Question

我的问题是我如何添加UITabBarController的childViewController的图标。我的代码是：

UITabBarController *tabBar=[[UITabBarController alloc]init];
MyUIViewController *mc=[[MyUIViewController alloc]init];
[tabBar addChildViewController:mc];
[self.navigationController pushViewController:tabBar animated:YES];

提前致谢。

请试试这个

UITabBarController *tabController = [[UITabBarController alloc] init];
SomeViewController *viewController = [[SomeViewController alloc] initWithNibName:@"SomeViewController" bundle:nil];
[tabController setViewControllers:[NSArray arrayWithObject:viewController]];//Setting child viewController Array.
UITabBarItem *item = (UITabBarItem *)[tabController.tabBar.items objectAtIndex:0]; //for first view
[item setImage:[UIImage imageNamed:@"someImage.png"]]; //Image should be 23px X 23px ,I think so.

我通过在MyUIViewController中添加属性和属性来解决这个问题：

@interface MyUIViewController{
    UITabBarItem *tabBarItem;
}
@property (nonatomic, retain) UITabBarItem *tabBarItem;

然后用图像初始化它：

UITabBarController *tabBar=[[UITabBarController alloc]init];
MyUIViewController *mc=[[MyUIViewController alloc]init];
mc.tabBarItem=[[UITabBarItem alloc] initWithTitle:@"MyTitle" image:[UIImage imageNamed:@"myImage.png"] tag:0];
[tabBar addChildViewController:mc];
[self.navigationController pushViewController:tabBar animated:YES];

我刚刚发现桌面不区分大小写，但设备要求代码具有相同的alpha-numberic大小写（上/下）。确保文件的名称相同......直到案例（上/下）！

示例：

“first.png”磁盘上的文件名最好表示为 - ＆gt; self.tabBarItem.image = [UIImage imageNamed：@“first”];

NOT - NOT --- NOT

self.tabBarItem.image = [UIImage imageNamed：@“First”];
