I am trying to integrate CallKit into my Voip app. I referred to the SpeakerBox sample code from Apple WWDC. I created a ProviderDelegate class and I am able to see the incoming call UI after calling reportNewIncomingCall method.
But when I tap on the "Answer"/"End" button, the respective provider delegates are not fired. What could be wrong here?
Please note that "providerDidBegin" is called when I instantiate the CallProviderDelegate.
#implementation CallProviderDelegate
- (instancetype)init
{
self = [super init];
if (self) {
_providerConfiguration = [self getProviderConfiguration];
_provider = [[CXProvider alloc] initWithConfiguration:_providerConfiguration];
[_provider setDelegate:self queue:nil];
}
return self;
}
- (void)providerDidBegin:(CXProvider *)provider {
// this is getting called
}
- (void)provider:(CXProvider *)provider performAnswerCallAction:(CXAnswerCallAction *)action {
// this is not getting called when the Answer button is pressed
}
- (void)reportNewIncomingCallWithUUID:(nonnull NSUUID *)UUID handle:(nonnull NSString *)handle
completion:(nullable void (^)(NSError *_Nullable error))completion {
CXCallUpdate *update = [[CXCallUpdate alloc] init];
update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:handle];
update.hasVideo = NO;
[_provider reportNewIncomingCallWithUUID:UUID update:update completion:^(NSError * _Nullable error) {
completion(error);
}];
}
In Caller Class:
CallProviderDelegate *providerDelegate = [[CallProviderDelegate alloc] init];
[providerDelegate reportNewIncomingCallWithUUID:[NSUUID UUID] handle:#"Raj" completion:^(NSError * _Nullable error) {
//
}];
In your "caller" class, i.e. the code in which you instantiate the CallProviderDelegate class and assign it to the providerDelegate variable, are you storing the providerDelegate object reference in an instance variable or property? If it is only being assigned to a temporary local variable, then the CallProviderDelegate object will be deallocated after the calling method finishes executing, and if the CallProviderDelegate object is deallocated then no further CXProvider delegate messages will be delivered.
I'd check that your CallProviderDelegate object is not being accidentally deallocated first.

I am using Call Kit in VOIP application (using ABTO VoIP SDK too). But I want to merge my VoiP App call history to my iPHONE recent tab. I added Call kit in my project everything was fine I am getting VoIP app call history to my iPhone recent tab. But I am facing issues while calling once I do incoming or outgoing calls I am getting callkit default screen which lead the incoming call on hold and outgoing to. Would there any way to manage callkit default screen? Would it be possible to manage two SDK at the same time??? I am using pushkit too..
Please help me to resolve this issue????
Whenever I am getting incoming call I am facing 2 calling screen one from Voip SDK and one from Call kit.. I want to manage that default screen
Quickblox webrtc video call receive method is not called .I am call to someone he accept the call and we can communicate but while he is calling me i am not geting that call.
`
- (void)didReceiveNewSession:(QBRTCSession *)session userInfo:(NSDictionary *)userInfo {
if (self.session ) {
[session rejectCall:#{#"reject" : #"busy"}];
return;
}
self.session = session;
[QBRTCSoundRouter.instance initialize];
NSParameterAssert(!self.nav);
IncomingCallViewController *incomingViewController =
[self.storyboard instantiateViewControllerWithIdentifier:#"IncomingCallViewController"];
incomingViewController.delegate = self;
incomingViewController.session = session;
incomingViewController.usersDatasource = self.dataSource;
self.nav = [[UINavigationController alloc] initWithRootViewController:incomingViewController];
[self presentViewController:self.nav animated:NO completion:nil];
}
The Quickblox webrtc video call receive method only called when the user is online so make sure you add in Your -
(Void)ViewDidLoad{
[QBRequest logInWithUserLogin:#"xxxxxx"
password:#"xxxxx"
successBlock:^(QBResponse * _Nonnull response, QBUUser * _Nullable user)
{
}];
[[QBChat instance] connectWithUser:self.user completion:^(NSError * _Nullable error) {
NSLog(#"User%#",self.user);
}];
}
It will be called.
I have a Location.m model, which I use to obtain latitude and longitude. When I have those, I call my delegate method which is implemented in my Foursquare.m model.
