如何在Objective-C的UIWebview中将.js文件加载到HTML中

问题描述：

我正在现有的iOS应用中做一些wave动画.它由Objective-C语言实现.因此，我有.Js和HTML页面.在HTML页面中，我正在加载.js文件，并尝试使用UIWebview加载HTML文件.

I am doing some waves animation in my existing iOS app. Its implemented by Objective-C language. So, I have .Js and HTML pages. In HTML page, I am loading .js file and trying to loading HTML file with UIWebview.

但是，它始终显示空白的白屏，我也搜索了很多论坛，发现只能加载只能找到的HTML页面，找不到将UI文件加载到UIWebview的HTML页面中的

But, Always its showing Blank white screen, I searched so many forums too, I found only loading HTML pages only able to found, I din't found for loading .js file into HTML page for UIWebview.

//以下是我的代码.

@property (nonatomic, weak) IBOutlet UIWebView *animationView;

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *filePathh=[[NSBundle mainBundle]pathForResource:@"voicewave" ofType:@"html" inDirectory:nil];

    NSLog(@"%@",filePathh);
    NSString *htmlstring=[NSString stringWithContentsOfFile:filePathh encoding:NSUTF8StringEncoding error:nil];

 //   [_animationView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePathh]]];
    [_animationView loadHTMLString:htmlstring baseURL:nil];
}

HTML代码是

<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
    <style>
        .container {
        background: rgba(232, 17, 17, 0);
        }
    </style>
<body>
<div id="container-ios9" class="container"></div>
<script src="wave9.js"></script>
<script>
         var $wave_ios9 = document.getElementById('container-ios9');
         var SW9 = new Wave9({
                         height: 40,
                         speed: 0.2,
                         amplitude: 0.1,
                         container: $wave_ios9,
                         autostart: false,
         });
      </script>
</body>
</html>

任何人都可以建议我，如何解决此问题并将其动画代码加载到Webview中.即使我尝试使用WkWebview，也得出了相同的结果.

Can anyone suggest me, how to fix this and load my animation code in Webview. Even I tried with WkWebview, but, same result came.

如果它是唯一没有.js的HTML文件，则会加载它，但是，如果我将.js文件包含到html文件中，则会显示空白屏幕.

If its only Html file without .js, its loading, but, if I inclued .js file into html file, its showing blank white screen.

答

问题是js文件代码无法正确加载HTML文件.这就是问题.我们终于修复了它.

The problem is js file code is not loading properly with HTML file. This is the issue. We have fixed it finally.
