About broadcast monitoring in Android iOS cocos2d

1. About Radio Monitoring

The first use is in Android, broadcast. It is mainly used to transfer data between 2 activity, send out a broadcast, interested in this broadcast to listen to it, to respond accordingly. The main is to pass the data, the trigger mechanism is better, with the global variable or a bit like, but there are differences in the use of occasions, such as the transfer of data between 2 activity, the activity of the life cycle of the global variables and the single case is not appropriate.

2.Android of broadcasting

Send broadcast:

Intent Intent = new Intent ("Our_ble_central_manager_notificaion_change_state");            Intent.putextra ("Key_old_state", oldstate);            Intent.putextra ("Key_new_state", newstate);            Mcontext.sendbroadcast (Intent);

Listen to the broadcast:

private void Registerblebroadcastreceiver ()    {        Intentfilter intentfilter = new Intentfilter ();        Intentfilter.addaction ("Our_ble_central_manager_notificaion_change_state");        This.mContext.registerReceiver (Mblebroadcastreceiver, intentfilter);    }    Private Blebroadcastreceiver mblebroadcastreceiver;    Private class Blebroadcastreceiver extends Broadcastreceiver    {        @Override public        void OnReceive (Context Context, Intent Intent)        {            String action = intent.getaction ();            if (Action.equals ("Our_ble_central_manager_notificaion_change_state"))            {                            }        }    }

Storing and extracting data via intent

3. IOS Notificationcenter

The names in iOS are different and are used almost as follows:

Send notification

Nsdictionary *dictionary = [[Nsdictionary alloc]init];    [[Nsnotificationcenter Defaultcenter] postnotificationname:@ "Our_ble_central_manager_notificaion_change_state"];

Listening:

[[Nsnotificationcenter Defaultcenter] Addobserver:cmios selector: @selector ( Blecentermanagernotificationchangestate:) name:@ "Our_ble_central_manager_notificaion_change_state" Object:nil] ;-(void) Blecentermanagernotificationchangestate: (nsnotification*) value{    log (" Blecentermanagernotificationchangestate ");    Nsdictionary *dictionary = [value object];    NSNumber *oldstate = [dictionary objectforkey:key_old_state];    NSNumber *newstate = [dictionary objectforkey:key_new_state];}

Using dictionaries to pass data

4. Cocos2d a custom event in C + +

The old version of Cocos2d was also named after the notification, and the new one was changed.

Notification occurs:

Customclass retdata;director::getinstance ()->geteventdispatcher ()->dispatchcustomevent ("CbCC_BLE_CENTRAL_ Manager_notificaion_change_state ", &retdata);

Accept data:

_eventdispatcher->addcustomeventlistener ("Cbcc_ble_central_manager_notificaion_change_state", [This] ( Eventcustom* event) {        Customclass *userdata = (Customclass *) Event->getuserdata ();    });

You can pass data through a custom class.

It is convenient to transfer data between different scene,layer, triggering events. Lua's syntax is a little different, essentially the same.
