Swift 3 文件复制错误

Question

我正在尝试将 .plist 的副本复制到 Documents 文件夹中。 我有这段代码，但我收到“文件复制错误”。

let srcPath = Bundle.main.path(forResource: "Gameboard", ofType: "plist")
//let path = Bundle.main.resourcePath!
let path = String(describing: FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first)
print(srcPath)
print(path)
do {
    //Copy the project plist file to the documents directory.
    try FileManager.default.copyItem(atPath: srcPath!, toPath: path)
} catch {
    print("File copy error!")
}

Answer 1

Documentation :

dstPath
The path at which to place the copy of srcPath. This path must include the name of the file or directory in its new location. This parameter must not be nil.

您需要将文件名“Gameboard.plist”附加到目标路径:

let srcUrl = Bundle.main.url(forResource: "Gameboard", ofType: "plist")
let documentsUrl = FileManager.default.urls(
    for: .documentDirectory,
    in: .userDomainMask
).first!
let destinationUrl = documentsUrl.appendingPathComponent(
   "Gameboard.plist",   // or srcUrl.lastPathComponent
    isDirectory: false
)

do {
   try FileManager.default.copyItem(at: srcUrl, to: destinationUrl)
} catch {
   ...
}
