无法识别的选择器发送到OAuthCore类中的类-UnrecognizedselectorsenttoclassinOAuthCoreclass

I have created one library project, in that i am trying to Twitter sharing. But when i tried to on Twitter the application is crashes at following line

我创建了一个图书馆项目,因为我正在尝试Twitter共享。但当我尝试在Twitter上时,应用程序崩溃在以下行

NSString *_oAuthNOnce= [NSString ab_GUID];

by error:

+[NSString ab_GUID]: unrecognized selector sent to class 0x1a09fd8

+ [NSString ab_GUID]:发送到类0x1a09fd8的无法识别的选择器

ab_GUID this method is present in OAuthCore class

ab_GUID此方法存在于OAuthCore类中

+ (NSString *)ab_GUID
{
    CFUUIDRef u = CFUUIDCreate(kCFAllocatorDefault);
    CFStringRef s = CFUUIDCreateString(kCFAllocatorDefault, u);
    CFRelease(u);
    return [(NSString *)s autorelease];
}

(My all classes are present in static Library)

(我的所有类都出现在静态库中)
