Question

我有两个文本字段，一个用于用户名，第二个用于移动电话号码

用户名：我可以使用此方法隐藏用户名Text-Fields的键盘

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

我的问题是手机号码：

如何隐藏移动电话号码文字字段？

Answer 1

您可以使用以下library在数字键盘上添加完成和取消按钮。

此外，您可以使用点按手势隐藏数字键盘。使用以下代码：

 - (void)viewDidLoad
{

UITapGestureRecognizer* tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(dismissKeyboard)];
tapGesture.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGesture];
}

-(void)dismissKeyboard
 {
 [textField resignFirstResponder];//Assuming that UITextField Object is textField
 }

这对你有用..快乐的编码!!干杯.. !!

Answer 2

 - (void)viewDidLoad
{
    [self addTapGesture];
}

#pragma mark
#pragma mark Gesture  methods

- (void) addTapGesture {
    UITapGestureRecognizer *tapper = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    tapper.cancelsTouchesInView = FALSE;
    [self.view addGestureRecognizer:tapper];
}

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

Answer 3

使用

textField.keyboardType = UIKeyboardTypeNumberPad;

Answer 4

您可以选择几个选项，您需要决定何时关闭文本字段数字键盘。例如，如果您在解雇之前需要一定数量的数字，则可以订阅

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(textFieldTextDidChange:) name:UITextFieldTextDidChangeNotification object:nil];

然后按照

的方式实施

-(void)textFieldTextDidChange:(NSNotification *)notification
{
    UITextField *textfield = notification.object;

    if(textfield.text.length == NUMBER_OF_DIGITS_NEEDED)
        [textField resignFirstResponder];
}

如果您的用户还需要自行决定关闭键盘，则应在剩余的可见视图上放置一个水龙头手势识别器。

UITapGestureRecognizer *tapGestureRecogniser = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture:)];
tapGestureRecogniser.delegate = self;
[self.view addGestureRecognizer:tapGestureRecogniser];

-(void)handleTapGesture:(UITapGestureRecognizer *)tapGestureRecogniser
{
    if ([self.myTextField isFirstResponder])
        [self.myTextField resignFirstResponder];
}
