Send NSString variable to WCF service

Question

I have encountered an issue with my code, when I want to send an NSString variable to my WCF web service.

Code:

NSString *str= @"http://IPdAddress/myService.svc/json/";
str=[str stringByAppendingFormat:@"InsertNewWeight/%@",noteWeight.text];

NSURL *WcfSeviceURL = [NSURL URLWithString:str];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:WcfSeviceURL];

[request setHTTPMethod:@"POST"];

This code is working fine if I enter the noteWeight.text value as a simple word.

When I entered the noteWeight.text value as a complex word (two words separated by a space) the system returns an error data parameter is nil

Can anybody help me please on this? Thank you.

As it is passed in the URL and not as a POST argument, you should URL-encode your noteWeight.text string, like this:

str = [str stringByAppendingFormat:@"InsertNewWeight/%@", [noteWeight.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

The spaces will be sent as %20, and other special characters will also be encoded to be correctly read on the server-side.
