    <p>In iOS, I want to send JSON data in URL to make service call. I tried following code snipped but Encoded URL seems wrong. Because in JSON there is a colon character (:) between key and value and comma character (,) for separation. But, i am not able to encode colon(:) as <strong>%3A</strong> and comma(,) as <strong>%2C</strong></p> <p><strong>Code Snippet:</strong></p> <pre><code>- (NSURL *)getEncodedUrl { // Build dictionnary with parameters NSString *abc = @"abc"; NSNumber *limitNumber = [NSNumber numberWithInt:2]; NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary]; [dictionnary setObject:limitNumber forKey:@"limit"]; [dictionnary setObject:abc forKey:@"abc"]; NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary options:0 error:&amp;error]; if (!jsonData) { debug("Json error %@",error); return nil; } else { NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding]; debug("Json op %@",JSONString); NSString* params = [JSONString stringByAddingPercentEscapesUsingEncoding: NSASCIIStringEncoding]; NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://baseUrl.com?param=@",params]]; debug("URL = %@",url); return url; } } </code></pre> <p><strong>OUTPUT:~</strong></p> <p>URL = <a href="http://baseUrl.com?param=%7B%22abc%22:%22abc%22,%22limit%22:2%7D" rel="nofollow">http://baseUrl.com?param=%7B%22abc%22:%22abc%22,%22limit%22:2%7D</a></p> <p>(Include colon and comma characters)</p> <p>But I want following o/p:</p> <p><strong><a href="http://baseUrl.com?param=%7B%22abc%22%3A%22abc%22%2C%22limit%22%3A2%7D" rel="nofollow">http://baseUrl.com?param=%7B%22abc%22%3A%22abc%22%2C%22limit%22%3A2%7D</a></strong></p> <p>(No colon and comma characters)</p> <p>Online Encoding-Decoding Site that I am referring as of now. </p> <p><a href="http://www.url-encode-decode.com/" rel="nofollow">http://www.url-encode-decode.com/</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
