ios - 自定义栏按钮项目不执行 segue

Question

我有一个在 viewDidLoad 中定义的右栏按钮项目:

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    UIButton *helpButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:helpButton ];

}

我已经链接了栏按钮项目并使用标识符执行了segue，但它没有推送 View 。为什么会这样？

- (IBAction)btnShowHelp:(id)sender {

    [self performSegueWithIdentifier:@"showHelp" sender:self];
}

Answer 1

删除按钮和- (IBAction)btnShowHelp:(id)sender 之间的链接，将方法更改为- (void)btnShowHelp(id)sender，然后像这样更改 viewDidLoad 中的代码:

    UIButton *helpButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
    [helpButton addTarget:self action:@selector(btnShowHelp:) forControlEvents:UIControlEventTouchUpInside];

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:helpButton ];
