How can I use UIDocumentPickerViewController to let the user select a folder from their Dropbox?
If I call this, I can browse for folders, but the Dropbox folder is greyed out:
[[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[(__bridge NSString*)kUTTypeFolder]
inMode:UIDocumentPickerModeOpen];
If I change the mode to UIDocumentPickerModeImport, I get an Assertion failure and it crashes. It seems that Import doesn't work together with kUTTypeFolder. If I keep Import and set the types to @[kUTTypeFolder, kUTTypeImage], I get access to the Dropbox, but the picker only lets me select images, not folders.
Any help or advice would be appreciated!
The Dropbox iOS app document picker doesn't support opening folders, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
