When I want to write dataFile with method - (DBFile *)createFile:(DBPath *)path error:(DBError **)error;, always warning that "app is not allowed to create file:xx". Does anyone knows?
- (DBFile *)createFile:(DBPath *)path error:(DBError **)error;
This most likely means your app has "file type" permission, and the file type you picked doesn't include the extension of the file you're trying to write. You can check your app's permissions via the https://www.dropbox.com/developers/apps.
