UIButton插座集标题Swift

Question

I have set up an outlet as follows using a storyboard:

@IBOutlet var completeButton: UIButton!



self.completeButton.titleLabel = UIFont (name: standardFont, size: 22.0)

give the error cannot assign to the result of this expression.

Simple task but can't seem to get round this in swift.

Answer 1

You are missing out the font property and titleLabel needs to be unwrapped. Try the following:

self.completeButton.titleLabel!.font = UIFont.systemFontOfSize(22.0)

Answer 2

@Melvin Wijenayaka: For your example, the UIFont constructor contains two parameters this will also work for you

self.completeButton!.titleLabel.font = UIFont(name: "System", size: 22.0)

Note: You missed out the property font in your code.
