崩溃与OAuthTwitterController委托

Question

我得到一个当该委托函数被调用EXC_BAD_ACCESS：

OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername 

什么想法？

我的课是这样的：

@interface QuizzResultController: UIViewController <NSXMLParserDelegate,SA_OAuthTwitterControllerDelegate> { 


IBOutlet UILabel *resultLabel; 

IBOutlet UIButton *facebookButton; 
IBOutlet UIButton *twitterButton; 
IBOutlet UIButton *button3; 
// .... other variables ...// 

SA_OAuthTwitterEngine *_engine; 
SA_OAuthTwitterController *controller; 



} 

/// .m 

#pragma mark SA_OAuthTwitterControllerDelegate 


- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username{ 

    NSLog("@auth done with username : %@",username); 

} 

- (void) OAuthTwitterControllerFailed: (SA_OAuthTwitterController *) controller{ 

} 

- (void) OAuthTwitterControllerCanceled: (SA_OAuthTwitterController *) controller{ 

} 

在线程的用户名的NSLog的前碰撞发生时，以 “objc_msgSend” 1

你的日志语句不正确，应该是：

NSLog(@"auth done with username : %@",username);
