1.在文件info.pilist 中導入 NSLocationWhenInUseUsageDescription

//IOS8 新功能用戶開啓定位
2.appDelegate中帶入 #import <CoreLocation/CoreLocation.h>

3.加入下面的語句
CLLocationManager* location = [CLLocationManager new];
[location requestAlwaysAuthorization];

再次運行軟件就能夠定位了。
緣由以下：
scussion:
* When +authorizationStatus == kCLAuthorizationStatusNotDetermined,
* calling this method will trigger a prompt to request "always"
* authorization from the user. If possible, perform this call in response
* to direct user request for a location-based service so that the reason
* for the prompt will be clear. Any authorization change as a result of
* the prompt will be reflected via the usual delegate callback:
* -locationManager:didChangeAuthorizationStatus:.
*
* If received, "always" authorization grants access to the user's
* location via any CLLocationManager API, and grants access to
* launch-capable monitoring API such as geofencing/region monitoring,
* significante location visits, etc. Even if killed by the user, launch
* events triggered by monitored regions or visit patterns will cause a
* relaunch.
*
* "Always" authorization presents a significant risk to user privacy, and
* as such requesting it is discouraged unless background launch behavior
* is genuinely required. Do not call +requestAlwaysAuthorization unless
* you think users will thank you for doing so.
*
* When +authorizationStatus != kCLAuthorizationStatusNotDetermined, (ie
* generally after the first call) this method will do nothing.
*
* If the NSLocationAlwaysUsageDescription key is not specified in your
* Info.plist, this method will do nothing, as your app will be assumed not
* to support Always authorization.

大概意思就是說：IOS8 新增長了一個選項，若是要開啓定位這個隱私選項的話須要在Pilist導入NSLocationWhenInUseUsageDescription，而後掉用 requestAlwaysAuthorization這個方法。此方法執行後，當要執行定位功能的時候就會觸發一個詢問，詢問用戶是否使用定位功能，若是選擇是，則啓動定位功能，若是選擇否，則方法返回，下次還將繼續詢問用戶。
