Integrate Office-365-SDK-for-iOS - ios

Question

I am creating an iOS application in which I am integrating Office-365-SDK-for-iOS for import contacts from outlook365.I am successfully able to authenticate with Microsoft Azure. But when I am fetching user and user's contacts then following error is coming-
Error Domain=Error in the Request Code=401 "The operation couldn’t be completed. (Error in the Request error 401.)
Here is my code for authentication and get client
//Acquire access and refresh tokens from Azure AD for the user.
-(void)acquireAuthTokenWithResourceId:(NSString *)resourceId completionHandler:(void (^)(BOOL authenticated))completionBlock
{
ADAuthenticationError *error;
self.authContext = [ADAuthenticationContext authenticationContextWithAuthority:OutlookAuthority error:&error];
[self.authContext acquireTokenWithResource:OutlookRsourceId
clientId:OutlookClientId
redirectUri:[NSURL URLWithString:OutlookRedirectUrl]
completionBlock:^(ADAuthenticationResult *result)
{
if (AD_SUCCEEDED != result.status)
{
completionBlock(NO);
}
else
{
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:result.tokenCacheStoreItem.userInformation.userId
forKey:#"LogInUser"];
[userDefaults synchronize];
self.dependencyResolver = [[ADALDependencyResolver alloc] initWithContext:self.authContext
resourceId:OutlookRsourceId
clientId:OutlookClientId
redirectUri:[NSURL URLWithString:OutlookRedirectUrl]];
completionBlock(YES);
}
}];
}
- (void) getClient:(void (^) (MSOutlookServicesClient *))callback
{
OutlookAuthManager* authenticationController = [OutlookAuthManager sharedInstance];
[authenticationController acquireAuthTokenWithResourceId:OutlookRsourceId completionHandler:^(BOOL authenticated)
{
if (authenticated)
{
callback([[MSOutlookServicesClient alloc] initWithUrl:#"https://outlook.office365.com/api/v1.0" dependencyResolver:[authenticationController dependencyResolver]]);
}
else
{
NSLog(#"Error in authentication");
}
}];
}
And following I am getting user-
[[OutlookAuthManager sharedInstance] getClient:^(MSOutlookServicesClient *client)
{
NSURLSessionTask* task = [[client getMe] readWithCallback:^(MSOutlookServicesUser *user, NSError *error)
{
if(error == nil)
{
dispatch_async(dispatch_get_main_queue(),
^{
NSLog(#"------>%#",user.DisplayName);
NSLog(#"------>%#",user.Alias);
NSLog(#"------>%#",user.Id);
NSLog(#"------>%#",user.MailboxGuid);
});
}
else
{
[client.resolver.logger logMessage:error.description withLevel:LOG_LEVEL_ERROR];
}
}];
[task resume];
}];
But That error is coming here.
Please help me
Thanks

Start by validating your access token. Since it's a 401 it's likely a problem there.
