iOS中导航栏动态隐藏的其中一种方式

@interface Home_ViewController () <UINavigationControllerDelegate>

@end

@implementation Home_ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    //设置导航控制器的代理为self
    self.navigationController.delegate = self;
    
    
}


#pragma mark - UINavigationControllerDelegate
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    //判断要显示的控制器是否是自己的
    BOOL isShowHomePage = [viewController isKindOfClass:[self class]];
    [self.navigationController setNavigationBarHidden:isShowHomePage animated:YES];
}

• 设置self为导航控制器的代理,实现代理方法,在将要显示控制器中设置导航栏隐藏和显示,使用这种方式不仅完美切合滑动返回手势,同时也解决了切换tabBar的时候,导航栏动态隐藏的问题.
