问题 When a certain Table View Controller displays for the first time, how to briefly show that the red “swipe to delete” functionality exists in a table row? The goal of programmatically playing peekaboo with this is to show the user that the functionality exists. Environment: iOS 11+ and iPhone app. Here's an image showing the cell slid partway with a basic "swipe to delete" red action button. A fellow developer kindly mentioned SwipeCellKit, but there’s a lot to SwipeCellKit. All we want to do

问题 I implemented a tableview with custom cells. The cells have their cornerRadius set to 2. Everything displays just fine until I enter edit mode.

问题 Frustrating fact: After calling tableView:moveRowAtIndexPath:toIndexPath: , tableView:cellForRowAtIndexPath: doesn't get called for that row. Call reloadRowsAtIndexPaths:withRowAnimation: after or before tableView:moveRowAtIndexPath:toIndexPath: within UITableView updates block also doesn't work: it raises Inconsistency error . I see 2 workarounds: delete+insert instead of move or do reload within another updates block. My question is: is there some other way to reload and move UITableView's

问题 I am new in ios development. When I use UITableView, I implement data source and delegate together. like the following two methods: // Data source method - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section // Delegate method - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath However, if I am understand correctly, table view does not hold any data, and it only store enough data to draw the rows that are currently
