Answer 1

J'ai utilisé ce code pour mon projet, je pense que ce n'est pas optimisé mais il fonctionne très bien.

.h

BOOL firstTime; 
BOOL add; 
BOOL keyboardOpened; 

.m

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    firstTime = TRUE; 
    add = TRUE; 

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil]; 
} 

- (void)addButtonToKeyboard { 
    // create custom button 
    UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    doneButton.frame = CGRectMake(0, 163, 106, 53); 
    doneButton.adjustsImageWhenHighlighted = NO; 
    [doneButton setImage:[UIImage imageNamed:@"DoneUp3.png"] forState:UIControlStateNormal]; 
    [doneButton setImage:[UIImage imageNamed:@"DoneDown3.png"] forState:UIControlStateHighlighted]; 
    doneButton.tag = 3; 
    [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 ([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES && add) [keyboard addSubview:doneButton]; 
    } 
} 

- (void)removeButtonFromKeyboard 
{ 
    // 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, remove the button 
     if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES) [[keyboard viewWithTag:3] removeFromSuperview]; 
    } 
} 

- (void)doneButton:(id)sender { 
    [firstResponder resignFirstResponder]; 
    if (![[[UIDevice currentDevice] model] isEqualToString:@"iPad"] && ![[[UIDevice currentDevice] model] isEqualToString:@"iPad Simulator"]) 
    { 
     [self removeButtonFromKeyboard]; 
     firstTime = TRUE;

      break; 
     } 
    } 

    if (![[[UIDevice currentDevice] model] isEqualToString:@"iPad"] && ![[[UIDevice currentDevice] model] isEqualToString:@"iPad Simulator"]) 
    {
