我尝试在我的视图中为现有按钮添加手势(滑动)功能,但我无法弄清楚如何将滑动附加到按钮区域。
理想的效果是有一个我可以按下的按钮以及滑动以产生不同的结果。到目前为止,我实现手势的方式将其应用于我的整个视图而不仅仅是按钮。
我觉得这很简单,但它已经逃脱了我几天 - 我可能只是在寻找错误的东西。
(我正在分配' @IBOutlet var swipeButton:UIButton!'到我的按钮BTW)
以下代码:
class ViewController: UIInputViewController {
@IBOutlet var swipeButton: UIButton!
let swipeRec = UISwipeGestureRecognizer()
override func viewDidLoad() {
super.viewDidLoad()
self.loadInterface()
var swipeButtonDown: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "ButtonDown")
swipeButtonDown.direction = UISwipeGestureRecognizerDirection.Down
self.view.addGestureRecognizer(swipeButtonDown)
}
@IBAction func buttonPressed(sender: UIButton) {
var proxy = textDocumentProxy as UITextDocumentProxy
proxy.insertText("button")
}
func buttonDown(){
var proxy = textDocumentProxy as UITextDocumentProxy
proxy.insertText("swipe")
}
}
答案 0 :(得分:6)
如果你想将swipeGesture添加到Button中,那就这样做:
self.yourButton.addGestureRecognizer(swipeButtonDown)
并且您发送的选择器中也存在错误:
var swipeButtonDown: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "buttonDown")
将ButtonDown
更改为buttonDown
