Cannot assign UIImage from NSURL because of string encoding

Question

This is my simple UIImageView extension:

extension UIImageView {

    func setImageWithString(string: String?) {

        if let string = string, let url = NSURL(string: string) {
            sd_setImageWithURL(url)
        }
    }
}

And for the following string I cannot get inside condition:

"http://posbistro-prod.s3.amazonaws.com/location_images/images/116/2fa/ad-/medium/Bez tytułu.jpg"

How can I workaround this?

Have you tried something with url percentage encoding (stringByAddingPercentEscapesUsingEncoding) ? take a look at this as well http://stackoverflow.com/questions/26353388/stringbyaddingpercentescapesusingencodingnsutf8stringencoding-returns-optional — Miknash, Jul 18 '16 at 14:22
try to encode your url, like: `let encodedPath = string.URLString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())` — Duyen-Hoa, Jul 18 '16 at 14:23

do like

func setImageWithString(stringbyName: String?) {

     let urlStr = stringbyName.stringByAddingPercentEncodingWithAllowedCharacters(. URLQueryAllowedCharacterSet())

    if let  url = NSURL(string: urlStr) {
        sd_setImageWithURL(url)
    }
}

or use like

   func setImageWithString(stringbyName: String?) {

     let urlStr = stringbyName.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)

    if let  url = NSURL(string: urlStr) {
        sd_setImageWithURL(url)
    }
}

@BartłomiejSemańczyk - that the reason I added the first choice , I think you need to change the type of `URLQueryAllowedCharacterSet` or `URLHostAllowedCharacterSet` else try once you get answewr – Anbu.Karthik Jul 18 '16 at 14:33
@BartłomiejSemańczyk - sure – Anbu.Karthik Jul 18 '16 at 14:34
Thank you, the first one with `URLQueryAllowedCharacterSet` worked fine:) – Bartłomiej Semańczyk Jul 18 '16 at 16:03
