Question

how do I add by code on a button to a toolbar that I have the property?

@property (strong, nonatomic) IBOutlet UIToolbar *toolB;

Answer 1

UIBarButtonItem *buttonOne = [[UIBarButtonItem alloc] initWithTitle:@"Button One" style:UIBarButtonItemStyleBordered target:self action:@selector(action)];

UIBarButtonItem *buttonTwo = [[UIBarButtonItem alloc] initWithTitle:@"Button Two" style:UIBarButtonItemStyleBordered target:self action:@selector(action)];

NSArray *buttons = [NSArray arrayWithObjects: buttonOne, buttonTwo, nil];
[toolBar setItems: buttons animated:NO];

Will do the trick if i understand correctly what you are asking. action being the method you want the buttons to call.
