(...) The most obvious difference about iCloud Drive on iOS is that because there is no Finder equivalent, there is no in-built app to view all your iCloud Drive files and folders like you can on OS X Yosemite. To resolve this problem, apps on iOS can implement the iCloud Drive Document Picker which will provide a popup window that gives you access to the full iCloud Drive. One such example of an app that implements the iCloud Drive Document Picker is Readdle's PDF Expert.

The Messy Solution that is iCloud Drive

There's little doubt that iCloud Drive is an improvement over its predecessor, Documents in the Cloud. Implementing the Document Picker system, which allows a user to access files that have been created in other apps, is a much needed improvement. But there are some fundamental flaws with iCloud Drive and they are quite fundamental in my opinion. Apple's decision to avoid using a traditional 'file system' may have made iOS simple to use, but it has also made iOS maddening to use for those who want to take full advantage of the platform.

iCloud Drive sits awkwardly as a solution to a problem that Apple created. Apple at first tried to avoid implementing a file system on iOS but have now realised that some users need it and have created iCloud Drive in a way that tries to hide what is ostensibly a file system, ultimately making it more complicated. The problem is that files still get stuck in these weird app folders, which frankly makes no sense to me. If I have multiple text editors or spreadsheet apps, how am I supposed to know which app I created the file in?

In my opinion, Apple should get rid of these weird app folders and simply save files to the root of iCloud Drive, or into user-created folders if the user chose. To simplify things, apps such as Pages which can only view certain document formats would only need to display those files which it could open. This way, there is no file system unless the user creates one and iOS only displays the documents relevant to the particular app being used. No need to hunt around in the dozens of app folders to find that one file you were looking for. Surely that would be simpler?

Wie kommt man denn in diese Ansicht auf dem iPhone, wie hier auf der Apple Homepage dargestellt:

Das ist doch keine App eines Drittanbieters?!!

Documents by Readdle ... Stürzt immer wieder ab. (iPhone 5)
Kein Vergleich mit Dropbox und Co.

PDF Expert von Readdle funktioniert einwandfrei! (unterschiedliche iDevices)

Diese Ansicht erhält du wenn du auf dem iPhone z.B. Pages öffnest und dann auf das + tippst und die iCloud auswählst. Grundsätzlich muss die App iCloud Drive unterstützen.

Aber erst ab Version 5, ich habe noch eine 4er damit gehts nicht.
