iOS-UIWebView加载HTMLString图片显示超过屏幕宽度，导致webView可以左右滑动处的理方法

修改webview图片适配的代码，是使用js去修改图片适配屏幕宽度：

// 网络请求加载的数据,进行字典转模型
NSDictionary *dict = [result objectForKey:@"data"];
HQNewsDetailModel *model = [HQNewsDetailModel mj_objectWithKeyValues:dict];

/**
 * model.details就是后台返回的HTMLString
 * " $img[p].style.width = '100%%';
"--->就是设置图片的宽度的
 * 100%代表正好为屏幕的宽度
 */
NSString *htmlString = [NSString stringWithFormat:@"<html> 
"
                   "<head> 
"
                   "<style type="text/css"> 
"
                   "body {font-size:15px;}
"
                   "</style> 
"
                   "</head> 
"
                   "<body>"
                   "<script type='text/javascript'>"
                   "window.onload = function(){
"
                   "var $img = document.getElementsByTagName('img');
"
                   "for(var p in  $img){
"
                   " $img[p].style.width = '100%%';
"
                   "$img[p].style.height ='auto'
"
                   "}
"
                   "}"
                   "</script>%@"
                   "</body>"
                   "</html>",model.details];

// webView直接加载HTMLString
[self.webView loadHTMLString:htmlString baseURL:nil];
