针对iOS进行解析：尝试运行应用程序时出错

Question

我一直在使用Parse SDK，并且遵循了快速步骤指南。当我尝试运行时，出现了这8个错误。有什么想法吗？似乎与我未使用的Parse的Facebook部分有关。

与下载，编译和安装FB工具包相比，这是一种潜在的更简单的解决方法，该工具包又大又麻烦。请注意，当然，您将无法使用Parse中的任何FB类型功能，并且如果触发任何期望使用这些虚拟符号的Parse代码，则会遇到严重问题。但是，我想，如果您远离他们，您会没事的。所以...在您的应用程序中创建一个名为FBMissingSymbols的对象删除不需要的.h把它放在.m中：NSString *FBTokenInformationExpirationDateKey = @"";NSString *FBTokenInformationTokenKey = @"";NSString *FBTokenInformationUserFBIDKey = @"";@interface FBAppCall:NSObject@end@implementation FBAppCall@end@interface FBRequest:NSObject@end@implementation FBRequest@end@interface FBSession:NSObject@end@implementation FBSession@end@interface FBSessionTokenCaching:NSObject@end@implementation FBSessionTokenCaching@end@interface FBSessionTokenCachingStrategy:NSObject@end@implementation FBSessionTokenCachingStrategy@end

我喜欢dbquarrel的答案，但是由于缺少一些新的社会阶层，它不再起作用了。所以做同样的事情，但是添加以下内容：NSString *FBTokenInformationExpirationDateKey = @"";NSString *FBTokenInformationTokenKey = @"";NSString *FBTokenInformationUserFBIDKey = @"";NSString *SLServiceTypeTwitter = @"";NSString *ACAccountTypeIdentifierTwitter = @"";@interface FBAppCall:NSObject@end@implementation FBAppCall@end@interface FBRequest:NSObject@end@implementation FBRequest@end@interface FBSession:NSObject@end@implementation FBSession@end@interface FBSessionTokenCaching:NSObject@end@implementation FBSessionTokenCaching@end@interface FBSessionTokenCachingStrategy:NSObject@end@implementation FBSessionTokenCachingStrategy@end@interface ACAccountStore:NSObject@end@implementation ACAccountStore@end@interface SLRequest:NSObject@end@implementation SLRequest@end@interface SLComposeViewController:NSObject@end@implementation SLComposeViewController@end
