你可以试试这个按钮和视图https://github.com/malcommac/CMPopTipView它就像一个魅力！ （此代码用于按钮，但与 UIGestureRecognizer 的 uimageview 相同）

class ViewController: UIViewController, SwiftPopTipViewDelegate {
var roundRectButtonPopTipView: SwiftPopTipView?

@IBAction func buttonAction(_ sender: UIButton) {
    // Toggle popTipView when a standard UIButton is pressed
    if let _ = roundRectButtonPopTipView {
        // Dismiss
        roundRectButtonPopTipView?.dismissAnimated(true)
        roundRectButtonPopTipView = nil
    } else {
        roundRectButtonPopTipView = SwiftPopTipView(message: "My message")
        roundRectButtonPopTipView?.delegate = self
        roundRectButtonPopTipView?.popColor = UIColor.lightGray
        roundRectButtonPopTipView?.textColor = UIColor.darkText

        roundRectButtonPopTipView?.presentPointingAtView(sender as! UIView, containerView: view, animated: true)
    }
}

//MARK: - SwiftPopTipViewDelegate methods
func popTipViewWasDismissedByUser(popTipView: SwiftPopTipView) {
    // User can tap SwiftPopTipView to dismiss it
    roundRectButtonPopTipView = nil
}
}
