iOS指纹验证TouchID应用学习教程2

第五步

在上述调用指纹验证成功后，必须得实现它的回调函数，在成功或者失败的方法中写上你需要执行的代码。

//TouchID验证成功
- (void) WJTouchIDAuthorizeSuccess {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES)
 {
 [MBProgressHUD showText:@"成功开启指纹解锁" view:self.view];
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }else{
 [MBProgressHUD showText:@"指纹解锁关闭成功" view:self.view];
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }
}

//TouchID验证失败
- (void) WJTouchIDAuthorizeFailure {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES){
 self.touchIDSwitch.on = NO;
 [MBProgressHUD showText:@"指纹解锁开启失败" view:self.view];
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }else
 {
 self.touchIDSwitch.on = YES;
 [MBProgressHUD showText:@"指纹解锁关闭失败" view:self.view];
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }
}

//取消TouchID验证 (用户点击了取消)
- (void) WJTouchIDAuthorizeErrorUserCancel {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES){
 self.touchIDSwitch.on = NO;
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }else
 {
 self.touchIDSwitch.on = YES;
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }
}

//在验证的TouchID的过程中被系统取消 例如突然来电话、按了Home键、锁屏
- (void) WJTouchIDAuthorizeErrorSystemCancel {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES){
 self.touchIDSwitch.on = NO;
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }else
 {
 self.touchIDSwitch.on = YES;
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }
}

//多次连续使用Touch ID失败，Touch ID被锁，需要用户输入密码解锁
- (void) WJTouchIDAuthorizeLAErrorTouchIDLockout {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 [MBProgressHUD showText:@"验证失败" view:self.view];
}

//当前软件被挂起取消了授权(如突然来了电话,应用进入前台)
- (void) WJTouchIDAuthorizeLAErrorAppCancel {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES){
 self.touchIDSwitch.on = NO;
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }else
 {
 self.touchIDSwitch.on = YES;
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }
}

//当前软件被挂起取消了授权 (授权过程中,LAContext对象被释)
- (void) WJTouchIDAuthorizeLAErrorInvalidContext {
 [[NSUserDefaults standardUserDefaults]setObject:@"YES" forKey:@"touchIDISon"];
 if (self.touchIDSwitch.on == YES){
 self.touchIDSwitch.on = NO;
 [[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"TouchID"];
 }else
 {
 self.touchIDSwitch.on = YES;
 [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"TouchID"];
 }
}
