I want to copy some files to specified folder by NSOpemPanel.
The source file is reading from XML and show to list in NSTable.
I can copy file by copyItemAtPath.
But now my app will turn to sandbox, then I can’t copy the file by copyItemAtURL.
How do I copy the file in sandbox mode?
I was looked over a lot of post. And I think the Security-scoped Bookmark may be a solution for this.
But I can’t create "Security-scoped Bookmark" from XML inside the path (the path was convert to NSURL ready).
I was setting to sandbox.entitlements but it's not clear this problem.
Is there any way for this?
Develop in macOS10.12 and Xcode8.3.3
Thanks
How do I copy the file in sandbox mode?
It is unclear what your current code is doing, but the rules under the sandbox are simple: To read or write a file located outside of an application's own container (which is hidden away under the Library folder) your application must either:
Use NSOpenPanel to obtain a URL from the user for the file path; or
Use NSOpenPanel to obtain a URL from the user for one of the ancestor folders of the file.
The second option gives access to a whole folder, including any sub-folders; i.e. the whole file/folder subtree rooted in the folder.
As you want to copy "some files" it sounds like asking the user for permission for the folder is appropriate. You can customise the NSOpenPanel to be a "request permission" dialog. If you are requesting a specific folder you can also have the dialog open in it's containing folder and only have the specific folder enabled for selection by the user.
Once you have the URL for the folder from NSOpenPanel you can create a security scoped bookmark for it and save that in your app's preferences or other configuration file (stored within the app's container). Doing this enables your app to regain access to the folder on subsequent executions without asking the user again.
If after investigating this issue and writing some code you hit an issue ask a new question, showing your code, and explaining the problem. Someone will undoubtedly help you with the next step.

(Once the hyperlink is created I will use it in OneNote to link to a file on my own Onedrive, for only me to use !)
When I view a file in Word online the URL displayed is:
https://onedrive.live.com/view.aspx?cid=53B31F7A44698440&resid=53B31F7A44698440%2130033&app=Word
Say I want to insert a link to the file in a website or OneNote page, such that it has NOT been shared with anyone. ie Only I have permissions to view it like the file reference by the above link.
Can I simply use the above URL as a link?
I have used OneDrive sharing, but I think all the methods given result in the file being shared with other named people or publically. eg like this one:
http://1drv.ms/1zOli6p
...which when viewed in word online shows this URL:
https://onedrive.live.com/view.aspx?cid=53B31F7A44698440&resid=53B31F7A44698440%2130035&app=Word
I have been experimenting and using the URL seems to work. However, if the above does work, what I don't get is why OneNote does not allow a link to be created to a file stored on Ondrive. (On my PC it sonly seems to allow links to locally stored files).
I have used GoogleDrive which allows you to select a file and right click it to "receive a link" which you can use in the manner described above. This is a really useful feature.
Note that in a similar way, I would like to create a link that causes onedrive to open and display a chosen folder. This seems to work ok when I use a URL this one that only I have permissions to view:
https://onedrive.live.com/?cid=53B31F7A44698440&id=53B31F7A44698440%2130031
Any advise is really appreciated.

The links you copy/paste from your browser's address bar should work just fine, as your experiments have confirmed. If you're not trying to share the content with other people, you don't need to go through the sharing flows. You can just use those URL's.
From within OneNote itself you can also get links to content by right-clicking on a page/section/notebook and clicking 'copy link to page,' 'copy link to section,' etc.
You can open folder in OneDrive online (via browser or right clicking on the folder in File Explorer then selecting "view online") and click "get link" at the top. Just cut and paste into OneNote. From there you can edit/rename the link as usual.
Oddly, OneNote has functionality to copy a FILE link using the Insert > Link, but you can't stop at the folder level.
Ideally, I'd like the above option as well as dragging a folder from OneDrive within Windows File Explorer and have it ask me if I want to copy the entire folder or create a link.
I use links in format
https://onedrive.live.com/edit.aspx?resid=fd5d9e0ac8248db7!3447 (example, not real link)
or
https://onedrive.live.com/?id=fd5d9e0ac8248db7!3447
where
fd5d9e0ac8248db7 - is your ID number, and
3447 - is ID number of element (folder, Word file, OneNote notebook, media etc.)
P.S. Link format for open .one files online and folders inside OneNote online:
https:/ /onenote.officeapps.live.com/o/onenoteframe.aspx?Fi=SDfd5d9e0ac8248db7!3447&H=emul&C=5_810_BN1-SKY-WAC-WSHI&ui=Ru-RU
(example, not real link)
where
https:/ /onenote.officeapps.live.com/o/onenoteframe.aspx?Fi=SD_____yourIDnumber___!___elementID____&H=emul&C=5_810_BN1-SKY-WAC-WSHI&ui=Ru-RU
OneDrive has a "Copy link" function in a few places that you would think does what it states. However, as soon as you select "Copy link", a share is created with the defaults of your OneDrive (which could be your organisation's). In my case, the default is share with editing permissions. This is probably the last thing you would expect when you are requesting to "Copy link". This is really quite dangerous, since the now shared link could be used by anybody if it subsequently forwarded to others.
Why would you want to copy a link? My use case is that I have a folder shared as read only with specific people. I want to give them a link to a sub-folder or file that they already have access to, but I do not want to create new permissions, that in my case give editing to anybody with the link!
It seems that the way to properly "copy a link" (literally) is as suggested ie copy the URL from the address bar.

I know that it is possible to use UIDocumentInteractionController to give the user a chance to open a document, say a Word document, in an application such as Pages.
Is it possible in any way to do the reverse: that is, allow a user to save the document back to an area where my application can access the newly saved document, or to provide a 'save to' option within Pages? Like how Dropbox integrates with Pages.
Thanks
Unfortunately no. Apps that support Dropbox do so by implementing the Dropbox API and syncing to the Dropbox server when online. The only way another app can give a file to your app directly is through the UIDocumentInteractionController "Open in.." feature. You can sign up for receiving files of the formats you want to support like this: those files will be written temporarily in your app bundle's Documents/Inbox and you will have to save them in another directory to be able to write to them.
This is not possible. You can't save apps to other application's space due to required app sandboxing.
I am working on silverlight application and I want to save my file in a particular folder through savefile dialog box. But I am not able to save it.
And also I want to open it, let's say through open - dialog box.
How can I do it?
Thanks..
You can open/save files using the open/save file dialogs even outside the isolated storage for the application. Search "silverlight savefiledialog" and you'll find many examples.
