iphone开发必知点之－－push远程通知代码设置，获得DeviceToken

前提是调试或发布时，证书已经启动了push服务

1.注册远程通知类型

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

2.实现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);
    
   //这里可以把deviceToken发给自己的服务器
}

获取失败回调

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

 接收到远程通知

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