因此，我尝试调用与从xib文件示例化的子视图的FileOwner关联的IBAction
我遇到了一个奇怪的问题，基本上我有一个所有视图都继承的基类：
ViewController.h

#import <UIKit/UIKit.h>
#import "CsoundManager.h"

@interface ViewController : UIViewController
-(IBAction) testActionBase:(id)sender;

@end

ViewController.m

#import "ViewController.h"

@implementation ViewController

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

-(IBAction) testActionBase:(id)sender
{
    NSLog(@"Test Action Fired");
}

@end

然后我还有另外两个视图类，它们继承了这个。一个是示例化子视图的主视图。
主视图文件：MainViewController.h

#import "ViewController.h"

@interface MainViewController : ViewController
-(IBAction) testFireDerived:(id)sender;
@end

MainViewController.m

#import "MainViewController.h"
#import "GlobalSequencerControlView.h"

@implementation MainViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    
    
    GlobalSequencerControlView *globalControlView = [[GlobalSequencerControlView alloc] initWithNibName:@"GlobalSequencerControls" bundle:nil];
    //self.view.userInteractionEnabled = false;
    [self.view addSubview:globalControlView.view];
     
}

-(IBAction) testFireDerived:(id)sender
{
    NSLog(@"Main View Fire Derived");
}

@end

下面是示例化的子类文件：
GlobalSequencerControlView.h

#import "ViewController.h"

@interface GlobalSequencerControlView : ViewController {
    
}
-(IBAction) testFireDerived:(id)sender;
@end

GlobalSequencerControlView.m

#import "GlobalSequencerControlView.h"

@implementation GlobalSequencerControlView

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

-(IBAction) testFireDerived:(id)sender
{
    NSLog(@"Global Sequencer Fire Derived");
}
@end

当我在从xib加载的子视图中连接一个按钮时，我无法执行GlobalSequencerViewController.m中找到的testFireDerived IBAction。按钮接收触摸事件，因为我能够从继承的类中获取testActionBase方法，以便在链接到按钮时触发。
任何想法/想法，为什么这将是非常感谢。按钮似乎正在接收事件，但由于某种原因，派生的动作没有被触发，即使我以完全相同的方式将按钮连接到动作。
