IPhone development must know-push remote notification code settings to get devicetoken

The premise is that the PUSH Service has been started for the certificate during debugging or publishing.

1. register the remote Notification Type

 
Uiremotenotificationtype apn_type = (uiremotenotificationtype) (uiremotenotificationtypealert | uiremotenotiftypetypesound |Uiremotenotificationtypebadge); [[uiapplication sharedapplication] registerforremotenotificationtypes: apn_type];
 

2. Delegation method for implementing appdelegate

-( Void ) Application :( uiapplication *) Application didregisterforremotenotificationswithdevicetoken :( nsdata * ) Devicetoken {nsstring * Token = [[devicetoken description] stringbytrimmingcharactersinset: [nscharacterset charactersetwithcharactersinstring: @"  <>  " ]; Self. devicetoken = [Token stringbyreplacingoccurrencesofstring: @"   " Withstring: @""  ]; Nslog (  @"  Devicetoken: % @  "  , Self. devicetoken );  //  You can send the devicetoken to your server. }

Callback for failed Retrieval

-(Void) Application :( uiapplication *) Application didfailtoregisterforremotenotificationswitherror :( nserror *) Error {nslog (@"Didfailtoregisterforremotenotificationswitherror: % @", [Error localizeddescription]);}
 

Receive remote notification

 
-(Void) Application :( uiapplication *) Application didreceiveremotenotification :( nsdictionary *) Userinfo {nslog (@"Receive remote notification: % @", Userinfo );}
