ios之UITabBarItem显示真实自定义的图片而非颜色填充

让TabBarItem 显示出我们设置的图片的真实样子，需要看以下设置方法在AppDelegate.h中，拿到所有的item然后统一设置成自定义的图片分别是选中和未选中，针对ios7以后：

_tabBarController = [[UITabBarController alloc]init];

    [_tabBarController setViewControllers:@[recNav,feedNav,postNav,loginNav]];

    // 拿到 TabBar 在拿到想应的item

    UITabBar *tabBar = _tabBarController.tabBar;

    UITabBarItem *item0 = [tabBar.items objectAtIndex:0];

    UITabBarItem *item1 = [tabBar.items objectAtIndex:1];

    UITabBarItem *item2 = [tabBar.items objectAtIndex:2];

    UITabBarItem *item3 = [tabBar.items objectAtIndex:3];

    // 对item设置相应地图片

    item0.selectedImage = [[UIImage imageNamed:@"recognize-1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];;

    item0.image = [[UIImage imageNamed:@"recognize"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

     

    item1.selectedImage = [[UIImage imageNamed:@"life-1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];;

    item1.image = [[UIImage imageNamed:@"life"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

     

    item2.selectedImage = [[UIImage imageNamed:@"edit-1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];;

    item2.image = [[UIImage imageNamed:@"edit"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

     

    item3.selectedImage = [[UIImage imageNamed:@"setting-1"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];;

    item3.image = [[UIImage imageNamed:@"setting"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];




通过以上代码设置就把4个item的图片设置好了当然也可以分别在对应的controller中进行相应地设置，不过建议统一设置修改起来比较省事，如果需要在item点击有很炫的动画或是其他样式，那就需要高度自定义才能实现
