使用 iOS 9 我试图使用NSFileManager'smoveItemAtURL：
do {
print(localURL) // http://localhost:3000/api/v1/activities
print(cacheFile) // file:///Users/kyledecot/Library/Developer/CoreSimulator/Devices/35C03988-D8F5-42E5-AB35-B99BE461EEAE/data/Containers/Data/Application/69593B3A-F764-4BC3-89AD-72B701BF85C8/Library/Caches/activities.json
try fileManager.moveItemAtURL(localURL, toURL: cacheFile)
} catch let error as NSError {
print(error)
}
When catching the error I'm getting:

I've already added the appropriate values to my Info.plistto ensure that ATS is happy (see screenshot). What's odd is that I am able to download the data from my local server using HTTP (via dataTaskWithRequest:) but NSFileManager then complains about the same URL when trying to perform moveItemAtURL.
我已经为 my 添加了适当的值以Info.plist确保 ATS 满意（请参见屏幕截图）。奇怪的是，我能够使用 HTTP（通过dataTaskWithRequest:）从本地服务器下载数据，但是 NSFileManager 在尝试执行moveItemAtURL.

There are two things to know here:
这里有两件事需要了解：
In iOS 9, by default,
http://is not supported. You must communicate securely (withhttps://). You can turn off this feature in your Info.plistif you have to.NSFileManager URLs must be paths to files on disk — that is, they must be fileURLs. Yours is not; it's an
http://URL. If your goal is to download a file and then copy it somewhere, use NSURLSession's download task.
在 iOS 9 中，默认情况下
http://不支持。您必须安全地（与https://）通信。如果需要，您可以在Info.plist 中关闭此功能。NSFileManager URL 必须是磁盘上文件的路径——也就是说，它们必须是文件URL。你的不是；这是一个
http://网址。如果您的目标是下载文件然后将其复制到某处，请使用 NSURLSession 的下载任务。
