Hi,
I had a simple implementation of DBChooser in my iPad app, and it worked fine up until the moment I upgraded my device and SDK to iOS 9.
What happens now is:
1) My app launches DBChooser (DBChooserLinkTypeDirect)
2) Dropbox appears
3) I pick my file
4) I get a 'Generating Link' message
5) I remain in the DropBox app instead of being returned to my app. openURL: is never called
I have set all of the URL schemes, and there are no syslog errors generated and, like I said, it used to work just fine.
I've tried all sorts of solutions, including creating brand new test apps that do nothing but fire up DBChooser. On one occasion, I created a completely new Xcode app, and a brand new DropBox app that used a new key, and the behavior changed slightly. This time, DropBox launched my app after I selected the file (openURL: was called in my app), and then DropBox was immediately launched over the top of my app again. This behavior happened 3 times in a row, and on the 4th (with no changes to the code or app setup), it went back to simply not exiting DropBox at all.
I've uninstalled DB and reinstalled it several times, written test apps, and gone over the docs with a fine tooth comb, but I simply can't get it behaving like it used to in iOS 8, which leads me to suspect the root cause is something to do with the new iOS 9 security stuff that went in. I've read reports from the iOS 9 beta that due to an iOS bug, openURL: had the extra security schemes that canOpenURL: now has, which might cause problems. openURL: should function as it used to in previous SDKs, according to Apple.
Can anybody shed some light on this? Has anybody else seen similar behavior?
Cheers,
Matt.
