Flip navigation controller

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: 1];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:YES];
[self.navigationController pushViewController:atab animated:YES];
//[self.navigationController pushViewController:myViewController animated:NO];
[UIView commitAnimations];

change navigation bar to black

self.navigationController.navigationBar.barStyle = UIBarStyleBlack;

remove charcater from string

lets say you have @"hello" now ir order to get ello you can do this
NSString *newStr = [myString substringWithRange:NSMakeRange(1, [myString length] - 1)];
