In Following code i added two UIBarButton with flexSpace..
you can add UIBarButton as you want
UIToolbar *Toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
Toolbar.barStyle = UIBarStyleBlackTranslucent;
[Toolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
[flexSpace release];
UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(Cancel)];
[barItems addObject:btnCancel];
UIBarButtonItem *btnDone = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(done)];
[barItems addObject:btnDone];
[Toolbar setItems:barItems animated:YES];
