Question

我在iOS 5中有一个标签，并且希望为所选和未选择的状态设置TabBarButton的图像。这是代码：

 BOOL isIOS5 = [[[UIDevice currentDevice] systemVersion] floatValue] >= 5.0;

    if(isIOS5)
    {
        //[tabBarController.tabBar setBackgroundImage:[UIImage imageNamed:@"Tab-bg"]];
       // [tabBarController.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"Cell-bg"]];

         [[tabBarController.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"list-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"list-menu"]];
        [[tabBarController.tabBar.items objectAtIndex:1] setFinishedSelectedImage:[UIImage imageNamed:@"gallery-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"gallery-menu"]];
        [[tabBarController.tabBar.items objectAtIndex:2] setFinishedSelectedImage:[UIImage imageNamed:@"map-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"map-menu"]];
        [[tabBarController.tabBar.items objectAtIndex:3] setFinishedSelectedImage:[UIImage imageNamed:@"submit-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"submit-menu"]];
        [[tabBarController.tabBar.items objectAtIndex:4] setFinishedSelectedImage:[UIImage imageNamed:@"search-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"search-menu"]];
    }

即。对于非视网膜显示，图像的高度为44px，因此它们应足以填充空间

问题是图像不能从上到下：在标签栏的底部还有一些未填充的空间。有没有人遇到过这个问题？

Answer 2

如果您已经在检查iOS 5等特定情况，那么最简单的方法就是创建与条形码的精确像素高度相匹配的图像。或者，您可以查看tabBar.item本身可以设置的属性。

无法自定义iOS5中的标签栏
