一.使用方法

/**
 根据 传入参数 设置 自定义 tabbarController

@param viewControllerArray viewController 字符串 数组
 @param imageNameArray 普通 图片 数组
 @param selectedImageNameArray 选中 图片 数组
@param titleArray tabbarItem 标题
@return tabbarController
*/

- (instancetype)initWithViewControllerArray:(NSArray<NSString *> *)viewControllerArray
                         imageNameArray:(NSArray<NSString *> *)imageNameArray
                 selectedImageNameArray:(NSArray<NSString *> *)selectedImageNameArray
                             titleArray:(NSArray<NSString *> *)titleArray;

二.举个🌰 ：

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

        self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

         NSArray *viewControllerArray = [NSArray arrayWithObjects:

                                @"FJCourseViewController",

                                @"FJDiscoverViewController",

                                @"FJShopViewController",

                                @"FJProfileViewController",

                                nil];



         NSArray *imageNameArray = [NSArray arrayWithObjects:

                                 @"tab_jingxuan_hui.png",

                                 @"tab_faxian_hui.png",

                                @"tab_dianpu_hui.png",

                                 @"tab_wode_hui.png",

                                 nil];



         NSArray *selectedImageNameArray = [NSArray arrayWithObjects:

                                        @"tab_jingxuan_xuanzhong.png",

                                        @"tab_faxian_xuanzhong.png",

                                           @"tab_dianpu_xuanzhong.png",

                                         @"tab_wode_xuanzhong.png",

                                          nil];



         NSArray *titleArray = [NSArray arrayWithObjects:

                             @"精选",

                            @"发现",
    
                             @"店铺",

                               @"我的",

                             nil];



        self.window.rootViewController = [[FJTabbarViewController alloc] initWithViewControllerArray:viewControllerArray imageNameArray:imageNameArray selectedImageNameArray:selectedImageNameArray titleArray:titleArray];



         self.window.backgroundColor = [UIColor whiteColor];

         [self.window makeKeyAndVisible];

         return YES;
      }
