我的手势有点麻烦。
我正在尝试在同一按钮上同时使用水龙头和长按,所以我使用了
@IBAction func xxx (sender: UITapGestureRecognizer)
和
@IBAction func xxx (sender: UILongPressGestureRecognizer)
但是当我点击时,我的按钮似乎对这两种功能都有反应。有什么问题吗?
func long(longpress: UIGestureRecognizer){
if(longpress.state == UIGestureRecognizerState.Ended){
homeScoreBool = !homeScoreBool
}else if(longpress.state == UIGestureRecognizerState.Began){
print("began")
}
}
很难说什么与您的代码不兼容,仅提供了两行,但我建议您以这种方式进行:
为按钮创建插座
@IBOutlet weak var myBtn: UIButton!
然后viewDidLoad()
将手势添加到按钮中
let tapGesture = UITapGestureRecognizer(target: self, action: "normalTap")
let longGesture = UILongPressGestureRecognizer(target: self, action: "longTap:")
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)
然后创建动作来处理水龙头
func normalTap(){
print("Normal tap")
}
func longTap(sender : UIGestureRecognizer){
print("Long tap")
if sender.state == .Ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .Began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}
Swift 3.0版本:
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.normalTap))
let longGesture = UILongPressGestureRecognizer(target: self, action: Selector(("longTap:")))
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)
func normalTap(){
print("Normal tap")
}
func longTap(sender : UIGestureRecognizer){
print("Long tap")
if sender.state == .ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}
Swift 5.x的更新语法:
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(normalTap))
button.addGestureRecognizer(tapGesture)
let longGesture = UILongPressGestureRecognizer(target: self, action: #selector(longTap))
button.addGestureRecognizer(longGesture)
@objc func normalTap(_ sender: UIGestureRecognizer){
print("Normal tap")
}
@objc func longTap(_ sender: UIGestureRecognizer){
print("Long tap")
if sender.state == .ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}
