先看一下效果

1.首先创建一个新工程，结构是TabbarViewController+UIViewController*4

@interface AppDelegate ()<UITabBarControllerDelegate>{    UITabBarController                  *tabBarController;    NSMutableArray                      *isInArray;         // 标记动画方向    UIViewController                    *controller;        //一个全局VC}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {        //    //初始化window设置其背景图    //    self.window = [[UIWindow alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH_NEW, SCREEN_HEIGHT_NEW)];    UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"b%d",5]]];    imageView.frame = self.window.frame;    [self.window addSubview:imageView];        //    //array：存放4个透明VC（为了正常显示系统的TabBar和其点击事件）。第一个VC默认设置微信截图    //    NSMutableArray *array = [[NSMutableArray alloc]initWithCapacity:4];        NSArray *titleArray = @[@"微信",@"通讯录",@"发现",@"我"];        for(int i = 0 ; i < 4 ; i ++){        UIViewController *controller_ = [[UIViewController alloc]init];        [array addObject:controller_];                UITabBarItem *item = [[UITabBarItem alloc]initWithTitle:titleArray[i] image:[UIImage imageNamed:[NSString stringWithFormat:@"%d",i+1]] tag:i];        controller_.tabBarItem = item;                if (i == 0) {            UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"b%d",i+1]]];            imageView.frame = self.window.frame;            [controller_.view addSubview:imageView];                    }    }            tabBarController = [[UITabBarController alloc]init];        tabBarController.viewControllers = array;        tabBarController.delegate = self;        self.window.rootViewController = tabBarController;    [self.window makeKeyAndVisible];            //    //全局VC，展示不同截图    //    controller = [[UIViewController alloc]init];                //    //动画方向    //    isInArray = @[[NSNumber numberWithBool:NO],                  [NSNumber numberWithBool:YES],                  [NSNumber numberWithBool:YES],                  [NSNumber numberWithBool:YES]].mutableCopy;        return YES;}

2 实现UITabBarControllerDelegate

-(void)tabBarController:(UITabBarController *)tabBarControllerLocal didSelectViewController:(UIViewController *)viewController{        NSLog(@"%lu",(unsigned long)tabBarController.selectedIndex);        //    //tabBarItem点击后 就把默认图移除    //    [tabBarController.viewControllers[0].view removeAllSubviews];        //    //设置对应截图    //    UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"b%lu",tabBarController.selectedIndex+1]]];    imageView.frame = self.window.frame;    [controller.view addSubview:imageView];        [tabBarController.view insertSubview:controller.view belowSubview:tabBarController.tabBar];        //    //开始动画    //    [self genieToRect:CGRectMake(0, 0, 0, 0) edge:BCRectEdgeTop ];        }

3 实现动画方法。从github上下载UIView+Genie这个开源代码，然后引入UIView+Genie。地址https://github.com/Ciechan/BCGenieEffect/

- (void) genieToRect: ( CGRect)rect2 edge: (BCRectEdge) edge{        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{        //        //isin = NO执行的是向下回收的动画  一个页面下来 其他的应该都下去        //                //        //不同的起始位置        //        CGRect rect = CGRectMake(SCREEN_WIDTH_NEW/4* tabBarController.selectedIndex, SCREEN_HEIGHT_NEW +100, SCREEN_WIDTH_NEW / 5, 20);                UIView *tranView = controller.view;                BOOL isin = [isInArray[tabBarController.selectedIndex] boolValue];                if (isin  == NO) {            //            //向下            //            for (int i = 0; i < isInArray.count; i ++) {                if (i != tabBarController.selectedIndex) {                                        [isInArray replaceObjectAtIndex:i withObject:[NSNumber numberWithBool:YES]];                                        tabBarController.viewControllers[i].view.frame = CGRectMake(SCREEN_WIDTH_NEW/4* i, SCREEN_HEIGHT_NEW +20, SCREEN_WIDTH_NEW/5, 20);;                }            }        }else{            //            //向上            //            for (int i = 0; i < isInArray.count; i ++) {                if (i != tabBarController.selectedIndex) {                                       [isInArray replaceObjectAtIndex:i withObject:[NSNumber numberWithBool:YES]];                                        tabBarController.viewControllers[i].view.frame = CGRectMake(SCREEN_WIDTH_NEW/4* i, SCREEN_HEIGHT_NEW +20, SCREEN_WIDTH_NEW/5, 20);;                                    }            }                    }        NSTimeInterval duration = 0.5;                tabBarController.tabBar.userInteractionEnabled = NO;                CGRect endRect = rect;                if (isin) {                        [tranView genieOutTransitionWithDuration:duration startRect:endRect startEdge:edge completion:^{                                BOOL isInLocal = [isInArray[tabBarController.selectedIndex] boolValue];                                [isInArray replaceObjectAtIndex:tabBarController.selectedIndex withObject:[NSNumber numberWithBool:!isInLocal]];                                tabBarController.tabBar.userInteractionEnabled = YES;                            }];        } else {            NSLog(@"xia");            [tranView genieInTransitionWithDuration:duration destinationRect:endRect destinationEdge:edge completion:             ^{                 BOOL isInLocal = [isInArray[tabBarController.selectedIndex] boolValue];                                  [isInArray replaceObjectAtIndex:tabBarController.selectedIndex withObject:[NSNumber numberWithBool:!isInLocal]];                                  tabBarController.tabBar.userInteractionEnabled = YES;                              }];                                }    });}
