UITableView reload data

Question

i'm making a navigation based application for iphone.

one of my view controllers looks like this:

@interface NewComputerViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> 

so i'm using a UITableView to show data.

when the view loads, I use a button in the top navigation bar to run a function loadStuff load some stuff in a Dictionary.

My question: how do I repopulate the table view in that viewcontroller from that loadStuff function (which belongs to the view controller)

Answer 1

You can always use [tableView reloadData] method!

But if you have some data stored locally and loading new stuff from some server then you can go for:

[tableView beginUpdates]; [tableView insertRowsAtIndexPaths:*arrayOfIndexPaths* withRowAnimation:*rowAnimation*]; [tableView endUpdates]; 

And if you want to delete existing row you can use

[tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:*arrayOfIndexPaths* withRowAnimation:*rowAnimation*]; [tableView endUpdates]; 

Answer 2

Try using [tableView reloadData]; (where tableView is the name of your instance variable)
