Swift将多个图像添加到单个UIButton中

Question

在我的应用程序中，我想在单个UIButton上添加多个图像。

这是我现在有：

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) 

我想将第二图象作为一个箭头指向下一个页面。 在此先感谢:)

按钮作品的其余部分，但我不知道如何使箭头出现

我在这里固定的问题是新代码：

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) 

通过只需将setImage添加到代码中，我就可以在BackgroundImage的顶部创建第二个图像。然后通过起诉imageEdgeInsets我对齐按钮上的图像。
