iOS ASIFormDataRequest崩溃

我有一个注册方法，可以点击API注册用户并返回帐户信息。一切正常，但在我的注册视图控制器中，注册成功后，我会弹出注册视图。一旦我弹出“注册”视图，我就可以在下面的行中访问EXC_BAD_。注意-这只发生在电话上。在模拟器中，这不会发生。不知怎么的，这似乎是个时间问题，但我想不出来。例如，如果我在[_CompletionHandlerSignupRelease]上放置了一个断点；然后它每次都能工作

以下是我的DataAccessor类中的CreateCount方法：

_completionHandlerSignUp = [handler copy];

the normal request code would be here

[request setCompletionBlock:^
 {
     int statusCode = request.responseStatusCode;

     NSDictionary *json = [request.responseString JSONValue];
     NSString *status = [json valueForKeyPath:@"status"];
     NSLog(@"API JSON %@", request.responseString);

     myAccount.statusCode = statusCode;

     if(statusCode == 200)
     {
         myAccount.status = status;
         myAccount.error = @"";
         myAccount.firstName = firstName;
         myAccount.lastName = lastName;
         Credentials *myCredentials = [[Credentials alloc] init];
         myCredentials.emailAddress = userName;
         myCredentials.passWord = passWord;
         myAccount.credentials = myCredentials;

         [myCredentials release];
     }
     else if(statusCode == 403)
     {
         NSString *error = [json valueForKeyPath:@"error"];
         myAccount.status = status;
         myAccount.error = error;
         NSLog(@"API Error %@",error);
     }

     NSLog(@"TEST - Sending Account Response ");
     _completionHandlerSignUp(myAccount);

     NSLog(@"TEST - DEALLOCATING OBJECTS ");

    [_completionHandlerSignUp release];  <--**EXC_BAD_ACCESS HAPPENS HERE**
    _completionHandlerSignUp = nil;

     }];

\u completionHandlerSignUp=[handler copy]；
正常的请求代码在这里
[请求setCompletionBlock:^
{
int statusCode=request.responseStatusCode；
NSDictionary*json=[request.responseString JSONValue]；
NSString*状态=[json valueForKeyPath:@“状态”]；
NSLog（@“API JSON%@”，request.responseString）；
myAccount.statusCode=状态代码；
如果（状态代码==200）
{
myAccount.status=状态；
myAccount.error=@；
myAccount.firstName=firstName；
myAccount.lastName=lastName；
凭证*myCredentials=[[Credentials alloc]init]；
myCredentials.emailAddress=用户名；
myCredentials.passWord=密码；
myAccount.credentials=我的凭证；
[myCredentials release]；
}
否则如果（状态代码==403）
{
NSString*error=[json valueForKeyPath:@“error”]；
myAccount.status=状态；
myAccount.error=错误；
NSLog（@“API错误%@”，错误）；
}
NSLog（@“测试-发送帐户响应”）；
_completionHandlerSignUp（我的帐户）；
NSLog（@“测试-释放对象”）；
[\u completionHandlerSignUp release]；打开僵尸对象以获取有关EXE\u BAD\u访问错误的更多详细信息。应该告诉您有关该对象的一些信息，该对象预期会出现在那里。这通常意味着您在执行代码时过早释放了对象指针

打开僵尸：

删除此[\u completionHandlerSignUp发行版]时会发生什么情况行？
Hmm，出于某种原因，我曾在启用僵尸的情况下让它在模拟器中崩溃过一次，罪魁祸首是ASIFormDataRequest GraphicsServices，但实际上没有其他信息：/n您能发布启用僵尸时收到的完整错误消息吗？添加了它，对格式感到抱歉，但不确定如何在SOfigured中显示它，dumb和往常一样是一个简单的错误：）顺便说一句，如果你使用的是iOS 5，使用ARC可以省去很多麻烦。你必须为一些ASIHttpRequest类添加编译器标志，但这是非常值得的。我确实让僵尸运行了，看看上面。而且，当我删除这一行时，它的行为也没有什么不同。

            if(myAccount != NULL)
            {
                NSLog(@"Status: %@", myAccount.status);
                NSLog(@"Error: %@", myAccount.error);

                if(myAccount.statusCode == 200)  //handle successful transaction
                {

                    [Preferences signInUser:myAccount.credentials.emailAddress password:myAccount.credentials.passWord];
