Swift 将多个图像添加到单个 UIButton [英] Swift adding multiple images to a single UIButton

问题描述

在我的应用程序中，我想在一个 UIButton 上添加多个图像.

In my app, I would like to add multiple images on a single UIButton.

这就是我现在所拥有的:

This is what I have now:

    NextButton = UIButton(frame: CGRect(x: width*0, y: height*0.55, width: width*0.95, height: height*0.05))
    NextButton.addTarget(self, action: #selector(OnNextPressed), for: .touchUpInside)
    NextButton.isExclusiveTouch = true
    NextButton.setTitle("ButtonText", for: UIControlState())
    NextButton.setTitleColor(UIColor(red:0, green:0, blue:0, alpha:1.0), for: UIControlState())
    NextButton.setBackgroundImage(UIImage(named: "ButtonOutline"), for: .normal)
    view.addSubview(NextButton)

我想要第二张图片作为指向下一页的箭头.提前致谢:)

I would like a 2nd image as an arrow pointing to the next page. thanks in advance :)

按钮的其余部分有效，但我不知道如何使箭头出现

the rest of the button works but I don't know how to make the arrow appear

推荐答案

我在这里修复了新代码:

I fixed the problem here is the new code:

    let screenSize: CGRect = UIScreen.main.bounds

    let width = screenSize.width
    let height = screenSize.height

NextButton = UIButton(frame: CGRect(x: width*0, y: height*0.55, width: width*0.95, height: height*0.05))
NextButton.addTarget(self, action: #selector(OnNextPressed), for: .touchUpInside)
NextButton.isExclusiveTouch = true
NextButton.setTitle("ButtonText", for: UIControlState())
NextButton.setTitleColor(UIColor(red:0, green:0, blue:0, alpha:1.0), for: UIControlState())
NextButton.setBackgroundImage(UIImage(named: "ButtonOutline"), for: .normal)
NextButton.setImage(UIImage(named: "arrow_next"), for: UIControlState())
NextButton.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, width*0.7)
view.addSubview(NextButton)

通过简单地将 setImage 添加到代码中，我可以在 BackgroundImage 之上创建第二个图像.然后通过起诉 imageEdgeInsets 我对齐按钮上的图像.

by simply adding setImage to the code i could create a second image on top of the BackgroundImage. then by suing imageEdgeInsets i aligned the image on the button.
