Question

在iPhone应用程序中，我有UITextField需要输入作为数字，所以我将键盘类型传递为UIKeyboardTypeNumberPad。它有效，但没有返回或完成按钮，所以我怎么能隐藏键盘。

参考代码是：

textDriverAge.delegate=self;
textDriverAge.keyboardType=UIKeyboardTypeNumberPad;
textDriverAge.clearButtonMode = UITextFieldViewModeWhileEditing;
[textDriverAge setReturnKeyType:UIReturnKeyDone];// UIReturnKeyNext];
textDriverAge.enablesReturnKeyAutomatically=TRUE;

我处理了UITextfield事件，例如：

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


if(textDriverAge == textField)
{
    [textDriverAge resignFirstResponder];

    //[tglDropInDropOff becomeFirstResponder];
}

}

指导我如何隐藏键盘。

Answer 1

你可以使用两种类型

Touch Method。

在另一个选项中，在视图控制器中添加UIToolbar。

- (void)viewDidLoad

{
[super viewDidLoad];

UIToolbar  *numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
numberToolbar.items = [NSArray arrayWithObjects:
                       [[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelNumberPad:)],
                       [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                       [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad:)],
                       nil];
yourtextField.inputAccessoryView = numberToolbar;

 }


- (IBAction)cancelNumberPad:(UITextField*)textField
{
 [yourtextField resignFirstResponder];
    yourtextField.text=@"";
}


- (IBAction)doneWithNumberPad:(UITextField*)textField 
{
[yourtextField resignFirstResponder];
}

试试这个..： - ）

- (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];
}

您需要将inputAccesoryView放入文本字段并向其添加完成按钮。在这里，我创建了一个xib名称'InputAccessoryView'，并根据我的需要进行设计。你也可以这样做......

        InputAccessoryView *inputAccessoryView=(InputAccessoryView *)[[[NSBundle mainBundle] loadNibNamed:@"InputAccessoryView" owner:self options:nil] objectAtIndex:0];
        [inputAccessoryView.doneButton setTarget:self];
        [inputAccessoryView.doneButton setAction:@selector(accessoryDoneAction:)];

        [inputAccessoryView.cancelButton setTarget:self];
        [inputAccessoryView.cancelButton setAction:@selector(acessoryCancelButtonAction:)];


[self.textField setInputAccessoryView:inputAccessoryView];

Answer 4

添加以下代码以在numberpad上添加返回按钮

- (void)viewDidLoad 

{
[super viewDidLoad];

UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
numberToolbar.barStyle = UIBarStyleBlackTranslucent;
numberToolbar.items = [NSArray arrayWithObjects:
                     [[UIBarButtonItem alloc]initWithTitle:@"Return" style:UIBarButtonItemStyleBordered target:self action:@selector(returnNumberPad)],
                 nil];
[numberToolbar sizeToFit];
numberTextField.inputAccessoryView = numberToolbar;

 }

-(void)returnNumberPad
{
[numberTextField resignFirstResponder];
}

隐藏类型为UIKeyboardTypeNumberPad objective c的键盘
