13.监控摄像机状态

条件：摄像机连接成功

语法：

1)函数

-(int)monitorStatus:(NSArray*)array; 主动去请求获取参数，不主动请求的话，只有参数有变化才有消息通知

2）消息

FOUNDATION_EXPORT NSString* const IPCamera_Monitor_Status_Notification;
FOUNDATION_EXPORT NSString* const IPCamera_Monitor_Status_Result_Notification;

3) 设置成功后的消息回调

-(void)IPCamera_response_function:(NSNotification*)note;

IPCamera.h宏定义了两种注册消息的方法

#define ADD_IPCAMERA_RESPONSE_WITHOUT_ARG(notice_name) \
    [[NSNotificationCenter defaultCenter] addObserver: self selector:               @selector(IPCamera_response_function:) name: notice_name object: nil]

#define ADD_IPCAMERA_RESPONSE_WITH_ARG(notice_name,camera_object) \
    [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(IPCamera_response_function:) name: notice_name object: camera_object]

示列：

1）注册消息通知

    ADD_IPCAMERA_RESPONSE_WITH_ARG( IPCamera_Monitor_Status_Notification, cam_)
    ADD_IPCAMERA_RESPONSE_WITH_ARG( IPCamera_Monitor_Status_Result_Notification, cam_)

2)请求参数

  NSArray* array = [[ NSArray alloc] initWithObjects:@"alarm",@"humidity", nil ];
[cam_ monitorStatus:m_arry];

3）参数获取成功后的消息回调

-(void)IPCamera_response_function:(NSNotification*)note
{       
   if([note.name isEqualToString: IPCamera_Camera_Statistic_Notification ]){

       if( [note.name isEqualToString: IPCamera_Monitor_Status_Result_Notification ])
       {
        //只有请求成功了，后面摄像机参数有变动，才能监控到，才能每次在PCamera_Monitor_Status_Notification有通知
            NSLog(@"请求监控摄像机状态参数成功！");
        }
       if( [note.name isEqualToString:IPCamera_Monitor_Status_Notification ]){
         NSLog(@"摄像机参数有改变！");  
        NSDictionary* dic = note.userInfo;
        if ([dic objectForKey:@"alarm"]) {
            NSLog(@"报警参数值有改变");
        }     
    }
}
