copied!<p>Jeff Hay was totally right in his comment except for one thing. You should do it in the <code>-viewDidAppear:</code> method of the view controller which originally presented the first modal view controller.</p> <p><strong>Example:</strong></p> <pre><code>// MyViewController.h @interface MyViewController : UIViewController { BOOL _shouldPresentSecondModalViewController; } @end </code></pre> <hr> <pre><code>// MyViewController.m @implementation MyViewController - (void)viewDidAppear:(BOOL)animated { if(_shouldPresentSecondModalViewController) { UINavigationController *myNavCon; // Code to create second modal navigation controller [self presentModalViewController:myNavCon animated:YES]; _shouldPresentSecondModalViewController = NO; } } - (void)presentFirstViewController { UINavigationController *myNavCon; // Code to create the first navigation controller _shouldPresentSecondModalViewController = YES; [self presentModalViewController:myNavCon animated:YES]; } @end </code></pre> <p><strong>EDIT:</strong><br> Now, if you want to pass data between the two modal view controllers, you can use a delegate.</p> <pre><code>// FirstModalViewControllerDelegate.h @protocol FirstModalViewControllerDelegate @optional - (void)controller:(FirstModalViewControllerDelegate *)vc shouldShowData:(id)anyType; @end </code></pre> <hr> <pre><code>// MyViewController.h @interface MyViewController : UIViewController <FirstModalViewControllerDelegate> { id _dataToDisplay; } @end </code></pre> <hr> <pre><code>// MyViewController.m @implementation MyViewController - (void)viewDidAppear:(BOOL)animated { if(_dataToDisplay != nil) { UINavigationController *myNavCon; // Code to create second modal navigation controller [self presentModalViewController:myNavCon animated:YES]; [_dataToDisplay release]; _dataToDisplay = nil; } } - (void)presentFirstViewController { UINavigationController *myNavCon; FirstModalViewController *myCon; // Code to create the first modal view controller [myCon setDelegate:self]; myNavCon = [[UINavigationController alloc] initWithRootViewController:myCon]; [self presentModalViewController:myNavCon animated:YES]; [myNavCon release]; } - (void)controller:(FirstModalViewControllerDelegate *)vc shouldShowData:(id)anyType { /* This method will get called if the first modal view controller wants to display some data. If the first modal view controller doesn't call this method, the _dataToDisplay instance variable will stay nil. However, in that case, you'll of course need to implement other methods to, like a response to a Done button, dismiss the modal view controller */ [self dismissModalViewController]; _dataToDisplay = [anyType retain]; } @end </code></pre>
