Question

在我的应用中，我在添加联系人页面中有选择浏览量。我给出了以下'touchesBegan'方法。但即使我点击要设置的值，它也会取消选择器。例如，如果我从首选电话选择器点击“家庭电话”，则选择器将被解除而不是设置该值。只有当我在选择器外面点击时，我才需要解雇选择器。任何人都可以帮我解决这个问题。

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
 [self.AddView endEditing:YES];
}

Answer 1

您可以使用

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
  UITouch *touch = [touches anyObject];
  if ([touch view] != pickerview)
     [self.AddView endEditing:YES];
}

当触摸位于选择器视图之外时，这将用于结束

Answer 2

在您的代码中：

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

 [self dismissViewControllerAnimated:YES completion:nil];

}

或者您可以在PickerView下放置一个更大的按钮，使其颜色清晰自定义并且全屏尺寸，然后使用(IBAction)内的消除，当您在选择器外部点按时，您的视图将被解除

- (IBAction)buttonClear:(id)sender {

[self dismissViewControllerAnimated:YES completion:nil];

}

Answer 3

试试这段代码：

UITapGestureRecognizer *single_tap_recognizer;

    single_tap_recognizer = [[[UITapGestureRecognizer alloc]
                              initWithTarget : self.view
                              action         : @selector(upper_button_view_tapped)]
                             autorelease];

    [single_tap_recognizer setNumberOfTouchesRequired : 1];
    [self.view addGestureRecognizer : single_tap_recognizer];

-(void)upper_button_view_tapped
{
 [self .view endEditing:YES];
}
