在我的Xcode中，我有以下内容：

  $(document).ready(function(){
  $(".flip").click(function(){
  $(".panel").slideToggle("slow");
     });
       });

 UIWebView * webView = [[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
 [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"new" ofType:@"html"]isDirectory:NO]]];

 [self.view addSubview:webView];

            {

             div.panel
             {
                 height:120px;

此方法：

  $(document).ready(function(){
  $(".flip").click(function(){
  $(".panel").slideToggle("slow");
     });
       });

 UIWebView * webView = [[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
 [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"new" ofType:@"html"]isDirectory:NO]]];

在我的html文件中：

  $(document).ready(function(){
  $(".flip").click(function(){
  $(".panel").slideToggle("slow");
     });
       });

 UIWebView * webView = [[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
 [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"new" ofType:@"html"]isDirectory:NO]]];

 [self.view addSubview:webView];

这段代码应该处理UIWebView，但它不适用于我我认为我的jQuery函数没有完成或者类似的事情
有什么想法吗？

您可能想尝试另一种方法：包括本地副本或从cdn下载jquery。这两种做法似乎都没有必要

此外：只需在doc2.js中定义一个javascript函数，将该文件包含在HTML中，并直接在Cocoa中调用它。确保将函数公开给Cocoa
