我有一个注册方法，命中一个API来注册一个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，当注册成功时，我弹出注册视图。一旦我弹出注册视图，我会在下面一行获得EXC_BAD_ACCESS。注 - 这只发生在手机上。在模拟器中，这不会发生。不知何故，这似乎是一个时间问题，但我无法弄清楚。例如，如果我在[_completionHandlerSignUp版本]上放置了breakpointer;那么它每次都有效。iOS的ASIFormDataRequest崩溃
这里是我的DataAccessor类我的createAccount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;
}];
这里是视图 - 控制方法：
DataAccessor *dataAccessor = [[DataAccessor alloc] init];
[dataAccessor createAccount:[Utilities getDeviceUDID] user:txtEmail.text password:txtPassword.text firstname:txtFirstName.text lastname:txtLastName.text completion:^(Account *myAccount)
{
[dataAccessor release];
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];
[self popViewController]; **<<<<If I remove this, THERE IS NO CRASH******
}
else if(myAccount.statusCode == 403)
{
//todo - handle error
}
}
[self finalUpdate];
}];
- (void) popViewController
{
NSLog(@"TEST - Popping View Controller ");
CATransition* transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
transition.subtype = kCATransitionFromBottom; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
// MainSelectionMenu *myViewController = [[MainSelectionMenu alloc] initWithNibName:@"MainSelectionMenu" bundle:nil];
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[[self navigationController] popViewControllerAnimated:NO];
}
别的东西，这是非常奇怪的是，我的登录功能的作品几乎完全一样。登录调用DataAccessor中的SignIN API，当它在视图控制器中返回时，它会弹出视图。但是，登录功能工作正常，从不崩溃。

嗯，出于某种原因，我可以让它在模拟器中崩溃，一旦僵尸启用，罪魁祸首是ASIFormDataRequest GraphicsServices，但真的没有其他信息：/ – Jesse 2012-01-27 19:45:58
你可以发布僵尸启用时收到的完整错误消息吗？ – mccrackend 2012-01-27 19:50:47
添加它，遗憾的格式，但不知道怎么回事，以显示它在SO – Jesse 2012-01-27 20:06:06
