CFURLCopyResourcePropertyForKey failed because pas

问题:

I have a program that saves a file to the iCloud and this has worked great for iOS7, but now I get this error with iOS8 and cannot seem to find the answer on how to fix it. Anyone else had this problem? Any ideas would be greatly appreciated.

The Error: CFURLCopyResourcePropertyForKey failed because it was passed this URL which has no scheme: /var/mobile/Containers/Data/Application/ASFHDDE3-B1BB-41D7-A47C-DCC328362W21/Documents/mypictostore.png

The Line of Code Throws Error: [fileManager setUbiquitous:YES itemAtURL:backupUrl destinationURL:[[ubiq URLByAppendingPathComponent:@"Documents" isDirectory:true] URLByAppendingPathComponent:backupName] error:&theError];

URLS: destinationURL: file:///private/var/mobile/Library/Mobile%20Documents/ABC23455~MY-Program/ backupUrl: /var/mobile/Containers/Data/Application/ASDFGEEW-B1BB—6FR6-A47C-DCCF21876D36/Documents/mypic.png

Thank you, Jon

For me this problem was fixed by adding

file://

right before the file path address like this:

var filePath = "file://\(fileURLpath)"


回答2:

Or maybe you can use NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("mypictostore", ofType: "png")!) instead of using NSURL(string: NSBundle.mainBundle().pathForResource("mypictostore", ofType: "png")!)

Older Swift version answer:

var str:String = "/var/mobile/Containers/Data/Application/3039975A-5E05-4A4C-8000-55C681A7C35F/Documents/index.html"

var url:URL = URL.init(fileURLWithPath: str)

Swift 4 Answer:

var str:String = "/var/mobile/Containers/Data/Application/3039975A-5E05-4A4C-8000-55C681A7C35F/Documents/index.html"

var url:URL = URL(string: str)!

look, I find this,The url is The location to write the data into. we should tell the system a file path.

  • var filePath = "file://(fileURLpath)"
  • var url:URL = URL.init(fileURLWithPath: fileURLpath)
