任何人都可以帮助我们解决“Beacon在IOS10崩溃”的问题。 didRangeBeacons委托方法总是将beacons数组返回为nil，代码如下
-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
@try {
CLBeacon *beacon = [[CLBeacon alloc] init];
NSLog(@"beacons Count %lu", (unsigned long)beacons.count);
if(beacons != nil && beacons != Nil && beacons != NULL && beacons.count > 0) {
beacon = [beacons firstObject];
self.currentMajor = beacon.major;
self.currentMinor = beacon.minor;
NSArray *majorMinorIDs = [[NSArray alloc]initWithObjects:self.currentMajor,self.currentMinor, nil];
self.ComaSeparatedIDS = [majorMinorIDs componentsJoinedByString:@","];
/* Log */
[self printLog:[NSString stringWithFormat:@"Current Major Id: %@, Previous Major Id: %@, Current Minor Id: %@, Previous Minor Id %@", self.currentMajor, self.prevMajor, self.currentMinor, self.prevMinor]];

在设备中启用蓝牙，我已尝试通过更改以下链接中指定的部署目标 Ranging Beacons in iOS 10。并检查数组nil条件，整个代码由目标c中的try catch包围，但即使应用程序因为“Beacon数组为零”而崩溃。 IOS10是否支持Beacon？提前感谢您的帮助。
答案 0 :(得分：1)
有许多关于iOS 10上信标检测问题的轶事报道，有些用户报告将XCode中的应用部署目标设置为9.x将解决此问题。请参阅此处了解详情：
