Add UIBarButtonItem to UIToolbar programmatically?

Here's what I need.

I have a free version and a paid version of my app. When the paid version loads, I need 3 UIBarButtons on my UIToolBar. When the Free version loads I need 4 UIBarButtons. On the far right barButton, I need the tint Blue, while the rest are default black. And I'm assuming the flexible space between them to even them out. I've tried doing this through IB, but I can't seem to get it to work with the spacing correct. As you can see, the bottom toolbar with 3 buttons are not spaced evenly with the toolbar. (I would like to do this programmatically)

enter image description here

enter image description here

#ifdef LITE_VERSION


#else

[buyButton removeFromSuperview];

#endif

Add the buy button to your toolbar by default, and tag it with some unique value (say -1), and then at runtime you can remove it from the toolbar like so:

#ifdef LITE_VERSION
    //Dont need to do anything, view is set up as lite version by default
#else

    NSArray *elements = toolBar.items;
    NSMutableArray *newElements = [[NSMutableArray alloc] initWithCapacity:[elements count]];

   for ( UIBarItem *item in elements )
   {
        if ( item.tag != -1 )
        {
            //Item is not the buy button, add it back to the array
            [newElements addObject:item];
        }
    }

    [toolBar setItems:newElements];

#endif

This is some code I use in one of my apps already to replace an item that is tagged in IB with -1 with a specific button at runtime, depending on which view is on display

UIToolbar* toolbar = [[UIToolbar alloc]
                  initWithFrame:CGRectMake(0, 0, 320, 45)];
[toolbar setBarStyle: UIBarStyleBlackOpaque];

// create an array for the buttons
NSMutableArray* BarbuttonsArray = [[NSMutableArray alloc] initWithCapacity:5];

// create a clearAll button
UIBarButtonItem * clearAllButton = [[UIBarButtonItem alloc] initWithTitle:@"Clear All" 
                             style:UIBarButtonItemStylePlain
                             target:self
                             action:@selector(clearAllAction:)];

clearAllButton.style = UIBarButtonItemStyleBordered;
[BarbuttonsArray  addObject:clearAllButton];
[clearAllButton release];


 // create a calculate button
 UIBarButtonItem *calculateButton = [[UIBarButtonItem alloc]initWithTitle:@"Calculate" 
                             style:UIBarButtonItemStylePlain
                           target:self
                           action:@selector(calculateButton:)];
calculateButton.style = UIBarButtonItemStyleBordered;
[BarbuttonsArray  addObject:calculateButton];
[calculateButton release];


// create a settingButton
UIBarButtonItem *settingButton = [[UIBarButtonItem alloc]initWithTitle:@"Setting" 
                             style:UIBarButtonItemStylePlain
                             target:self
                             action:@selector(settingButton:)];
settingButton.style = UIBarButtonItemStyleBordered;
[BarbuttonsArray  addObject:settingButton];
[settingButton release];


 // create a buyNowButton

UIBarButtonItem *buyNowButton = [[UIBarButtonItem alloc]initWithTitle:@"Buy Now" 
                             style:UIBarButtonItemStylePlain
                          target:self
                          action:@selector(buyNowButton:)];
buyNowButton.style = UIBarButtonItemStyleBordered;
[BarbuttonsArray  addObject:buyNowButton];
[buyNowButton release];


 // put the BarbuttonsArray in the toolbar and release them
[toolbar setItems:BarbuttonsArray  animated:NO];
[BarbuttonsArray  release];

// place the toolbar into the navigation bar
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];
[toolbar release];


//before using these lines of code you have to alloc and make the property of   UINavigationController in your appDelegate

Try to use this may help you

First add buy button on your toolbar. bind and synthesize.

if(AppPaid) { 
    NSMutableArray *items = [YourToolBar.items mutableCopy];
    [items removeObject:yourBuyButton];
    YourToolBar.items = items;
    [items release];
  }
