IOS正确解决隐藏导航栏后push、pop闪黑问题

@interface WLHomePageController () 
 
@end
 
@implementation WLHomePageController 
 
#pragma mark - lifeCycle
- (void)viewDidLoad {
    [super viewDidLoad];
 
    // 设置导航控制器的代理为self
    self.navigationController.delegate = self;
}
 
#pragma mark - UINavigationControllerDelegate
// 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];
}
