我是IOS开发的新手，我试图修改一个旧的应用程序。一切都在我的旧Mac（XCode 4.6）上运行，但是当我将它转移到我的新Macbook pro并使用最新版本的Xcode时，我在启动时遇到了这个错误：

这是我的main.h：

#import "AppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
经过一些搜索，很多关于.xib文件的所有者的修复，所以我将我的第一个窗口链接到视图，但它没有用...
我的xib文件所有者标签中的Printscreen： http://i.stack.imgur.com/iyzkk.png
我会继续照顾这个问题，但如果有人可以帮助我，那将是非常好的;）
感谢您的时间，
