与OAuthTwitterController委托崩溃

Question

调用此委托函数时，我得到一个EXC_BAD_ACCESS：

 OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername

任何想法？

我的班级看起来像这样：

@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{

}

崩溃发生在用户名的NSLog之前，在线程1中使用“objc_msgSend”

Answer 1

您的日志声明不正确，应该是：

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