Put this code in the view controller you want to hide the navigation bar for.
将此代码放在要为其隐藏导航栏的视图控制器中。
- (void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}
And you may also want to stick this in there, depending on your needs:
你可能还想把它放在那里，这取决于你的需要：
- (void) viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];
}

Here's how to do it in Swift 3:
以下是如何在Swift 3 中执行此操作：
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.setNavigationBarHidden(true, animated: animated)
}
P.S. I found that if you set animated to false, a black bar appears on push. But when it is set to trueit's smooth as silk!
PS我发现如果您将动画设置为false，则推送时会出现黑条。但是当它被设置时它true像丝绸一样光滑！

For iOS 8 May be this work around could work it
对于 iOS 8 可能是这个工作可以解决
CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController setNavigationBarHidden:TRUE animated:FALSE];
[self.navigationController pushViewController:productViewObj animated:FALSE];
[productViewObj.navigationController setNavigationBarHidden:TRUE animated:FALSE];
[productViewObj release];
