TouchesEnded is not notified

We are developing with objective-c.

I am trying to operate a project created about 6 years ago and operated until about 4 years ago with the version of Xcode 12.5 again. There is a place to process by touching the thumbnail image,

・ On iPhone 5 devices with iOS 10.3.4, a notification will be sent to touches Ended.

・ Notification does not come to touchesEnded on iPad (7th generation) of iOS 14.8.1.

・ Notification does not come to touchesEnded on the emulator of iPhone12.

The behavior is different like. Thumbnail image

- (void)setupLayer
{
    imageLayer_ = [[UIImageView alloc]initWithFrame:self.bounds];
    imageLayer_.frame = self.bounds;
    videoLayer_ = [[UIImageView alloc]initWithFrame:self.bounds];
    videoLayer_.frame = self.bounds;
    duration_ = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 40, 15)];
    duration_.backgroundColor = [UIColor clearColor];
    duration_.frame = CGRectMake(30, 60, 40, 15);
    [self addSubview:imageLayer_];
    [self addSubview:videoLayer_];
    [self addSubview:duration_];
}

- (void)setSelected:(BOOL)selected
{
    thumbnail_.selected = selected;
    //self.btImageView.userInteractionEnabled = YES;
    
    if (selected) {
        if (selectedCover_ == nil) {
            selectedCover_ = [[ThumbnailViewCellSelectedCover alloc]initWithFrame:self.bounds];
            selectedCover_.backgroundColor = [UIColor clearColor];
        }
        [self addSubview:selectedCover_];
    } else {
        [selectedCover_ removeFromSuperview];
    }
}
- (id)init
{
    self = [super initWithFrame:CGRectMake(0, 0, 75, 75)];
    if (self) {
        [self setupLayer];
    }
    return self;
}

- (void)dealloc
{
    SAFE_RELEASE(imageLayer_);
    SAFE_RELEASE(videoLayer_);
    SAFE_RELEASE(duration_);
    [thumbnail_ release];
    [selectedCover_ release];
    [super dealloc];
}

- (void)setThumbnail:(Thumbnail *)thumbnail
{
    isSetup = YES;
    SAFE_RELEASE(thumbnail_);
    thumbnail_ = [thumbnail retain];
    NSString *imageName = [PBApplicationDirectoryManager getFullFilePathWithFilePath:thumbnail.photo.thumbnail];
    [self setSelected:thumbnail.selected];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (!isSetup) {
        return;
    }

    NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
    [params setValue:[NSString stringWithFormat:@"%ld", (long)thumbnail_.index] forKey:@"index"];
    [params setValue:[NSString stringWithFormat:@"%@", ((thumbnail_.selected == YES)?@"YES":@"NO")] forKey:@"selected"];
    [params setValue:self forKey:@"thumbnailView"];
    
    NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
    NSNotification *notification = [NSNotification notificationWithName:ThumbnailTouchEvent object:self userInfo:params];
    [center postNotification:notification];
    
    [params release];
}

I am creating it with a code like this. Since it works on the iPhone 5 terminal of iOS 10.3.4, I think that it is not a code problem but a setting due to the difference in OS version is necessary. What should i add

I look forward to working with you.
