ios - 添加导致错误的 UIBarButtonItem 数组

Question

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI isSystemItem]: unrecognized selector sent to instance 0x7fa5bbd726f0'

我关注了他的solution here ，显然我没有做错。我正在做的是 - 在导航栏的右侧添加两个按钮(栏按钮)。

     UIBarButtonItem *notificationButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"Notification.png"]
                                                                                  style:UIBarButtonItemStylePlain target:self action:@selector(notificationAction)];
        UIBarButtonItem *searchButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"search"]
                                                                                  style:UIBarButtonItemStylePlain target:self action:@selector(searchAction)];
        NSArray *arrNavigationButtons = [NSArray arrayWithObjects:notificationButtonItem,searchButtonItem, nil];
// warning here - Incompatible pointer type.
        self.navigationItem.rightBarButtonItem = arrNavigationButtons;

Answer 1

将最后一行更改为 rightBarButtonItems。注意末尾的 s。
