当应用程序不在后台运行时,是否可以发送 iOS 推送通知来获取位置?就像查找我的 iPhone 一样..

UIRemoteNotification 是你的 friend 。
1) 为您的应用注册远程推送通知:
[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeSound];
2) 在 applicationDidFinishLaunching 上实现逻辑(处理应用关闭时到达的推送通知)
- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions
{
//...
if([launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]) {
//if we're here, apps was launched due to Remote Notification
}
//...
}
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)
- (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)userInfo {
//...
//business logic for GPS Position
//...
}
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。
