IOS - Touch ID Authentication takes more time after loading - ios

Question

I have made one demo for login application with touch id authentication.
It is going fine with touch id authentication but,
My Problem is
When I do authentication with my touch id it gives me immediate response according the finger scans , But after messaging it took so much time for further process like move forward or display result which I have placed on success.
I have also used Switch Case Statements in my code.
Code is
- (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"];
}
}
Please help me guys or suggest me any link I do not able to search this type of problem on here.I have seen one but its for Swift,I need for OBJECTIVE - C
link:- swift - touchID takes long time to load
Note:-I am using I-Phone 6 device for testing.
Thanks in advance.

Its Working Fine For me thank you
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);
NSLog(#"Done!!!");
NSLog(#"User authenticated");
}];
}];
