NSNotification无法找到选择器

Question

我通过默认中心发布通知，如下所示：

NSNotificationCenter.defaultCenter().postNotificationName(ColorDidGetTappedNotification, object: self)

我在另一个例子中观察通知，如下所示：

NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("colorDidGetTapped:"), name: ColorDidGetTappedNotification, object: nil)
....
func colorDidGetTapped(notification: NSNotification) {
    println("Notification recieved")
}

但是我得到一个无法识别的选择器异常：

更新1

*** NSForwarding: warning: object 0x7d564490 of class '_D.GameModel' does not implement methodSignatureForSelector: -- trouble ahead
Unrecognized selector -[_D.GameModel colorDidGetTapped:]

Answer 1

检查GameModel是NSObject的子类

class GameModel: NSObject {

}

Answer 2

尝试使用此方法观察通知：addObserverForName(_:object:queue:usingBlock:)。而不是选择器传递块
