永久性无法识别的选择器错误[Storyboards] [英] Persistent unrecognized selector error [Storyboards]

问题描述

我已经用按钮和功能设置了一百万个视图.但是由于某种原因，我无法使它正常工作-我已经将它重新制作了3次...我不知道为什么它不起作用...

I have set up a million and one views with button's and functions. But for some reason I can't get this one to work - I've re-made it 3 times now ... I have no idea why it's not working...

从我得到的错误中我了解到，这与情节提要有关(此问题 ...)，因为它在错误中显示: [UIViewController click_newsletter:] 而不是 [LinkedinActionViewController click_newsletter:] .

From the error that I'm getting I understand it has something to do with the storyboard (this question, this question...) because in the error it says: [UIViewController click_newsletter:] not [LinkedinActionViewController click_newsletter:].

问题是，我删除了旧的viewController并做了一个新的，什么都没改变?

The problem is, I deleted the old viewController and made a new one and nothing changed?

在故事板上-类名是相同的.

In the story board - the class name is the same.

@interface LinkedinActionViewController : UINavigationController <UIWebViewDelegate>{
    UIButton *our_page;
    UIButton *newsletter;
}

@property (nonatomic, retain) IBOutlet UIButton *our_page;
@property (nonatomic, retain) IBOutlet UIButton *newsletter;

- (IBAction)click_our_page:(id)sender;
- (IBAction)click_newsletter:(id)sender;


@end

打开视图

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPad" bundle:nil];
        LinkedinActionViewController *action_view = (LinkedinActionViewController*)[[storyboard instantiateViewControllerWithIdentifier:@"LinkedinActionViewController"] retain];
        [self.navigationController pushViewController:action_view animated:YES];

ERRROR !!!

***由于未捕获的异常'NSInvalidArgumentException'而终止应用程序，原因:'-[UIViewControllerclick_newsletter:]:无法识别的选择器已发送到实例0x6d205a0'

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController click_newsletter:]: unrecognized selector sent to instance 0x6d205a0'

为此，我已经在墙上砸了头-任何帮助都将是有益的！:D谢谢！

I've hit my head on the wall with this for over a day - any help would be beneficial! :D THANKS!

如果您转到 linkedinActionViewController.m 文件.

单击右侧窗格中的文件检查器按钮.
