Question

I have a UIView for which I would like to set its borderColor:

UIView *myView = ...;
myView.layer.borderWidth = 1;
myView.layer.borderColor = [UIColor greenColor].CGColor;

Is it safe to do it like this?
The UIColor object will be autoreleased and with it the CGColor object. Now, does the borderColor property retain the CGColor so that it is safe to let the UIColor be autoreleased, or do I have to retain the UIColor in a separate instance variable?

Answer 1

The CGColor is not an object in the same sense as UIColor, but the layer would retain it using CGColorRetain() so this is fine
