問題：
用Interface Builder為UITabBarController 設(shè)置selected image仑濒，運行起來后提示：Could not load the "(null)" image referenced from a nib in the bundle with identifier
修改方法：
獲取制定的tabbar實例船逮，用代碼修改
<pre><code>
-
(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//storyboard每次都創(chuàng)建個新的實例對象墨吓，因此需要呈現(xiàn)它 否則不顯示
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"main" bundle:[NSBundle mainBundle]];
UITabBarController * tabBarController = [storyboard instantiateViewControllerWithIdentifier:@"TabBarController"];
self.window.rootViewController = tabBarController;NSArray *imageArray = @[@"ic_tabbar_home",@"ic_tabbar_oversea_red",@"ic_tabbar_faxian_red", @"ic_tabbar_shopping_cart", @"ic_tabbar_my"];
int i = 0;
NSArray *itemArray = tabBarController.tabBar.items;
for (UITabBarItem *item in itemArray) {
UIImage *image = [UIImage imageNamed:imageArray[i++]];
item.selectedImage = image;
}
tabBarController.tabBar.tintColor = [UIColor redColor];return YES;
}
</code></pre>
