iphone - UIView animate frame of ImageView -


i'm trying add animation uiimageview when button tapped. when button tapped want imageview move right @ same time increasing in size. have tried code, imageview aren't animation correct.

- (ibaction)ba:(id)sender {     [uiview beginanimations:nil context:null];     [uiview setanimationcurve:uiviewanimationcurvelinear];     [uiview setanimationduration:0.5];     cgrect frame = imageview.frame;     frame.origin.x = frame.origin.x + 30;     frame.size.hight = frame.size.hight + 20;     frame.size.width = frame.size.width + 20;     imageview.frame = frame;     [uiview commitanimations]; }

this code makes imageview move little right, again. wierd behavior, should animate both size , origin @ same time?

the problem you've got autolayout turned on. autolayout, cannot change frame of something, because layout comes along , changes again.

either turn autolayout off, or else animate changing constraints of view instead of frame.
