xcode 4.02美好的一天 - 当我试图将我的项目（从 mac os x 6）传输到（mac os x lion）时已经过去了几天xcode 4.3所以它完全失败（（问题是 [Apple Mach-o Linker id Error]
当我添加问题开始
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
//This one BaseView* testView = [[BaseView alloc] initWithFrame:CGRectMake(0.0f, 20.0f, 320.0f, 460.0f)];
// [self.window addSubview:testView];
[self.window makeKeyAndVisible];
return YES;
}
它给了我这个错误
