iphone - How to make round corner button which supports all device in iOS

Question

In my iPhone app i have profile pic button which should be round corner always.Right now if i will give corner radius some value ,button is not round cornered in iPhone 6plus.So is there any specific general way to make this work ? Thanks in advance...

Answer 1

If size of the button (width, height) are same in all screen sizes then setting cornerRadius once should work, if its different in different screen sizes then do something like this, add button as property and then override viewDidLayoutSubviews method of view controller class

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    self.button.layer.cornerRadius = self.button.bounds.size.height / 2;
}
