IOS-判斷顯示的哪個鍵盤

使用UITextField創建了一個應用，在用戶輸入的時候顯示十進鍵盤。

我想自己添加完成鍵：

[ [NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWillShow:)
                                             name:UIKeyboardWillShowNotification
                                           object:nil];

鍵盤運行正常，但是問題是在UIView中有另一個textField，我不想在這個添加done按鈕。

怎麼檢測十進鍵盤和常規鍵盤？

最佳回答：

使用textField的inputAccessoryView屬性：

txtfld.keyboardType=UIKeyboardTypeDecimalPad;
txtfld.inputAccessoryView=[self toolBarForKeyboardAccessory];

然後：

    -(UIToolbar *)toolBarForKeyboardAccessory
    {
     UIToolbar *keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
     keyboardToolbar.barStyle = UIBarStyleDefault;

    UIBarButtonItem* flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];


UIBarButtonItem* cancelButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelButtonClicked:)];
 CGRect rect = CGRectMake(1, 5.0, 250, 30);
KeyboardTextField = [[UITextField alloc] initWithFrame:rect];
KeyboardTextField.borderStyle = UITextBorderStyleRoundedRect;
KeyboardTextField.font = [UIFont systemFontOfSize:17.0];
KeyboardTextField.delegate = self;

 UIBarButtonItem *textFieldItem = [[UIBarButtonItem alloc] initWithCustomView:KeyboardTextField] ;

[keyboardToolbar setItems:[NSArray arrayWithObjects: flexSpace,textFieldItem,flexSpace, cancelButton,flexSpace, nil] animated:NO];

return keyboardToolbar;
}
