UILabel Background Color Leaks to Border

Question

I\'m creating a UILabel to which I set the background color and corner radius with the following code:

self.scoreLabel.backgroundColor = [UIColor DISRed];// cust

Well, a lot of answers...

I found the problem persists, as long as the UIViews background color is used and not the background color of the UIViews 'layer'. In addition, of course, masking needs to be enabled.

For a UICollectionViewCell subclass the code is:

- (void)prepare
{
    self.contentView.layer.backgroundColor = UIColor.redColor.CGColor;
    self.contentView.layer.cornerRadius = 25.0;
    self.contentView.layer.borderColor = UIColor.blackColor.CGColor;
    self.contentView.layer.borderWidth = 1.0;
    //Enable to optimize image views: self.contentView.layer.shouldRasterize = YES;
    //Enable to optimize image views: self.contentView.layer.rasterizationScale = UIScreen.mainScreen.scale;
    self.contentView.layer.masksToBounds = YES;
    self.contentView.clipsToBounds = YES;
}

To make the setting of the background color more comfortable and less error prone, some could add this:

/*
 setBackgroundColor:

 */
- (void)setBackgroundColor:(UIColor *)p_BackgroundColor
{
    super.backgroundColor = nil;
    self.contentView.layer.backgroundColor = p_BackgroundColor.CGColor;

    self.contentView.layer.masksToBounds = YES;
    self.contentView.clipsToBounds = YES;
}
