status bar and Navigation bar problem after dismissed modal view

问题

the apps launched the mailcomposer modal view (MFMailComposeViewController) when the Contact Us button is pressed. but once the modal view is loaded, the status bar is hidden automatically.

I setStatusBarHidden Status to NO after modal view controller is dismissed.

[self dismissModalViewControllerAnimated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:NO];

but the status bar and navigation bar is overlapped after ModalViewController is dismissed.

I got no clue how to fix it. Appreciate any kind help. Thanks.

回答1:

my problem is solved by launching the MFMailComposeViewController from appDelegate tabBarController

 myAppDelegate *mDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate];
[mDelegate.tabBarController presentModalViewController:picker animated:YES];

instead of launching from the navigation Controller

[self presentModalViewController:picker animated:YES];
