崩潰與OAuthTwitterController委託

Question

我得到一個當該委託函數被調用EXC_BAD_ACCESS：

OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername 

什麼想法？

我的課是這樣的：

@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{ 

} 

在線程的用戶名的NSLog的前碰撞發生時，以 「objc_msgSend」 1

你的日誌語句不正確，應該是：

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