楼主您好，我把这个扫描的demo集成到IOS原声交互的一个方法里，结果它的回调函数一个都不触发

[chentianci123]

代码： #import "DiscoverBeacon.h" #import <React/RCTBridge.h> #import "LocalPush.h"

#import <CoreLocation/CoreLocation.h> #import <CoreBluetooth/CoreBluetooth.h>

#define Beacon_Device_UUID @"FDA50693-A4E2-4FB1-AFCF-C6EB07647825"

@interface DiscoverBeacon () < CLLocationManagerDelegate

/** 检查定位权限 / @property (nonatomic, strong) CLLocationManager locationManager; / 需要被监听的beacon */ @property (nonatomic, strong) CLBeaconRegion *beaconRegion; @property (nonatomic, strong) NSMutableDictionary *dataDict; @end

@implementation DiscoverBeacon

RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(discoverBeacon) { // 在开始监控之前，我们需要判断改设备是否支持，和区域权限请求 BOOL availableMonitor = [CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]];

if (availableMonitor) {
    CLAuthorizationStatus authorizationStatus = [CLLocationManager authorizationStatus];
    switch (authorizationStatus) {
        case kCLAuthorizationStatusNotDetermined:
            [self.locationManager requestAlwaysAuthorization];
            break;
        case kCLAuthorizationStatusRestricted:
        case kCLAuthorizationStatusDenied:
            NSLog(@"受限制或者拒绝");
            break;
        case kCLAuthorizationStatusAuthorizedAlways:
        case kCLAuthorizationStatusAuthorizedWhenInUse:{
            NSLog(@"开启扫描");
            [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
            [self.locationManager startMonitoringForRegion:self.beaconRegion];
        }
            break;
    }
} else {
    NSLog(@"该设备不支持 CLBeaconRegion 区域检测");
}

}

@end

只会打印一个“开启扫描”，开启扫描成功或失败的回调函数都没有触发

[chentianci123]

初始化locationManager和beaconRegion调用了，其他的都没调用
