uitableview

问题 I'm having troubles with my UITableView in swift on Xcode 6 : I would like my UITableView cells to fade in / out when appearing / disappearing. I looked a lot on the web for fade animations but I didn't find what I wanted because it's based on duration animations. I Think what I need is sort of mask based on alpha ? I'm not sur and I don't even know have to create one... I have a UIViewController containing a tableView and some blank space (for now) upside and downside of the UITableView.

问题 How can I get the second cell to expand to fit the text rather than scaling the text? Is there a built in way of doing this in iOS or will I have to come up with some home-cooked solution? If you look in the iOS Contacts application, there's a box like this for Address. I can't find how to implement this though. For anyone looking to achieve this in future, here's the code for my solution: HEADER file: #define FONT_SIZE 22.0f #define CELL_CONTENT_WIDTH 320.0f #define CELL_CONTENT_MARGIN 5.0f

问题 This should be simple enough. I have an iPhone app with a TableView. How do I add the little classic arrow to the righthand side of each cell? 回答1: Just set the respective accessoryType property of UITableViewCell . cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; In Swift 3 , cell.accessoryType = .disclosureIndicator 回答2: You can do this in Interface Builder. Simply click click on the Table View , go to Prototype Cells on the right side and make it 1. Then click that
