ios9定位服務的app進入后臺三分鐘收不到經緯度，應用被掛起問題及解決方案

原來定位服務是10分鐘收不到定位信息就掛起定位，現在變成最短3分鐘，估計都是為了省電吧。只要你開啟利用的后臺定位，并且10分鐘有1次定位，那末蘋果就不會關閉你的線程，現在變成3分鐘。若你的利用開啟了后臺定位，當最短3分鐘（經過測試也可能大于3分鐘小于等于10分鐘）不定位，ios系統也會把你的利用掛起。而高德地圖ios sdk的ios9以上版本后臺定位開啟方法變更，而高德導航庫沒有同步變更，致使使用老的地圖庫和高德導航地圖庫的用戶定位服務不能實際開啟，切換到后臺3分鐘（經過測試也可能大于3分鐘小于等于10分鐘）沒有實際定位要求，被ios系統認為是偽定位服務的利用并掛起線程。而高德定位模塊也有問題，有時間也有不定位的情況。如：手機開啟后臺定位的利用，網絡連接wifi（aibinjian）切換到后臺,當用戶移動到wifi覆蓋區外，那末利用收到網絡異常通知，手機的網絡自動切換到4g手機網絡，利用沒有收到網絡正常通知，致使利用在8分鐘后不定位，并且利用被系統干掉。當手機沒有網絡時高德也不定位，而原生態的定位在有網和無網絡的情況下都能定位，所以還是用原生態的定位更靠譜。
高德地圖iOS SDK V2.5.0版本提供后臺延續定位的能力，即使你的app退到后臺，且位置不變動時，也不會被系統掛起，可持久記錄位置信息。該功能適用于記錄軌跡錄或出行類App司機端。
只需要您的做以下幾步操作：
1.添加代碼。
對iOS9之前的系統：
1
_mapView.pausesLocationUpdatesAutomatically = NO;
對iOS9（含）以上系統：
1
_mapView.allowsBackgroundLocationUpdates = YES;
若你的利用有3D地圖和導航地圖，那末你的利用用的應當是導航地圖，若想用定位由于導航地圖沒有更新，估計你的利用沒有allowsBackgroundLocationUpdates 這個屬性，只能讓你憂愁了。
高德導航地圖庫千呼萬換始終不出來，需要后臺定位服務的利用不可能等待這個大爺吧！只能用替換方案了。開啟原生態的定位服務，只是不用原生態的位置，能夠保證高德地圖1致獲得到經緯度，仍舊用高德的經緯。原生態的位置服務只是觸發高德地圖收到經緯度和保持后臺定位。

現在高德地圖終究發布了新的支持ios9系統后臺定位的導航地圖包，并且發布了高德地圖定位模塊，支持1次定位的功能，能夠1次定位到你的位置信息和cityCode。但是還存在利用在后臺無網絡不定位的可能被系統干掉的情況，建議仍舊ios原生定位的功能吧。
ios9.1以后，為了省電，利用切換到后臺8分鐘，不論是否是開啟了后臺定位服務，只要沒有網絡活動都有可能被掛起。所以你的利用切換到后臺要保證8分鐘以內有1次網絡活動（如心跳等）。若用戶打開利用去打電話，不知道網絡沒有了，等打10多分鐘的電話，再去看利用，結果利用早掛了，這個問題很坑爹，暫時沒有找到緣由。不知道是高德定位弄的鬼還是最新的iphone系統的問題。估計是高德地圖問題多些！
