无法在键盘上隐藏完成栏

Question

我为文本字段分配了一个数字键盘。我不想在键盘上方或键盘内部显示任何已完成的按钮栏，但我无法隐藏该栏。

我正在尝试删除此栏：

我尝试做的是：

- (void)viewDidLoad {
    [super viewDidLoad];
    _txtAge.delegate=self;
    [_txtAge becomeFirstResponder];
    _txtAge.autocorrectionType = UITextAutocorrectionTypeNo;
}

- (void)textFieldDidBeginEditing:(UITextField*)textField
{
    UITextInputAssistantItem* item = [textField inputAssistantItem];
    item.leadingBarButtonGroups = @[];
    item.trailingBarButtonGroups = @[];
}

XCode 版本：9.3 (9E145)

Answer 1

试试这个：

_txtAge.inputAccessoryView = nil;

完整代码：

- (void)viewDidLoad {
    [super viewDidLoad];
    _txtAge.delegate=self;
    _txtAge.inputAccessoryView = nil;
    [_txtAge becomeFirstResponder];
    _txtAge.autocorrectionType = UITextAutocorrectionTypeNo;
}

// or try this

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {

  if (textField == _txtAge) {
    _txtAge.inputAccessoryView = nil;
  } 

  return true;
}

// or try this

- (void)textFieldDidBeginEditing:(UITextField *)textField {
  if (textField == _txtAge) {
    _txtAge.inputAccessoryView = nil;
  } 
}

Answer 2

- (void)textFieldDidBeginEditing:(UITextField*)textField{
   if (textField != self.yourTextField){
      UITextInputAssistantItem* item = [textField inputAssistantItem];
      item.leadingBarButtonGroups = @[];
      item.trailingBarButtonGroups = @[];
   }else{
      textField.inputAccessoryView = nil;
   }
}
