# LYTabBar
针对中间带有自定义按钮的tabbar,可以自定义中间按钮，调节中间按钮大小，调节上下偏移量，耦合性低，可移植性强
使用方法，详细用法及效果请移步wiki中：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    /**
     *  第一步：定义各个视图
     */
    FirstViewController *firstVC = [[FirstViewController alloc]init];
    firstVC.title = @"首页";
    SecondViewController    *secVC = [[SecondViewController alloc]init];
    secVC.title = @"个人";
    ThirdViewController *thirdVC = [[ThirdViewController alloc]init];
    thirdVC.title = @"第三";
    FourthViewController    *fourthVC = [[FourthViewController alloc]init];
    fourthVC.title = @"第四";
    
    /**
     *  第二部：添加各个视图数组、item图片数组、item选中后的图片数组
     */
    LYTabbarController  *tabbarController = [[LYTabbarController alloc]init];
    [tabbarController addChildViewControllers:@[firstVC,secVC,thirdVC,fourthVC] images:@[@"home",@"home",@"person",@"person"] selectedImages:@[@"home_selected",@"home_selected",@"person_selected",@"person_selected"]];
    /**
     *  第三部：设置中间按钮 不设置，默认尺寸（50，50），偏移量0.5居中显示
     */
    tabbarController.centerImage = [UIImage imageNamed:@"center"];  //设置按钮图片
    tabbarController.centerSelectedImage = [UIImage imageNamed:@"center_selected"]; //设置按钮高亮图片
    tabbarController.centerButtonOffset = 0.4;  //设置按钮的上下偏移量
    tabbarController.centerBounds = CGRectMake(0, 0, 60, 60);   //设置按钮尺寸
    tabbarController.centerButtonStyle = LYCenterButtonStyleBulge;  //设置tabbar的背景图片中间是否带有凸起，有凸起和不凸起两种背景图片，默认不凸起
    
    self.window.rootViewController = tabbarController;
    
    
    return YES;
}

中间按钮的实现可以写在LYTabbarController的- (void)tabBar:(LYBar *)tabBar DidClickCenterButton:(UIButton *)centerButton方法里
