- 首页跳转下一页的时候，push前隐藏底下的tabBar
GWTeamInfoViewController *teamInfoVC = [[GWTeamInfoViewController alloc]initWithTeamId:teamId];
[teamInfoVC setHidesBottomBarWhenPushed:YES]; // 跳到下一页，隐藏底下的tabBar
[self.navigationController pushViewController:teamInfoVC animated:YES];
注意：侧滑返回上一页（在基类的viewDidAppear中设置YES可侧滑，在禁止侧滑的VC中的viewDidAppear方法中设置NO），如果tabbar那几个首页VC也是使用的基类VC设置侧滑的话，将他们单独设置interactivePopGestureRecognizer = NO，否则在其页面，侧滑之后，点击不了控件。
#pragma mark 视图已经加入到窗口时

NSLog(@"视图已经加入到窗口时");
// 是否允许右滑返回：YES 启动侧滑，NO 禁止侧滑

}
第一种：使用系统的导航栏
正式代码：
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
self.navigationController.navigationBar.backgroundColor = [UIColor whiteColor];
// 设置导航栏下边线（投影）去掉
self.navigationController.navigationBar.shadowImage = [[UIImage alloc] init];
// 设置导航栏背景图片
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@""] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];
[self.navigationController.navigationBar setTintColor:RGBA(0, 0, 0, 1)];
// 设置导航栏默认标题的颜色和字体的大小
self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName:RGBA(0, 0, 0, 1), NSFontAttributeName:[UIFont systemFontOfSize:([UIScreen mainScreen].bounds.size.width / 375)*18 weight:UIFontWeightMedium]};
/// iOS 13.0 之后的新特性：
NSDictionary *titleTextAttributes = @{NSForegroundColorAttributeName:RGBA(0, 0, 0, 1), NSFontAttributeName:[UIFont systemFontOfSize:([UIScreen mainScreen].bounds.size.width / 375)*18 weight:UIFontWeightMedium]};
if (@available(iOS 13.0, *)) {
UINavigationBarAppearance *appearance = [UINavigationBarAppearance new];
appearance.backgroundColor = [UIColor whiteColor]; // 导航栏背景颜色
appearance.titleTextAttributes = titleTextAttributes; // 设置导航栏默认标题的颜色和字体的大小
appearance.shadowColor = [UIColor clearColor]; // 设置导航栏底部的分割线不显示
self.navigationController.navigationBar.standardAppearance = appearance;
self.navigationController.navigationBar.scrollEdgeAppearance = appearance;
} else {
// Fallback on earlier versions
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
[self.navigationController.navigationBar setTitleTextAttributes:titleTextAttributes];
}
self.navigationController.navigationBarHidden = NO;
// 去掉导航栏上【返回】按钮 后面的文字
UIBarButtonItem *backButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
[self.navigationItem setBackBarButtonItem:backButtonItem];
// self.navigationController.navigationBar.topItem.title = @"";
UIButton *leftBut = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 23, 16)];
[leftBut setImage:[UIImage imageNamed:@"back_black_icon"] forState:UIControlStateNormal];
[leftBut addTarget:self action:@selector(clickBackLastPageAction) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBar = [[UIBarButtonItem alloc] initWithCustomView:leftBut];
self.navigationItem.leftBarButtonItem = backBar;
// self.navigationItem.leftItemsSupplementBackButton = NO; // 设置YES，以达到页面可以左滑的目的（但是会有系统"<"）
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self; // 自定义 按钮，并实现右滑返回效果（注意：如果不写“(id)”的话，就需要遵守代理UIGestureRecognizerDelegate）
self.edgesForExtendedLayout = UIRectEdgeNone; // self.view 的坐标在（0，导航栏高度+状态栏高度）
// self.navigationController.navigationBar.translucent = NO;
/**
// 禁止“右滑侧边”返回上一页
if (self.navigationController.interactivePopGestureRecognizer) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
*/
/*
// 替换系统的“<"图标
[self.navigationController.navigationBar setBackIndicatorImage:[UIImage imageNamed:@"back_black_icon"]];
[self.navigationController.navigationBar setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@"back_black_icon"]];
self.navigationItem.backBarButtonItem = backBar;
*/
/**
// 在有UIScrollview，并且是左右滑动的时候：以免侧滑失效，进行一下操作：
// 手势互斥(侧滑返回手势失效后才响应UITableView的滑动手势)
[self.myScrollView.panGestureRecognizer requireGestureRecognizerToFail:self.navigationController.interactivePopGestureRecognizer];
*/
}
- (void)clickBackLastPageAction {
[self.navigationController popViewControllerAnimated:YES];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)toRootViewController {
UIViewController *viewController = nil;
while (viewController.presentationController) {
// 判断是否为最底层控制器
if ([viewController isKindOfClass:[LRBaseViewController class]]) {
viewController = viewController.presentingViewController;
// self.navigationItem.title = @"";
} else {
break;
}
}
if (viewController) {
[viewController dismissViewControllerAnimated:YES completion:nil];
}
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
appDelegate.nowViewCTRL = self;
}
隐藏导航栏下边线：某一个页面中设置导航栏下边线的时候
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO animated:YES];
// 在该页面显示：
self.navigationController.navigationBar.shadowImage = [UIImage imageNamed:@""];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:YES];
// 退出该页面隐藏：
self.navigationController.navigationBar.shadowImage = [[UIImage alloc] init];
}
第二种：使用自定义的导航栏
（原理：将系统的导航栏隐藏，自定义一个UIView和其上边的按钮，即LeftButton和RightButton等等需要的按钮，和标题）
下面代码部分：
BaseViewController.h
