Add UIBarButtonItem to UIToolbar programmatically? - iphone

Question

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)
#ifdef LITE_VERSION
#else
[buyButton removeFromSuperview];
#endif

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

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];
}

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
