RDVTabBarController：一个十分完善的tabBarController，可以自定义角标个数，爽的停不下来。

说明

此教程是旨在让你快速入手，如需更加深层次的了解，请直接RDVTabBarController地址分析即可；

使用

pod 'RDVTabBarController'

结构

RDVTabBar @interface RDVTabBar : UIView RDVTabBarController @interface RDVTabBarController : UIViewController RDVTabBarItem @interface RDVTabBarItem : UIControl

RDVTabBarController Example Usage其实已经很详细了，接下来看初始化

//VString宏定义，为了就是更好的国际化语言，适配多语言，刚好此Demo也国际化了，可以参看https://github.com/sauchye/dev_notes/issues/4 #define VString(x) NSLocalizedString(x, nil) - (void)setupViewControllers{ SYFirstViewController *firstVC = [[SYFirstViewController alloc] init]; SYSecondViewController *secondVC = [[SYSecondViewController alloc] init]; SYThirdViewController *thirdVC = [[SYThirdViewController alloc] init]; firstVC.title = VString(@"Home"); secondVC.title = VString(@"Found"); thirdVC.title = VString(@"Me"); self.firstNav = [[SYBaseNavigationController alloc] initWithRootViewController:firstVC]; self.secondNav = [[SYBaseNavigationController alloc] initWithRootViewController:secondVC]; self.thirdNav = [[SYBaseNavigationController alloc] initWithRootViewController:thirdVC]; [self setViewControllers:@[self.firstNav, self.secondNav, self.thirdNav]]; [self customizeTabBarForController]; } NSInteger index = 0; for (RDVTabBarItem *item in [[self tabBar] items]) { item.titlePositionAdjustment = UIOffsetMake(0, 2.0); [item setBackgroundSelectedImage:backgroundImage withUnselectedImage:backgroundImage]; UIImage *selectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_selected",[tabBarItemImages objectAtIndex:index]]]; UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_normal",[tabBarItemImages objectAtIndex:index]]]; [item setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage]; [item setTitle:[tabBarItemTitles objectAtIndex:index]]; item.selectedTitleAttributes = @{ NSFontAttributeName: [UIFont boldSystemFontOfSize:12], NSForegroundColorAttributeName:kNAVIGATION_BAR_COLOR, }; item.unselectedTitleAttributes = @{ NSFontAttributeName: [UIFont boldSystemFontOfSize:12], NSForegroundColorAttributeName:RGB(217, 217, 217), }; [item setTitle:[tabBarItemTitles objectAtIndex:index]]; index++; } }

这样你的tabBar基本搭建好了，但是还需要完善一些，比如，角标设置，push隐藏等。

Push隐藏tabBar，你只需要这样即可 - (void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [[self rdv_tabBarController] setTabBarHidden:YES animated:YES]; } 设置角标数 [[self rdv_tabBarItem] setBadgeValue:@"3"]; RDVTabBarControllerDelegate，相信你看就会明白，好的方法命名很重要啊~ /** * Asks the delegate whether the specified view controller should be made active. */ - (BOOL)tabBarController:(RDVTabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController; /** * Tells the delegate that the user selected an item in the tab bar. */ * (void)tabBarController:(RDVTabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController;

结语

RDVTabBarController是一个很棒的第三方tabBarController，值得我们学习和思考。

相比传统第三方，你会发现可以很好的定制角标，这是极好的，当然你也可以自定义； 但是不能定义中间凸起的tabBar，好早之前去哪儿就是中间凸起一个tabBar，不过现在去哪儿也改成传统的tabBar了；
