<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p><strong>UIRemoteNotification</strong> 是你的 friend 。</p>
<p>1) 为您的应用注册远程推送通知:</p>
<pre><code>[ registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeSound];
</code></pre>
<p>2) 在 applicationDidFinishLaunching 上实现逻辑(处理应用关闭时到达的推送通知)</p>
<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//...
if() {
//if we're here, apps was launched due to Remote Notification
}
//...
}
</code></pre>
<p>3) 在 didReceiveRemoteNotification 上实现登录(处理应用在前台运行时到达的推送通知)</p>
<pre><code>- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
//...
//business logic for GPS Position
//...
}
</code></pre>
<p>在第 2 步和第 3 步中，实现您的业务逻辑以获取实际的 GPS 位置。</p>
