通过单击UIAlertView确定按钮iPhone应用程序关闭了UITextView键盘？

Question

Am working in messaging based iPhone app. In one of my UIViewController i am showing UITextView keyboard and am getting some alert messages from webservice.

When i show the alert messages in UIAlertView, UITextview keyboard is dismissing by clicking OK button from UIAlertView. I have tried to put becomeFirstResponder in UIAlertView delegate but, still keyboard dismissing. For your reference,

-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
   [messageTextView becomeFirstResponder]; // Here again I am giving becomeFirstResponder to my UITextView

   int alertMessageArrayCount = [alertMessageArray count];
    if (messageAlertView) 
    {
        if (messageAlertCount < alertMessageArrayCount)  // These codes to show my all messages in UIAlertView one by one..
        {
            messageAlertCount = messageAlertCount + 1;

            arrayObjectValue = arrayObjectValue + 1;

            NSString *alertMessage = [alertMessageArray objectAtIndex:arrayObjectValue];

            messageAlertView = [[UIAlertView alloc] initWithTitle:@"Alert" message:alertMessage delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [messageAlertView show];
            [messageAlertView release];
        }
    }
}

Can anyone please help to solve this issue?

EDIT :

messageTextView = [[UITextView alloc] initWithFrame:CGRectMake(35, 5, 210, 30)];
messageTextView.delegate = self;
messageTextView.backgroundColor = [UIColor clearColor];
messageTextView.clipsToBounds = NO;
messageTextView.font = [UIFont fontWithName:@"Helvetica" size:14];
[self.view addSubView:messageTextView];

Answer 1

in your UIAlertView delegate method try like below insted of [messageTextView becomeFirstResponder];

if([messageTextView resignFirstResponder]){
    [messageTextView becomeFirstResponder];
    }

Answer 2

将alertview的委托写为“ nil”而不是self。

 messageAlertView = [[UIAlertView alloc] initWithTitle:@"Alert" message:alertMessage delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
