Phonegap Cordova从Objective-C调用javascript函数 [英] Phonegap Cordova call javascript functions from Objective-C

问题描述

我在我的PhoneGap应用程序中面临一些Objective-C缺乏的知识。

我有一个库，我需要在Objective-C中实现。这个库有一些回调，我收到一个委托类（称为CCController）：

  [MyLib sharedInstance] .delegate = self; 
  

这个类在AppDelegate.m中是类似的：

  CCController * myClass = [CCController alloc]; 
 [myClass init];然后，当我的Lib发送事件时，我的CCController中的函数被调用。 
我需要，在这一点上，用一个参数调用我的Javascript函数。
 
 
 
我如何实现这个？ 
 
 
 
我试过调用AppDelegate.m中的函数，其中包含：
  NSString * jsString = [NSString stringWithFormat：@myJSFunction（\％@ \）;，stringParameter]; 
 [self.viewController.webView stringByEvaluatingJavaScriptFromString：jsString]; 
  
但是没有成功，我的JS中没有调用... 
 
 
 
如何实现？感谢您的帮助：）
解决方案
您必须创建一个插件并将原生代码放在< $ c> AppDelegate.m 。 
 
 
 
从插件类可以这样做：
  NSString * jsString = [NSString stringWithFormat：@myJSFunction（\％@ \）;，stringParameter]; 
 [self.webView stringByEvaluatingJavaScriptFromString：jsString];

I am facing some Objective-C lackiness of knowledge in my PhoneGap App.

I have a library that I need to implement in Objective-C. This Library has some callbacks that I receive in a delegate Class ( called CCController ) : 
[MyLib sharedInstance].delegate = self;
This Class is instanciated in the AppDelegate.m like this : 
CCController *myClass = [CCController alloc];
[myClass init];
Then, when my Lib sends events, the functions in my CCController are called.
I need, at this point, to call my Javascript functions with a parameter.

How can I implement this ? 

I have tried calling a function in AppDelegate.m which contains this : 
NSString* jsString = [NSString stringWithFormat:@"myJSFunction(\"%@\");", stringParameter];
[self.viewController.webView stringByEvaluatingJavaScriptFromString:jsString];
But without success, nothing is called in my JS...

How can I implement this ? Thanks for help :)
解决方案
You have to create a plugin and put the native code there instead using it in the AppDelegate.m. 

From the plugin class you can do this:
NSString* jsString = [NSString stringWithFormat:@"myJSFunction(\"%@\");", stringParameter];
[self.webView stringByEvaluatingJavaScriptFromString:jsString];
