touchesbegan/moved/ended not working with xcode 6.3
提问by user3302800
I'm having the same problem as listed with the beta 6.3 here: Overriding method with selector 'touchesBegan:withEvent:' has incompatible type '(NSSet, UIEvent) -> ()'
我遇到了与此处列出的 beta 6.3 相同的问题：使用选择器 'touchesBegan:withEvent:' 的覆盖方法具有不兼容的类型 '(NSSet, UIEvent) -> ()'
but the fixes listed there are not working for me. I've changed this line:
但是那里列出的修复程序对我不起作用。我改变了这一行：
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
to this:
对此：
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
The error I'm getting is: "Method does not override any method from its superclass"
我得到的错误是：“方法不会覆盖其超类中的任何方法”
Does anyone know if the fixes listed above for the 6.3 beta are really working with the final 6.3?
有谁知道上面列出的 6.3 测试版修复程序是否真的适用于最终的 6.3？

So I found the answer to my own question ... this was caused by a class I had already defined in my project called "Set". (that was from a tutorial from Ray W about making a candy crush game). Anyway, in Swift 1.2 they introduced their own class called "Set" and it was causing name collision problems. So I just renamed the old Set class and it all started working. UGH!
所以我找到了我自己问题的答案......这是由我在我的项目中定义的一个名为“Set”的类引起的。（这是来自 Ray W 关于制作糖果粉碎游戏的教程）。无论如何，在 Swift 1.2 中，他们引入了自己的名为“Set”的类，这导致了名称冲突问题。所以我只是重命名了旧的 Set 类，它就开始工作了。啊！

Here is the complete code for touchesBegan there is also change in accessing UITouch object.
这是 touchesBegan 的完整代码，访问 UITouch 对象也有变化。
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
super.touchesBegan(touches, withEvent: event);
mouseSwiped = false
let array = Array(touches)
let touch = array[0] as! UITouch
currentLocation = touch.locationInView(imgViewSignature)
currentLocation.y += 0
}

Here is my simple code.
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
super.touchesBegan(touches, withEvent: event);
usernameTF.resignFirstResponder()
passwordTF.resignFirstResponder()
self.view.endEditing(true)
}
