說明

此教程是旨在讓你快速入手，如需更加深層次的瞭解，請直接RDVTabBarController地址分析便可；

使用

pod 'RDVTabBarController'

建議直接CocoaPods管理，對CocoaPods有興趣的童鞋能夠戳<a href="http://code4app.com/article/cocoapods-install-usage">cocoapods-install-usage</a>html

結構

RDVTabBar 
@interface RDVTabBar : UIView

RDVTabBarController
@interface RDVTabBarController : UIViewController

RDVTabBarItem
@interface RDVTabBarItem : UIControl

RDVTabBarController Example Usage其實已經很詳細了，接下來看初始化ios

//VString宏定義，爲了就是更好的國際化語言，適配多語言，恰好此Demo也國際化了，能夠參看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];
}

- (void)customizeTabBarForController{

    //tabbar 背景圖片 tabbar_background
    UIImage *backgroundImage = [UIImage imageNamed:@"tabbar_background"];
    //選項卡圖片
    NSArray *tabBarItemImages;
  	//這裏添加tabBar icon圖片
    //= @[VString(@"First"), VString(@"Second"),VString(@"Third")];

    NSArray *tabBarItemTitles = @[VString(@"Home"), VString(@"Found"), VString(@"Me")];
    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++;

    }
}

這樣你的tabBar基本搭建好了，可是還須要完善一些，好比，角標設置，push隱藏等。

Push隱藏tabBar，你只須要這樣便可git

- (void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [[self rdv_tabBarController] setTabBarHidden:YES animated:YES];
}

設置角標數github

[[self rdv_tabBarItem] setBadgeValue:@"3"];

RDVTabBarControllerDelegate，相信你看就會明白，好的方法命名很重要啊~objective-c

/**
 * 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;
