How to make an NSURL that contains a | (pipe character)?

Question

I am trying to access google maps\' forward geocoding service from my iphone app. When i try to make an NSURL from a string with a pipe in it I just get a nil pointer.

Answer 1

As stringByAddingPercentEscapesUsingEncoding is deprecated, you should use stringByAddingPercentEncodingWithAllowedCharacters.

Swift answer:

let rawUrlStr = "http://maps.google.com/maps/api/geocode/json?address=6th+and+pine&bounds=37.331689,-122.030731|37.331689,-122.030731&sensor=false";
let urlEncoded = rawUrlStr.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
let url = NSURL(string: urlEncoded)

Edit: Swift 3 answer:

let rawUrlStr = "http://maps.google.com/maps/api/geocode/json?address=6th+and+pine&bounds=37.331689,-122.030731|37.331689,-122.030731&sensor=false";
if let urlEncoded = rawUrlStr.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) {
    let url = NSURL(string: urlEncoded)
}
