我们看到京东商城上的商品详情页是一个大的webview页面，它是可以缩放的。而淘宝的商品详情页面则是一张一张的图片切割组合而成。那么WKWebView的缩放iOS端应该怎么做呢？其实非常简单。
众所周知，UIScrollView是支持手势缩放的，而且用起来非常方便。那么我们只需要把WKWebView放进UIScrollView的容器里即可：
webview_Base = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WDITH, 0)];
webview_Base.backgroundColor = [UIColor clearColor];
webview_Base.maximumZoomScale = 2.0;
webview_Base.minimumZoomScale = 1.0;
webview_Base.zoomScale = 1.0;
webview_Base.delegate = self;
webview_Base.multipleTouchEnabled = YES;
[self.view addSubview:webview_Base];
//上面有webview的创建方法
[webview_Base addSubview:_webView];
创建完成后，只需要实现 UIScrollView的delegate即可：
-(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
if ([scrollView isEqual:webview_Base]) {
return _webView;
}
return nil;
}
-(void)scrollViewDidZoom:(UIScrollView *)scrollView
{
if ([scrollView isEqual:webview_Base]) {
CGFloat offsetX = (scrollView.bounds.size.width > scrollView.contentSize.width)?
(scrollView.bounds.size.width - scrollView.contentSize.width) * 0.5 : 0.0;
CGFloat offsetY = (scrollView.bounds.size.height > scrollView.contentSize.height)?
(scrollView.bounds.size.height - scrollView.contentSize.height) * 0.5 : 0.0;
_webView.center = CGPointMake(scrollView.contentSize.width * 0.5 + offsetX,
scrollView.contentSize.height * 0.5 + offsetY);
}
}
其实这种方法来源于相册的enlarge大图缩放，当然相册在 UIScrollView外面还包了一层 UICollectionView，来处理滑动越界的问题。
