如何删除NSURL的部分并将结果保存为具有格式的NSString？

Question

如何格式化file:///Applications/App%20Store.app存储为字符串"App Store"？我想删除"App%20Store.app"之前的所有内容,并使其在新存储的字符串中自动为%20添加空格.

我的代码从a获取用户输入NSOpenPanel()并将上面显示的结果保存到NSURL变量.

编辑得到它与此一起工作!谢谢

var URLinString : String = selectedApp!.absoluteString!

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

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

Objective-C的

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

迅速

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

安慰

Optional("App Store.app")
Yes
