Error when attempting to set custom animation for the viewController transition iOS4
objective-c, uinavigationcontroller, uiviewanimationtransition
Solution
Hey I got the same exception when my custom containment view controller was a subclass of UINavigationViewController. When I made my containment vc a subclass of UIViewController it worked like a charm. Your problem might be different. From the apple docs:
This method is only intended to be called by an implementation of a custom container view controller. If you override this method, you must call super in your implementation.
You are calling this method on a UINavigationViewController instance, not on an instance of a custom container view controller.
Problem
I am building an iPhone app and I have implemented a section for knowledge base about the app's subject matter. I used a table view and navigation viewController so that upon selecting any cell in the table a new view controller will be created and added on to the navigation stack. I tried to implement the curl up/ down animation myself but i get this error at runtime Parent view controller is using legacy containment in call to -[UIViewController transitionFromViewController:toViewController:duration:options:animations:completion:]' here is the code sample ``` (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ // change the accessory button to activity indicator UITableViewCell *cell = [mTableView cellForRowAtIndexPath:indexPath]; SomeViewController *ad = [[SomeViewController alloc] initWithNibName:@"SomeViewController" bundle:[NSBundle mainBundle]]; ad.title = cell.textLabel.text; [self.navigationController addChildViewController:ad]; [self.navigationController transitionFromViewController:self toViewController:ad duration:0.7 options:UIViewAnimationOptionTransitionCurlUp animations:^{} completion:^(BOOL completed){ [ad release]; }]; ``` Any help, advice and tips is very much appreciated! Thanks!
