iOS 添加手机密码、指纹进行安全验证

#import <LocalAuthentication/LocalAuthentication.h>

    //创建安全验证对象
    LAContext *con = [[LAContext alloc] init];
    NSError *error;
    //判断是否支持密码验证
    /**
     *  LAPolicyDeviceOwnerAuthentication 手机密码的验证正方式
     *  LAPolicyDeviceOwnerAuthenticationWithBiometrics 指纹验证方式
     */
    
    BOOL can = [con canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error];
    if (can)
    {
        [con evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"验证信息" reply:^(BOOL success, NSError * _Nullable error) {
            NSLog(@"%d,%@",success,error);
        }];
    }
