Question

I have a subclass of TTMessageController that shows … BUT it is not animated even though it should be. The code that displays the modal view looks like this (where PostToWebMessageController is the subclass of TTMessageController:

if (self.toWebMsgController == nil) {
    self.toWebMsgController = [[PostToWebMessageController alloc] init];
}

UINavigationController *navController = [[UINavigationController alloc] init];
[navController pushViewController:self.toWebMsgController animated:NO];

[self presentModalViewController:navController animated:YES];

What happens though is this: The screen goes black … the keyboard scrolls up into view … and THEN the TTMessageController view shows up (not animated). When I dismiss the view via a Cancel button the screen goes black and then just disappears (no animation again).

Any ideas why this is happening? I’ve this with a number of other TT* controllers and I can’t get one to animate right with showing modally.

Thanks

UPDATE:

This is happening in EVERY UIViewController that I try to present modally. Screen goes black, keyboard animates upwards and then view displays. Any ideas why this might be happening???

A day to figure this out … hopefully someone will benefit from my pains!

Here is what is happening:

The UIViewController calling presentModalViewController is itself nested inside a UIScrollView that is contained in ANOTHER UIViewController. Apparently, cocoa touch doesn’t much like this. Anyhow, to rectify the problem I did the following:

1. Add a property of type UIViewController to the UIViewController that will present a modal view controller (e.g. @property (nonatomic, retain) UIViewController *owningController;)

2. Set that property = to the topmost UIViewController (the one that contains the UIScrollView in this case)

3. In the UIViewController that shows the modal view … change this

[self presentModalViewController:controller animated:YES];

to this …

[owningController presentModalViewController:controller animated:YES];
