I am using the following code to ask the permission from addressbook and save it to app's UserDefaults.
if (ABAddressBookRequestAccessWithCompletion != NULL)
{
// we're on iOS 6
ABAddressBookRef addressBookRef = ABAddressBookCreate();
ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
accessgranted = granted;
if(accessgranted)
{
[self saveaddressbookpermission:accessgranted];
[NSThread detachNewThreadSelector:#selector(startbgprocess) toTarget:self withObject:nil];
}
});
CFRelease(addressBookRef);
}
else {
// we're on iOS 5 or older
accessgranted = YES;
[self saveaddressbookpermission:accessgranted];
NSLog(#"in iOS 5");
[NSThread detachNewThreadSelector:#selector(startbgprocess) toTarget:self withObject:nil];
}
The issue is when i try to Reset the privacy settings using Setting->General->Reset -> Reset Location & privacy, but if i try to Change the Privacy Settings from Settings->Privacy-> and switch OFF the permissions from there then my app crashes. How can i handle this situation. Please let me know if any other information required as i am not able to find anything regarding this.

I have an iPhone App in the app store which is using Touch ID. If Touch ID is enabled, the user is authenticated with it, else user needs to enter his PIN to login to the application.
After IOS 10.1 release, when I checked the crash report, the crash count has increased. From the crash report, it is pointing on [UIApplication _cachedSystemAnimationFenceCreatingIfNecessary:] and when I opened the app in Xcode, it is focussing on [self dismissViewControllerAnimated:YES completion:nil];.
The code I have written is as below:
-(void) showTouchIDAuthentication{
LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = #"Authenticate using your finger to access My Account Menu.";
if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
[myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:myLocalizedReasonString
reply:^(BOOL success, NSError *error) {
if (success) {
NSLog(#"User is authenticated successfully");
[self dismissViewControllerAnimated:YES completion:nil];
} else {
}];
}
}
When I tested in iPhone 6, IOS 10, everything is working fine. Don't know how to simulate the issue.
Can anyone please figure out if I am missing something? Please help me out in resolving this crash issue.
Usually completion handlers are not running on main thread. All UI related stuff must be done on main thread (including dismissing a view controller).
I suggest to add the dismiss line on a main thread block like this:
-(void) showTouchIDAuthentication{
LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = #"Authenticate using your finger to access My Account Menu.";
if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
[myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:myLocalizedReasonString
reply:^(BOOL success, NSError *error) {
if (success) {
NSLog(#"User is authenticated successfully");
[[NSOperationQueue mainQueue] addOperationWithBlock:^ {
[self dismissViewControllerAnimated:YES completion:nil];
}];
} else {
}];
}
}
My app was rejected by the apple review team. According to them the reason is
"17.1: Apps cannot transmit data about a user without obtaining the user's prior permission and providing the user with access to
information about how and where the data will be used.Specifically,
your app accesses the Users contacts with out requesting permission
first"
But, I have used **NSContactsUsageDescription** key in my info.plst to specify the reason of using contacts in my app.
What should I have to do additionally for get permission?
In iOS 6 You Need to use Address-book permission request iphone to access it's Device Contact:-
method of implement code like this example:
ABAddressBookRef addressBook;
if ([self isABAddressBookCreateWithOptionsAvailable]) {
CFErrorRef error = nil;
addressBook = ABAddressBookCreateWithOptions(NULL,&error);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
// callback can occur in background, address book must be accessed on thread it was created on
dispatch_async(dispatch_get_main_queue(), ^{
if (error) {
} else if (!granted) {
} else {
// access granted
[self GetAddressBook];
}
});
});
} else {
// iOS 4/5
[self GetAddressBook];
}
You have to ask user whether your application can access your Address book. This feature is implemented in iOS 6.0 and above.
You Can try this code Snippet:
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
in - viewWillAppear:
// Asking access of AddressBook
// if in iOS 6
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"6.0"))
{
// Request authorization to Address Book
addressBook_ = ABAddressBookCreateWithOptions(NULL, NULL);
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined)
{
ABAddressBookRequestAccessWithCompletion(addressBook_, ^(bool granted, CFErrorRef error)
{
if (granted == NO)
{
// Show an alert for no contact Access
}
});
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized)
{
// The user has previously given access, good to go
}
else
{
// The user has previously denied access
// Send an alert telling user to change privacy setting in settings app
}
}
else // For iOS <= 5
{
// just get the contacts directly
addressBook_ = ABAddressBookCreate();
}
My distribution profile does not allow me to access contacts of my iPhone, Do I need to get some special permission from apple? My developer profile works well i.e it can access the contacts of my phone whereas distribution profile denies it. And it is working well in simulator also both in ios 5 simulator as well as iOS 6 simulator.
thanks in advance..

