iphone開發必知點之－－push遠程通知代碼設置，獲得DeviceToken

前提是調試或發布時，證書已經啟動了push服務

1.注冊遠程通知類型

UIRemoteNotificationType apn_type = (UIRemoteNotificationType)(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge);
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:apn_type]; 

2.實現appDelegate的委托方法

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    self.deviceToken = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    
    NSLog(@"deviceToken:%@", self.deviceToken);
    
   //這里可以把deviceToken發給自己的服務器
}

獲取失敗回調

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
     NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@", [error localizedDescription]);
}

 接收到遠程通知

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"receive remote notification:%@", userInfo);
}
