Xcode 8.0 和 swift 3.0 中的 ScriptingBridge 代码错误

Question

这是我在 Xcode 7.3.1 中使用的代码，运行良好：

    var selectedFiles = NSMutableArray(capacity:1)
    let  finder: AnyObject! = SBApplication(bundleIdentifier:"com.apple.finder")
    let finderObject = finder.selection as! SBObject
    let selection: AnyObject! = finderObject.get()
    let items = selection.arrayByApplyingSelector(Selector("URL"))

    let filteredfiles = (items as NSArray).pathsMatchingExtensions(["ai","pdf","ap","paf","pafsc"])
    for  item in filteredfiles {
        let url = NSURL(string:item ,relativeToURL:nil)
        selectedFiles.addObject(url!)
    }

这是针对 Xcode 8.0 更正的代码，但不起作用： 最后一行产生错误

error = 不能调用非函数类型'[Any]!'的值

    var selectedFiles = NSMutableArray(capacity:1)
    let  finder: AnyObject! = SBApplication(bundleIdentifier:"com.apple.finder")
    let finderObject = finder.selection as! SBObject
    if let selection = finderObject.get()  as AnyObject?{
        let items =  selection.array(#selector(getter: NSTextCheckingResult.url))
        let filteredfiles = (items as NSArray).pathsMatchingExtensions(["ai","pdf","ap","paf","pafsc"])
        for  item in filteredfiles {
          let url = NSURL(string:item ,relativeToURL:nil)
          selectedFiles.addObject(url!)
       }
    }

我尝试了很多解决方案，但不幸的是找不到线索。 我猜这是因为 Swift 3.0x API 发生了巨大的变化...... 欢迎任何帮助！

Answer 1

这是一种稍微不同的方法，它使用了 Swift 3 的几个原生 Swift 函数

var selectedFiles = [URL]()
let  finder : AnyObject = SBApplication(bundleIdentifier:"com.apple.finder")!
let finderObject = finder.selection as! SBObject
if let selection = finderObject.get() as? [SBObject] {
  selection.forEach { item in
      let url = URL(string: item.value(forKey:"URL") as! String)!
      selectedFiles.append(url)
    }

  let goodExtensions = ["ai","pdf","ap","paf","pafsc"]
  let filteredURLs = selectedFiles.filter({goodExtensions.contains($0.pathExtension)})
  print(filteredURLs)
}

PS：我强烈推荐使用AppleScriptObjC。它更容易使用。

PPS：valueForKey 是故意使用的，因为确实需要 KVC 来获取属性值。
