1. If you want to make a conversation interface, slide to the bottom when you come in. 2, but after using the code that slides to the bottom, it doesn't slide to the bottom. It's always a short distance away. 3. It's not that there is a section at the bottom that can't slide up. It can slide up. That is, when you come in to this view, you can't directly slide to the bottom 4. This is my code
let indexPath = NSIndexPath(forRow: self.chatMessageModel.contentType.count-1, inSection: 0)
self.scrollToRowAtIndexPath(indexPath, atScrollPosition: .Bottom, animated: false)
5. This picture is what I look like after entering the conversation view
6. The red box in this picture shows that there is a small section below the tableview that has not been slid to the bottom
Q: who knows why?
