富文本 用webview 解析的 有时候图片太大。
添加下边 自适应- (void)webViewDidFinishLoad:(UIWebView *)webView { NSString *js=@"var script = document.createElement('script');" "script.type = 'text/javascript';" "script.text = \"function ResizeImages() { " "var myimg,oldwidth;" "var maxwidth = %f;" "for(i=0;i maxwidth){" "oldwidth = myimg.width;" "myimg.width = %f;" "}" "}" "}\";" "document.getElementsByTagName('head')[0].appendChild(script);"; js=[NSString stringWithFormat:js,[UIScreen mainScreen].bounds.size.width,[UIScreen mainScreen].bounds.size.width-15]; [webView stringByEvaluatingJavaScriptFromString:js]; [webView stringByEvaluatingJavaScriptFromString:@"ResizeImages();"];}
