self.tableview reloadData causing crash in UITableView

I'm getting this crash when selecting a row: '-[__NSCFArray objectAtIndex:]: index (1) beyond bounds (1)',

I moved the data out of the viewWillAppear because we though it was causing a crash. I now have it loading on ViewDidLoad.

However if the [self.tableview reloadData]; is on, I get this crash.

Ideas?

  -(void) lo开发者_Go百科adData3;{

    MyAppDelegate *AppDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
self.tableDataSource3 = [AppDelegate.data3 objectForKey:@"Rows"];
NSLog(@"AppDelegate.data3 : %@",AppDelegate.data3 );
NSLog(@"self.tableDataSource3 : %@",self.tableDataSource3 );

}

- (void)viewDidLoad {
    [super viewDidLoad]; 
    [self loadData3];
    if(CurrentLevel3 == 0) {
    self.navigationItem.title = @"Families I Follow";
}
else 
    self.navigationItem.title = CurrentTitle3;  
}
}


-(void)viewWillAppear:(BOOL)animated {
        [super viewWillAppear: animated];
            [self.tableview reloadData];
}

More than likely, you are changing the Array that loads the UITableView while it is being displayed, so when you click on a Row the row no longer exists in the Array. Therefore, the out of bounds error on the Array.

 - (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [self.tableView reloadData];
}

Moving reloadData to viewDidAppear solves this issue.

Since its happening while selecting a row, the error is most likely in your tableView:didSelectRowAtIndexPath: or tableView:willSelectRowAtIndexPath: method(s). Nothing seems intrinsically wrong with the viewWillAppear: code fragment that you've posted.
