在特定场景下我们需要判断用户是否允许应用获取定位权限
1.导入类库：
#import <CoreLocation/CLLocationManager.h>
2.判断用户手机是否开启了定位服务：
这里就要查看CLLocationManager的授权状态，此方法会返回当前授权状态：
[CLLocationManager authorizationStatus]
授权状态为枚举值：
kCLAuthorizationStatusNotDetermined //用户尚未对该应用程序作出选择
kCLAuthorizationStatusRestricted //应用程序的定位权限被限制
kCLAuthorizationStatusAuthorizedAlways //一直允许获取定位
kCLAuthorizationStatusAuthorizedWhenInUse //在使用时允许获取定位
kCLAuthorizationStatusAuthorized //已废弃，相当于一直允许获取定位
kCLAuthorizationStatusDenied //拒绝获取定位
3.判断用户是否授权应用获取定位权限的完整代码:
if ([CLLocationManager locationServicesEnabled] && ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedWhenInUse || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorized)) {
//定位功能可用
}else if ([CLLocationManager authorizationStatus] ==kCLAuthorizationStatusDenied) {
//定位不能用
}
有不足之处还望补充。

//如果没给权限：显示提醒
if ([CLLocationManager locationServicesEnabled] && ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedWhenInUse || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorized)) {
//定位功能可用
shareLocationUploadManager = [DRuploaddataAndLocationManager shareManager];
}else if ([CLLocationManager authorizationStatus] ==kCLAuthorizationStatusDenied) {
//定位不能用
[self showAlertWithTitle:@"请求打开定位权限" Message:@"" CancelTitle:@"不定位" OthersTitles:@[@"定位"] ConfirmHandel:^(NSInteger index) {
if (index==1) {
