UITabBarController *tabBarController =
(UITabBarController *)self.window.rootViewController;
UINavigationController *navigationController =
[[tabBarController viewControllers] objectAtIndex:0];
PlayerViewController *playerViewController =
[[navigationController viewControllers] objectAtIndex:0];
playerViewController.players = players;
return YES;
用的Stroryboard
TabBar->Nav(包含TableView)
照着示例写的，可是运行报错。
报错：iphone program received signal:"SIGABRT"
位置：
PlayerViewController *playerViewController =
[[navigationController viewControllers] objectAtIndex:0];
------解决方案--------------------
看下[navigationController viewControllers] 返回的NSArray 中的object数量是不是0 或者是nil
