1、在使用CoreLocation前需要调用如下函数【iOS8专用】:
iOS8对定位进行了一些修改,其中包括定位授权的方法,CLLocationManager增加了下面的两个方法:
(1)始终允许访问位置信息
-
(void)requestAlwaysAuthorization;
(2)使用应用程序期间允许访问位置数据
-
(void)requestWhenInUseAuthorization;
示例如下:
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">1</span>
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">2</span>
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">3</span>
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">4</span>
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">5</span>
<span class="line-number" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; vertical-align: baseline; color: rgb(88, 110, 117) !important;">6</span>

self.locationManager = [[CLLocationManager alloc]init];
_locationManager.delegate = self;
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
_locationManager.distanceFilter = 10;
[_locationManager requestAlwaysAuthorization];//添加这句
[_locationManager startUpdatingLocation];

2、在Info.plist文件中添加如下配置:
(1)NSLocationAlwaysUsageDescription
(2)NSLocationWhenInUseUsageDescription
这两个键的值就是授权alert的描述,示例配置如下[勾选Show
Raw Keys/Values后进行添加
