我有一些从我的本机代码生成的值,我想传递给phonegap.这些数据是实时生成的,并不直接受用户通过phonegap gui操作的影响.我的本机代码是我制作的插件的一部分.
解决这个问题的最佳方法是什么？我希望有一个函数可以随时发送数据,并在cordova端有一个监听器.我正在使用Cordova 1.5和Xcode 4.3.
这是我到目前为止：
swipe.js：
var swipe={
callNativeFunction: function (success,fail,resultType) {
return Cordova.exec( success,"ca.swipe","nativeFunction",[resultType]); }
};
index.html的：
...
function callNativePlugin( returnSuccess ) {
swipe.callNativeFunction( nativePluginResultHandler,nativePluginErrorHandler,returnSuccess );
}
function nativePluginResultHandler (result) {
alert("SUCCESS: \r\n"+result );
}
function nativePluginErrorHandler (error) {
alert("ERROR: \r\n"+error );
} ... <body onload="onBodyLoad()"> <h1>Hey,it's Cordova!</h1>
<button onclick="callNativePlugin('success');">Success</button>
<button onclick="callNativePlugin('error');">Fail</button>
</body> ...
swipe.h：
... @interface swipe : CDVPlugin - (void) nativeFunction:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options; @end
swipe.m：
...
- (void) nativeFunction:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options {
NSLog(@"Hello,this is a native function called from PhoneGap/Cordova!");
//get the callback id
NSString *callbackId = [arguments pop];
NSString *resultType = [arguments objectAtIndex:0];
NSMutableArray *GlobalArg=arguments;
CDVPluginResult *result;
if ( [resultType isEqualToString:@"success"] ) {
result = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString: @"Success :)"];
//writes back the smiley face to phone gap.
[self writeJavascript:[result toSuccessCallbackString:callbackId]];
}
...
