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
.
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]];
