【问题描述】：

嗨，有人能指出我正确的方向吗？我正在使用最新的 Xcode 和 swift 我已经设法复制 plist 并阅读它，但它不会写？非常感谢任何帮助

var NameOfPlist = "Data"

func CopyPlistAndReadContentsToAnArray(NameOfPlist:String)


let url = NSURL(string: NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, .UserDomainMask, true)[0])
let  plistPathInDocument = (url?.URLByAppendingPathComponent(NameOfPlist + ".plist").absoluteString)!

if !NSFileManager.defaultManager().fileExistsAtPath(plistPathInDocument)

    let plistPathInBundle = NSBundle.mainBundle().pathForResource(NameOfPlist, ofType: "plist")!
    do
    
        try NSFileManager.defaultManager().copyItemAtPath(plistPathInBundle, toPath: plistPathInDocument)
        let levelPlist =  plistPathInDocument
        MainArray = NSMutableArray(contentsOfFile: levelPlist)!
        print("plist copied")
    
    catch
    
        print("error copying plist!")
    

else

    let levelPlist =  plistPathInDocument
    MainArray = NSMutableArray(contentsOfFile: levelPlist)!
    print("PlistInDocOk")
    // print("plst  \(plistPathInDocument)") // = Data/Application/7D6891BB-2EE5-4D1A-8EB5-73B8100F0827/Documents/Data.plist
    // print("This is the MainArray \(MainArray)")






func SaveToPlist(NameOfPlist:String)

let url = NSURL(string: NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, .UserDomainMask, true)[0])
let  plistPathInDocument = (url?.URLByAppendingPathComponent(NameOfPlist).absoluteString)!
MainArray.writeToFile(plistPathInDocument, atomically: true)
print("Item Added")

【参考方案1】：

所以我今天早上很早就醒了，以为我要破解这个我把这行放在保存 plist 函数中

print("plst \(plistPathInDocument)")

这告诉我 .plist 丢失了 所以我添加了

MainArray.writeToFile(plistPathInDocument + ".plist", atomically: true)

所以现在它完全可以工作了整个代码希望这对某人有所帮助，因为我很难在 Swift 2 中找到如何做到这一点

用于保存 plist 名称的变量，以便您可以轻松交换 plist

  var NameOfPlist = "Data"

如果 plist 不存在则将其移动到文档并阅读它的功能

func CopyPlistAndReadContentsToAnArray(NameOfPlist:String)


let url = NSURL(string: NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, .UserDomainMask, true)[0])
let  plistPathInDocument = (url?.URLByAppendingPathComponent(NameOfPlist + ".plist").absoluteString)!

if !NSFileManager.defaultManager().fileExistsAtPath(plistPathInDocument)

    let plistPathInBundle = NSBundle.mainBundle().pathForResource(NameOfPlist, ofType: "plist")!
    do
    
        try NSFileManager.defaultManager().copyItemAtPath(plistPathInBundle, toPath: plistPathInDocument)
        let levelPlist =  plistPathInDocument
        MainArray = NSMutableArray(contentsOfFile: levelPlist)!
        print("plist copied")
    
    catch
    
        print("error copying plist!")
    

else

    let levelPlist =  plistPathInDocument
    MainArray = NSMutableArray(contentsOfFile: levelPlist)!
    print("Plist In Doc Ok")
    print("plst  \(plistPathInDocument)") // = Data/Application/7D6891BB-2EE5-4D1A-8EB5-73B8100F0827/Documents/Data.plist
    // print("This is the MainArray \(MainArray)")
   

保存到 plist 的函数

func SaveToPlist(NameOfPlist:String)


let url = NSURL(string: NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, .UserDomainMask, true)[0])
let  plistPathInDocument = (url?.URLByAppendingPathComponent(NameOfPlist).absoluteString)!
MainArray.writeToFile(plistPathInDocument + ".plist", atomically: true)
print("Item Added")
 print("plst  \(plistPathInDocument)")
