如何向添加到UINavigationControl的{{1}}添加按钮？（该项目不是基于ViewController。）

以下是我添加到UINavigationControler方法的代码：

viewDidLoad

有人可以帮我解决第7-9行吗？

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

您需要UINavigationController吗？为什么不使用简单的UINavigationBar。以下是一些示例代码：

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];
