Question

I’m searching for a way to have a UITableViewController with a UITableView at the top and a UIPickerView bellow (with fix position).

I’ve found a solution for fixing the picker with the code bellow:

- (void)viewDidLoad {
    [super viewDidLoad];

    _picker = [[UIPickerView alloc] initWithFrame:CGRectZero];
    _picker.showsSelectionIndicator = YES;
    _picker.dataSource = self;
    _picker.delegate = self;

    // Add the picker to the superview so that it will be fixed
    [self.navigationController.view addSubview:_picker];

    CGRect pickerFrame = _picker.frame;
    pickerFrame.origin.y = self.tableView.frame.size.height - 29 - pickerFrame.size.height;

    _picker.frame = pickerFrame;

    CGRect tableViewFrame = self.tableView.frame;
    tableViewFrame.size.height = 215;

    self.tableView.frame = tableViewFrame;

    [_picker release];
}

The problem is with the tableview, it seems resizing doesn’t work so I can’t see all results .

Thanks for your advice.

You should use a UIViewController subclass instead of UITableViewController to manage a table view if the view to be managed is composed of multiple subviews, one of which is a table view. You can add a UITableView subview and make your controller implement UITableViewDelegate and UITableViewDataSource protocols.

The default behavior of the UITableViewController class is to make the table view fill the screen between the navigation bar and the tab bar (if either are present).

From Table View Programming Guide for iOS:

Note: You should use a
UIViewController subclass rather than
a subclass of UITableViewController to
manage a table view if the view to be
managed is composed of multiple
subviews, one of which is a table
view. The default behavior of the
UITableViewController class is to make
the table view fill the screen between
the navigation bar and the tab bar (if
either are present).

If you decide to
use a UIViewController subclass rather
than a subclass of
UITableViewController to manage a
table view, you should perform a
couple of the tasks mentioned above to
conform to the human-interface
guidelines. To clear any selection in
the table view before it’s displayed,
implement the viewWillAppear: method
to clear the selected row (if any) by
calling deselectRowAtIndexPath:animated:.
After the table view has been
displayed, you should flash the scroll
view’s scroll indicators by sending a
flashScrollIndicators message to the
table view; you can do this in an
override of the viewDidAppear: method
of UIViewController.
