无法在 iphone 6 上检测到 ibeacon
Unable to detect ibeacon on iphone 6
您好，我的以下代码在 iPod touch 5 上运行良好，但相同的代码在 iPhone6 上不起作用，我对同一问题进行了研究，但没有发现任何有用的东西。两个设备都有最新的 iOS。
两个设备都有iOS8

我怀疑您的 iPhone 存在授权问题。设置断点或添加 NSLog 语句以确保调用此行：
[self.locationManager requestAlwaysAuthorization];
你收到提示了吗？如果没有，请卸载并重新安装。
此外，检查 phone 上启用了蓝牙和位置服务的设置，并检查您的应用程序的设置以查看是否确实为它启用了位置服务。
您需要设置其中之一
NSLocationAlwaysUsageDescription
要么
NSLocationWhenInUseUsageDescription 请求位置更新时（即使使用 iBeacons）。
如果不这样做，在 iOS 8 中，这将无声地失败。
