startRangingBeaconsSatisfyingConstraint 多个信标

Question

当我对不同区域使用startRangingBeaconsInRegion时didRangeBeacons inRegion可以确定我设置的所有信标，但是当我对startRangingBeaconsSatisfyingConstraint做同样的事情时didRangeBeacons satisfyingConstraint可以确定只有最后一个。是苹果虫吗？

startRangingBeaconsInRegion

for (NSString *uuidString in uuidsString) {
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:uuidString];

    CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithUUID:uuid identifier:uuidString];
    [_locationManager startRangingBeaconsInRegion:region];
}

startRangingBeaconsSatisfyingConstraint

for (NSString *uuidString in uuidsString) {
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:uuidString];        

    CLBeaconIdentityConstraint *beaconIdentityConstraint = [[CLBeaconIdentityConstraint alloc] initWithUUID:uuid];
    [_locationManager startRangingBeaconsSatisfyingConstraint:beaconIdentityConstraint];
}

Answer 1

这似乎是新 startRangingBeaconsSatisfyingConstraint API CoreLocation 中最近引入的错误。

目前的解决方法是使用已弃用的 startRangingBeaconsInRegion API.
