UISplitView controller toolbar not showing in detail view

[nothingatall]

Hi guys, I have set up a UISplitView controller which deals with multiple detail views programmatically. This is based on the apple example here

However I am having major issues with getting the toolbar to show up in any of my detail views (and thus the popover)! I get the idea that I am not initializing and adding it to the view correctly (if at all) but none of my attempts are working!

If someone could give me some thoughts/advice/help etc that would be reallyREALLY handy! I have added some code below (yes, I know it is messy.. and well... like I say, I'm really unsure on the way to do this!).

Apologies, I'm not the best person at this iOS programming malarky(!)

CategoriesViewController_iPad.h

#import <UIKit/UIKit.h>
#import "RootViewController_iPad.h"

@interface CategoriesViewController_iPad : UITableViewController <SubstitutableDetailViewController>
{
	UIToolbar *toolbar;    
}
	
@property (nonatomic, retain) UIToolbar *toolbar;
	
@end

CategoriesViewController_iPad.m

@synthesize toolbar;

#pragma mark -
#pragma mark - View lifecycle
- (void)viewDidLoad
{
    [super viewDidLoad];
	
	[self.tableView initWithFrame:self.tableView.frame style:UITableViewStylePlain];
	self.navigationItem.title = NSLocalizedString(@"Categories", @"DetailView Categories");
	self.view.backgroundColor = [UIColor orangeColor];

	[self.view addSubview:toolbar];
	
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
	self.navigationController.toolbarHidden = NO;
	self.navigationController.toolbar.barStyle = UIBarStyleDefault;
}

- (void)viewDidUnload
{
	[super viewDidUnload];
	self.toolbar = nil;
}

Well, your toolbar isn't an IBOutlet, so it's not being initialized with any XIB. Therefore, most likely it is nil and has no frame (as I recall, the default value for floating-point values in undefined…but I may be mistaking that for something else).

Try this:

- (void)viewDidLoad {
    // Other setup
    if (!self.toolbar) {
        // Retain property—don't use setter to maintain +1 retain count from init
        toolbar = [[UIToolbar alloc] initWithFrame:someCGRectForToolbar];
        // Other setup for toolbar properties (style, tint)
    }
    [self.view addSubview:self.toolbar];
}
