I’m a new for iphone.
I saw some document for iphone develop, but
I don’t understand the [xxx reloadData]; with tableView yet.
When i use this method, my all cells are cleared.
What happened?
I don’t understand it.
It means you force the
UITableViewto get the data and refresh itself. It is what you wanna do after you changed something in your data source.For example, I have a
NSMutableArrayof three objects a, b and c. I have a button to delete an object, say b. After I pressed my button and get object b deleted from my array, my table view won’t reload unless I call[myTableViewName reloadData]to force it refresh itself.If after you do
[xxx reloadData], you got nothing. It means, your data needed for the table view is not there anymore. So track the data source and see if the data got changed.
