Sliding around does not appear as if the script is required from the html script control
Before webview display, perform the following code, 'main' is the body element, some other parameters according to the actual adjustments.
[Self.mywebView stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat: @ ". Document.getElementById ('main') style.width = '% fpx';", self.mywebView.frame.size.width-12]];

Thank you, I have actually finished, but still very grateful, I tried, only the html of finishload is over in order to obtain the correct size, but the speed will be very slow, so I'll just add a size 30, but finally did not using it. Switch core text of the. Has been completed.
