Animating frame change of UIView is not smooth, results in a bouncy effect

Question

I am trying to animate the frame change of an UIView where both the origin and the size changes. The animation doesn't look smooth and has got a bouncy effect. I am using the following code to do that

[UIView
    animateWithDuration:0.5
    animations:^{
        self.view.frame = newFrame;
    }];

It seems that the size first changes very fast and then the origin changes with the specified duration of the animation which finally results in a bouncy effect. How do I make this look smooth?

Answer 1

You could try to change the animation curve, maybe try the linear one.

dispatch_async(dispatch_get_main_queue(), ^{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationCurve:UIViewAnimationCurveLinear];
    self.view.frame = newFrame;
    [UIView commitAnimations];
});

Answer 2

On animating the frame change of each of the subviews individually did the magic. Now it animates very smoothly. Thanks.
