Question

so basically I have a UITableView and when using it to switch between other views some times going back to the main view the view I was just at gets “stuck”. The Bar at top switches to the right title and the back button disappears but the Tableview is now covered by the view I was just at. This only happens after about 10 times though of switching, anyhelp? thanks!

Error:

CoreAnimation: ignoring exception: *** Collection <__NSArrayM: 0x4e33140> was mutated while being enumerated.(
    "<Note: 0x4e0e520>",
    "<Note: 0x4e0d1b0>"
)

I should probably add that “Note” is just a NSObject

code for switching:
RootViewController.m

//create a string at the index of array where you clicked
    Note *note = [listOfItems objectAtIndex:indexPath.row];


    //Create view controller
    EditView *editView = [[EditView alloc]init];

    //Pass a long object
    [editView setNote:note];


    //Push, release
    [self.navigationController pushViewController:editView animated:YES];
    [editView release];

This code seems to be causing some issue, it’s basically to resave an object to an array with a added atribute. Its used with EditView.

-(void)viewDidDisappear:(BOOL)animated{
    for(Note *i in [Data sharedData].listOfItems){
        if (i == note) {
            i.info = infoField.text;

            [[Data sharedData].listOfItems replaceObjectAtIndex:[[Data sharedData].listOfItems indexOfObject:i] withObject:i];
            NSLog(@"%@",i);
        }
    }
}

I had similar issue. It was when I tried to mess up with animation UINavigationController apply to views. And it almost every-time was in popViewController. Check how you popping view controller, and try to avoid custom animation if you doing some.
