- (IBAction)loopBtn:(id)sender {
    loopBtn.keyboardType = UIKeyboardTypeNumberPad;
    [loopBtn becomeFirstResponder];

Answer 1

UIView您可以通过使您的 an UIControl( UIControlis subclass of UIView)来隐藏键盘。然后编写一个IBAction在您触摸它时执行的方法UIControl（以前UIView）。打开界面编辑器并选择 main UIView。然后打开身份检查器并将其类更改为UIControlfrom UIView。现在在您的视图控制器中编写一个 IBAction 方法。

-(IBAction)hideKeyboard:(id)sender
{
    [self.view endEditing:YES];
}

现在将您的 UIView 的 TouchUpInside 事件连接到此 IBAction 方法。每当您在文本字段之外触摸时，这将隐藏键盘。
