UIKeyboardTypeNumberPad 数字键盘添加完成按钮
一:添加通知
//数字键盘添加完成
[[NSNotificationCenterdefaultCenter] addObserver:selfselector:@selector(keyboardWillShow:) name:UIKeyboardDidShowNotificationobject:nil];
二:数字键盘出现添加
//键盘处理 - ( void )keyboardWillShow:( NSNotification *)note { UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom]; doneButton.frame = CGRectMake(15, 172, 65, 35); //doneButton.frame = CGRectMake(8, 163, 50, 30); //[doneButton setTitle:@"完成" forState:UIControlStateNormal]; [doneButton setBackgroundImage:[UIImage imageNamed:@ "pickerBackIMG.png" ] forState:UIControlStateNormal]; [doneButton addTarget: self action: @selector (doneBtn) forControlEvents:UIControlEventTouchUpInside]; UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1]; UIView* keyboard; for ( int i=0; i<[tempWindow.subviews count]; i++) { keyboard = [tempWindow.subviews objectAtIndex:i]; // keyboard view found; add the custom button to it if (([[keyboard description] hasPrefix:@ "<UIPeripheralHostView" ] == YES ) ||(([[keyboard description] hasPrefix:@ "<UIKeyboard" ] == YES ))) [keyboard addSubview:doneButton]; } } - ( void )doneBtn { [phoneNumTextField resignFirstResponder]; } |
三:移除通知
- (void)dealloc
{
[[NSNotificationCenterdefaultCenter]removeObserver:selfname:UIKeyboardDidShowNotificationobject:nil];
[kDatePickerrelease];
[super dealloc];
}
