Some of my http request has ‘space’ in URL, but it is not recognized

  • 0

Some of my http request has ‘space’ in URL, but it is not recognized by iPhone. I have to change ‘space’ to ‘%20’ whenever there is a ‘space’ in the url. Now I have to send a message typed by the user to the server and it can have as many ‘spaces’ as the user like. It looks like I have to replace them all.(stringByReplacingOccurrencesOfString)

Convert ‘space’ to ‘%20’ is the one I occasionally find. My question is which of the other characters in NSString cannot be straightly used by url on iPhone?

  1. I think this is a better approach:

    NSString* escapedUrl = [originalUrl    stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    If you want to understand how URL encoding works, take a look at this URL.
