Multiple UIBarButtonItems en UINavigationBar

Question

¿Cómo se puede crear el botón de barra múltiple en la barra de navegación?

Answer 1

Debe utilizar UIToolbar y establecer la barra de herramientas con botones:

// create a toolbar where we can place some buttons 
UIToolbar *toolbar = [[UIToolbar alloc] 
         initWithFrame:CGRectMake(0, 0, 100, 45)]; 
[toolbar setBarStyle: UIBarStyleBlackOpaque]; 

// create an array for the buttons 
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3]; 

// create a standard save button 
UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] 
    initWithBarButtonSystemItem:UIBarButtonSystemItemSave 
    target:self 
    action:@selector(saveAction:)]; 
saveButton.style = UIBarButtonItemStyleBordered; 
[buttons addObject:saveButton]; 

// create a spacer between the buttons 
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] 
    initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace 
    target:nil 
    action:nil]; 
[buttons addObject:spacer]; 

// create a standard delete button with the trash icon 
UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc] 
    initWithBarButtonSystemItem:UIBarButtonSystemItemTrash 
    target:self 
    action:@selector(deleteAction:)]; 
deleteButton.style = UIBarButtonItemStyleBordered; 
[buttons addObject:deleteButton]; 

// put the buttons in the toolbar and release them 
[toolbar setItems:buttons animated:NO]; 

// place the toolbar into the navigation bar 
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] 
              initWithCustomView:toolbar];

you have to create a view with as much button you required and have to add them on navigation button like following : 

    UIView *parentView1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 60, 44)]; 
     UIButton *infoButton1 = [[UIButton alloc] initWithFrame:CGRectMake(0, 6, 30, 32)]; 
     [infoButton1 setBackgroundImage:[UIImage imageNamed: @"navbtn.png"] forState:UIControlStateNormal]; 
     [infoButton1 setTitle:@"Back" forState:UIControlStateNormal]; 
     infoButton1.titleLabel.font = [UIFont systemFontOfSize:13.0f]; 
     infoButton1.titleLabel.textColor = [UIColor whiteColor]; 
     [infoButton1 addTarget:self action:@selector(backBarButtonClicked) forControlEvents:UIControlEventTouchUpInside]; 
     [parentView1 addSubview:infoButton1]; 
     [infoButton1 release]; 

UIButton *infoButton2 = [[UIButton alloc] initWithFrame:CGRectMake(30, 6, 30, 32)]; 
     [infoButton2 setBackgroundImage:[UIImage imageNamed: @"navbtn.png"] forState:UIControlStateNormal]; 
     [infoButton2 setTitle:@"Back" forState:UIControlStateNormal]; 
     infoButton2.titleLabel.font = [UIFont systemFontOfSize:13.0f]; 
     infoButton2.titleLabel.textColor = [UIColor whiteColor]; 
     [infoButton2 addTarget:self action:@selector(backBarButtonClicked) forControlEvents:UIControlEventTouchUpInside]; 
     [parentView1 addSubview:infoButton2]; 
     [infoButton2 release]; 
     UIBarButtonItem *customBarButtomItem1 = [[UIBarButtonItem alloc] initWithCustomView:parentView1]; 
     [parentView1 release]; 
     self.navigationItem.leftBarButtonItem = customBarButtomItem1; 
     [customBarButtomItem1 release];`enter code here` 

Answer 3

Sé que esta pregunta ya estaba cerrado, pero me parece que la solución UIToolbar no coincide visualmente.

Si en su lugar usa un segundo conjunto UINavigationBar con un UINavigationItem que tiene un título de cero y los botones deseados, puede agregar más botones y una barra que coincida visualmente con el original.

Answer 4

Desde iOS 5 en adelante, ahora puede hacerlo utilizando setLeftBarButtonItems:animated: o setRightBarButtonItems:animated:

Answer 5

- (void)viewWillAppear 
{ 

    // get a view and : 
    [self.navigationController.navigationBar addSubView:yourView]; 

} 

Answer 6

Para iOS7 y superior, esta es la forma correcta de hacerlo. No hay necesidad de tonterías UIToolbar.

- (void)viewDidLoad { 

    [super viewDidLoad]; 
    [self configureView]; 

    // create three funky nav bar buttons 
    UIBarButtonItem *one = [[UIBarButtonItem alloc]initWithTitle:@"One" style:UIBarButtonItemStylePlain target:self action:@selector(testMethod)]; 
    UIBarButtonItem *two = [[UIBarButtonItem alloc]initWithTitle:@"Two" style:UIBarButtonItemStylePlain target:self action:@selector(testMethod)]; 
    UIBarButtonItem *three = [[UIBarButtonItem alloc]initWithTitle:@"Three" style:UIBarButtonItemStylePlain target:self action:@selector(testMethod)]; 

    // create a spacer 
    UIBarButtonItem *space = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil]; 
    space.width = 30; 

    NSArray *buttons = @[one, space, two, space, three]; 

    self.navigationItem.rightBarButtonItems = buttons; 
}
