私はテキストフィールドがあるアプリケーションを持っています。それをクリックすると画面がスクロールし、キーボードが表示されます。私はこのコードを使用します。キーボードに完了ボタンを追加するにはどうすればいいですか？
- (void) viewWillAppear:(BOOL)animated {
UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
[self willAnimateRotationToInterfaceOrientation:orientation duration:0];
[super viewWillAppear:animated];
NSLog(@"Registering for keyboard events");
// Register for the events
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector (keyboardDidShow:) name: UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector (keyboardDidHide:) name: UIKeyboardDidHideNotification object:nil];
// Setup content size
scrollView.contentSize = CGSizeMake(SCROLLVIEW_CONTENT_WIDTH,SCROLLVIEW_CONTENT_HEIGHT);
//Initially the keyboard is hidden
keyboardVisible = NO;
}
- (void)keyboardWillShow:(NSNotification *)note {
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for (keyboard in tempWindow.subviews) {
if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
if (numberPadShowing) {
[self addButtonToKeyboard];
return;
break;
} else {
for (UIView *v in [keyboard subviews]){
if ([v tag]==123)
[v removeFromSuperview];
}
}
}
}
-(void) keyboardDidShow: (NSNotification *)notif {
NSLog(@"Keyboard is visible");
// If keyboard is visible, return
if (keyboardVisible)
{
NSLog(@"Keyboard is already visible. Ignore notification.");
return;
}
// if clause is just an additional precaution, you could also dismiss it
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
[self addButtonToKeyboard];
}
// Get the size of the keyboard.
NSDictionary* info = [notif userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
// Save the current location so we can restore
// when keyboard is dismissed
offset = scrollView.contentOffset;
// Resize the scroll view to make room for the keyboard
CGRect viewFrame = scrollView.frame;
viewFrame.size.height -= keyboardSize.height;
scrollView.frame = viewFrame;
UIInterfaceOrientation toInterfaceOrientation = [[UIDevice currentDevice] orientation];
if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
CGRect textFieldRect = [myActiveTextField frame];
textFieldRect.origin.y += 20;
[scrollView scrollRectToVisible:textFieldRect animated:YES];
} else {
CGRect textFieldRect = [myActiveTextField frame];
textFieldRect.origin.y += 80;
[scrollView scrollRectToVisible:textFieldRect animated:YES];
}
NSLog(@"ao fim");
// Keyboard is now visible
keyboardVisible = YES;
}
-(void) keyboardDidHide: (NSNotification *)notif {
// Is the keyboard already shown
if (!keyboardVisible) {
NSLog(@"Keyboard is already hidden. Ignore notification.");
return;
}
// Reset the frame scroll view to its original value
scrollView.frame = CGRectMake(0, 44, SCROLLVIEW_CONTENT_WIDTH, SCROLLVIEW_CONTENT_HEIGHT);
// Reset the scrollview to previous location
scrollView.contentOffset = offset;
// Keyboard is no longer visible
keyboardVisible = NO;
}
- (void)addButtonToKeyboard {
// create custom button
UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
UIInterfaceOrientation toInterfaceOrientation = [[UIDevice currentDevice] orientation];
if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
doneButton.frame = CGRectMake(0, 260, 160, 40);
} else {
doneButton.frame = CGRectMake(0, 163, 106, 53);
}
doneButton.adjustsImageWhenHighlighted = NO;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.0) {
[doneButton setImage:[UIImage imageNamed:@"DoneUp3.png"] forState:UIControlStateNormal];
[doneButton setImage:[UIImage imageNamed:@"DoneDown3.png"] forState:UIControlStateHighlighted];
} else {
[doneButton setImage:[UIImage imageNamed:@"DoneUp.png"] forState:UIControlStateNormal];
[doneButton setImage:[UIImage imageNamed:@"DoneDown.png"] forState:UIControlStateHighlighted];
}
[doneButton addTarget:self action:@selector(doneButton) forControlEvents:UIControlEventTouchUpInside];
// locate keyboard view
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i=0; i<[tempWindow.subviews count]; i++) {
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, add the button
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES)
[keyboard addSubview:doneButton];
} else {
if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
[keyboard addSubview:doneButton];
}
}
}
今の問題は、それがポートレートモードで正常に動作するということですが、私はテキストフィールドをクリックするとランドスケープモードでテキストフィールドがあることことをそんなにキーボードが表示され、表示がスクロールします編集した画像は画面に表示されなくなります。また、数字キーボード（Phone.appにあるようなもの）には、横向きモードのカスタム追加ボタンはありませんが、縦長モードのものがあります。
これを修正するにはどうすればよいですか？
