uiappearance

I have been getting unreliable results while trying to apply UIAppearance proxy styles to the UILabel class proxy. For example, the following works as I would expect: [[UILabel appearance] setFont:[UIFont fontWithName:SOME_FONT size:SOME_SIZE]]; [[UILabel appearance] setShadowColor:[UIColor blackColor]]; Setting the textColor doesn't work, however, this: [[UILabel appearance] setColor:[UIColor greenColor]]; does work. Kind of . It's somewhat unreliable and causes any instance-specific calls to setTextColor: to be ignored. What is the correct way to apply UIAppearance styles to a UILabel? OK,

Update for iOS 9: If you're targeting iOS 9+ (as of Xcode 7 b1), there is a new method in the UIAppearance protocol which does not use varargs: static func appearanceWhenContainedInInstancesOfClasses(containerTypes: [AnyObject.Type]) -> Self Which can be used like so: UITextField
