我使用触摸ID身份验证为登录应用程序制作了一个演示。 触摸ID身份验证正常，但
当我使用我的触摸ID进行身份验证时，它会根据手指扫描给我立即响应，但是在发送消息之后，需要花费很多时间来进一步处理，例如前进或显示我成功的结果。 我在代码中也使用了Switch Case语句。
- (IBAction)touchidRegistration:(id)sender {
LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = @"Authenticate using your finger";
if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
self.myHud.hidden = NO;
[myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:myLocalizedReasonString
reply:^(BOOL succes, NSError *error) {
if (succes) {
self.btnRegister.enabled = YES;
// self.myHud.hidden = YES;
self.registrationFlag = @"YES";
self.flag = @"";
self.verifiedImage.hidden = NO;
NSLog(@"flag Value is %@",self.flag);
NSLog(@"Done!!!");
[self showMessage:@"Authentication is successful" withTitle:@"Success"];
NSLog(@"User authenticated");
} else {
switch (error.code) {
case LAErrorAuthenticationFailed:
self.myHud.hidden = YES;
[self showMessage:@"Authentication is failed" withTitle:@"Error"];
NSLog(@"Authentication Failed");
break;
case LAErrorUserCancel:
self.myHud.hidden = YES;
[self showMessage:@"You clicked on Cancel" withTitle:@"Error"];
NSLog(@"User pressed Cancel button");
break;
case LAErrorUserFallback:
self.myHud.hidden = YES;
[self showMessage:@"You clicked on \"Enter Password\"" withTitle:@"Error"];
NSLog(@"User pressed \"Enter Password\"");
break;
default:
self.myHud.hidden = YES;
[self showMessage:@"Touch ID is not configured" withTitle:@"Error"];
NSLog(@"Touch ID is not configured");
break;
}
NSLog(@"Authentication Fails");
}
}];
} else {
self.myHud.hidden = YES;
NSLog(@"Can not evaluate Touch ID");
[self showMessage:@"Can not evaluate TouchID" withTitle:@"Error"];
}
}
请帮助我们或建议我任何链接我无法在这里搜索此类问题。我已经看过一个但是对于Swift，我需要目标 - C 链接： - swift - touchID takes long time to load
注意： - 我正在使用I-Phone 6设备进行测试。 提前谢谢。
答案 0 :(得分：1)
最后我得到了答案， 它的工作正常对我来说谢谢
if (succes) {
NSOperationQueue *myQueue = [[NSOperationQueue alloc] init];
[myQueue addOperationWithBlock:^{
// Background work
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
// Main thread work (UI usually)
NSMutableDictionary *userInfo = [StaticClass getTouchIdData:@"userInfo"];
if(!([userInfo count] == 0))
{
self.myHud.hidden = YES;
self.flag = @"";
TestViewController *testView = [[TestViewController alloc]initWithNibName:@"TestViewController" bundle:nil];
[testView setUserInfo:userInfo];
[self.navigationController pushViewController:testView animated:YES];
}
else
{
self.myHud.hidden = YES;
self.flag = @"YES";
self.registrationFlag = @"";
[self showMessage:@"For The First time user ,You have to login manually" withTitle:@"Error"];
self.touchIdLoginView.hidden = YES;
}
NSLog(@"User Id is %@",userInfo);
