如何让UIScrollView始终可滚动

我正在尝试创建一个始终可以垂直滚动的类（ScrollableView：UIScrollView），类似于TableView。我已经硬编码了一个常量值以添加到内容大小，以便它始终可以滚动。但出于某种奇怪的原因，当值为 1 时它不起作用；仅当该值为 4 或更大时才有效。

- (id)initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        self.contentSize = CGSizeMake(frame.size.width, frame.size.height+1);
        self.scrollEnabled = YES;
    }
    return self;
}

还有其他方法可以做到这一点吗？这似乎不是正确的方法。

I'm trying to make a class (ScrollableView : UIScrollView) that can always scroll vertically, similar to a TableView. I've hardcoded a constant value to add to the content size so that it can always be scrollable. For some strange reason though, it won't work when the value is 1; it will only work if the value is 4 or more.

- (id)initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        self.contentSize = CGSizeMake(frame.size.width, frame.size.height+1);
        self.scrollEnabled = YES;
    }
    return self;
}

Is there another way to do this? This doesn't seem to be the proper way.
