提前致谢...

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...

推荐答案

如果按钮的大小（宽度，高度）在所有屏幕中都相同大小然后设置 cornerRadius 一旦应该工作，如果它在不同的屏幕尺寸不同然后做这样的事情，添加按钮作为属性，然后覆盖 viewDidLayoutSubviews 查看控制器类的方法

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;
}
