I am not sure how you do code, but here is my working code for this :
#pragma mark - Keyboard Notification
- (void)keyboardWillShow:(NSNotification *)notification {
NSDictionary *info = [notification userInfo];
NSValue *keyBoardEndFrame = [info objectForKey:UIKeyboardFrameEndUserInfoKey];
CGSize keyboardSize = [keyBoardEndFrame CGRectValue].size;
self.keyboardSize = keyboardSize;
}
- (void)keyboardWillHide:(NSNotification *)notification {
self.keyboardSize = CGSizeZero;
}
- (void) addToolBarToTextView {
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
toolBar.barStyle = UIBarStyleBlack;
toolBar.translucent = YES;
UIButton *doneBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[doneBtn setFrame:CGRectMake(0, 7, 65, 30)];
doneBtn.titleLabel.textAlignment = NSTextAlignmentCenter;
[doneBtn setTitle:@"Next" forState:UIControlStateNormal];
[doneBtn addTarget:self action:@selector(keyBoardDoneButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem * barItem = [[UIBarButtonItem alloc] initWithCustomView:doneBtn];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
toolBar.items = [NSArray arrayWithObjects: flexibleSpace, barItem, nil];
mobileTxtField.inputAccessoryView = toolBar;
}
-(void)viewDidLoad {
[super viewDidLoad];
[self addToolBarToTextView];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}
