How to add several UIBarButtonItems to a NavigationBar?

Question

I want to draw multiple buttons on a UINavigationBar. These will be either on right side or left side.

Answer 1

I did one example in which I had two buttons ( i.e. Edit and +) on Right side of NaviagationBar.

1) You have to create one NSMutableArray(i.e. "buttons" in example) and add UIBarButtonItem (i.e. bi1 and bi2 in example) to the NSMutableArray (i.e. buttons).

2) Add NSMutableArray(i.e. buttons in example) to toolbar(i.e. UIToolbar *tools in example).

3) Add toolbar to NavigationBar.

 NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:2];
 UIToolbar *tools = [[UIToolbar alloc]
                    initWithFrame:CGRectMake(0.0f, 0.0f, 90.0f, 55.01f)];
// Add bar button1.

UIBarButtonItem *bi1 = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(Edit:)];
bi1.style = UIBarButtonItemStyleBordered;
bi1.width = 45;
[buttons addObject:bi1];
//[bi1 release]; Do not release if ARC enabled.

// Add bar button2.
UIBarButtonItem *bi2 = [[UIBarButtonItem alloc] initWithTitle:@"+" style:UIBarButtonItemStylePlain target:self action:@selector(Add:)];
bi2.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi2];
//[bi2 release]; Do not release if ARC enabled.

// Add buttons to toolbar and toolbar to nav bar.
[tools setItems:buttons animated:NO];
//[buttons release];  Do not release if ARC enabled.

 // Add toolbar to nav bar.
UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
self.navigationItem.rightBarButtonItem = twoButtons;
//[twoButtons release]; Do not release if ARC enabled.
