    JHNonRecordableView *view1 = [[JHNonRecordableView alloc] init];
    view1.tag = 100;
    [self.view addSubview:view1];
    view1.frame = self.view.bounds;
    
    // 截屏，或者录屏时，下面 2 个控件将不可见
    [view1.contentView addSubview:({
        UILabel *label = [[UILabel alloc] init];
        label.frame = CGRectMake(20, 200, 200, 40);
        label.text = @"一个标签，可以点击";
        label.backgroundColor = [UIColor lightGrayColor];
        label.textColor = [UIColor blackColor];
        label.font = [UIFont systemFontOfSize:14];
        label.textAlignment = NSTextAlignmentLeft;
        label.userInteractionEnabled = YES;
        [label addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTap)]];
