGPoint ce= but.center;
        newRect.size.width /= 5;

        but.frame = newRect;    

        but.center=ce;



    } completion:^(BOOL finished) {



    }];


}
