【问题描述】：
我的 iOS 应用出现问题。我用故事板和一些代码构建了我的应用程序。最初，我有一个 TableView，它在第一个选项卡中显示一些内容。现在我想把这个内容放在另一个标签中，但是当我编辑我的故事板时，我得到了这个错误：

这里是数组初始化的代码：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
_aircraft = [NSMutableArray arrayWithCapacity:20];
Aircraft *aircraft = [[Aircraft alloc] init];
aircraft.name = @"Robin DR400";
aircraft.immat = @"F-HAZA";
[_aircraft addObject:aircraft];
aircraft = [[Aircraft alloc] init];
aircraft.name = @"Tecnam P2002 JF";
aircraft.immat= @"F-HAZB";
[_aircraft addObject:aircraft];
aircraft = [[Aircraft alloc] init];
aircraft.name = @"Tecnam P2002 JF";
aircraft.immat= @"F-HAZC";
[_aircraft addObject:aircraft];
UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
UINavigationController *navigationController = [tabBarController viewControllers][0];
AircraftViewController *aircraftViewController = [navigationController viewControllers][0];
aircraftViewController.aircraft = _aircraft;
return YES;
}
【问题讨论】：
-
您尝试在
application:didFinishLaunchingWithOptions:中访问的数组之一为空 -
你分配和初始化你的数组了吗？您可以将代码发布在您创建数组的位置以及向其中添加项目的位置吗？
-
符号化崩溃报告，它会在您的
application:didFinishLaunchingWithOptions:方法中显示导致错误数组访问问题的确切行。 -
我已经编辑了帖子并添加了数组初始化的代码，谢谢！
-
该错误表明您访问索引
1，但您发布的代码没有引用索引1，只是0。再次对崩溃报告进行符号化，以便您确切知道是哪一行代码导致了问题。
