ios – 如何在设备中检查安全区域是否可用

概述我们知道安全的Enclave是一个在Apple A7中制造的协处理器,它在A7及更高版本中可用,但它在iOS 9 kSecAttrTokenIDSecureEnclave中公开使用,但我们如何检查某些设备是否支持安全区？ 谢谢 我没找到任何所以我做了自己的检查： + (BOOL) isDeviceOkForSecureEnclave{ double OSVersionNumber 我们知道安全的Enclave是一个在Apple A7中制造的协处理器,它在A7及更高版本中可用,但它在iOS 9 kSecAttrTokenIDSecureEnclave中公开使用,但我们如何检查某些设备是否支持安全区？
谢谢解决方法 我没找到任何所以我做了自己的检查：

检查触摸ID

- (BOol)canAuthenticateBytouchID {if ([LAContext class]) {    return [[[LAContext alloc] init] canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:nil];}return YES;}
