Ios 使用UIKeyboardTypeNumberPad objective c类型隐藏键盘

在iPhone应用程序中，我有一个

UITextField

，需要作为数字输入，因此我将键盘类型作为

UIKeyboardTypeNumberPad

传递。它可以工作，但没有返回或完成按钮，所以我如何才能隐藏键盘

参考代码为：

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

我处理过

UITextfield

事件，如：

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


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

    //[tglDropInDropOff becomeFirstResponder];
}

}

指导我如何隐藏键盘。

您需要将InputAccessoryView放入文本字段，并向其添加“完成”按钮。在这里，我制作了一个xib名称“InputAccessoryView”，并根据我的需要进行了设计。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];

您可以使用两种类型

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];
}

添加以下代码以添加numberpad上的返回按钮

- (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];
}

试试这个…-）

创建一个带有按钮和

[textDriverAge setInputAccessoryView:toolbar]
