我不确定如何从我保存文件的documentsPath和目标路径获取url

let someText = Nsstring(string: "Test")        let documentsPath = NSSearchPathForDirectorIEsInDomains(.documentDirectory,.UserDomainMask,true)[0] as String        let destinationPath = documentsPath.stringByAppendingPathComponent("Data.txt")        var error:NSError?        let written = someText.writetofile(destinationPath,atomically: true,enCoding: NSUTF8StringEnCoding,error: &error)        if written{            println("Successfully stored the file at path \(destinationPath)")  let dic = UIdocumentInteractionController()   self.dic.URL = url            let v = sender as UIVIEw            let ok = self.dic.presentopenInMenuFromrect(                v.bounds,inVIEw: v,animated: true)

解决方法 将代码修改为以下内容

import UIKitclass VIEwController: UIVIEwController {    var docController:UIdocumentInteractionController!    overrIDe func vIEwDIDLoad() {        let someText = Nsstring(string: "Test")        if let documentsPath = NSSearchPathForDirectorIEsInDomains(.documentDirectory,true)[0] as? String {        let destinationPath = documentsPath.stringByAppendingPathComponent("Data.txt")        var error:NSError?        let written = someText.writetofile(destinationPath,error: &error)        if written{            println("Successfully stored the file at path \(destinationPath)")            }       if let url = NSURL(fileURLWithPath: destinationPath) {            docController = UIdocumentInteractionController(URL: url)        }        }    }    @IBAction func sendfile(sender:AnyObject) {    docController.presentoptionsMenuFromrect(sender.frame,inVIEw:self.vIEw,animated:true)    }}

现在将IBAction连接到故事板中的按钮.下一个：

>单击左侧栏中的蓝色项目图标,然后选择
水平菜单中的信息.
>展开文档类型,然后在名称字段中输入“txt”
“类型”字段中的“public.data,public.content”
>现在展开导出的UTI并在描述中输入“txt”
字段,标识符字段中的“kUTTypeText”和
Conforms to字段中的“public.data,public.content”

所以一切都是这样的：

您现在可以构建并运行应用程序进行测试.
