self.tableView reloadData not working in viewWillAppear

Question

I have an Xcode app that creates a tableview and then populates this with data from an sqlite database, this works perfectly and allows me to push data to a new view and delete etc,

This tableview is the first view loaded on a tab bar controller. The problem arises when i move to another view on the same controller, i.e. create an athlete, in this view i can add a new athlete to the database (which works fine) but when i go back to the tableview on the tab bar controller, the table is the same, i have to log out and log back in to see the change in the table,

I have tried [self.tableView reloadData] in the viewWillAppear function but this does nothing. I know that the function is getting called as i have placed an NSLog in their just for peace of mind.

I have found what i think may be the solution on here but i cant get it to work!

viewWillAppear, viewDidAppear not being called, not firing

i will post my code below and a screen shot of the storyboard as im convinced it is my poor way of setting up controllers that has caused this error. Any help would be much appreciated as i am now at the meltdown stage :D

-(void)viewWillAppear:(BOOL)animated {

//[super viewWillAppear:animated];

//[self.tabBarController viewWillAppear:animated];

[self.tableView reloadData];
NSLog(@"i just ran viewwillAppear");

}


- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

athleteObject *athObj3 = [athletes objectAtIndex:indexPath.row];

athleteIdDelete = athObj3.athId;

[self openDatabase];

[self deleteAthleteFromDataBase];

[athletes removeObjectAtIndex:indexPath.row];

[tableView reloadData];

}

reloadData works in my commitEditing function (this updates the tableview when i delete an entry via a swipe)

any help would be much appreciated, il post the screen shot below.

(cant figure out how to load a screenshot if its even possible)

Answer 1

It looks like athletes (a NSMutableArray I assume) is not being updated in viewWillAppear. Have you tried running the selector that populates the array from the database before calling reloadData?

Hope that helps!
