Question

推送通知在应用运行时或在后台运行时调用didReceiveRemoteNotification。但是如果用户杀死了＃34;应用和我发送推送通知，当用户点按通知时，应用不会拨打didReceiveRemoteNotification。

这就是我所拥有的：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)dict{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:dict[@"title"]
                                                message:dict[@"description"]
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];

[alert show];

NSLog(@"didReceiveRemoteNotification: %@", dict);}

根据UIApplicationDelegate协议参考：

如果远程通知到达时应用程序未运行，则方法启动应用程序并提供相应的信息启动选项字典。该应用程序不会调用此方法处理该远程通知。相反，你的实施 application：willFinishLaunchingWithOptions：或 application：didFinishLaunchingWithOptions：方法需要得到远程通知有效载荷数据并做出适当的响应。

当您的应用启动applicationDidFinishLaunching将包含在应用程序终止时收到的任何远程通知的数据。当您的应用程序完成启动时，请使用以下代码。

if ([launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey]) 
{
   [self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
}
