在应用程序的第二个视图中插入标签栏，标签栏包含5个以上的标签

Question

其他可添加6个标签的解决方案

对于超过5个标签我使用过CiExpandableTabBarController 问题是： 如果我添加CiExpandableTabBarController像这样： self.window.rootViewController = CiExpandableTabBarController; 那就没问题..

但我需要在第二个视图和视图之后添加它。 我的第一个视图是登录，所以首先，视图标签栏应该是可见的

现在我得到这样的输出：

未显示选定的tebbar项目图像

但我希望输出像这样：

我添加了这样的标签栏：

{

[self makeTabBar];

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
//==============


self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.

Answer 1

对于UITabBarItem的所选图像和未选择图像，它有两个属性，即finishedSelectedImage和finishedUnselectedImage。但是你根本无法设置这些属性，因为它们没有为它们定义任何setter方法，只有getter。

相反，你可以做这样的事情。假设'tab_1_unselImg'是未选中的标签图像，'tab_1_selImg'用于标签栏控制器第一个标签的选定标签。

[[[[self.tabBarController viewControllers] objectAtIndex:0] tabBarItem] 
setFinishedSelectedImage:tab_1_selImg withFinishedUnselectedImage:tab_1_unselImg];
