该页面需要隐藏导航栏,你可能会这么设置

- (void)viewWillAppear:(BOOL)animated {

[super viewWillAppear:animated];

self.navigationController.navigationBarHidden = YES;

}

- (void)viewWillDisappear:(BOOL)animated {

[super viewWillDisappear:animated];

self.navigationController.navigationBarHidden = NO;

}

然而如此设置之后,push到下一个页面,再滑动返回的时候,会出现黑色不平话界面出现

正确的设置方法是

- (void)viewWillAppear:(BOOL)animated {

[super viewWillAppear:animated];

[self.navigationController setNavigationBarHidden:YES animated:animated];//开启动画效果

}

- (void)viewWillDisappear:(BOOL)animated {

[super viewWillDisappear:animated];

[self.navigationController setNavigationBarHidden:NO animated:animated];//开启动画效果

}
