How to deal with space value in text view and text field using swift

Question

I am developing an app using Swift. In my app, I am getting a value from a UITextField and a UITextView and sending that value as a parameter to a JSON API. I am able to send the value, but when I send the value with white space, my app crashes and shows error as null value. But I need to send the value with space also. For example, getting the full name or address.

Code:

 Alamofire.request(.GET, "https://www.something.com/cid="+MyCustId+"", parameters: nil, encoding: .URL, headers: nil).response { (req, res, data, error) -> Void in
                let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
                print(dataString)

}

Here, MyCustId is the variable which is getting the value from UITextField. Thanks in advance!

For URLs, space is a special character and needs to be percent encoded. — Eric Aya, Jan 31 '17 at 15:45

You should replace spaces with %20 in the URL by the following method.

func addPercentageToUrl(urlString : String) -> String{

            return urlString.addingPercentEncoding( withAllowedCharacters: .urlQueryAllowed)!
        }


func makeService(){
let url = addPercentageToUrl(urlString : "https://www.something.com/cid="+MyCustId+"")
Alamofire.request(.GET, url, parameters: nil, encoding: .URL, headers: nil).response { (req, res, data, error) -> Void in
                let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
                print(dataString)

}
}

Please update you code like this.

can you elaborate please – user7333282 Jan 31 '17 at 12:39
It means that when you are adding spaces in your Url which is "https://www.something.com/cid="+MyCustId+"" this is not valid. When you try to add a space in Url then web browser automatically add %20 in place of spaces while programmatically you have to add %20 in places of spaces in the Url so that it successfully hit the server. – Usman Javed Jan 31 '17 at 12:42

please use stringByAddingPercentEncodingWithAllowedCharacters method for adding space in url

let myStr = strOfUrl.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()
