react native 开启地理位置受权

在用RN 做获取经纬度的时候，发现地理位置在info中配置了，但是还是没有提醒客户受权，
而后就在原生加了主动受权
原生部分代码：
在 AppDelegate.m中 ：
首选 CLLocationManager *locationManager;
实例话要改成全局的，不然的话会出现 受权弹出框一闪而过的现象
info配置项

<key>NSLocationAlwaysUsageDescription</key>    <string>始终访问地理位置</string>    <key>NSLocationWhenInUseUsageDescription</key>    <string>在使用期间访问地理位置</string>    <key>NSPhotoLibraryUsageDescription</key>

方法：

- (void) getUserLocation {  int status=[CLLocationManager authorizationStatus];  if (![CLLocationManager locationServicesEnabled] || status < 3) {    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8)    {      locationManager = [[CLLocationManager alloc] init];      [locationManager requestAlwaysAuthorization];      [locationManager requestWhenInUseAuthorization];    }  }}

初始化的时候调用

rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];  UIViewController *rootViewController = [UIViewController new];  rootViewController.view = rootView;  self.window.rootViewController = rootViewController;  [self.window makeKeyAndVisible];  [RNSplashScreen show];  //显示启动屏  [self getUserLocation];  return YES;}

主动触发 相关交互类 .m文件代码

#import "openGps.h"#import <CoreLocation/CoreLocation.h>#import <WebKit/WebKit.h>@implementation openGpsCLLocationManager  *locationManager;RCT_EXPORT_MODULE(openGps)RCT_EXPORT_METHOD(openGPS){    BOOL enable=[CLLocationManager locationServicesEnabled];  NSInteger status=[CLLocationManager authorizationStatus];  if(!enable || status<3)  {    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8)    {      locationManager = [[CLLocationManager alloc] init];      [locationManager requestAlwaysAuthorization];      [locationManager requestWhenInUseAuthorization];    }    UIAlertController *alertView=[UIAlertController alertControllerWithTitle:@"APP想要访问您的地理位置以方便订单审核" message:@"定位服务未开启，请进入系统［设置］> [隐私] > [定位服务]中打开开关，并允许使用定位服务" preferredStyle:UIAlertControllerStyleAlert];    UIAlertAction *sureAction=[UIAlertAction actionWithTitle:@"立即开启" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];    }];    UIAlertAction *cancelAction=[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {    }];    [alertView addAction:sureAction];    [alertView addAction:cancelAction];    UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];    UIViewController *mainViewController = keyWindow.rootViewController;    [mainViewController presentViewController:alertView animated:YES completion:nil];  }  }@end

rn 端调用：

   NativeModules.openGps.openGPS()
