Description of error is below:
Error Domain=com.apple.LocalAuthentication Code=-1000 "Pending UI mechanism already set." UserInfo=0x17406b0c0 {NSLocalizedDescription=Pending UI mechanism already set.}
I am also trying Apple's Sample Example app and getting same error. Previously it was working fine, but it has stopped working suddenly ad not working. Please help.
I am using iPhone 6 with iOS 8.1
This code just worked fine for me.
LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = #"String explaining why app needs authentication";
if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
[myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:myLocalizedReasonString
reply:^(BOOL success, NSError *error) {
if (success) {
// User authenticated successfully, take appropriate action
NSLog(#"User authenticated successfully, take appropriate action");
} else {
// User did not authenticate successfully, look at error and take appropriate action
NSLog(#"User did not authenticate successfully, look at error and take appropriate action");
}
}];
} else {
// Could not evaluate policy; look at authError and present an appropriate message to user
NSLog(#"Could not evaluate policy: %#",authError);
}
Don't forget to import Local Authentication framework <LocalAuthentication/LAContext.h>. Hope this will solve your issue.
Try rebooting your phone.
I also started getting this error and decided to see if other apps were affected. I have both Dropbox and Mint set up for Touch ID. Sure enough Touch ID wasn't working for them either and they were falling back to passcodes.
I rebooted my phone and it started working again, so it would seem the Touch ID can bug out and stop working. I'm on iOS 8.2 btw.
I guess the proper way to handle this condition is like those apps do and fallback to password / passcode.

I tried to get the user details using MSGraph SDK in iOS using below API method. Iam successfully received the user details all the time. But when user charged their password or update their credentials, i received the oauthConnection Error: only in log. And i didn't receive any call back in the below API. Why it is not responding back when any kind of error occurred? Please help me. Thanks in advance.
[MSGraphClient setAuthenticationProvider:self.authProvider.authProvider];
self.graphClient = [MSGraphClient client];
[[[self.graphClient me]request]getWithCompletion:^(MSGraphUser *response, NSError *error) {
if(!error){
// Im able to get back here
}
else{
//Im not received any call back here when user changed their password or any error occurred.
[self.authProvider disconnect];
}
}];`
I am kinda new to MS Graph, so I might be missing something, but your graphClient declaration seems a little bit poor to me.
Try to download this sample: https://github.com/Azure-Samples/active-directory-dotnetcore-daemon-v2
And check it's declaration of graphClient.
You might be missing the part which refreshes the token?
I am trying to pin an image to pinterest. However, when I tried to authenticate the user, it fails.
I am calling the following code on button click, which takes me to pinterest app and the authentication dialog is shown,
[[PDKClient sharedInstance] authenticateWithPermissions:#[PDKClientReadPublicPermissions,
PDKClientWritePublicPermissions,
PDKClientReadPrivatePermissions,
PDKClientWritePrivatePermissions,
PDKClientReadRelationshipsPermissions,
PDKClientWriteRelationshipsPermissions]
withSuccess:^(PDKResponseObject *responseObject)
{
PDKUser *user = [responseObject user];
NSLog(#"%# authenticated!", user.firstName);
} andFailure:^(NSError *error) {
NSLog(#"authentication failed: %#", error);
}];
Also nothing prints in the console. I am unable to access the responseObject inside the block.
when I click okay, the authentication fails.
I have no idea where I could be wrong. I followed the steps mentioned in the pinteret/Developers . Can anyone guide me in the right way?
Probably there is an error in the callback URL you are passing and /or which is provided by you in the app settings. Check that Url, as a recommendation.
I am trying to implement Touch ID authentication on my app and I want to fall back to password if it fails (or not available).
Here is my code:
LAContext *ctx = [[LAContext alloc] init];
[ctx evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:#"Authenticate to access." reply:^(BOOL success, NSError *error) {
if(success){
[...]
}else if(error.code != LAErrorUserFallback){
[...] //error handler
}
}];
When I auth with Touch ID, success is called. When I can't auth after 3 touches, error handler is called. No problem up to here. But when I tap Enter Password it should display enter password screen, but nothing happens. How do I display the enter password screen?
you should use LAPolicyDeviceOwnerAuthentication instead LAPolicyDeviceOwnerAuthenticationWithBiometrics for both LAContext`s Method
evaluatePolicy:
localizedReason:kReasonTitle:
reply
and
canEvaluatePolicy:
error:
LAPolicyDeviceOwnerAuthentication:
If Touch ID is available, enrolled and not locked out, user is asked for it first, otherwise they are asked to enter device passcode That will display the enter password screen.
You should first check to see if TouchID is available by calling LAContext's [canEvaluatePolicy:error:] method, which will return NO if TouchID isn't available.
And LAErrorUserFallback is for YOUR app's own Password (authentication) scheme, not the devices. More information can be found here in this related question.
Use LAPolicyDeviceOwnerAuthentication instead of LAPolicyDeviceOwnerAuthenticationWithBiometrics.
It will first prompt for Touch ID if available and enroll it for the device. If you used Touch ID 3 times incorrectly, then the "Enter passcode" button will get displayed. After tapping that button, the device passcode screen will show up.
I'm using the dropbox SDK to save file to a user's dropbox account.
When the user taps 'save to dropbox' button for the first time, a popup window pops up and the user is required to login onto their dropbox account. I then upload a file to their dropbox account using uploadFile method provided by the SDK. However, the first time, it gives me the error:
DropboxSDK: error making request to /1/files_put/dropbox/sampleFile.pdf - (401) Authentication failed
When I close the app and try again, it successfully uploads the file.
What may be causing the app to behave so strangely?
I had the same issue and it turned out that I initialized my DBRestClient from viewDidLoad like the Dropbox docs say, but since that happens before the dropbox account is linked the restClient is not properly set.
This can be easily fixed re-initializing your restClient or even better by using the following way to access your restClient.
-(DBRestClient*)restClient{
if(_restClient == nil){
_restClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
[_restClient setDelegate:self];
}
return _restClient;
}
I got same error, use this code in your app hope this will help you.
if([[DBSession sharedSession] isLinked])
{
//Do your drop box work here...
}
else
{
//If not linked then start linking here..
[[DBSession sharedSession] linkFromController:self];
}
I am trying out adding facebook integration in an app using the new (beta) facebook ios sdk 3.0. All I would like to is post a status update to facebook. I used a FBLoginView to login to facebook. I put my app id in the plist as instructed on facebook. I put in some code to post to facebook.
(void)viewDidLoad
{
[super viewDidLoad];
NSArray *perms;
perms = [NSArray arrayWithObjects:#"status_update", nil];
FBLoginView *loginview =
[[FBLoginView alloc] initWithPermissions:perms];
loginview.frame = CGRectOffset(loginview.frame, 5, 5);
loginview.delegate = self;
[self.view addSubview:loginview];
// Do any additional setup after loading the view, typically from a nib.
}
- (IBAction)poststatus:(UIButton *)sender {
NSString *message = [NSString stringWithFormat:#"Test staus update"];
[FBRequestConnection startForPostStatusUpdate:message
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:message result:result error:error];
}];
}
- (void)showAlert:(NSString *)message
result:(id)result
error:(NSError *)error {
NSString *alertMsg;
NSString *alertTitle;
if (error) {
alertMsg = error.localizedDescription;
alertTitle = #"Error";
} else {
NSDictionary *resultDict = (NSDictionary *)result;
alertMsg = [NSString stringWithFormat:#"Successfully posted '%#'.\nPost ID: %#",
message, [resultDict valueForKey:#"id"]];
alertTitle = #"Success";
}
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle
message:alertMsg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
The odd thing is, this code works ONCE. After authenticating the user for the first time, I can post ONE status update successfully. After that, all subsequent attempts will fail with a FBiOSSDK error 5 (in the console, Error: HTTP status code:400). The only way to fix this is to remove the app from the facebook account and re-authenticate. I'm not sure what the problem is. I looked online for solutions but couldn't find anything. If anyone knows how to fix this, please let me know. Thanks
com.facebook.sdk error 5 is always irritating while working with Facebook iOS sdk. Most of the times it comes with addional in console Error: HTTP status code:400. Its a perception that there is a bug in Facebook iOS sdk that produces this error randomly. I think this error occurs for some certain reasons and sdk do not provide actual reason of error when it occurs.
Several Possible Reasons
Every request in sdk is accomplished with completion blocks that we actually pass as argument in completionHandler. This error occurs when a block is in progress and made another request. A simple example might be If you have written request to post on Facebook (startForPostStatusUpdate::) on some button action. On single button tap it would work fine but if you double tap on button it will throw this error com.facebook.sdk error 5
If you are trying to post when your current session is not opened. e.g. Once sign in with Facebook then kill the app then reopen and then try to share on Facebook, Result -> com.facebook.sdk error 5. In this case try to reopen session using
Facebook do not allow same status to be posted repeatedly, they think it might be some kind of spam e.g. If you are trying to update status and you have hard coded a string lets say #”This is a test status update” you are posing again and again. After 5 to 10 attempts they wont allow you to do anymore. Resulting com.facebook.sdk error 5. If this is the scenario you should change your status string and try updating.
Facebook has defined a limit for a particular user to post status using sdk. e.g If you are trying to update status and you have done lets say 15 to 20 status updates. They wont let you do more Resulting -> com.facebook.sdk error 5. In this scenario try to unauthorize the app from your Facebook account and reauthorize it OR try using other Facebook account
It seems there might be no answer to the issue. I have checked FB samples coming with SDK, in these examples also the same error happens. So it means after few status updates (15-20) Facebook reaches limits for that particular user. If you log-out for that user and log-in as another user, you can successfully post.
If I will find any extension to limit settings I will reply.
Also Facebook doesn't allow for the same Post.
Use a proxy !
FB ios SDK is just a wrap to an HTTP request to graph.facebook.com/....?access_token=.....
So you can easily replicate the request or use an HTTP proxy to see the real server answer (which is not error 5 !).
