TTPostController - Keyboard is not appearing - iphone

Question

Hi
I am adding a "post comment section in my iPhone APP"
rest all things are working fine but when I tap on "postController textView" a keyboard is suppose to appear from the bottom but it is not appearing However the cursor is displaying and the text that I am passing using postController.textView.text = #"" is also displaying.
Please suggest the areas to be looked for fixing this bug.
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
above is the code that is giving call to the Three20 PostController

Answer 1

below is the calling method which is unchanged...
-(IBAction)postComment:(id)sender
{
[UserManager instance]authenticateUserAndProceed:self withSelector:#selector(showCommentView)];
}
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
changed method
-(void)authenticateUserAndProceed:(id)parent withSelector:(SEL)selector
{
theParentViewController = parent;
self.theFunctionToCall = selector;
if(userid == nil)
{
GetUserInfoViewController *guivc = [[GetUserInfoViewController alloc] init];
[parent presentModalViewController:guivc animated:YES];
guivc.delegate = self;
[guivc release];
}
else {
//////////////////// below line was replaced///////////
// 2. [theParentViewController performSelector:selector];
// with below code
UIAlertView *alert =[[UIAlertView alloc]initWith Title........
[alert show];
}
}
PROBLEM SUMMARY:
as soon as the user registered, he was not able to the kyboard for the TTPostController
CHANGE SUMMARY:
As soon as the user is registered the call to
[theParentViewController performSelector:selector];
is not sent directly but the call goes to ann alertview which inter calls it.
EFETCS SUMMARY:
the user will see a "you are registered successfully" (kind of) alertview.
tapping OK on which, he will be sent to TTPostController. (this time the keyboard is appearing)
I kept the line# 2 in the AlertViewDelegate method.
I was amazed o see it working just by not calling the line 2 directly.
this worked for me.
I welcome any new and better idea to implement the same
