IPhone之navigationItem

注：

使用其navigationItem时，首先要确保UINavigationController 视图已经加载到ViewController中。

其代码为：

[[UINavigationController alloc] initWithRootViewController:viewController];

1、添加按钮

UIBarButtonItem *loginBut =[[UIBarButtonItem alloc] initWithTitle:@"Login" style:UIBarButtonItemStylePlain target:self action:@selector(login)];
    self.navigationItem.rightBarButtonItem = loginBut;
    [loginBut release];

    UIBarButtonItem *createBut =[[UIBarButtonItem alloc] initWithTitle:@"NEW" style:UIBarButtonItemStylePlain target:self action:@selector(creatUser)];
    self.navigationItem.leftBarButtonItem = createBut;
    [createBut release];

2、添加segmentedControl

UISegmentedControl *m_segmentedControl = [[UISegmentedControl alloc] initWithItems:
                                            [NSArray arrayWithObjects:
                                            [UIImage imageNamed:@"up.png"],
                                            [UIImage imageNamed:@"down.png"],
                                            nil]];
    [m_segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    m_segmentedControl.frame = CGRectMake(0, 0, 90, 30);
    m_segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    m_segmentedControl.momentary = YES;

    UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:m_segmentedControl];
    [m_segmentedControl release];

    self.navigationItem.rightBarButtonItem = segmentBarItem;
    [segmentBarItem release];

3、设置标题

self.navigationItem.title = @"详细内容";

4、设置返回按钮

self.navigationItem.backBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"主菜单" style:UIBarButtonItemStylePlain target:nil action:nil] autorelease];
