NavigationController导航栏中添加多个UIBarButtonItem

在实际的开发中，导航器是最重要的容器之一，我们经常要在导航栏中添加各种样式的按钮，添加一个按钮很简单，代码如下图：

UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Setting" style:UITabBarSystemItemContacts                                                                  target:self action:@selector(clickSettings:)];          self.navigationItem.rightBarButtonItem = anotherButton; [anotherButton release];

其中按钮的样式可以有多种，具体的可以参考：https://developer.apple.com/library/ios/prerelease/#documentation/UIKit/Reference/UIBarButtonItem_Class/

在有些项目中要在右面添加两个按钮，实现的样式如下图：

 

实现的代码如下图：

UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 150, 45)]; [tools setTintColor:[self.navigationController.navigationBar tintColor]]; [tools setAlpha:[self.navigationController.navigationBar alpha]]; NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:2];

UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd                         target:self action:@selector(clickSettings:)];

UIBarButtonItem *anotherButton1 = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UITabBarSystemItemContacts                                                         target:self action:@selector(clickEdit:)]; [buttons addObject:anotherButton]; [anotherButton release]; [buttons addObject:anotherButton1]; [anotherButton1 release]; [tools setItems:buttons animated:NO]; [buttons release]; UIBarButtonItem *myBtn = [[UIBarButtonItem alloc] initWithCustomView:tools]; self.navigationItem.rightBarButtonItem = myBtn;

[myBtn release]; [tools release];
