更新UITableView中的所有单元格

Question

I have a method that I want to run on every cell in my UITableView, which would update a property in each cell (and the display would consequently reflect the change). How can I do this?

Answer 1

The "cell" shouldn't really hold any information so you don't really update a cell.

You update the data model (ie the array or whatever) that you are using to store data that then gets displayed in the table.

Then when you want to "update the cells" you just update the data model data and then reload the table with...

[self.tableView reloadData];
