Replace occurrences of space in URL
提问by Joy
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 stringByReplacingOccurencesOfStringand stringByAddingPercentEscapesUsingEncodingmethods. I also have used them. But they are not working for me. The spaces are replaced by some unusual values.
我在 iPhone 应用程序中有一个 URL 可以使用。但问题是它在 URL 中有一些空格。我想用“%20”替换空格。我知道有stringByReplacingOccurencesOfString和stringByAddingPercentEscapesUsingEncoding方法。我也用过它们。但他们不为我工作。空格被一些不寻常的值取代。
I'm applying those methods on an instance of NSString.
我正在将这些方法应用于NSString.

Another way to replace an empty space with replacingOccurrences method:
另一种用replaceOccurrences方法替换空白空间的方法：
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'
这将用 '%20' 替换空白空间 (" ")

Hope this will work
希望这会奏效
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.
它将从 url 中删除所有类型的空格。

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

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!
Swift 4 解决方案。您只需传递一个字符串，它会用 %20 填充空格并将“http://”添加到字符串的开头。好甜！
