iOS要实现指纹识别,首先要导入LocalAuthentication

let authenticationContext = LAContext(); var error:NSError? = nil; if (authenticationContext.canEvaluatePolicy(LAPolicy.deviceOwnerAuthenticationWithBiometrics,error: &error)) { authenticationContext.evaluatePolicy(LAPolicy.deviceOwnerAuthenticationWithBiometrics,localizedReason: "需要验证你的指纹确认信息",reply: { (successed,error) in if (successed) { print("验证成功") }else { print("验证失败") } }) }
