将大于iphone视图的图像添加到UIScrollView

Question

如何将大于iphone视图大小的图像添加到UIScrollView？

我尝试将图像添加到UIImageView，仍未连接到UIScrollView，图像缩小以适应UIImageView。

这个结构是如何设置的？

您可能想要做类似的事情：

- (void) resizeScrollContentView
{
    CGSize  viewSize = _imageView.frame.size;
    CGSize  scrollSize = _scroll.frame.size;
    CGPoint p;

    p.x = 0;
    p.y = 0;

    if(viewSize.width < 320)
    {
        p.x = 160 - (viewSize.width / 2.0);
    }

    if(viewSize.height < 460)
    {
        p.y = 200 - (viewSize.height / 2.0);
    }

    _imageView.frame = CGRectMake(p.x, p.y, _imageView.frame.size.width, _imageView.frame.size.height);

    CGSize endScrollSize;
    endScrollSize = _imageView.frame.size;

    _scroll.contentSize = endScrollSize;
}
- (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale
{
    [self resizeScrollContentView];
}

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
    return _imageView;
}
