我的 iPhone 应用程序中有两个UITextView。当用户选择一个UITextView控制器自动转到另一个UITextView。我在我的项目中尝试了以下方式。但是第二个UITextView直到becomefirstresponder用户在第二个里面点击才会出现UITextView。

 -(void) viewDidLoad
{   
    TextView1 = [[UITextView alloc] initWithFrame:CGRectMake(10, 320, 300, 50)];
    TextView1.delegate = self;
    TextView1.backgroundColor = [UIColor clearColor];
    TextView1.layer.borderWidth = 2;
    TextView1.layer.borderColor = [UIColor blackColor].CGColor;
    TextView1.layer.cornerRadius = 5;
    [self.view addSubview: TextView1];

    TextView2 = [[UITextView alloc] initWithFrame:CGRectMake(10, 5, 300, 30)];
    TextView2.delegate = self;
    TextView2.backgroundColor = [UIColor whiteColor];
    TextView2.layer.borderWidth = 2;
    TextView2.layer.borderColor = [UIColor lightTextColor].CGColor;
    TextView2.layer.cornerRadius = 5;
    [self.view addSubview: TextView2];

    UIBarButtonItem *textBarButton = [[UIBarButtonItem alloc] initWithCustomView: TextView2];

    accessoryToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    accessoryToolBar.items = [NSArray arrayWithObjects:textBarButton, nil];
}

 -(BOOL) textViewShouldBeginEditing:(UITextView *)textView
{
    NSLog(@"TextView Should Begin Editing");
    if (textView == messageTextView) 
    {
        [TextView2 setInputAccessoryView:accessoryToolBar];
        [TextView1 resignFirstResponder];
        [TextView2 becomeFirstResponder];
    }
    else
    {
        [TextView2 setInputAccessoryView:accessoryToolBar];
        [TextView1 resignFirstResponder];
    }

    return YES;
}

我怎样才能解决这个问题？

删除完整的textViewShouldBeginEditing方法。那是错误的观点。

您希望，当用户触摸第一个 textView 时，应该选择第二个，对吧？如果那是您想要的，请textViewDidBeginEditing:改用。

- (void) textViewDidBeginEditing:(UITextView *)textView
{
  if(textView == TextView1) {
    [TextView2 becomeFirstResponder];
  }
}

这应该是你需要的一切。
