ios - 如何在 swift 4 中隐藏 SexyTooltip？

Question

我正在尝试在我的 swift 项目中使用 SexyTooltip。我有这段代码:

func showTooltip(prefix: Int?){
        var description = ""

        description = setProductIconTitle(prefix: prefix)

        let myAttribute = [ NSAttributedStringKey.foregroundColor: UIColor.black,  NSAttributedStringKey.backgroundColor: .white]
        let greetingsText = NSAttributedString(string: description, attributes: myAttribute)

        let greetingsTooltip = SexyTooltip(attributedString: greetingsText, sizedTo: view, withPadding: UIEdgeInsetsMake(10, 5, 10, 5), andMargin: UIEdgeInsetsMake(20, 20, 20, 20))
        greetingsTooltip?.dismiss(inTimeInterval: 2)
        view.addSubview(greetingsTooltip!)

        greetingsTooltip?.present(from: iconView1, in: view, withMargin: 10, animated: true)
    }

这段代码工作正常。我想一次只看到一个提示/工具提示。单击另一个按钮后 - 所有以前的提示/工具提示都必须隐藏。

怎么做？

试试这个

func showTooltip(prefix: Int?){

    for toolView in view.subviews {
        if toolView is SexyTooltip {
            toolView.removeFromSuperview()
        }
    }
    var description = ""
    description = setProductIconTitle(prefix: prefix)
    let myAttribute = [ NSAttributedStringKey.foregroundColor: UIColor.black,  NSAttributedStringKey.backgroundColor: .white]
    let greetingsText = NSAttributedString(string: description, attributes: myAttribute)

    let greetingsTooltip = SexyTooltip(attributedString: greetingsText, sizedTo: view, withPadding: UIEdgeInsetsMake(10, 5, 10, 5), andMargin: UIEdgeInsetsMake(20, 20, 20, 20))
    greetingsTooltip?.dismiss(inTimeInterval: 2)
    view.addSubview(greetingsTooltip!)

    greetingsTooltip?.present(from: iconView1, in: view, withMargin: 10, animated: true)
}
