隐藏顶部导航栏

-(void)viewWillAppear:(BOOL)animated {

[super viewWillAppear:animated];

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

}

-(void)viewWillDisappear:(BOOL)animated {

[super viewWillDisappear:animated];

[self.navigationController setNavigationBarHidden:NO animated:YES];

}

设置背景图

self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"001"]];

进入界面时隐藏底部tabbar

// 进入某个界面

NextViewController *nextVC = [[TypeSupplierViewController alloc] init];

// 根据点击种类不同，设立种类属性

nextVC.hidesBottomBarWhenPushed=YES;

// 进入后隐藏tabbar

[self.navigationController pushViewController:nextVC animated:YES];

// 退出时显示tabbar

self.hidesBottomBarWhenPushed = NO;

平常隐藏

self.tabBarController.tabBar.hidden = YES;
