在Swift中更改按钮的字体

Question

I know this question has been asked before, and the question seemed to be solved, but I have an issue that I can't seem to solve. I'm trying to change to font of a UIButton using

advanceButton.titleLabel!.font = UIFont (name: "ArchitectsDaughter", size: 17)

However, when I use this I get a compile message that

(AnyObject) ->() Does not have a member named 'titleLabel'

I've tried both the implicit, normal, and optional types for titleLabel but nothing will fix this. Can someone help me please? Thanks in advance!

Answer 1

Your advanceButton is not of type UIButton.

When you define advanceButton make sure it is of type UIButton.

like so,

var advanceButton : UIButton = UIButton()
advanceButton.titleLabel!.font = UIFont(name: "Times New Roman", size: 25)

Answer 2

这看起来像你要么有一个名为方法advanceButton即与命名变量碰撞advanceButton或代替定义@IBOutlet为您的按钮，你定义的@IBAction 。
