ios - Tabbar 项目图像不显示

Question

我对标签栏项目的图像有疑问。我在每个标签栏项目上设置了一个图像，但是当我运行该应用程序时，唯一出现的图像是第一个标签栏项目的图像。在我选择这些选项卡之一之前，其他选项卡栏项目的图像不会出现。我用来在标签栏项目上设置图像的代码如下:

[self.tabBarItem setImage:[UIImage imageNamed:@"multi30x30.png"]];

[self.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"multi30x30.png"]
              withFinishedUnselectedImage:[UIImage imageNamed:@"multi30x30.png"]];

有人可以帮助我吗？

你可以试试这个:

[[[self.tabBarController.viewControllers objectAtIndex:0] tabBarItem]setFinishedSelectedImage:[UIImage imageNamed:@"LocateIconActive.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"LocateIconInactive.png"]];

[[[self.tabBarController.viewControllers objectAtIndex:1] tabBarItem]setFinishedSelectedImage:[UIImage imageNamed:@"ProductsIconActive.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"ProductsIconInactive.png"]];

[[[self.tabBarController.viewControllers objectAtIndex:2] tabBarItem]setFinishedSelectedImage:[UIImage imageNamed:@"NextDeliveryIconActive.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"NextDeliveryIconInactive.png"]];