Location.h looks like this:
#class Location;
#protocol LocationDelegate <NSObject>
- (void)location:(Location *)loc didFinishFindingLocation:(CLLocation *)location;
#end
#interface Location : NSObject <CLLocationManagerDelegate>
#property (nonatomic, weak) id <LocationDelegate> delegate;
- (void)startLocationManager;
#end
Location.m:
#implementation Location
{
CLLocationManager *_locationManager;
BOOL _locationIsUpdated;
}
- (void)startLocationManager
{
NSLog(#"In startLocationManager");
_locationManager = [[CLLocationManager alloc] init];
_locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
_locationManager.delegate = self;
_locationIsUpdated = NO;
[_locationManager startUpdatingLocation];
}
#pragma mark - LocationManager Delegates
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
if (locations && _locationIsUpdated == NO) {
self.location = [locations lastObject];
NSLog(#"%#", _location);
_locationIsUpdated = YES;
[self.delegate location:self didFinishFindingLocation:self.location];
}
}
#end
When the delegate method is called from the Foursquare model, and I NSLog out the response in an array (called self.dataResponse). It always outputs (null) first, then all the JSON. Why does that happen? If I NSLog out dataDictionary (see code below) directly, the JSON output shows a error-code:400 and nothing is printed. Couple of milliseconds after everything is printed and seems to be working fine...
Here is a picture:
When I log the dataDictionary
Here is the delegate method implemented in Foursquare.m:
- (void)location:(Location *)loc didFinishFindingLocation:(CLLocation *)location
{
loc.delegate = self;
self.resultFromResponse = [[NSMutableArray alloc] init];
NSString *search = [NSString stringWithFormat:#"https://api.foursquare.com/v2/venues/search?ll=%f,%f&radius=2000&categoryId=4d4b7105d754a06374d81259&client_id=%#&client_secret=%#&v=%#", location.coordinate.latitude, location.coordinate.longitude, kFourdquareAPIKey, fFoursquareSecret, [Foursquare getCurrentDate]];
NSURL *url = [NSURL URLWithString:search];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSURLSessionDataTask *task = [session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSDictionary *dataDictionary = (NSDictionary *)[NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (!error) {
self.dataResponse = dataDictionary[#"response"][#"venues"];
NSLog(#"%#", self.dataResponse);
for (NSDictionary *venue in self.dataResponse) {
FSDataFromJSON *data = [[FSDataFromJSON alloc] init];
data.name = venue[#"name"];
data.phone = venue[#"phone"];
data.location = venue[#"location"];
[self.resultFromResponse addObject:data];
}
//[[NSNotificationCenter defaultCenter] postNotificationName:#"JSONRequestFinishedLoading" object:nil];
} else {
NSLog(#"%#", error.description);
}
}];
[task resume];
}
At the very end, these models is started in my MainViewController:
_location = [[Location alloc] init];
[_location startLocationManager];
_foursquare = [[Foursquare alloc] init];
[_foursquare location:_location didFinishFindingLocation:_location.location];
From what I can tell, the last line of code in your question is likely the problem:
[_foursquare location:_location didFinishFindingLocation:_location.location];
You shouldn't be calling your delegate method explicitly (before the location has been set). Instead, you should be waiting for the CLLocation callback to kick it off.
Other thoughts:
If the Location class has a .location property, I think that's confusing.
Location.m is not a model, it's the file containing the class implementation. I'd say the Location class is a model.
You could simplify your delegate method as didFindLocation:(Location *)location since you can get the CLLocation in the method as location.location.
What are the three most important factors in real estate? location.location.location!
I am trying to create a real time multiplayer game using game center, programatically. My problem is the lack of documentation since the old inviteHandler has been deprecated.
The first thing I do is the authentication:
- (void) authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
__weak GKLocalPlayer *blockLocalPlayer = localPlayer;
localPlayer.authenticateHandler = ^(UIViewController *receivedViewController, NSError *error)
{
if (receivedViewController != nil)
{
[self presentViewController:receivedViewController animated:YES completion:nil];
}
else if (blockLocalPlayer.isAuthenticated)
{
[blockLocalPlayer registerListener:self];
}
};
}
After that, I start the invitation process as it says on apple docs.
- (void)invitePlayers:(NSArray *)friendsArray
{
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = friendsArray;
request.inviteMessage = #"Your Custom Invitation Message Here";
request.inviteeResponseHandler = ^(NSString *playerID, GKInviteeResponse response)
{
[self updateUIForPlayer: playerID accepted: (response == GKInviteeResponseAccepted)];
};
}
I implemented the following methods, but they are never called:
- (void)player:(GKPlayer *)player didAcceptInvite:(GKInvite *)invite
- (void)player:(GKPlayer *)player didRequestMatchWithPlayers:(NSArray *)playerIDsToInvite
How can I let the other player receive the invite and respond to it? On the apple docs the old deprecated way is demonstrated.
Try to register first for a GKLocalPlayer listener in order to get called via this methods:
- (void)registerListener:(id<GKLocalPlayerListener>)listener
which should conforms to this protocol:GKLocalPlayerListener
I'm creating an app which communicates alot with a server. I want to make sure I have only 1 connection at a time - only 1 request pending. I want so that if I try to send another request, It will wait until the current one is finished before sending the next.
How can I implement This?
Tnx!
I don't know of any automatic mechanism to do this. So you have to write a new class yourself (let's call it ConnectionQueue):
Basically, instead of a creating the NSURLConnection directly, you call a method of your ConnectionQueue class (which should have exactly one instance) taking the NSURLRequest and the delegate as a parameter. Both are added to a queue, i.e. a separate NSArray for the requests and the delegates.
If the arrays contains just one element, then no request is outstanding and you can create a NSURLConnection with the specified request. However, instead of the delegate passed to the method, you pass your ConnectionQueue instance as the delegate. As a result, the connection queue will be informed about all actions of the connection. In most cases, you just forward the callback to the original delegate (you'll find it in the first element of the delegate array).
However, if the outstanding connection completes (connection:didFailWithError: or connectionDidFinishLoading: is called), you first call the original delegate and then remove the connection from the two arrays. Finally, if the arrays aren't empty, you start the next connection.
Update:
Here's some code. It compiles but hasn't been tested otherwise. Furthermore, the implementation of the NSURLConnectionDelegate protocol is incomplete. If you're expecting more than implemented callbacks, you'll have to add them.
Header File:
#import <Foundation/Foundation.h>
#interface ConnectionQueue : NSObject {
NSMutableArray *requestQueue;
NSMutableArray *delegateQueue;
NSURLConnection *currentConnection;
}
// Singleton instance
+ (ConnectionQueue *)sharedInstance;
// Cleanup and release queue
+ (void)releaseShared;
// Queue a new connection
- (void)queueRequest:(NSURLRequest *)request delegate:(id)delegate;
#end
Implementation:
#import "ConnectionQueue.h"
#implementation ConnectionQueue
static ConnectionQueue *sharedInstance = nil;
+ (ConnectionQueue*)sharedInstance
{
if (sharedInstance == nil)
sharedInstance = [[ConnectionQueue alloc] init];
return sharedInstance;
}
+ (void)releaseShared
{
[sharedInstance release];
sharedInstance = nil;
}
- (id)init
{
if ((self = [super init])) {
requestQueue = [NSMutableArray arrayWithCapacity:8];
delegateQueue = [NSMutableArray arrayWithCapacity:8];
}
return self;
}
- (void)dealloc
{
[requestQueue release];
[delegateQueue release];
[currentConnection cancel];
[currentConnection release];
[super dealloc];
}
- (void)startNextConnection
{
NSURLRequest *request = [requestQueue objectAtIndex:0];
currentConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
}
- (void)queueRequest:(NSURLRequest *)request delegate:(id)delegate
{
[requestQueue addObject:request];
[delegateQueue addObject:delegate];
if ([requestQueue count] == 1)
[self startNextConnection];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
id delegate = [delegateQueue objectAtIndex:0];
[delegate connection: connection didReceiveResponse: response];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
id delegate = [delegateQueue objectAtIndex:0];
[delegate connection: connection didReceiveData: data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
id delegate = [delegateQueue objectAtIndex:0];
[delegate connection: connection didFailWithError:error];
[currentConnection release];
currentConnection = nil;
[requestQueue removeObjectAtIndex:0];
[delegateQueue removeObjectAtIndex:0];
if ([requestQueue count] >= 1)
[self startNextConnection];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
id delegate = [delegateQueue objectAtIndex:0];
[delegate connectionDidFinishLoading: connection];
[currentConnection release];
currentConnection = nil;
[requestQueue removeObjectAtIndex:0];
[delegateQueue removeObjectAtIndex:0];
if ([requestQueue count] >= 1)
[self startNextConnection];
}
#end
To use the connection queue, create an NSURLRequest instance and then call:
[[ConnectionQueue sharedInstance] queueRequest:request delegate:self];
There's no need to create the singleton instance of ConnectionQueue explicitly. It will be created automatically. However, to properly clean up, you should call [ConnectionQueue releaseShared] when the application quits, e.g. from applicationWillTerminate: of your application delegate.
