NS1*_*114 4 javascript html5 objective-c phonegap-plugins cordova
我已经阅读了Cordova的教程,但我不确定他们是否给了我足够的信息.
已编辑以显示更新的代码:
让我告诉你我的代码:
从config.xml:
<plugin name="someMethod" value="MyPluginClass" />
现在为Plugin.h:
#import <Cordova/CDV.h>
@interface MyPluginClass : CDVPlugin
- (void)someMethod:(CDVInvokedUrlCommand*)command;
@end
现在为Plugin.m:
#import "Plugin.h"
@implementation MyPluginClass
- (void)someMethod:(CDVInvokedUrlCommand *)command
{
NSLog(@"YOU ARE READING THIS NATIVELY FROM A PLUGIN");
}
@end
显示的第一个html页面称为"index.html"
我只想要一个空白的html页面,它只运行一个调用cordova.exec()函数的脚本.我这样做的尝试失败了.我不知道我的脚本是否有问题,或者其他地方我做错了但是这里是我的index.html:
<!DOCTYPE html>
<html>
<head>
<title>Cordova Device Ready Example</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.3.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Call onDeviceReady when Cordova is loaded.
//
// At this point, the document has loaded but cordova-2.3.0.js has not.
// When Cordova is loaded and talking with the native device,
// it will call the event `deviceready`.
//
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// Cordova is loaded and it is now safe to make calls Cordova methods
//
function onDeviceReady() {
// Now safe to use the Cordova API
document.addEventListener("deviceready", function() {
cordova.exec(null,null,"MyPluginClass","someMethod",[]);
}, false);
}
</script>
</head>
<body onload="onLoad()">
</body>
</html>
我收到以下错误日志:
2013-01-17 11:36:31.782 CCT [1293:907]错误:找不到插件'MyPluginClass',或者不是CDVPlugin.检查config.xml中的插件映射.
2013-01-17 11:36:31.787 CCT [1293:907] - [CDVCommandQueue executePending] [第103行] FAILED pluginJSON = ["INVALID","MyPluginClass","someMethod",[]]
在设备准备事件触发之前,您无法对cordova进行任何调用.做:
document.addEventListener("deviceready", function() {
cordova.exec(null,null,"MyPluginClass","someMethod",[]);
}, false);
编辑:
对于上面列出的示例调用,您需要一个Objective-C类,如下所示:
@interface MyPluginClass : CDVPlugin
- (void)someMethod:(CDVInvokedUrlCommand*)command;
@end
请注意与调用匹配的类的名称和方法的名称 cordova.exec
另一个编辑:
您config.xml应该看起来像以下内容:
<plugin name="MyPluginClass" value="MyPluginClass" />
(这些不一定必须相同,但name应与javascript调用的第三个参数中的引用匹配,并且value应该与Objective-C类的名称匹配.
