• View > Mode

Code

// objective-c 
self.webView.scalesPageToFit = YES;
self.webView.contentMode = UIViewContentModeScaleAspectFit;

等

その他

[metaタグを挿入する]

var metalist = document.getElementsByTagName('meta');
var hasMeta = false;
for(var i = 0; i < metalist.length; i++) {
    var name = metalist[i].getAttribute('name');
    if(name && name.toLowerCase() === 'viewport') {
        metalist[i].setAttribute('content', 'width=device-width');
        hasMeta = true;
        break;
    }
}
if(!hasMeta) {
    var meta = document.createElement('meta');
    meta.setAttribute('name', 'viewport');
    meta.setAttribute('content', 'width=device-width');
    document.getElementsByTagName('head')[0].appendChild(meta);
}

[webView stringByEvaluatingJavaScriptFromString:JAVASCRIPT_SCRIPT];
