加载在线网页后是否可以更改UIWebView的比例？

Question

I would like users to pinch in my UIWebView and already set the ScaleToFitPages to YES.

The page content does not contains anything like

<meta name='viewport' content='width=device-width; initianl-scale=1; maximum-scale:4; ....'>   

Could I use any javascript code(jquery or not with jquery) to change the scale to original scale(1:1) after the page loaded(eg. in the delegate method didFinishLoading ...)

Answer 1

In UIWebViewDelegate , there is protocol webViewDidFinishLoad: that will be call after a web view finishes loading a frame.

so you can put some javascript that custom the scale

[webView stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"your javascript code" ];
