Replace occurrences of space in URL - ios

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 :
Swift 4.2 , Swift 5
var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
Swift 4
var urlString = originalString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)
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]];

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

Swift 5
var urlString = originalString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

Answer 6

Swift 5.3, clear space your string,
let str = " www.test.com "
let trimmed = str.trimmingCharacters(in: .whitespacesAndNewlines)
print(str) // "www.test.com"

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.

Answer 9

The quickest solution: just use the stringy method...
.replacingOccurrences(of: " ", with: "%20")
...at the end of your string, and it will do as it says.
Apple should be EMBARRASSED that their URL(string: ) method doesn't automatically do this (and more). It's 2023 and I wasted 3 hours finding this half-assed solution.
My specific example was inside cellForItemAt and having to do with optionals.
let stringOfImageURLFromFirebase = wordController?.word?.images[indexPath.item].imgUrl
let stringWithNoSpaces = string?.replacingOccurrences(of: " ", with: "%20")
if let imageURLString = stringWithNoSpaces,
let imageURL = URL(string: imageURLString) {
cell.definitionImageView.loadImageFromFirebase(url: imageURL)
} else {
cell.definitionImageView.image = UIImage(named: "slictionarylogo")
}
You can fuddle with .addingPercentEncoding for a long time, try NSURL nonsense, and you'll just be faster with using the obvious. Apple sucks, and should've made this painfully easy since it's such a common problem. Again, they are asleep at the wheel, and their documentation is AWFUL too.

Answer 10

SWIFT 3.1
Simple way to replace an empty space with replacingOccurrences:
URL = URL.replacingOccurrences(of: " ", with: "", options: .literal, range: nil)

Answer 11

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)!

Answer 12

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)
