普元客户端与js交互笔记

Utils 静态工具类

js端

var r = Utils.xxxxx('index.html');//index.html是参数，r是返回值，没有可以不写

oc端

#import "SkyBase.h"
//创建类要继承SkyBase
@interface Skyxxxx : SkyBase
@end

//.m中实现方法--举例
+(SkyDataRef *)getWifiSSID:(NSDictionary *)params{
//    NSString *callNo = [params stringValue:@"phoneNumber"];
    NSString *SSID = @"wifi";
    id info = nil;
    NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
    for (NSString *ifnam in ifs) {
        info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
        info = (NSDictionary *)info;
        if(info[@"SSID"] != NULL)
        {
            SSID = info[@"SSID"];
        }
    }
    return stringToDataRef(SSID);//返回值可以为NULL     return successObjToDataRef(NULL);

}

//oc-js端
util.getWifiSSID = function() {
    return BridgeUtil.invokeStaticMethod("SkyNetwork","getWifiSSID");
}
//或者带有参数
util.tel = function(phoneNumber) {
    BridgeUtil.invokeStaticMethod("SkyModelAppUrl", "tel", {
        "phoneNumber": phoneNumber
    });//SkyModelAppUrl 类名  tel 方法名 后面是json 参数
}

Utils 工具类第二种，需要跳转到oc界面,返回状态

js端

 Utils.CCVideo(json,function(){
       log("登录成功");
     },function(errmsg){
       log(errmsg);
    });

oc端-js代码

//CC 视频接口-直播
var __ccvideo = null;

util.CCVideo =
    function(json,LoginSuccess,LoginFailure){
    if(__ccvideo == null)
        __ccvideo = new Emp.CCtools();
        __ccvideo.showVideo(json,LoginSuccess,LoginFailure);
}
Emp.CCtools =Emp.extend(Emp.Component,{
                        init: function(json) {
                        Emp.CCtools.superclass.init.call(this, json);
                        this.content.xtype = 'SkyCCVideoView';
                        Emp.newNativeObject(this);
                        },
    showVideo:function(json,LoginSuccess,LoginFailure){
                        this.addEvent('CConSuccess',LoginSuccess);
                        this.addEvent('CConFailure',LoginFailure);
                        empBridge.fireModelMethod(this.modelId,"showCCVideo",json);
        
                         }
}

oc-.h 和.m文件

@interface SkyCCVideoView : SkyUiControl

@end

@implementation SkyCCVideoView
-(instancetype)init{
    if (self =[super init]) {
//        self.view = [[UIView alloc] init];
//        [self setUIView:self.view];
    }
    return self;
}
-(void)processAttr{
    [super processAttr];
}
- (UIView *)render {
   return [super render];
}
//-=========集成SkyUiControl的必须三部，//processAttr处理控件所有属性  init创建可能会显示的view   render 渲染布局
//直播
-(SkyDataRef *)showCCVideo:(NSDictionary*)dic{
    /*
    *  必填参数 userId;//用户ID
    *  必填参数 roomId;//房间ID
    *  必填参数 viewerName;//用户名称
    *  必填参数 token;//房间密码--cc后台可设置(此处免密)
     */
    NSString *userId = [dic objectForKey:@"userId"];
    NSString *roomId =[dic objectForKey:@"roomId"];
    NSString *viewerName = [dic objectForKey:@"viewerName"];
    NSString *token;
    if ([[dic allKeys] containsObject:@"token"] && ![[dic objectForKey:@"token"] isEqual:[NSNull null]]) {
       token = [dic objectForKey:@"token"];
    }else{
        token = @"";
    }
    SaveToUserDefaults(WATCH_USERID,userId);
    SaveToUserDefaults(WATCH_ROOMID,roomId);
    SaveToUserDefaults(WATCH_USERNAME,viewerName);
    SaveToUserDefaults(WATCH_PASSWORD,token);
    [self integrationSDK];

//回调的成功事件
    [self triggerEvent:@"CConSuccess",intToDataRef(index),nil];

//跳转界面
[((UIViewController *)self.scriptView.ownerCtrl).navigationController pushViewController:self.playForPCVC animated:YES];
    return NULL;
}
@end

UI 类创建类型

js端代码

//创建需要显示的view
var PDFReaderView = new Emp.PDFReaderView({
    height:"100%",
    width:"100%"
});
contentDiv.add(PDFReaderView);//contentDiv---div的id
//调用方法
PDFReaderView.showPDF(json);
PDFReaderView.getPageCount();

oc--js代码

Emp.PDFReaderView = Emp.extend(Emp.View, {
                               
                    init: function(params) {
                      Emp.PDFView.superclass.init.call(this, params);
                      this.content.xtype = 'SkyPDFReaderView';
                    },
                               
                    // 显示PDF
                    showPDF: function(json) {
                      empPage.fireMethodIfRendered(this, 'showPDF',json);
                    },
                               
                    // 获取pdf总页数
                    getPageCount: function() {
                      return empPage.fireMethodIfRendered(this, 'getPageCount',"");
                    }
}
