ios最完美的隐藏导航栏

使用代理隐藏当前控制器的导航栏    <UINavigationControllerDelegate>

self.navigationController.delegate = self;

//隐藏导航栏,将要显示控制器

- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController*)viewController animated:(BOOL)animated {

//判断要显示的控制器是否是自己

BOOL isShowHomePage = [viewController isKindOfClass:[self class]];

[self.navigationController  setNavigationBarHidden:isShowHomePage animated:YES];

}