Ok, the above code is what I am trying to implement. But this code is giving me two errors. The first one is property permission not found in Facebook and second one is instance authorize authorizeWithFBAppAuth: not found.This is share kit 2.0 so maybe this will not work on it, but I need to stop the Facebook app popping up. P.S. I am a Sharekit noob.
- (void)authorize:(NSArray *)permissions {
// if we already have a session, git rid of it
[self.session close];
self.session = nil;
[self.tokenCaching clearToken];
self.session = [[[FBSession alloc] initWithAppID:_appId
permissions:permissions
urlSchemeSuffix:_urlSchemeSuffix
tokenCacheStrategy:self.tokenCaching]
autorelease];
[self.session openWithCompletionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
// call the legacy session delegate
[self fbDialogLogin:session.accessToken expirationDate:session.expirationDate];
break;
case FBSessionStateClosedLoginFailed:
{ // prefer to keep decls near to their use
// unpack the error code and reason in order to compute cancel bool
NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
BOOL userDidCancel = !errorCode && (!errorReason ||
[errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
// call the legacy session delegate
[self fbDialogNotLogin:userDidCancel];
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
}];
}
This code above is the original that came with share kit 2.0, if there is a way to stop Facebook app popping up in the above code please let me know.
Use like below:
- (void)authorize:(NSArray *)permissions
{
self.permissions = permissions;
[self authorizeWithFBAppAuth:NO safariAuth:YES];
}
And then check.
I am using Facebook iOS SDK3.0 (client is not ready to move to 3.1 yet), and have been having trouble to get FBSession to be at the FBSessionStateCreatedTokenLoaded when the app returns to the foreground after a longer period of time (close to a day); I don't have issue if I just send the app to background and come back to the foreground after a minute or two
my code is as follow, please let me know if I should provide further information; I have this issues across devices (4, 4S, 5) and iOS version (4.3, 5.0, 5.1, 6.0)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
if (![self openSessionWithAllowLoginUI:NO]) {
// still allow loading the public feed even though user is not logged in (the view controller will have a login button overlay)
[[self pictureFeedVC] loadFeed];
}
...
}

{
DEBUGLog(#"didBecomeActive");

//Dismiss login view controller
if ([self.tabBarController modalViewController]) {
[self.tabBarController dismissModalViewControllerAnimated:NO];
}
[FBSession.activeSession close];
}
}

if (allowLoginUI || (session.state == FBSessionStateCreatedTokenLoaded)) {
[FBSession setActiveSession:session];
[session openWithCompletionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
result = session.isOpen;
}
return result;
}
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState)state error:(NSError *)error
{
DEBUGLog(#"changed FB state");
switch (state) {
case FBSessionStateOpen:
if (!error) {

[[self pictureFeedVC] loadFeed];
}
break;
case FBSessionStateClosed:

case FBSessionStateClosedLoginFailed:
DEBUGLog(#"FBSessionStateClosedLoginFailed");
[session closeAndClearTokenInformation];
[self.tabBarController showFBLoginView];
break;
default:
break;
}
}
I am having problem where after extended period in the background, the DEBUGLog(#"FBSession is Open? %#",FBSession.activeSession.isOpen ? #"YES" : #"NO"); in applicationDidBecomeActive: will print a NO
more info: this app relies on Facebook login entirely, it uses facebook user ID to identify users, therefore for lots of actions I need to pass the Facebook access token so that the server can get the facebook user ID even though a lot of times those actions does not require api calls to facebook (besides getting the user ID from the access token of course). My other question is whether I need to actively do something to refresh the token or do something keep the FBSession open (if so, how?), would that be the reason why the FBSession.activeSession might not be in an open state when I return to foreground?
Thanks much in advance!
