AFN synchronous asynchronous request and afn synchronous asynchronous request

Asynchronous request:

-(BOOL) getOnlyKey1 {NSString * myUUIDStr = [[UIDevice currentDevice] identifierForVendor] UUIDString]; _ block bool isTrue = false; AFHTTPRequestOperationManager * manager = [Queue manager]; manager. responseSerializer. acceptableContentTypes = [NSSet setWithObject: @ "text/plain"]; NSString * urlstr = [NSString stringWithFormat: @ "http: // 122.225.89.70: 28080/try/check"]; NSURL * url = [NSURL URLWithString: urlstr]; NSDictionary * dic =@{@ "imei": myUUIDStr, @ "av": AppVersion}; [manager POST: urlstr parameters: dic success: ^ (AFHTTPRequestOperation * operation, id responseObject) {MyLog (@ "% @", operation. responseString); nsange range = [operation. responseString rangeOfString: @ "\" msg \ ": \" 0 \ ""]; if (range. location! = NSNotFound) {isTrue = true;} if (!

Synchronous request:

Original Ecological synchronization request:

Method. The synchronization operation is not completed, and subsequent code will not be executed. NSData * data = [NSURLConnection sendSynchronousRequest: request returningResponse: & response error: & error]; // NSString * str = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; // MyLog (@ "returned result: % @", str); if (error = nil) {// receives data, NSString * str = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; MyLog (@ "% @", str); nsange range = [str rangeOfString: @ "\" msg \": \ "0 \" "]; if (range. location! = NSNotFound) {return true;} else {return false; UIAlertView * alert = [[UIAlertView alloc] initWithTitle: @ "error bird" message: @ "you need to contact the project developer" delegate: nil cancelButtonTitle: @ "OK" otherButtonTitles: nil]; [alert show] ;}} if (error! = Nil | response = nil) {return false; UIAlertView * alert = [[UIAlertView alloc] initWithTitle: @ "error" message: @ "login failed, network instability "delegate: nil cancelButtonTitle: @" OK "otherButtonTitles: nil]; [alert show];} return false ;}
