ios - iOS推送通知发出的位置请求(当应用程序未在后台运行时)

当应用程序不在后台运行时，是否可以发送iOS推送通知以获取位置？就像“查找我的iPhone”一样。

最佳答案

UIRemoteNotification 是您的 friend 。

1)注册您的应用以进行远程推送通知:

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:  UIRemoteNotificationTypeAlert |
                                                                        UIRemoteNotificationTypeBadge |
                                                                        UIRemoteNotificationTypeSound];

2)在applicationDidFinishLaunching上实现逻辑(处理关闭应用程序时到达的推送通知)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //...

    if([launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]) {
        //if we're here, apps was launched due to Remote Notification

    }

    //...
}

3)在didReceiveRemoteNotification上实现登录(以处理当应用程序在前台运行时到达的推送通知)

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    //...
    //business logic for GPS Position
    //...
}

在步骤2和3中，实施您的业务逻辑以获取实际的GPS位置。
