Question

I’m developing a small application. I need to create three buttons in a subclass. One button is add, another one is search and the last one is back. I also create left and right buttons. But I can’t create search button in the center of the navigation bar. How can I create it? My code is:

- (void)viewDidLoad 
{
[super viewDidLoad];
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc] initWithTitle:@"Flip"                                            
                                   style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(flipView)];
self.navigationItem.rightBarButtonItem = flipButton;
[flipButton release];

UIBarButtonItem *flipButtons = [[UIBarButtonItem alloc] 
                               initWithTitle:@"Add"                 
                               style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(addbuttonview)];
self.navigationItem.leftBarButtonItem = flipButtons;
[flipButtons release];

}

How to create a middle button in the navigation bar? Please help me.

Below is the code to use segment control in navigation bar programatically

NSArray* arr = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"Log_Button.png"], [UIImage   imageNamed:@"Chart_Button.png"], nil];
segmentedControl = [[UISegmentedControl alloc] initWithItems:arr];
[segmentedControl addTarget:self action:@selector(action)   forControlEvents:UIControlEventValueChanged];
[segmentedControl setSegmentedControlStyle:UISegmentedControlStyleBar];
[arr release];
UIBarButtonItem *rb = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[self.navigationItem setRightBarButtonItem:rb];
[rb release];
