Question

This is driving me insane! (ios 5+, ARC)

Pretty simple concept here:
I have a UIView with an embedded UITableView, when clicking on a specific cell, I have iOS launch a modalview with a segue.
This modalview, is a UIView with an Embedded UITableView in it, filled with names from a data source. You can choose multiple items in this view (using cellaccessory: checkmark)

The Goal
Get some sort of “Done” button to show up

Ok, so after much running around, I am to understand that Modal windows do not, in fact, allow navigationController items. No toolbars, no Navigationbars by default.
Ok, so I’ll create my own.

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSInteger tbHeight = 50;
    UIToolbar *tb = [[UIToolbar alloc] initWithFrame:CGRectMake(0, (self.view.frame.size.height - tbHeight), self.view.frame.size.width, tbHeight)];
    tb.translucent = YES;

    UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(doneAction:)];

    NSArray *barButton  =   [[NSArray alloc] initWithObjects:flexibleSpace,doneButton,nil];
    [tb setItems:barButton];


    [self.view addSubview:tb];

    barButton = nil;

    //....

}

Simple enough right?

Well, the toolbar does show up, for sure. BUT, it doesnt stick to the bottom like its supposed to. In fact, when you scroll the embedded tableview up and down, the UIToolbar goes with it, almost like its stuck on the tablevie somehow.

Ive been looking for hours for solutions, I’ve come across nothing. Wondering if anybody here has any ideas?

If you need more information, please by all means, enquire 🙂

It’s strange that your toolbar is scrolling with the table if it’s a UIViewController subclass, unless you’ve assigned a UITableView to self.view or something… But since it is, this is what I do when adding a fixed item to a table view:

-(void) scrollViewDidScroll:(UIScrollView *)scrollView {

    tb.frame = CGRectMake(0, self.view.bounds.size.height-tb.bounds.size.height+scrollView.contentOffset.y, self.view.bounds.size.width, tb.bounds.size.height);

}
