My app crashes at line 4 in URLSession:dataTask:didReceiveResponse:completionHandler of AFURLSessionManager.m，it looks like the self object is launched:
- (void)URLSession:(NSURLSession *)session
dataTask:(NSURLSessionDataTask *)dataTask
didReceiveResponse:(NSURLResponse *)response
completionHandler:(void (^)(NSURLSessionResponseDisposition disposition))completionHandler
{
1 NSURLSessionResponseDisposition disposition = NSURLSessionResponseAllow;
2
3 if (self.dataTaskDidReceiveResponse) {
4 disposition = self.dataTaskDidReceiveResponse(session, dataTask, response);(line 1115 of unique m file)
5 }
6
7 if (completionHandler) {
8 completionHandler(disposition);
9 }
10 }
