Setting mask layer on UITableViewCell's subview overrides Auto Layout constraints

Question

I have a UITableViewCell with multiple subviews. One of the subviews is a UILabel and the cell\'s height is dynamically sized based on the amount of te

I finally got it. I'm not sure if this is the correct place to put this or if it might cause performance problems, but so far it works perfectly:

- (void)drawRect:(CGRect)rect
{
  [super drawRect:rect];

  UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.mySubview.bounds
                                               byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight | UIRectCornerBottomLeft | UIRectCornerBottomRight)
                                                     cornerRadii:CGSizeMake(10, 10)];

  CAShapeLayer *maskLayer = [CAShapeLayer layer];
  maskLayer.frame = self.mySubview.bounds;
  maskLayer.path = maskPath.CGPath;
  self.mySubview.layer.mask = maskLayer;

}

I had to override drawRect: in my UITableViewCell subclass and set the mask layer there.

I have had same problem and doing things in - (void)drawRect:(CGRect)rect does the work but it could be costly in terms of performance.

You can call your clipping or shadow methods in perform selector

[self performSelector:@selector(<your drawing method>) withObject:nil afterDelay:0.0000001 ];//a very low delay
