iOS Set shadow radius is not working

Question

UILabel set shadow radius is not working.

[self.testLabel.layer setShadowColor:[[UIColor purpleColor] CGColor]];
[self.testLabel.layer setShadowOffset:CGSizeMake(3, 3)];
[self.testLabel.layer setShadowRadius:5.0f];
[self.testLabel.layer setMasksToBounds:YES];

My code (Google Drive) https://drive.google.com/file/d/0B5UPvOBH3cqvOFlvZHhKdlNhb0E/view?usp=sharing

I'm sorry if this's a repeat question. Thanks a lot.

Answer 1

because of the [self.testLabel.layer setMasksToBounds:YES];

this method will make the shadow invisible, you can make a shadow image with a png/jpg formate, and put a imageview that had set the image below your textLabel to make it work..

and also you should set the opacity to 1..

//    self.testLabel.backgroundColor = [UIColor grayColor];
    self.testLabel.layer.shadowOpacity = 1.0f;
    [self.testLabel.layer setShadowColor:[[UIColor yellowColor] CGColor]];
    [self.testLabel.layer setShadowOffset:CGSizeMake(3, 3)];
    [self.testLabel.layer setShadowRadius:5.0f];
//    [self.testLabel.layer setMasksToBounds:YES];

try this ..
