Objective c 弹出窗口可以'；t关闭（iAction不工作）

我使用我在这里找到的弹出式系统：

按照指南一步一步地操作之后，除了关闭按钮外，其他一切都正常工作。我试着用各种方式把它联系起来，但都没用

有人知道我做错了什么吗

这是我的密码：

PopUpController.h：

#import <UIKit/UIKit.h>
//#import <QuartzCore/QuartzCore.h>
#import "AppDelegate.h"


@interface PopUpViewController : UIViewController


@property (weak, nonatomic) IBOutlet UIView *popUpView;

- (void)showInView:(UIView *)aView animated:(BOOL)animated;
- (IBAction)closePopup:(id)sender;


@end

注意：我甚至没有关闭NSLog。。。在我的控制台上单击关闭按钮时

以下是我的.xib文件的屏幕截图：

感谢您的回复。

您是否正确连接（现在将popUpView插座连接到.xib文件中的视图）。从您的引用中，我只是尝试重新链接视图并链接到主视图，但没有任何更改。。（只有按钮不起作用。弹出提示很好）使子视图操作正常。。。您必须添加为子视图控制器。所以要使关闭弹出功能。。。您需要将PopViewController作为子视图控制器添加到要显示弹出窗口的viewController。谢谢@NisarAhmad！就是这样，我添加了这一行：[self-addChildViewController:subV]；它起作用了。我很乐意帮助你

#import "PopUpViewController.h"

@interface PopUpViewController ()
