添加导航控制器的 UIButton 顶栏，推送到另一个 viewController
我有一个 UIButton，它使用以下代码推送到另一个视图控制器。我该如何将此 UIButton 放置到导航控制器的顶部栏。
-(IBAction) nextButtonPressed {
TipsViewController *objYourViewController = [[TipsViewController alloc] initWithNibName:@"TipsViewController" bundle:nil];
[self.navigationController pushViewController:objYourViewController animated:YES];
[TipsViewController release];
}
我正在考虑在某处添加类似以下内容的内容： self.navigationItem.rightBarButtonItem ，但无法弄清楚语法。
这是我使用以下代码尝试的其他内容：我可以在导航控制器的顶部栏中找到“下一步”按钮。我如何将其推送到另一个视图控制器？
UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self pushViewController:anotherButton animated:YES];
self.navigationItem.rightBarButtonItem = anotherButton;
[anotherButton release];
感谢您的帮助。
I have a UIButton that pushes to another view controller using the following code. How do I go about putting this UIButton to the top bar of a navigation controller.
-(IBAction) nextButtonPressed {
TipsViewController *objYourViewController = [[TipsViewController alloc] initWithNibName:@"TipsViewController" bundle:nil];
[self.navigationController pushViewController:objYourViewController animated:YES];
[TipsViewController release];
}
I was thinking of adding something like: self.navigationItem.rightBarButtonItem somewhere, but can't figure out the syntax.
Here's something else I tried with the following code: I can get a "Next" button in the top bar of the Navigation Controller. How would I get it to push to another view controller?
UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self pushViewController:anotherButton animated:YES];
self.navigationItem.rightBarButtonItem = anotherButton;
[anotherButton release];
thanks for any help.

当您初始化 UIBarButtonItem 时，您是否看到一个名为 action: 的参数？在那里提及一个选择器：
上面的项目应该是您想要的 rightBarButton。
这将是你的选择器：
When you init your UIBarButtonItem, do you see a parameter called action: ? Mention a selector there:
The above item should be your rightBarButton as you want it to be.
And this would be your selector:
UIBarButtonItem addButton=[[UIBarButtonItem alloc]initWithTitle:@"+" style:UIBarButtonItemStyleBordered target:self action:@selector(method)];
UIBarButtonItem addButton=[[UIBarButtonItem alloc]initWithTitle:@"+" style:UIBarButtonItemStyleBordered target:self action:@selector(method)];
