Installation 安装
CocoaPods - cocoaPods
If you're using CocoaPods, simply add pod 'RDVTabBarController' to your Podfile.
如果你使用了CocoaPods，简单的pod ‘RDVTabBarController’ 到你的Podfile文件中就行了。
Drag & Drop - 拖到项目当中
Add the items from RDVTabBarController directory to your project. If you don't have ARC enabled, you will need to set a -fobjc-arc compiler flag on the .m source files.
直接将RDVTabBarController文件夹拖到你的项目当中。如果你的项目是MRC的，你需要在.m文件里面设置-fobjc-arc编译标签。
Example Usage - 使用示例
Initialize RDVTabBarController
初始化RDVTabBarController
The initialization is similar to the one for UITabBarController. Create an instance of the tabBarController and initialize its viewControllers.
初始化方法与UITabBarController类似，创建一个tabBarController的实例以及初始化控制器。
UIViewController *firstViewController = [[RDVFirstViewController alloc] init];
UIViewController *firstNavigationController = [[UINavigationController alloc]
initWithRootViewController:firstViewController];
UIViewController *secondViewController = [[RDVSecondViewController alloc] init];
UIViewController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:secondViewController]; UIViewController *thirdViewController = [[RDVThirdViewController alloc] init]; UIViewController *thirdNavigationController = [[UINavigationController alloc] initWithRootViewController:thirdViewController]; RDVTabBarController *tabBarController = [[RDVTabBarController alloc] init]; [tabBarController setViewControllers:@[firstNavigationController, secondNavigationController, thirdNavigationController]]; self.viewController = tabBarController;
Customize RDVTabBarController - 定制RDVTabBarController
Each RDVTabBarItem has selectedBackground, unselectedBackground and corresponding properties for the icons: selectedImage and unselectedImage.
每一个RDVTabBarItem都有选择被背景与未选择的背景，或者是对应于选择的图片与未选择的图片。
UIImage *finishedImage = [UIImage imageNamed:@"tabbar_selected_background"];
UIImage *unfinishedImage = [UIImage imageNamed:@"tabbar_normal_background"]; NSArray *tabBarItemImages = @[@"first", @"second", @"third"]; RDVTabBar *tabBar = [tabBarController tabBar]; [tabBar setFrame:CGRectMake(CGRectGetMinX(tabBar.frame), CGRectGetMinY(tabBar.frame), CGRectGetWidth(tabBar.frame), 63)]; NSInteger index = 0; for (RDVTabBarItem *item in [[tabBarController tabBar] items]) { [item setBackgroundSelectedImage:finishedImage withUnselectedImage:unfinishedImage]; 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]; index++; }
Make the tab bar translucent - 可以让tab bar变得半透明
RDVTabBar has translucent property which determines how it is going to be handled.
RDVTabBar有着半透明色这个属性，他决定着怎么个透明方式。
RDVTabBar *tabBar = tabBarController.tabBar;
// After the tabBarController initialization
tabBar.translucent = YES;
// Customize the tabBar background
tabBar.backgroundView.backgroundColor = [UIColor colorWithRed:245/255.0 green:245/255.0 blue:245/255.0 alpha:0.9]]; // Inside the tabbed viewControllers - (void)viewDidLoad { [super viewDidLoad]; ... if (self.rdv_tabBarController.tabBar.translucent) { CGFloat tabBarHeight = CGRectGetHeight(self.rdv_tabBarController.tabBar.frame); UIEdgeInsets insets = UIEdgeInsetsMake(0, 0, tabBarHeight, 0); self.tableView.contentInset = insets; self.tableView.scrollIndicatorInsets = insets; } }
