custom keyboard

1) Overlay an image.
2) Overlay a button.

And you’re done. Here’s the code I used:

- (void)textFieldDidBeginEditing:(UITextField *)textField

{

// locate keyboard view

UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];

UIView* keyboard;

UIImageView *decimalKeyboard = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 216)];

decimalKeyboard.image = [UIImage imageNamed:@"decimal_keyboard.png"];

UIButton *decimalButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 165, 105, 53)];

[decimalButton addTarget:self action:@selector(decimalButtonPressed:)forControlEvents:UIControlEventTouchUpInside];

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:@”<UIKeyboard”] == YES)

{

[keyboard addSubview:decimalKeyboard];

[keyboard addSubview:decimalButton];

}

}

[decimalKeyboard release];

[decimalButton release];

}

3.1.x에서는 windows 서브뷰에 항상 키보드 뷰가 있었지만 ...
4.0 부터는 windows 에 항상 있는게 아니고, 키보드를 불렀을때 -_- 붙어서 오더라고요.. 그래서

Done 버튼 붙이는 예제 입니다. (Number 패드에)

아래 액션을 Text필드의 BeginTouched 에 연결 시킵니다.
 // 키보드가 나왔을때랑 사라질때의 이벤트를 잡아냅니다.
//3.1.X 에서는 UIKeyboardWillShowNotification 으로 잡지만
// 4.0 때문에 --; DidShow로 잡아줬습니다.
//그래야 윈도우에 키보드가 있더라고요 ;;;
