ios - iphone:键盘没有隐藏

Question

我有一种情况，我有一个警报 View ，其中以编程方式绘制了一个文本字段

UIAlertView *alertView=[[UIAlertView alloc] initWithTitle:@"Welcome" message:@"Enter you name" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

    nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];

    [nameField setBorderStyle:UITextBorderStyleRoundedRect];
    [nameField setPlaceholder:@"Enter Owners name"];
    [nameField setTextAlignment:UITextAlignmentCenter];
    [nameField setDelegate:self];
    [nameField setBackgroundColor:[UIColor clearColor]];

    [alertView addSubview:nameField];
    CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, -80.00);
    [alertView setTransform: moveUp];

    [alertView show];
    [alertView release];

为了隐藏我用过的键盘

- (BOOL)textFieldShouldReturn:(UITextField *)textField{

[textField resignFirstResponder];
return YES;

但键盘没有隐藏。请帮助我。

Answer 1

您可以使用它隐藏您的键盘。单击您的模拟器/仿真器/iOS 设备的背景时，这将起作用。

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

            [yourtextfield resignFirstResponder];

            // you can have multiple textfields here


        }
