    UITabBarItem *item2 = [tabBar.items objectAtIndex:];
    UITabBarItem *item3 = [tabBar.items objectAtIndex:];
    // 对item设置相应地图片
    item0.selectedImage = [[UIImage imageNamed:@"sy-1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];;
    item0.image = [[UIImage imageNamed:@"sy"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
