不懂如何实现iOS指纹识别应用？其实想解决这个问题也不难，下面让小编带着大家一起学习怎么去解决，希望大家阅读完这篇文章后大所收获。

指纹识别（Touch ID）的简单应用，供大家参考，具体内容如下

1、调用

- (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  
  
  [self setupNotification];
  UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
  [button setTitle:@"点击调用" forState:UIControlStateNormal];
  [button addTarget:self action:@selector(actionDidClickButton:) forControlEvents:UIControlEventTouchUpInside];
  [button setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
  [self.view addSubview:button];
}

- (void)actionDidClickButton:(UIButton *)sender
{
  [self touchIDTest];
}
- (void)touchIDTest
{
  [TouchIDManager validateTouchID];
}

- (void)setupNotification
{
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionDidReceiveValidateTouchIDSuccess) name:ValidateTouchIDSuccess object:nil];
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionDidReceiveValidateTouchIDNotAvailable) name:ValidateTouchIDNotAvailable object:nil];
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionDidReceiveValidateTouchIDNotEnrolled) name:ValidateTouchIDNotEnrolled object:nil];
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionDidReceiveValidateTouchIDAuthenticationFailed) name:ValidateTouchIDAuthenticationFailed object:nil];
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionDidReceiveValidateTouchIDCancel) name:ValidateTouchIDCancel object:nil];
  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(actionTouchIDLockout) name:ValidateTouchIDLockout object:nil];
}
- (void)actionDidReceiveValidateTouchIDSuccess
{
  NSLog(@"%s",__func__);
}
- (void)actionDidReceiveValidateTouchIDNotAvailable
{
  NSLog(@"%s",__func__);
}
- (void)actionDidReceiveValidateTouchIDNotEnrolled
{
  NSLog(@"%s",__func__);
}
- (void)actionDidReceiveValidateTouchIDAuthenticationFailed
{
  NSLog(@"%s",__func__);
}
- (void)actionDidReceiveValidateTouchIDCancel
{
  NSLog(@"%s",__func__);
}
- (void)actionTouchIDLockout
{
  NSLog(@"%s",__func__);
}
- (void)dealloc
{
  [[NSNotificationCenter defaultCenter]removeObserver:self];
}
