[Solved] Property 'cornerRadius' cannot be found in forward class object 'CALayer *'

When I tried the following:

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectZero];
myLabel.layer.cornerRadius = 2.0f;
[myLabel release];

I get an error: Property 'cornerRadius' cannot be found in forward class object 'CALayer *'

The solution is to import the QuartzCore framework:

#import <QuartzCore/QuartzCore.h>

Happy coding!
