如何判断当前App是否允许使用系统定位功能

如题解答：利用CLLocationManager的一个类方法

[Objective-C] 纯文本查看 复制代码

+ (CLAuthorizationStatus)authorizationStatus
// CLAuthorizationStatus是一个枚举值：
typedef enum {
    kCLAuthorizationStatusNotDetermined = 0, // User has not yet made a choice with regards to this application
    kCLAuthorizationStatusRestricted,        // This application is not authorized to use location services.  Due
                                             // to active restrictions on location services, the user cannot change
                                             // this status, and may not have personally denied authorization
    kCLAuthorizationStatusDenied,            // User has explicitly denied authorization for this application, or
                                             // location services are disabled in Settings
    kCLAuthorizationStatusAuthorized         // User has authorized this application to use location services
} CLAuthorizationStatus;

所以，一切变得简单了

    // 判断本地定位服务开启
    if([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied){
        // 提示用户开启定位服务，PS：iOS8系统会自动检测额
        [SAAlertView showMessage:@"请在系统设置中打开“定位服务”来允许“XXX”确定您的位置"];
    }
