iOs: Programmatically change the ratio of a UILabel in Swift

Question

I want to change programmatically the ratio of a UILabel to have something adapted between devices (iPhone 4, 5, 6, iPad), because I can't on the StoryBoard:

    if DeviceType.IS_IPHONE_4_OR_LESS {
    } else if DeviceType.IS_IPHONE_5 {
    } else if DeviceType.IS_IPHONE_6 {
    } else if DeviceType.IS_IPHONE_6P {
    } else if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
    }

Answer 1

The multiplier property (the ratio) is readonly. You should add support for size classes in your constraints by pressing the + sign beside the Installed check box. Thus, you can specify different constraints for different size classes.
