Replace occurrences of space in URL

Question

I have a URL in an iPhone application to work with. But the problem is that it has some spaces in the URL. I want to replace the spaces with '%20'. I know that there are the stringByReplacingOccurencesOfString and stringByAddingPercentEscapesUsingEncoding methods. I also have used them. But they are not working for me. The spaces are replaced by some unusual values.

I'm applying those methods on an instance of NSString.

Answer 1

The correct format for replacing space from url is :

Objective C

NSString *urlString;//your url string.

urlString = [originalUrl stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

or

urlString = [originalUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

iOS 9 and later

urlString = [originalUrl stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

Swift :

var originalUrl = "https://google.com"
var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

ios 9 and later

var urlString :String = originalUrl.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!

Swift 4

var urlString = originalString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)

Swift 4.2

var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

Answer 2

Swift 2.0

let originalUrl = "http://myurl.com/my photo.png"
let urlNew:String = urlReq.stringByAddingPercentEncodingWithAllowedCharacters( NSCharacterSet.URLQueryAllowedCharacterSet())! 

Output:

http://myurl.com/my%20photo.png

Answer 3

To replace occurence in SWIFT 3 :

let updatedUrl = originalUrl.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)

Answer 4

Swift 4

Another way to replace an empty space with replacingOccurrences method:

let yourString = "http://myurl.com/my photo.png"
let urlNew:String = yourString.replacingOccurrences(of: " ", with: "%20").trimmed 

That will replace the empty space (" ") with '%20'

Answer 5

A Swift 4 solution. You simply pass through a string and it fills spaces with %20 and adds "http://" to the beginning to the string. Pretty sweet!

URL(fileURLWithPath: String) 

Answer 6

Swift 5

var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

Answer 7

var urlString :String = originalUrl.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)!

Answer 8

Hope this will work

let url = "https:youtube.56432fgrtxcvfname=xyz&sname=tuv"
let urlNew:String = url.replacingOccurrences(of: " ", with: "%20")
Alamofire.request(urlNew, method: .get, headers: headers).responseJSON{
response in
print(response)    
}

It will remove all kind of spaces from the url.

SWIFT 3.1

Simple way to replace an empty space with replacingOccurrences:

Answer 10

Swift 4, iOS-9

let **urlSearchVal**:String = "top 10 movies"     
let urlString = 

    "https://www.googleapis.com/youtube/v3/search?part=snippet&q=\(urlSearchVal)&key=......&type=video"   
//replace ...... above with your youtube key   
// to ignoring white space in search  
        let UrlString :String = urlString.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)!
