iPhone dev: Increase scroll speed in UIWebView?

Question

I have an app in which I render local HTML files in a UIWebView. The files, however, are sometimes large, and getting to where you want takes a long time with the default scroll

Old question but these setting or trick really helped me even in 2018.

Follow these simple coding tricks to improve Android WebView Performance:

WebView mWebView = new WebView(this);
WebSettings settings = mWebView.getSettings();
settings.setSupportZoom(true);
settings.setBuiltInZoomControls(false);
settings.setJavaScriptEnabled(true);
settings.setLoadWithOverviewMode(true);
settings.setUseWideViewPort(true);
mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
mWebView.setScrollbarFadingEnabled(true);
settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
settings.setCacheMode(WebSettings.LOAD_NO_CACHE);
settings.setDomStorageEnabled(true);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

    mWebView.setLayerType(View.LAYER_TYPE_HARDWARE, null);

} else {
mWebView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
