ios - how to make function to return after the AFHTTPRequestOperation has done

Question

I want the function do not return until the AFHTTPRequestOperation finished, but I did not know how to do it, thanks in advance.

-(BOOL)download
{
BOOL ret = TRUE;
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    ret = [self handle:data];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Failure: %@", error);
}];
[operation start];
return ret ;
}

Answer 1

Your design is incorrect.

AFHTTPRequestOperation is asynchronous so you cannot (and you shouldn't) treat it in a synchronous way. You have to modify your workflow in order to use the completion or failure blocks of the AFHTTPRequestOperation.
