本文介绍了Phonegap Cordova从Objective-C调用javascript函数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 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 AppDelegate.m 。 从插件类可以这样做: NSString * jsString = [NSString stringWithFormat:@myJSFunction(\%@ \);,stringParameter]; [self.webView stringByEvaluatingJavaScriptFromString:jsString]; 插件开发指南 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];Plugin development guide 这篇关于Phonegap Cordova从Objective-C调用javascript函数的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
