Question

I have a view that is used to update some NSUserDefaults. These defaults have an impact on a table in a different view. The issue I’m facing is that I want to reload the data in the table before the view is displayed again.

At present I have viewA which contains the table, I then display viewB using the following code:

[self presentModalViewController:viewB animated:YES];

Once the user has updated the NSUserDefaults viewB is dismissed, therefore displaying viewA again. Before viewA is displayed I want to be able to refresh the data though. Is there any way of doing this?

Answer 1

In viewA’s viewWillAppear call you refresh code.

-(void)viewWillAppear:(BOOL)animated{
     [super viewWillAppear:animated];
     // your refresh code
}
