Добавить UISearchBar выше клавиатуры

Question

Я хочу, чтобы отобразить панель поиска над клавиатурой. Всякий раз, когда появляется клавиатура, панель поиска также должна появляться. Как это сделать?

Answer 1

Создайте объект UISearch панели и добавить наблюдателя для клавиатуры в textFieldDidBeginEditing/textViewDidBeginEditing

- (void)textViewDidBeginEditing:(UITextView *)textView 
{ 
    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(keyboardWasShown:) 
               name:UIKeyboardDidShowNotification 
               object:nil]; 
} 

- (void)keyboardWasShown:(NSNotification *)notification 
{ 

CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size; 

int height = MIN(keyboardSize.height,keyboardSize.width); 
int width = MAX(keyboardSize.height,keyboardSize.width); 

//set frame for searchbar 
    searchBar.frame = CGRectMake(0, self.view.frame.size.height - height, width, 50);  
    } 

Answer 2

- (void)viewWillAppear:(BOOL)animated { 
    [super viewWillAppear:animated]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil]; 
} 

- (void)viewWillDisappear:(BOOL)animated { 
    [super viewWillDisappear:animated]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil]; 
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil]; 
} 

- (void)keyboardWillShow:(NSNotification *)notification 
{ 
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size; 

    [UIView animateWithDuration:0.3 animations:^{ 
     CGRect f = self.view.frame; 
     f.origin.y = -keyboardSize.height; 
     self.view.frame = f; 
    }]; 
} 

-(void)keyboardWillHide:(NSNotification *)notification 
{ 
    [UIView animateWithDuration:0.3 animations:^{ 
     CGRect f = self.view.frame; 
     f.origin.y = 0.0f; 
     self.view.frame = f; 
    }]; 
}

Вы можете просто использовать textField.inputAccessoryView = поиска бар

textField.inputAccessoryView = mySearchBar;
