ios - touchesBegin 有时不被调用

Question

我touchesBegan在初始登录 ViewController 中有关闭键盘并取消自定义 AlertView。虽然它最初有效，但touchesBegan在我注销后没有被调用performSegueWithIdentifier。

//to resign keyboard
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        println("touchesBegan");
        self.view.endEditing(true)
       loginAlert.hideView()
       signupAlert.hideView()
}

//Logout
self.performSegueWithIdentifier("gotoLoginSegue", sender: self);

Answer 1

问题是因为我同时使用了UITapGestureRecognizer和touchesBegan。我处理了场景UITapGestureRecognizer并删除了touchesBegan逻辑并修复了
