如何在NavigationBar上添加5按钮

Question

如何在UINavigation栏上添加大约5个按钮。

我很好，我们可以向左右添加按钮进行导航

使用UIToolbar，我们在导航栏上添加按钮。

还有其他适合导航栏周围五个按钮的方式。 苹果被接受的地方

Answer 1

您可以始终使用[self.navigationController.navigationBar addSubview: abutton]; 。

Answer 2

NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:5];

// create a standard "1" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:NULL];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];

//for spacer
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];

// create a standard "2" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];

// and so on you can create rest button in the same way and add to tools
// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];
[buttons release];
 // and put the toolbar in the nav bar
 self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]   initWithCustomView:tools];
[tools release];
