Swift、Xcode:单击时更改 UIButton 背景和文本 [英] Swift, Xcode: Changing UIButton Background and Text on Click

问题描述

我想在单击时更改按钮的背景和文本，我尝试了几种 SO 解决方案，但没有奏效，您可以查看我在项目中尝试的内容:

2) 这样做:

@IBAction func 更改(发送方:UIButton){button.backgroundColor = UIColor.blueColor()button.setTitle("按钮标题", forState: UIControlState.Normal)}

I want to change the background and text of the button on click, I tried several SO solutions but they haven't worked, you can see what I tried in my project: https://github.com/jzhang172/modalTest

I tried debugging it by putting a simple print statement and it looks like it doesn't ever go to it.

解决方案

SOLUTION:

1) Create an IBAction from your UIButton and also an IBOutlet called button.

EDIT: As per your request (How to trigger the even when the button is TOUCHED, not RELEASED?):

2) Do this:

@IBAction func changes (sender: UIButton) {

    button.backgroundColor = UIColor.blueColor()

    button.setTitle("Button Title", forState: UIControlState.Normal)

}
