1.设置全局导航backButton标题为nil or 自定义标题
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(NSIntegerMin, NSIntegerMin) forBarMetrics:UIBarMetricsDefault];
UIBarButtonItem *returnButtonItem = [[UIBarButtonItem alloc] init];
returnButtonItem.title = @"返回";
self.navigationItem.backBarButtonItem=returnButtonItem;
2.设置导航返回按钮隐藏
[self.navigationItem setHidesBackButton:YES];
3.设置导航栏原点坐标
self.navigationController.navigationBar.translucent = NO;
4.设置文字颜色
self.tabBar.tintColor = [UIColor yellowColor];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor greenColor],NSForegroundColorAttributeName, nil] forState:UIControlStateSelected];
5.设置图片不被渲染
[[UIImage imageNamed:@""] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
6.使用系统自带UITabbarController方法：
- (void)setupChildViewController:(UIViewController *)childVC
title:(NSString *)title
imageName:(NSString *)imageName
selectedImageName:(NSString *)selectedImageName
tabBar:(UITabBar *)tabBar
index:(NSUInteger)index {
childVC.title = title;
UITabBarItem *item = [tabBar.items objectAtIndex:index];
UIImage *image = [UIImage imageNamed:imageName];
UIImage *selectedImage = [UIImage imageNamed:selectedImageName];
// 设置不对图片进行蓝色的渲染
[item setImage:[image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
[item setSelectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
}
7.使用导航代理方法隐藏二三级视图的UITabbar<UINavigationControllerDelegate>
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
NSInteger subviewCount=navigationController.viewControllers.count;
if (subviewCount > 1) {
self.tabBar.hidden = YES;//自定义的视图，使用_customTabbarView.hidden = YES;
}
if (subviewCount == 1) {
self.tabBar.hidden = NO;//_customTabbarView.hidden = NO;
}
}
