CFURLCopyResourcePropertyForKey失败，因为传递的URL没有方案 [英] CFURLCopyResourcePropertyForKey failed because passed URL no scheme

问题描述

我有一个程序可以将文件保存到iCloud，这对iOS7很有用，但现在我在iOS8上遇到这个错误，似乎无法找到解决方法。还有其他人有这个问题吗？任何想法都将非常感激。

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.

错误：
CFURLCopyResourcePropertyForKey失败，因为它传递了这个没有方案的URL：/ var / mobile / Containers / Data / Application / ASFHDDE3-B1BB-41D7-A47C-DCC328362W21 / Documents / mypictostore.png

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

代码行引发错误：
[fileManager setUbiquitous：YES itemAtURL：backupUrl destinationURL：[[ubiq URLByAppendingPathComponent：@DocumentsisDirectory：true] URLByAppendingPathComponent：backupName] error：& theError];

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

网址：
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

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

谢谢你，

推荐答案

对我来说，通过添加

file://

就在文件路径地址之前，如下所示：

right before the file path address like this:

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