iOS UIWebView禁用电话号码识别

app中加载H5页面，因Safari的问题会导致部分数字被解读为电话号码，点击可以呼叫，如下方法可禁用

- (void)webViewDidFinishLoad:(UIWebView *)webView{
    NSString *jsMeta = [NSString stringWithFormat:@"var meta = document.createElement('meta');meta.content='telephone=no';meta.name='format-detection';document.getElementsByTagName('head')[0].appendChild(meta);"];
    [webView stringByEvaluatingJavaScriptFromString:jsMeta];
}
