Trying to make a function to handle AFNetworking - ios

Question

I'm trying to make a function that I'll call to handle the AFNetworking JSON parse.
Here is my code:
- (int)startParseWithParameters:(NSDictionary*)incomingParameters andUrlAdress:(NSString*)urlAdress;
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSDictionary *parameters = incomingParameters;
[manager POST:urlAdress parameters:parameters success:^
(AFHTTPRequestOperation *operation, id responseObject)
{
NSString *recivedErr = responseObject[#"error"];
_errValue = [recivedErr intValue];
NSLog(#"JSON: %d", _errValue);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
return _errValue;
}
I want the function to return 0 or 1, then I'll know if there is an error or not.
Right now it always return 0.
When I try to return in the success block I get a compiler error.
What could cause this problem?

The succes block is handled async so you should just call a method in the block:
- (void)startParseWithParameters:(NSDictionary*)incomingParameters andUrlAdress:(NSString*)urlAdress {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSDictionary *parameters = incomingParameters;
__weak typeof(self) weakSelf = self;
[manager POST:urlAdress parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *recivedErr = responseObject[#"error"];
[weakSelf didReceiveResponse:[recivedErr integerValue];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
-(void)didReceiveResponse:(NSInteger)status {
}
