```
[client enqueueBatchOfHTTPRequestOperations:@[profileOperation,commFriendsOperation] progressBlock:^(NSUInteger finished, NSUInteger total){} completionBlock:^(NSArray *completedRequests){
//Code here
}]

```

The Code below are in an AFNetworking batch request success block. The instruments shows that codes blow have memory leak as it commented. However, I cannot figure out how did it leaked and how can I fix it, anybody has any idea?

Thanks in advance.

```
AFHTTPRequestOperation *commFriendsRequest = [completedRequests objectAtIndex:1];
    if(!commFriendsRequest.error&&commFriendsRequest.responseData){
        //Leak 46.2%

        int status1 = [[commDic objectForKey:@"status"]intValue];
        if(status1 == kSuccessCode){
            NSArray *commFriendsArray = [commDic objectForKey:@"data"];
            if(commFriendsArray&&commFriendsArray.count){
                //Leak 30.8%
                NSMutableArray *userItems = [NSMutableArray arrayWithCapacity:commFriendsArray.count];
                for(NSDictionary *dic in commFriendsArray){
                    //Leak 23.1%
