#import
系统必须是8.0以后
主要用到的类是LAContext
代码如下
- (IBAction)loginAction:(id)sender {

if(![self canLocalAuthentication])
return;
LAContext *context = [[LAContext alloc] init];
context.localizedFallbackTitle = @"输入密码";
NSError *error = nil;
if([context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]){
[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"通过Home键验证手机" reply:^(BOOL success, NSError * _Nullable error) {
if(success){
[self showMessageInMainThread:@"Touch ID 验证成功"];
}else if(error){
switch (error.code) {
case LAErrorAuthenticationFailed:
[self showMessageInMainThread:@"验证失败"];
break;
case LAErrorUserCancel:
[self showMessageInMainThread:@"用户取消"];
break;
case LAErrorSystemCancel:
[self showMessageInMainThread:@"系统取消"];
break;
default:
break;
}}else{
[self showMessageInMainThread:@"当前设备不支持TouchID"];
}
}];
}
}
-(void)showMessageInMainThread:(NSString *)string
{
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"%@",string);
});
}-(BOOL)canLocalAuthentication
