如何用Apple的新语言实现它？
Objective-C代码：
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
for (UIView *view in self.view.subviews)
[view resignFirstResponder];
}
我试图这样做.但是键盘并没有消失：
SWIFT代码：
override func touchesBegan(touches: NSSet,withEvent event: UIEvent) {
super.touchesBegan(touches,withEvent: event)
self.view.resignFirstResponder()
}
你可能会去：
self.view.endEditing(true)
