如何在JavaScriptCore中包含外部库?
问题描述：
我正在尝试通过JavaScriptCore加载外部库
I am trying to load a external library via JavaScriptCore
具体来说，我想要这样的最终结果:
Specifically I want the end result of this:
<script src="fancyLibrary.js" type="text/javascript"></script>
但是使用以下语法:
JSContext *context = [[JSContext alloc] initWithVirtualMachine:[[JSVirtualMachine alloc] init]];
[context loadExternalJavascriptFileWithName:@"fancyLibrary.js"];
JSValue *fancyFunction = context[@"fancy"];
目前有可能吗?我认为我可以在应用程序捆绑包中包含外部库，然后从那里调用它.只需将库加载到上下文中即可.
Is this possible at the current time? I figure I can include the external library in the app bundle and call it from there. It's a matter of loading the library into the context.
答
您只需要使用评估API即可在上下文中加载脚本的内容.实际上，这与浏览器遇到脚本标签时的操作非常接近.
You just need to use the evaluation API to load the contents of the script in the context. This is actually pretty close to what a browser does when it encounters a script tag.
NSURL *scriptURL = [NSURL URLWithString:@"path/to/fancyLibrary.js"];
NSError *error = nil;
NSString *script = [NSString stringWithContentsOfURL:scriptURL encoding:NSUTF8StringEncoding error:&error];
[context evaluateScript:script];
