If you have PDFpen running on your Mac and PDFpen on your iPad or iPhone, please be aware of what updating to iOS 8’s new iCloud Drive will mean for you — no more syncing with your Mac until Yosemite (OS X 10.10).
Macworld already has a good article on this topic, check it out for more details.
When you update your iPhone or iPad to iOS 8, you are offered the option to update to the new iCloud Drive. If you do, all your iCloud documents are transferred from the old iCloud to the new iCloud Drive. However, this means files on your iOS 8 device can no longer use iCloud to sync with files on devices running iOS 7 or Mavericks, they can only sync with iOS 8 and Yosemite devices. Yosemite is not expected to release until later this year.
Essentially, the iCloud of iOS 7 and Mavericks (OS X 10.9) is a different “cloud” than the new iCloud Drive of iOS 8 and the upcoming Yosemite, and those two clouds don’t talk to each other.
If you have updated to iOS 8 and the new iCloud Drive, you can still sync your documents in PDFpen using Dropbox. In PDFpen for Mac, simply store your files in a Dropbox folder. In PDFpen for iPhone or iPad add that same Dropbox folder as a sync folder.
Adding a Synchronized Folder:
- Tap “Documents”, or the folder title or icon presently displayed in the navigation bar. A menu appears.
- Tap “Edit Sync Folders” and select Dropbox as your sync service and login.
- In the following navigation dialog select a folder for synchronizing then tap “+ Sync Folder”.
Set this folder to sync its contents automatically by choosing Tools > Settings > Dropbox and switching on “Automatically Sync.”
Navigate into and out of this new folder by tapping the folder title or icon displayed in the navigation bar.
More details are available in the “Synchronized Folders with Dropbox” section of the in-app Help.
