IOS7下隐私设置中获取各种硬件是否被授权使用

1. 照相机

// TODO: 检查应用是否有使用carema的权限
+ (BOOL)isCameraDeviceAuthorized
{
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    return status == AVAuthorizationStatusAuthorized;
}

2. 定位服务

[CLLocationManager locationServicesEnabled] && [CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorized
