I use below code to access contacts in my iOS application. It was working fine in iOS<10 but with Xcode 8 and iOS 10 it crashes:
- (void)btcContacts_tap {
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
if (granted) {
_addressBookController = [[ABPeoplePickerNavigationController alloc] init];
[[_addressBookController navigationBar] setBarStyle:UIBarStyleBlack];
_addressBookController.delegate = self;
[_addressBookController setPredicateForEnablingPerson:[NSPredicate predicateWithFormat:#"%K.#count > 0", ABPersonPhoneNumbersProperty]];
[_addressBookController setPeoplePickerDelegate:self];
[self presentViewController:_addressBookController animated:YES completion:nil];
}
else {
dispatch_async(dispatch_get_main_queue(), ^{
[self showMessage:NSLocalizedStringFromTable(#"PLEASE_GRANT_CONTACTS", LIApplicationLanguage(), nil) andAdvertise:#"" andService:nil andTransactionState:kTTTransactionStateInfo];
});
}
});
}
I have set NSSetUncaughtExceptionHandler to a method for logging the crash report but even the exception handler is not calling...
Does someone else faced this problem too?
iOS 10:
You need to put the NSContactsUsageDescription in your plist. Like:
<key>NSContactsUsageDescription</key>
<string>$(PRODUCT_NAME) uses photos</string>
See all usage descriptions here.
Use CNContactStore , ABAddressBookRequestAccessWithCompletion is depreciated.

I am making iOS 9 Safari AdBlocker app.
I am using the module of AdBlockPlusSafari.
App works good on simulator.
But when try to run it on device(iPhone6), it fails to reload contentBlocker.
[SFContentBlockerManager
reloadContentBlockerWithIdentifier:self.contentBlockerIdentifier
completionHandler:^(NSError *error) {
if (error) {
NSLog(#"Error in reloadContentBlocker: %#", error);
}
dispatch_async(dispatch_get_main_queue(), ^{
wSelf.reloading = NO;
[wSelf checkActivatedFlag];
if (completion) {
completion(error);
}
});
}];
it gives error
Error Domain=ContentBlockerErrorDomain Code=3 "(null)"
It caused by accessing the values in NSUserDefault (App Group).
- (instancetype)init
{
if (self = [super init])
{
_bundleName = [[[[[NSBundle mainBundle] bundleIdentifier] componentsSeparatedByString:#"."] subarrayWithRange:NSMakeRange(0, 2)] componentsJoinedByString:#"."];
NSString *group = [NSString stringWithFormat:#"group.%#.%#", _bundleName, #"AdBlockerPro"];
NSLog(#"Group name: %#", group);
_adblockProDetails = [[NSUserDefaults alloc] initWithSuiteName:group];
[_adblockProDetails registerDefaults:
#{ AdblockProActivated: #NO,
AdblockProEnabled: #YES
}];
_enabled = [_adblockProDetails boolForKey:AdblockProEnabled];
_activated = [_adblockProDetails boolForKey:AdblockProActivated];
}
return self;
}
The App Group name in host app and safari extension is same.
But in Safari extension, when app accesses the setting in NSUserDefault, it gives me the error.
In Project setting/Capabilities, I did all for App Group. In app id, it involves app group name exactly.
This happens on only device. On simulator, it works good. I can't find the reason of this error.
Please help me if you are experienced this.
Looking forward to your help.
I found the reason myself.
I have put something (NSMutableDictionary) in app group container and did something to write file to extension bundle.
It is prohibited by Apple.
So I deleted all from AdBlockManager (interacts with app group) except flag variables (Boolean type).
And I proceeded the file management using NSFileManager.

Finally, app extension is working for me on device.
Good luck!
My IDE show warning "Obsolete: Deprecated in iOS 7.0" this methods:
(GKScore) ReportScore()
(GKAchievement) ReportAchievement()
This methods it works on iOS 7, but use not problem? Exist other methods on iOS 7?
Thanks!
I used this method to report score in game center and it works.
-(void)reportScore
{
if(isIOS7)
{
// Create a GKScore object to assign the score and report it as a NSArray object.
GKScore *score = [[GKScore alloc] initWithLeaderboardIdentifier:_leaderboardIdentifier];
score.value = _score;
[GKScore reportScores:#[score] withCompletionHandler:^(NSError *error) {
if (error != nil) {
NSLog(#"score reporting error : %#", [error localizedDescription]);
}
else
{
NSLog(#"score reported.");
}
}];
}
else
{
GKScore *scoreReporter = [[GKScore alloc] initWithCategory:_leaderboardIdentifier];
scoreReporter.value = _score;
scoreReporter.context = 0;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
// Do something interesting here.
if (error != nil) {
NSLog(#"score reporting error : %#", [error localizedDescription]);
}
else
{
NSLog(#"score reported.");
}
}];
}
}
Objective-C methods start with a lower-case method. They are not called with rounded brackets. So, I:
opened the documentation for GKScore;
looked for anything deprecated and found -reportScoreWithCompletionHandler:;
saw that +reportScores: withCompletionHandler: isn't deprecated.
And saw pretty much the same thing with the singular instance method being deprecated in favour of the collection class method in GKAchievement.
So: just use the collection methods. Deprecated methods hang around being unsupported for a while and then disappear. You can find out what's currently supported, very very quickly, by reading the documentation.
I apologizes if this question is repeated but i had hard time trying to display route between two places using MKDirectionsRequest.
MKDirectionsRequest *request = [[MKDirectionsRequest alloc] init];
request.source = [MKMapItem mapItemForCurrentLocation];
request.transportType = MKDirectionsTransportTypeAny;
request.destination = _dstItem;
request.requestsAlternateRoutes = YES;
MKDirections *directions = [[MKDirections alloc] initWithRequest:request];
// __block typeof(self) weakSelf = self;
[directions calculateDirectionsWithCompletionHandler:
^(MKDirectionsResponse *response, NSError *error) {
//stop loading animation here
if (error) {
NSLog(#"Error is %#",error);
} else {
//do something about the response, like draw it on map
MKRoute *route = [response.routes firstObject];
[self.mapView addOverlay:route.polyline level:MKOverlayLevelAboveRoads];
}
}];
MKDirectionsResponse alway returns nil with error description
Error Domain=MKErrorDomain Code=5 "Directions Not Available"
UserInfo=0x1700f1c80 {NSLocalizedFailureReason=A route to the nearest road cannot be determined.,
MKErrorGEOError=-403, MKDirectionsErrorCode=6, NSLocalizedDescription=Directions Not Available}
MKDirectionsRequest is the right api to find route between two points. It seems Apple has not added route feature for India yet.
Error Domain=MKErrorDomain Code=5 "Directions Not Available"
You are most likely to get this error if the location doesn't belong to any of the countries in this list: http://www.apple.com/ios/feature-availability/#maps-directions
While on iOS simulator, you can easily customize your current location. Two ways to do it:
iOS Simulator -> 'Debug' tab -> Location -> {Choose}
Xcode -> 'Debug' tab -> Simulate Location -> {Choose}
i am getting same error message .if you are providing lat long of india it will not work because apple has not added rout feature for india yet try with different lat long hope it will work.i tried same and it is working for me.
I was getting same Error. I still do not know the best solution yet. But I created one button on map with refresh and called the method i was calling from viewDidLoad() as I figured, my method is returning immediately with error before even calculating the address from viewDidLoad().
My guess is, viewDidLoad() should get finished in some specific predefined time.
So,
<hr/> `-(IBAction)refreshRoute:(id)sender {
[self routeCalculate];
}`
<hr/>
instead of
<hr/>
-(void)viewDidLoad {
[super viewDidLoad];
_manager = [[CLLocationManager alloc]init];
[_manager requestWhenInUseAuthorization];
[_manager requestAlwaysAuthorization];
_manager.desiredAccuracy = kCLLocationAccuracyBest;
_manager.distanceFilter =kCLDistanceFilterNone;
[_manager requestWhenInUseAuthorization];
[_manager requestAlwaysAuthorization];
[_manager startUpdatingLocation];
[_manager delegate];
self.pinMap.delegate = self;
// [self routeCalculate]; ***** This Call ****
}
<hr/>
I'm using what seems to be a simple invocation of the NSFileVersion class method removeOtherVersionsOfItemAtURL: inside a coordinated writing block for some iCloud conflict resolution.
When my devices go into 'spaz mode', which is a technical term for repeatedly opening and closing the application on a few devices, an EXC_BAD_ACCESS exception is thrown internally. Code snippet:
- (void)compareVersionChanges:(NSFileVersion *)version {
if (![DataLoader iCloudPreferenceEnabled]) {
NSLog(#"Ignoring iCloud changes (version comparison) based on user preference");
return;
}
NSLog(#"compareVersionChanges");
dispatch_queue_t aQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(aQueue, ^(void) {
NSError *readError = nil;
NSFileCoordinator *coordinator = [[NSFileCoordinator alloc] initWithFilePresenter:(id)self];
[coordinator coordinateReadingItemAtURL:[version URL] options:0 error:&readError byAccessor:^(NSURL *newURL) {
DataContext *loadedContext = nil;
NSData *data = [NSData dataWithContentsOfURL:newURL];
NSError *e = nil;
loadedContext = [self convertXmlDataToContext:data error:&e];
if (e) {
NSLog(#"Done loading, error: %#", e);
[[DataLoader applicationDelegate] displayError:e];
loadedContext = nil;
}
if (!loadedContext) {
return;
}
id appDelegate = [DataLoader applicationDelegate];
DataContext *inMemoryContext = nil;
if (appDelegate != nil && [appDelegate respondsToSelector:#selector(context)]) {
inMemoryContext = [appDelegate performSelector:#selector(context)];
}
if (inMemoryContext) {
NSLog(#"Performing iCloud context synchronizating...");
DataContextSynchronizer *synchronizer = [[DataContextSynchronizer alloc] init];
ChangeSet *changes = [synchronizer compareLocalContext:inMemoryContext andRemoteContext:loadedContext];
if ([[changes changes] count] > 0) {
[SelectionManager disable];
#synchronized(appDelegate) {
NSLog(#"Applying synchronization changes...");
[synchronizer applyChangeSet:changes toDataContext:inMemoryContext];
NSLog(#"Synchronization changes applied");
}
[SelectionManager enable];
if ([appDelegate respondsToSelector:#selector(setSkipRefreshSave:)]) {
[appDelegate performSelector:#selector(setSkipRefreshSave:) withObject:[NSNumber numberWithBool:YES]];
}
dispatch_queue_t mainQueue = dispatch_get_main_queue();
dispatch_async(mainQueue, ^(void) {
[SelectionManager notifyListeners];
});
if ([appDelegate respondsToSelector:#selector(setSkipRefreshSave:)]) {
[appDelegate performSelector:#selector(setSkipRefreshSave:) withObject:[NSNumber numberWithBool:NO]];
}
[self save:[[DataLoader applicationDelegate] context]];
} else {
NSLog(#"No sync changes applicable.");
}
NSError *coordinateWriteRemoveError = nil;
[coordinator coordinateWritingItemAtURL:newURL options:NSFileCoordinatorWritingForDeleting error:&coordinateWriteRemoveError byAccessor:^(NSURL *theURL) {
theURL = [theURL copy];
NSError *removeOtherVersionsError = nil;
[NSFileVersion removeOtherVersionsOfItemAtURL:theURL error:&removeOtherVersionsError];
if (removeOtherVersionsError) {
NSLog(#"Error removing other versions: %#", removeOtherVersionsError);
}
}];
if (coordinateWriteRemoveError) {
NSLog(#"Error occurred coordinating write for deletion of other file versions: %#", coordinateWriteRemoveError);
}
}
}];
if (readError) {
NSLog(#"Done loading (outside block) error: %#", readError);
}
});
}
I thought a little syntax highlighting might make this easier to examine:
Link to image of code snippet and failure stack in Xcode
The error actually occurs on line 1404, and as you can see from the below screenshot, it's deep in Apple code territory.
Link to image of debugger
Before submitting a radar, I thought I'd check here to see if there's something I'm doing wrong? The extra [... copy] on line 1402 was just a quick check to make sure I'm not losing the reference to the block-provided argument, and will be removed.
Edit: An important note! I'm using ARC.
Edit 2: I've noticed that when calling:
[NSFileVersion otherVersionsOfItemAtURL:theURL]
The return value is nil, which indicates (via the documentation):
...or nil if there is no such file. The array does not contain the version object returned by the currentVersionOfItemAtURL: method.
So by checking the return value of this method before I make the call to removeOtherVersionsOfItemAtURL:, it has alleviated the issue. But I still find it strange that an EXC_BAD_ACCESS is thrown, rather than that method handling it properly.

I'll be filing a Radar and will update here when I hear back.
Having a heck of a time with this one.
I've got a super-simple Cocoa app containing one WebView, a WebScripting API defined in the page, and a single NSObject defined on that API. When I turn on the debugger tools (in the embedded WebView), I can see the API on the JavaScript window object, and I can see my "api" property defined on that -- but when I call the API's "get" method, the arguments aren't being serialized -- when the Obj-C method gets called, the arguments are missing. See below, which hopefully illustrates:
I've combed through the docs, I've (apparently) set the appropriate methods to expose everything that needs to be exposed, and I can see the method being called. There has to be something stupid I'm missing, but as a relative newbie to this environment, I'm not seeing it.
Thanks in advance for your help!
Have you set WebKitDeveloperExtras to YES in your default user defaults when you send -[NSUserDefaults registerDefaults:]?
Depending on what version of Xcode you're using you could be getting a known error. If you're using LLDB on anything but the most recent version, it might not be giving you the right variables in the debugger. The solution has been to use GDB instead of LLDB until Apple fixes the problem. But I think they fixed the problem in the latest version. I'd change the debugger to use GDB and see if you're getting the right variables in Xcode. (Product-> Edit Scheme...-> Run -> Debugger). I came across this problem in iOS, though, so I don't know its applicability to OSX. Worth a try anyway.
I originally came across the problem here: https://stackoverflow.com/a/9485349/1147934
I process javascript in the main thread of my app from a local file stored in the apps directory. I check for beginning and ending tokens for the js functions I am executing and whether the function contains a variable.
Hopefully this can give you some good ideas for your issue. You could also do alerts in the js to see if the values post correctly as you run the app (I am sure you thought of that already, but it's worth mentioning.) Happy coding! I hope this helps!
