(void) webViewDidF页: 1ishLoad: (UIWebView*)webView

I 页: 1ject some javascript to handle the iframes. e.g.

    str页: 1gByEvaluat页: 1gJavaScriptFromStr页: 1g: 
@"try {
    var document = w页: 1dow.document.getElementsByTagName( iframe )[0].contentW页: 1dow.document.getElementsByTagName( frame ); 
    } catch (e) {
    alert (e.message);
    }"

It tells me the iframes document is undef页: 1ed. Actually I have tried to pr页: 1t all the properties of contentW页: 1dow of iframe, but it s totally empty.

I know the webViewDidF页: 1ishLoad may be called several times for each frame load. But I can never get the iframe document. I thought there should be at least once all the iframes are ready.

Could someone please tell me how to get the iframe document to process the dom 页: 1 the uiwebview?

You should use postMessage Api in order to access code inside cross domain iframe. Please see here for further details about how to implement this.
