中止在iPhone模拟器

我对这个代码loginButton.enabled = YES;的最后一行接收SIGABRT错误。它今天早上工作，现在这个错误出现了。中止在iPhone模拟器

-(IBAction)login:(id)sender 
{ 
    UIButton *loginButton = (UIButton *)sender; 
    loginButton.enabled = NO; 
    NSString *filePath = [self dataFilePath]; 
    if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) 
    { 
     NSArray *array = [[NSArray alloc] initWithContentsOfFile:filePath]; 
     NSString *nameString = [[NSString alloc] init]; 
     NSString *contactIdString = [[NSString alloc] init]; 
     NSString *genderString = [[NSString alloc] init]; 
     NSString *contactTypeString = [[NSString alloc] init]; 
     nameString = [array objectAtIndex:0]; 
     contactIdString = [array objectAtIndex:1]; 
     genderString = [array objectAtIndex:2]; 
     contactTypeString = [array objectAtIndex:3]; 

     self.name = nameString; 
     self.contactId = contactIdString; 
     self.gender = genderString; 
     self.contactType = contactTypeString; 
     [self.userArray removeAllObjects]; 
     [self performSelectorInBackground:@selector(sendData) withObject:nil]; 

     [nameString release]; 
     [contactIdString release]; 
     [genderString release]; 
     [contactTypeString release]; 

     UIBarButtonItem *logoutButton = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStylePlain target:self action:@selector(logout:)]; 

     //[logoutButton setTitle:@"Logout"]; 
     [[self navigationItem] setRightBarButtonItem:logoutButton]; 
     [logoutButton release]; 
    } 
    else 
    { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"New User" message:@"It seems you have not used FaceDirectory before, please go to My Details and fill out the information then click save." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; 
     [alert show]; 
     [alert release]; 
    } 
    loginButton.enabled = YES; 
}

这是错误转储。

我刚刚在我的iPhone上检查过它，并且应用程序没有崩溃。它只发生在模拟器上。

是您loginbutton的RightBarButtonItem？ –

集NSZombieEnabled是的，它会告诉你正确的崩溃原因.. – PJR

普利文是的，它是RightBarButtonItem。 – mintuz

我猜的错误是从FaceConnect传播。请检查，它显示了很多泄漏和警告。

有趣.....我通过将Bundle显示名称更改为FaceConnect而不是$（PRODUCT_NAME）来改变我的应用程序的名称吗？ – mintuz

是啊，很可能是，我只是伤心的通过看你的代码，以便涉足自己提高清洁方式代码，我没有完全看你的崩溃日志，因为它不是最初发布，感谢@Gilles编辑和后来我会显示你的崩溃日志。您可以随时使用** malloc_history **进行检查。 –

创建与分配/初始化空字符串，那么你改变它们的值由objectAtIndex:返回。这会导致指针指向自动发布的值。释放字符串后，应用程序将崩溃，因为保留计数将小于零。

更新它，我从未有过的一个问题，它只是停止工作：S – mintuz

检查我的问题，我有一点点的信息 – mintuz

阅读我的答案更新它这是编写代码的更简洁的方式。 –

-(IBAction)login:(id)sender { 

    [(UIButton*) sender setEnabled:NO]; 

    if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { 
    NSArray *array = [[NSArray alloc] initWithContentsOfFile:filePath]; 

    NSString* name = [array objectAtIndex:0]; 
    NSString* contactId = [array objectAtIndex:1]; // depends if it is an integer then use int 
    NSString* gender = [array objectAtIndex:2]; 
    NSString* contactType = [array objectAtIndex:3]; 

    //[self.userArray removeAllObjects]; // what is your user array and why you are removing all the objects 
            // i could not find where you are setting the value for userArray 
    [self.userArray arrayWithObjects:self.name, self.contactId, self.gender,self.contactType, nil]; 

    [self performSelectorInBackground:@selector(sendData) withObject:nil]; 

    /*if (loginButton.selected == NO) { 
    // Represents user needs to login. Code for login user. 
    }else 
    { 
    [loginButton setTitle:@"Logout"]; 
    } 

    // toggle the login/logout states. 
    loginButton.selected = !loginButton.selected;*/ 

    UIBarButtonItem *logoutButton = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStylePlain target:self action:@selector(logout:)]; 

    //[logoutButton setTitle:@"Logout"]; 
    [[self navigationItem] setRightBarButtonItem:logoutButton]; 
    [logoutButton release]; 
} 

else { 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"New User" message:@"It seems you have not used FaceDirectory before, please go to My Details and fill out the information then click save." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; 

    [alert show]; 
    [alert release]; 

} 
[(UIButton*) sender setEnabled:YES]; 

}

我找不到你在哪里设置userArray的价值，所以我想，我认为你要绑定的信息，以userArray和发送

-(id)sendData{ 
    //Do whatever you want to do with userArray 
} 


-(void)viewDidUnLoad{ 
     self.userarray = nil; 
     [super viewDidlUnload]; 
} 
-(void)dealloc{ 
    [userArray release]; 
    [super dealloc]; 
    }

它仍然在loginButton.enabled上出现相同的错误= YES – mintuz

我喜欢Control-V的更干净的代码。代码更干净，最容易跟踪错误和控制代码。 – mysticboy59

userarray是不同的东西，它用来为bk提供一个在线用户列表。 – mintuz
