iOS原生和UniApp通信

1) 原生(OC)向 UniApp发送消息：

iOS项目中代码:

 [self.uniMPInstance sendUniMPEvent:@"NativeEvent" data:@{@"msg":@"native message"}];

UniApp项目中代码:

 uni.onNativeEventReceive((event,data)=>{
				console.log('接收到宿主App消息：' + event + data);
				this.nativeMsg = '接收到宿主App消息 event：' + event + " data: " + data;
			})

2) UniApp 向原生发送消息(打开原始页面)：

UniApp代码:

uni.sendNativeEvent('unimp-event', {
					msg: 'unimp message!!!'
				}, ret => {
					this.nativeMsg = '宿主App回传的数据：' + ret;
				})

iOS代码:

/// 小程序向原生发送事件回调方法
/// @param appid 对应小程序的appid
/// @param event 事件名称
/// @param data 数据：NSString 或 NSDictionary 类型
/// @param callback 回调数据给小程序
- (void)onUniMPEventReceive:(NSString *)appid event:(NSString *)event data:(id)data callback:(DCUniMPKeepAliveCallback)callback {
    NSLog(@"Receive UniMP:%@ event:%@ data:%@",appid,event,data);
    // 根据event字段跳转不同页面
 /// 小程序打开状态，调用此方法可获取小程序对应的 DCUniMPViewController 实例
    UIViewController *uniMPVC = [DCUniMPSDKEngine getUniMPViewController];
    OriginViewController *vc = [[OriginViewController alloc] init];

//    vc.modalPresentationStyle = UIModalPresentationFullScreen;
//
//    [uniMPVC presentViewController:vc animated:YES completion:nil];
    // 前提是打开Uniapp的方式为push，即 configuration.openMode = DCUniMPOpenModePush;
    [uniMPVC.navigationController pushViewController:vc animated:YES];

     // 回传数据给小程序
    // DCUniMPKeepAliveCallback 用法请查看定义说明
    if (callback) {
        callback(@"native callback message",NO);
    }
    }

3) 原生 打开UniApp页面：

UniApp代码:

// 获取配置信息
    DCUniMPConfiguration *configuration = [[DCUniMPConfiguration alloc] init];
    
    // 配置启动小程序时传递的数据（目标小程序可在 App.onLaunch，App.onShow 中获取到启动时传递的数据）
    configuration.extraData = @{ @"launchInfo":@"Hello UniMP" };
    
    // 配置小程序启动后直接打开的页面路径 例：@"pages/component/view/view?action=redirect&password=123456"
    configuration.path = @"pages/component/view/view?action=redirect&password=123456";
    
    // 开启后台运行
    configuration.enableBackground = YES;
    
    // 设置打开方式
    configuration.openMode = DCUniMPOpenModePush;
    
    // 启用侧滑手势关闭小程序
    configuration.enableGestureClose = YES;
    
    __weak __typeof(self)weakSelf = self;
    // 打开小程序
    [DCUniMPSDKEngine openUniMP:k_AppId1 configuration:configuration completed:^(DCUniMPInstance * _Nullable uniMPInstance, NSError * _Nullable error) {
        if (uniMPInstance) {
            weakSelf.uniMPInstance = uniMPInstance;
        } else {
            NSLog(@"打开小程序出错：%@",error);
        }
    }];
