识别推送通知消息
在我的项目中，我想通过推送通知显示事件和优惠，但问题是，我能够显示事件或优惠，而不是两者。 有没有办法识别推送通知的消息。 这是代码：
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { NSString *message = nil; id alert = [userInfo objectForKey:@"alert"]; if ([alert isKindOfClass:[NSString class]]) { message = alert; } else if ([alert isKindOfClass:[NSDictionary class]]) { message = [alert objectForKey:@"body"]; } if (alert) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Title" message:@"AThe message." delegate:self cancelButtonTitle:@"button 1" otherButtonTitles:@"button", nil]; [alertView show]; } NSString *contentsInfo = [userInfo objectForKey:@"contTag"]; NSLog(@"Received contents info : %@", contentsInfo); NSString *nibName = [AppDelegate fetchNibWithViewControllerName:@"EventsViewController"]; EventsViewController *evc = [[EventsViewController alloc] initWithNibName:nibName bundle:nil]; evc.newEvent = YES; [self.navigationController pushViewController:evc animated:YES]; [UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:@"aps"] objectForKey: @"badgecount"] intValue]; } alert始终是一个带有两个键的NSDictionary ：body和show-view。 前者的值是警报消息，后者是Boolean （ false或true ）。 如果为false ，则不显示警报的“查看”按钮。 默认设置是显示“查看”按钮，如果用户点击该按钮，则启动该应用程序。
检查文档
要识别消息的类型，您可以提供其他字段，如此处所述
例：
{ "aps":{ "badge":1, "alert":"This is my special message!", "mycustomvar1":"123456", "mycustomvar2":"some text", "myspecialtext":"This is the best!", "url":"http://www.mywebsite.com" } }
