今天早上我的应用程序工作正常。我更新到Xcode 5.1，当我运行我的应用程序时，它在我玩游戏时崩溃了。我的应用程序有一个模式按钮，通向另一个视图控制器。第一个视图控制器是主屏幕。我启动应用程序，按下播放按钮，然后大约一秒钟没有做任何事情（而不是带我到第二个视图控制器，这是游戏本身），然后Xcode将我带到main.m.这是我的main.m看起来像（没有修改它）。因此，当Xcode将我带到此处时，以return UIApplicationMain开头的行以绿色突出显示，而在最右侧则显示主题1：信号SIGABRT
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
int main(int argc, char * argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
有没有人对发生的事情有什么建议？
------更新
我不确定这是否有帮助（因为我还是初学者，但我认为就是这样）。它说：

这是更新的问题，视图已加载
答案 0 :(得分：4)
好的，在您的应用中的某个位置，您尝试从网址加载文件，但网址为零。
您能否显示执行此操作的代码？它将有助于回答你的问题。
实际上，它位于Game.m方法的- (void)viewDidLoad;文件中。
