Question

我试图通过 Java文在网上通话中的功能参考资料,因此,我的目标——C法典在过时的奥杰-C方法完成后可以重新加入这一功能。我看到如何通过简单类型的文件——说明、编号等——但似乎无法说明如何通过某种职能参考,例如通过某种职能参考。

window.myRootObject.myObjCSelector("some-string", function(data) { 
  console.log(data); 
});

我把谷歌 around起来,但继续走得很短,而且 have在docs(yet)中已经提到这一点。在科恰开展工作,但爱能做同样的事。

Thanks in advance for any help!

Edit: The function argument should be anonymous -- hopefully this clarifies. :)

最后,这个数字是这样。也许会有更好的办法(如果是的话,请chim!)但似乎有以下几条。在我的奥贝吉-C(NSObject-derived)类别中,我提到了。 WebView 我界定了以下便于使用的文字方法:

#import <WebKit/WebKit.h>
#import <JavaScriptCore/JavaScriptCore.h>

- (void) search:(NSString *)prefix withCallback:(WebScriptObject *)callback;

......打算提出两个论点:试图寻找证据,并匿名要求处理结果。执行:

- (void) search:(NSString *)prefix withCallback:(WebScriptObject *)callback
{
  // Functions get passed in as WebScriptObjects, which give you access to the function as a JSObject
  JSObjectRef ref = [callback JSObject];

  // Through WebView, you can get to the JS globalContext
  JSContextRef ctx = [[view mainFrame] globalContext];

  // In my case, I have a JSON string I want to pass back into the page as a JavaScript object
  JSValueRef obj = JSValueMakeFromJSONString(ctx, JSStringCreateWithCFString((__bridge CFStringRef)responseString)); 

  // And here s where I call the callback and pass in the JS object
  JSObjectCallAsFunction(ctx, ref, NULL, 1, &obj, NULL);
}

This actually works asynchronously as well, through Objective-C blocks, but the gist is above. Hope it helps someone else!

或许,如果它具有全球非匿名功能,你可以尝试将功能名称传至奥杰-C,然后评价像<条码>。
