When i try to parse special char like "care&love", it just shows "care", the part after "&" truncated How can i make it to show the complete string???

```
NSURL *url = [NSURL URLWithString:urlStr];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url  cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

NSString *postJson = [NSString stringWithFormat:@"&json=%@", jsonRequest];

NSData *requestData = [postJson dataUsingEncoding:NSUTF8StringEncoding];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];

```
