如何将右按钮添加到uinavigationcontrol

Question

如何将按钮添加到我添加到ViewController的UINavigationControl？(该项目不是基于UINavigationControler的。)

下面是我添加到viewDidLoad方法中的代码：

navigation = [[UINavigationController alloc] init];
navigation.view.frame = CGRectMake(0, 0, 1024, 748);
navigation.navigationBar.tintColor = [UIColor blackColor];
navigation.navigationBar.alpha = 1.0f;
navigation.navigationBar.translucent = NO;

UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStylePlain target:self action:@selector(cancel)];          
[navigation.navigationItem setRightBarButtonItem:cancelButton animated:YES];
[cancelButton release];

[self.view addSubview:navigation.view];

[self pushPresentationList];

有人能帮我修一下7-9线吗？

Answer 1

UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Button" 
    style:UIBarButtonSystemItemDone target:nil action:nil];
UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@"Awesome"];
item.rightBarButtonItem = rightButton;
item.hidesBackButton = YES;
[navigationBar pushNavigationItem:item animated:NO];

Answer 2

你需要UINavigationController吗？为什么不使用一个简单的UINavigationBar呢？下面是一些示例代码：

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:
                              CGRectMake(0,0,self.view.frame.size.width, 49.0f)];
[self.view addSubview:navBar];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel"
      style:UIBarButtonItemStylePlain target:self action:@selector(cancel)];
UINavigationItem *rightBarButtonItem = [[UINavigationItem alloc] init];

[rightBarButtonItem setRightBarButtonItem:cancelButton];

[navBar pushNavigationItem:rightBarButtonItem animated:NO];
