Override func Error! Method does not override any method from its superclass
提问by user6083214
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
}
override func supportedInterfaceOrientations() -> Int {
}
Here I have an error. It says
这里我有一个错误。它说
Method does not override any method from its superclass.
方法不会覆盖其超类中的任何方法。
This comes multiple times, I can't fix it.
多次出现这种情况，我无法解决。
Do you know something about it?
你知道吗？

The error is coming because your method signature is different than the actual ones. You should use the exact method signature for overriding (Either you should use auto-complete feature provided in Xcode or refer the documentation)
错误即将到来，因为您的方法签名与实际签名不同。您应该使用确切的方法签名进行覆盖（您应该使用 Xcode 中提供的自动完成功能或参考文档）
接触开始：
override func touchesBegan(_ touches: Set<UITouch>,
with event: UIEvent?)
{
}
In Swift 3 supportedInterfaceOrientationsis no longer a method, it's a computed property, so it's signature becomes:
在 Swift 3 中，supportedInterfaceOrientations不再是一个方法，它是一个计算属性，所以它的签名变成：
override var supportedInterfaceOrientations : UIInterfaceOrientationMask
{
}
