1.设置字体大小
-(void)webViewDidFinishLoad:(UIWebView *)webView{[webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '40%'"];//修改百分比即可}
2.设置webView内容宽度等于屏幕宽度显示,设置webView的缩放效果
NSString *meta = [NSString stringWithFormat:@"document.getElementsByName(\"viewport\")[0].content = \"width=self.view.frame.size.width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no\""];[webView stringByEvaluatingJavaScriptFromString:meta];//(initial-scale是初始缩放比,minimum-scale=1.0最小缩放比,maximum-scale=5.0最大缩放比,user-scalable=yes是否支持缩放)
或者服务端修改:(未测试)
<html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
