【问题描述】:
我正在尝试将文件保存在 Documents 目录的子文件夹中,但它不会保存。我似乎无法找到问题所在。这是我尝试过的:
if let audioUrl = NSURL(string: "http://pillar.foundationu.com/wp-content/plugins/pillar-data-sync/php/htmlBreakdownResult.json") {
let documentsUrl = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
do {
let directoryContents = try NSFileManager.defaultManager().contentsOfDirectoryAtURL(documentsUrl, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions())
print(directoryContents[0].path!)
if NSFileManager().fileExistsAtPath(String(audioUrl.path!)) {
print("The file already exists at path")
} else {
// if the file doesn't exist
// just download the data from your url
if let myAudioDataFromUrl = NSData(contentsOfURL: audioUrl){
// after downloading your data you need to save it to your destination url
if myAudioDataFromUrl.writeToURL(NSURL(fileURLWithPath: directoryContents[0].path!), atomically: true) {
print("file saved")
} else {
print("error saving file")
}
}
}
} catch let error as NSError {
print(error.localizedDescription)
}
}
这是我要保存文件的位置:
/Users/rendell/Library/Developer/CoreSimulator/Devices/5A052CC5-FD34-44FD-B060-24D6F1970860/data/Containers/Data/Application/37753B0B-FAB0-478D-A7F8-98E3039D07DD/Documents/MyFolder2
但它一直给我“错误保存文件”。
