objective-c - 如何向 uinavigationcontroller 添加右键

Question

如何向已添加到 ViewController 的 UINavigationControl 添加按钮？ (该项目不是基于 UINavigationControler 的。)

这是我添加到 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];

有人可以帮我修复第 7-9 行吗？

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];
