How can I remove part of NSURL and keep the result in NSString format?

How can I format it file:///Applications/App%20Store.app

to be stored as an App Store string? I want to remove everything up to "App% 20Store.app" and automatically add space for% 20 to the new saved row.

My code takes user input from NSOpenPanel()

and stores the result shown above into an NSURL variable.

EDIT . He works with it! Thanks to

var URLinString : String = selectedApp!.absoluteString!

let newString = URLinString.stringByReplacingOccurrencesOfString("file:///Applications/", withString: "")

let newerString = newString.stringByReplacingOccurrencesOfString("%20", withString: " ")

Objective-C

NSURL *url = [NSURL URLWithString:@"file:///Applications/App%20Store.app"];
NSString *lastComponent = [url lastPathComponent];
NSLog(@"Last path component:%@", lastComponent);

Swift



var url = NSURL(string:"file:///Applications/App%20Store.app")
var lastComponent = url?.lastPathComponent
println("\(lastComponent)")
if lastComponent == "App Store.app" {
  println("Yes")
}

Console

Optional("App Store.app")
Yes

According to what you say, you want to get the filename.

You can use methods of the NSString class (Edited thanks to comments)

In Objective-C :



NSURL *myNSURL = [NSURL URLWithString:@"file:///Applications/App%20Store.app"];

//Extract filename and remove file extension
NSString* fileName = [[myNSURL lastPathComponent] stringByDeletingPathExtension];

In Swift :

var myNSURL = NSURL(string:"file:///Applications/App%20Store.app")

//Extract filename and remove file extension
var fileName = myNSURL?.lastPathComponent?.stringByDeletingPathExtension

}
