iOS UIBarButtonItem link 到 ViewController

iOS UIBarButtonItem link to ViewController

我对 Storyboard 中的 UIBarButtonItem 到 link 到另一个 ViewController 有疑问。在此顶部栏中,右侧有 2 个图标,使用数组执行此操作:

[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:_meetupButton, _searchButton, nil]];

两个按钮在控制台中都可以使用,但是当我想使用 meetupButton 导航到另一个 ViewController 时,它不起作用。

故事板名称是 Main ViewController 正确地 link 编辑为 MeetupStartViewController

当他运行以下代码时,他崩溃了。我做错了什么?

- (void)toggleMeetup:(UIButton *)button {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"MeetupStartViewController"];
    [self presentViewController:vc animated:YES completion:nil];
}

错误日志:

MeetupStartViewController 是 Swift class 另一个代码是 Objective-C.

您似乎没有为 MeetupStartViewController 设置所需的 ID。

为此,请进入故事板,select MeetupStartViewController。 选中以下复选框:使用 Storyboard ID 并在 StoryboardID 框中写入 "MeetupStartViewController"。这是一个视觉示例:
