Approval Error in - [AFHTTPRequestSerializer requestWithMethod: URLString: parameters: error:]

Question

Whenever I run this function, I get an assertion error, what should I do

[MBProgressHUD showHUDAddedTo:self.view animated:YES]; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSString *link = [NSString stringWithFormat:@"%@device_model_no=%@&device_serial_no=%@&device_imei=%@&note=%@&disclaimer=%@&extra_note=%@&package_plan=%@&price=%@&duration=%@&device=%@&user_reg_id=%@&device_category=%@",KURL,txtModelNumber.text,txtSerialNo.text,txtIMEI.text,txtViewExtra.text,deviceDisclamer,additonalDetail.text,plan,price,duration,deviceName,userID,nil]; NSLog(@"%@",link); manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"]; [manager GET:link parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); NSLog(@"%@", responseObject); NSDictionary *returnedDealDict = responseObject ; NSArray *returnArray = [returnedDealDict objectForKey:@"result"]; for(NSDictionary *dealDict in returnArray) { if ([dealDict objectForKey:@"success"]) { ALERT_VIEW(@"Thanks1! Your information has been saved Successfully! We will contact you soon.") } else { ALERT_VIEW(@"Your information doesn t exist in our database, Please go back and enter your contact info again!") } } success(); [MBProgressHUD hideHUDForView:self.view animated:YES]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); ALERT_VIEW(@"Error occured while loading data."); NSLog(@"getBrandDevice Error"); [MBPro gressHUD hideHUDForView:self.view animated:YES]; }]; 

I get this error

Answer 1

you need to add this line of code to avoid an invalid parameter url string

  NSString *encoded = [link stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

Answer 2

• (nullable NSString *) stringByAddingPercentEscapesUsingEncoding: (NSStringEncoding) enc NS_DEPRECATED (10_0, 10_11, 2_0, 9_0, "Use -stringByAddingPercentEncodingWithAllowedCharacters: it’s recommended to use a different code for this The URL component or subcomponent has different rules for which characters are valid. ");

The @NullData answer works fine right now, but the stringByAddingPercentEscapesUsingEncoding method stringByAddingPercentEscapesUsingEncoding deprecated, so you guys should use the stringByAddingPercentEncodingWithAllowedCharacters method stringByAddingPercentEncodingWithAllowedCharacters .

like this for quick

 let path = myurlstring.stringByAddingPercentEncodingWithAllowedCharacters( NSCharacterSet.URLQueryAllowedCharacterSet()) 

or is it for objc

 path = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]; 

Answer 3

Invalid url address, there are spaces, invalid characters, etc. For instance:
