Hide button in Swift 3
提问by J. Aberson
I've just started with coding and I really want to know how to hide buttons.
我刚刚开始编码，我真的很想知道如何隐藏按钮。
What I want to do is when I press my button:
我想做的是当我按下按钮时：
Start:I want to let the start button and the back button disappear.

It's done with Outlets and Actions.
它是通过 Outlets 和 Actions 完成的。
I already searched a bit but when I wanted to do it, it said that the dokeyword is expected to designate a block of statements.
我已经搜索了一点，但是当我想搜索时，它说do关键字应该指定一个语句块。
I hope someone can help me out.

Once you have your outlets connected, simply change the isHiddenproperty to true.
连接好插座后，只需将isHidden属性更改为 true。
IBOutlet weak var startButton: UIButton
IBOutlet weak var backButton: UIButton
IBAction func tapStart(sender: AnyObject?){
self.startButton.isHidden = true
self.backButton.isHidden = true
}
