本文介绍了一种在iOS应用中集成TouchID的方法。通过引入QuartzCore.framework和LocalAuthentication.framework框架，并利用Objective-C代码实现了一个简单的示例，展示了如何使用TouchID进行用户身份验证。

最近因为要做一个理财产品，所以指纹识希望加进去，就研究了下，写了段代码

先在项目中添加QuartzCore.framework和LocalAuthentication.framework

#import "ViewController.h"

#import <LocalAuthentication/LocalAuthentication.h>

@interface ViewController ()

@property (weak, nonatomic) IBOutlet UIButton *btn;

@end

@implementation ViewController

- (void)viewDidLoad

{

[super viewDidLoad];

_btn.layer.shadowColor = [UIColor grayColor].CGColor;

_btn.layer.shadowOffset = CGSizeMake(3, 2);

_btn.layer.shadowOpacity = 0.5;

_btn.center = self.view.center;

[_btn setTitle:@"Touch IDTest" forState:UIControlStateNormal];

[_btn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];

// Do any additional setup after loading the view, typically from a nib.

}

-(void)btnClick:(UIButton *)sender

{

[self TouchIDTestSuccess:^

{

NSLog(@" Touch ID ");

UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"恭喜，您通过了Touch ID身份验证" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction * cancel= [UIAlertAction actionWithTitle:@"返回" style:UIAlertActionStyleCancel handler:nil];

[alert addAction:cancel];

[self presentViewController:alert animated:YES completion:nil];

} Failure:^(NSError *error)

{

NSLog(@" Touch ID \n\(error)");

UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"抱歉，您未能通过Touch ID身份验证" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction * cancel= [UIAlertAction actionWithTitle:@"返回" style:UIAlertActionStyleCancel handler:nil];

[alert addAction:cancel];

[self presentViewController:alert animated:YES completion:nil];

} Unvilabe:^(NSError *error)

{

NSLog(@" Touch ID \n\(error)");

UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"抱歉，Touch ID不可用" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction * cancel= [UIAlertAction actionWithTitle:@"返回" style:UIAlertActionStyleCancel handler:nil];

[alert addAction:cancel];

[self presentViewController:alert animated:YES completion:nil];

}];

}

- (void)didReceiveMemoryWarning {

[super didReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}

-(void)TouchIDTestSuccess:(void(^)())successed Failure:(void(^)(NSError * error))failured Unvilabe:(void(^)(NSError * error))Unvilabe

{

LAContext * lauth = [[LAContext alloc]init];

NSError * error = nil;

BOOL isTouchAvalible = [lauth canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error];

if (isTouchAvalible)

{

[lauth evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"需要验证您的指纹来确认您的身份信息" reply:^(BOOL success, NSError * _Nullable error)

{

if (success)

{

if (successed)

{

successed();

}

else

{

if (failured)

{

failured(error);
