使用swift开发Cordova插件

最近研究了用swift开发cordova插件的问题，事实证明用swift开发cordova插件是完全可行的，不要再去折腾烦人的oc代码了！主要参考了一个地理围栏插件 https://github.com/cowbell/cordova-plugin-geofence ，然后自己根据需求开发了百度地图标注和带扫描效果的二维码扫描iOS cordova插件，官方的那个实在太差了。

用swift开发插件主要是在项目的 Bridging-Header.h中加入Cordova和插件本身用到的头文件，然后插件类定义要以

@objc(HWPXXXXPlugin) class 开头，其它和oc插件基本一样了。示意代码如下`

import Foundation  
import WebKit  

@available(iOS 8.0,*)  
@objc(HWPBaiduMapMarkPlugin) class BaiduMapMarkPlugin : CDVPlugin {  

    func initialize(command: CDVInvokedUrlCommand) {  
        print("BaiduMapMarkPlugin initialization")  
    }  

    func location(command: CDVInvokedUrlCommand) {  
        print("location")  
        var pointUser = PointUser()  
        if command.arguments != nil && command.arguments.count > 0 {  
            let geoInfo = command.arguments[0] as! String  
            print(geoInfo)  
            let point = convertStringToDictionary(geoInfo)  
            print(convertStringToDictionary(geoInfo))  

            pointUser.storeName = point!["storeName"]!  
            pointUser.pro = point!["pro"]!  
            pointUser.city = point!["city"]!  
            pointUser.dist = point!["dist"]!  
            pointUser.address = point!["address"]!  
            pointUser.latitude = Double(point!["latitude"]!)  
            pointUser.longitude = Double(point!["longitude"]!)  
            print(pointUser)  
        }  

        let mapVc = BaiduMapViewController()  
        mapVc.isAnon = true  
        mapVc.pointUser = pointUser  
        mapVc.callBackId = command.callbackId  
        mapVc.baiduMapMarkPlugin = self  
        self.viewController?.presentViewController(mapVc,animated: true,completion: nil)  
    }  

    func convertStringToDictionary(text: String) -> [String:String]? {  
        if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {  
            do {  
                return try NSJSONSerialization.JSONObjectWithData(data,options: []) as? [String:String]  
            } catch let error as NSError {  
                print(error)  
            }  
        }  
        return nil  
    }  
}  `
