swift,在后台检测ibeacons,并在范围内发送通知
您好,我是IBeacons的新手,也是swift的初学者,我正在尝试制作一个小应用程序,在应用程序的背景上检测Ibeacon,并在Ibeacon在范围内时发送通知。我成功地做到了这一点,但只有当我在应用程序打开时走路时,我才能让它工作,并在背景上搜索IBeacons,即使我给了应用程序通过使用在后台获取位置的访问权限swift,在后台检测ibeacons,并在范围内发送通知,swift,ibeacon,Swift,Ibeacon,您好,我是IBeacons的新手,也是swift的初学者,我正在尝试制作一个小应用程序,在应用程序的背景上检测Ibeacon,并在Ibeacon在范围内时发送通知。我成功地做到了这一点,但只有当我在应用程序打开时走路时,我才能让它工作,并在背景上搜索IBeacons,即使我给了应用程序通过使用在后台获取位置的访问权限 if (CLLocationManager.authorizationStatus() != CLAuthorizationStatus.authorizedAlways) {
if (CLLocationManager.authorizationStatus() != CLAuthorizationStatus.authorizedAlways) {
locationManager.requestAlwaysAuthorization();
}
这是我的主要问题,我也有一个副问题,即应用程序不保存人名,如果应用程序关闭并再次打开,应用程序将忘记人名。这是我的代码,我非常感谢您的帮助。如果您有任何参考资料来了解更多关于IBeacons应用程序的信息,我将不胜感激

重写func viewDidLoad(){
super.viewDidLoad()
locationManager.delegate=self
UNUserNotificationCenter.current().requestAuthorization(选项:[.alert、.sound、.badge],completionHandler:{didAllow,错误在})
设uuid=uuid(UUIString:“E2C56DB5-DFFB-48D2-B060-D0F5A71096E0”)!
设beaconRegion=CLBeaconRegion(proximityuid:uuid,major:444,minor:333,标识符:“abcdefac005b”)
if(CLLocationManager.authorizationStatus()!=CLAuthorizationStatus.AuthorizationDalWays){
locationManager.requestAlwaysAuthorization();
}
locationManager.startRangingBeacons(位于:信标区域)
}
重写函数didReceiveMemoryWarning(){
超级。我收到了记忆警告()
}
func locationManager(manager:CLLocationManager,didRangeBeacons信标:[CLBeacon],区域内:CLBeaconRegion){
打印(信标)
如果(beacons.count>0){
如果(!sendYet){
如果信标[0].approxity.rawValue<2{
textLbl.text=“在房间里”
sendHiNoti()
sendYet=true;
}
}
如果信标[0].approxity.rawValue>=3,则为else{
textLbl.text=“房间外”
sendByeNoti()
sendYet=false;
}
}
}
}
显示的代码使用信标测距locationManager.startRangingBeacons(在:beaconRegion)
,在前台和后台之间转换后,在后台通常不支持超过10秒
locationManager.requestAlwaysAuthorization()
将仅解锁在后台使用信标监控的功能。信标监控在信标第一次出现(didnenter(region:region)
)或全部消失(didExit(region:region)
)时为您提供一次呼叫。
这是唯一在正常情况下在后台工作的BeaconAPI
可以使用两种技术在后台进行超过10秒的信标测距:
<key>UIBackgroundModes</key>
<array>
<string>location</string>
</array>
非常感谢这对我帮助很大我真的很感激
