iOS TabbarController 设置底部Toolbar图片和文字颜色选中样式

提取公共方法：

-(void)createChildVcWithVc:(UIViewController *)vc Title:(NSString *)title image:(NSString *)image selectedImage:(NSString *)selectedImage
{
    
    //图片渲染
    vc.tabBarItem.title=title;
    vc.navigationItem.title=title;
    vc.tabBarItem.image=[UIImage imageNamed:image];
    vc.tabBarItem.selectedImage=[[UIImage imageNamed:selectedImage] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    
    //文字渲染
    NSMutableDictionary *dict=[NSMutableDictionary dictionary];
    dict[NSForegroundColorAttributeName]=[UIColor blackColor];
    [vc.tabBarItem setTitleTextAttributes:dict forState:UIControlStateNormal];
    
    //选中的文字渲染
    dict[NSForegroundColorAttributeName]=[UIColor orangeColor];
    [vc.tabBarItem setTitleTextAttributes:dict forState:UIControlStateSelected];
    
    YJNavigationController *nav=[[YJNavigationController alloc] initWithRootViewController:vc];
    [self addChildViewController:nav];
}

　　

使用方法：

 YJMeViewController *me=[[YJMeViewController alloc] init];
    [self createChildVcWithVc:me Title:@"我" image:@"tabbar_profile" selectedImage:@"tabbar_profile_selected"];
