The SDK saves OAuth tokens in standardUserDefaults, and if the user wants to disable the Dropbox functionality the OAuth tokens have to be removed (otherwise the SDK finds them and goes off to work). Here's the weird part: whether I...
For example: NSString *strWord = "english"; The result NSArray would be something like: e n g l i s h I think is possible to do it with [NSString componentSeparatedByCharacter:somecharacter], but I don't know what that character is...
