Toolbars are used to present a set of functions to a user. You will see these at the bottom of iPhone apps and generally give you the option to do things like edit files, send email or take a picture.
Using UIToolbar in Your iPhone Apps
Today, I am going to show you how to use UIToolbar in your iPhone apps. Essentially, what you need to do is to create an instance of UIToolbar, add buttons to it and then add the toolbar to your view. Usually, you will also need to assign actions to each toolbar button as well.
Here is video of how to use UIToolbar taken from my own code library that I ship with my ebook:
Source Code for Using UIToolbar
#import "Toolbar.h"
@implementation Toolbar UILabel *label; UIToolbar *toolbar;
-(void)viewDidLoad {
[super viewDidLoad];
//Create label
label = [[UILabel alloc] init];
label.frame = CGRectMake(10, 10, 300, 40);
label.textAlignment = UITextAlignmentCenter;
label.text = @"Press Button";
[self.view addSubview:label];
[label release];
//create toolbar using new
toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleDefault;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 410, 320, 50);
//Add buttons
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self
action:@selector(pressButton1:)];
UIBarButtonItem *systemItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction
target:self
action:@selector(pressButton2:)];
UIBarButtonItem *systemItem3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:self
action:@selector(pressButton3:)];
//Use this to put space in between your toolbox buttons
UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
//Add buttons to the array
NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem, systemItem2, flexItem, systemItem3, nil];
//release buttons
[systemItem1 release];
[systemItem2 release];
[systemItem3 release];
[flexItem release];
//add array of buttons to toolbar
[toolbar setItems:items animated:NO];
[self.view addSubview:toolbar];
}
//Action methods for toolbar buttons:
-(void) pressButton1:(id)sender{
label.text = @"Add";
}
-(void) pressButton2:(id)sender{
label.text = @"Take Action";
}
-(void) pressButton3:(id)sender{
label.text = @"Camera";
}
-(void)dealloc {
[toolbar release];
[label release];
[super dealloc];
}
@end

Thanks so much

WoW!!! Great, thank you
Excellent – just what I was looking for – sample code that is obscured by an advert. I hate it when tutorials are clear, concise, and helpful, and it can be difficult to find a tutorial page that is a cock-up, I've been looking for ages for something written by somebody to bloody lazy to view their own layout, and I'm delighted to say I've found it !. Perhaps you could also do a set of tutorials full of spelling mistakes and code errors, that would be a terrific service.
… sounds like Learner was having a difficult day; the sarcasm is so thick I can barely see the web page.
