Hullo,
I would like to establish a voice chat between a user and a taxi driver and I selected GameKit as a solution, yet it seems the two users need to be first friends and that is qyuite a nuisance I think I may somewhat solve.
Yet when I open the voice chat with:
-(void)initializeVoiceChat:(GKMatch*) matchTaxi{
NSError* error=nil;
AVAudioSession* audioSession=[AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
[audioSession setActive:YES error:&error];
if (error){
NSLog(#"AN error occurred while starting audio session: %#", [error localizedDescription]);
}
GKVoiceChat *talkTaxi = [matchTaxi voiceChatWithName:#"redTeam"];
talkTaxi.active=YES;
talkTaxi.playerStateUpdateHandler=^(NSString* playerId, GKVoiceChatPlayerState state){
switch (state) {
case GKVoiceChatPlayerSpeaking:
[self showSpeakingPlayer: playerId];
break;
case GKVoiceChatPlayerSilent:
[self stopShowSpeakingPlayer: playerId];
default:
break;
}
};
[talkTaxi start];
}
The block in playerStateUpdateHandler seems to never be called.

I am using internet availability check using NSURLConnection but it fails to call success or error block:
- (void)isNetworkAvailableWithCallBack:(SuccessCallback)successBlock onFailure:(FailureCallback)failureBlock {
NSURL *URL = [NSURL URLWithString:#"http://www.google.com/"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue new] completionHandler:^(NSURLResponse *response, NSData __unused *data, NSError *error){
if (response != nil){
NSLog(#"Connected");
dispatch_async(dispatch_get_main_queue(), ^{
successBlock(YES);
});
} else {
dispatch_async(dispatch_get_main_queue(), ^{
failureBlock(YES);
});
NSLog(#"Not Connected");
[self presentError:error];
}
}];
}
App works great when app is in foreground or loading first time. Off course my background multitasking is enabled. The issue starts when the following occurs:
Send the app to BG.
Wait some time...
The app get killed by the iOS.
When my app comes again from background to foreground, block gets called with following status code:
Code=-1001
Its a request time out error. but why it is not called whenever my app goes to background(happens not every time, something it works fine).
Is there any thing wrong in my code? And how i handle this.?
You need to enable "Project Background Mode" in Capabilities.
Please refer attached screenshot
I am using the GPUImage framework to record videos. However, while recording, I like to be able to stop recording, start recording, and repeat. My code is as follow:
-(void) startRecording {
NSLog(#"begin recording ");
dispatch_async(recordingQ, ^{
#autoreleasepool {
_assetURL = [self mediaURLAsVideo:YES];
_movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:[self mediaURLAsVideo:YES] size:CGSizeMake(640, 480)];
[_overlay addTarget:_movieWriter];
[_movieWriter startRecording];
}
});
}
-(void) stopRecording {
NSLog(#"stop recording");
dispatch_sync(recordingQ, ^{
[_overlay removeTarget:_movieWriter];
[_movieWriter finishRecording];
});
}
Occasionally, I see this crash:
*** Assertion failure in -[GPUImageMovieWriter createDataFBO], /Users/.../Pods/GPUImage/framework/Source/iOS/GPUImageMovieWriter.m:548
I am not sure why this is the case but any help would be appreciated.
There's a second issue to this as well. Occasionally, the console logs
Couldn't write a frame
Couldn't write a frame
Couldn't write a frame
Couldn't write a frame
Magical Record 2.2:
[MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {
NSArray *cats = [Categorization MR_importFromArray:response.result];
}completion:^(BOOL success, NSError *error) {
//Success is always NO?!
}];
However it does save my records. But they only appear when I restart my app.
I have even tried a loop with MR_importFromObject. Still saves but still no Success is true.
CoreData: error: Serious application error.
Exception was caught during Core Data change processing.
This is usually a bug within an observer of NSManagedObjectContextObjectsDidChangeNotification.
-[__NSCFSet removeObject:]: attempt to remove nil with userInfo (null)
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFSet removeObject:]: attempt to remove nil'
Application crashes on save context operation. (The case is: I perform segue in tableView, enter but even not modifying anything in destinationViewController, and when I'm and delete row in tableView app crashes.
NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext];
[context deleteObject:[self.fetchedResultsController objectAtIndexPath:indexPath]];
// Save the context.
NSError *error = nil;
if (![context save:&error]) {
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
NSLog(#"Unresolved error2 %#", [error localizedDescription]);
abort();
}
Dima,
Chances are you are trying to delete a class with a required parameter. Double check your model or code to meet your entities requirements. If my hypothesis is correct, you just need to make the relationship optional.

I am developing a simple game center multiplayer game. i did manage almost everything except sending messeage to players. what i mean, i can invite player to play game, game is starts etc.
regarding apple documentation i am using following method to send data but it' doesn't work at all.
const char *bytes = "123";
NSData *packet = [NSData dataWithBytes:&bytes length:3];
[myMatch sendDataToAllPlayers: packet withDataMode: GKMatchSendDataUnreliable error:nil];
if possible a working sample would be great.
many thanks.
I did pretty much same.
NSError *errorTransmit;
const char *bytes = "asd";
NSData *packet = [NSData dataWithBytes:&bytes length:3];
[myMatch sendDataToAllPlayers: packet withDataMode: GKMatchSendDataUnreliable error:&errorTransmit];
if (errorTransmit != nil)
NSLog(#"Error sending data to peers: %#", [errorTransmit localizedDescription]);
}
but when code reach
NSLog(#"Error sending data to peers: %#", [errorTransmit localizedDescription]);
I am getting Program received signal: “EXC_BAD_ACCESS”.
that's why i can't see what is going on.
Must confess I've yet to use the GameCenter bits and pieces, but as a general approach I'd have thought you might want to see if there were any errors being generated. As such, if you use something like...
NSError *transmissionError;
[myMatch sendDataToAllPlayers: packet
withDataMode: GKMatchSendDataUnreliable
error: &transmissionError];
if(transmissionError != nil) {
NSLog(#"Transmission error: %#", transmissionError);
}
...you might get a clue what's going wrong.
Incidentally, I'm currently away from a compiler so apologies for any typos in the above. :-)
I cannot see anything wrong here, I am using this code:
NSData *data = nil;
NSError *error = nil;
int packet = 777;
data = [[NSData alloc] initWithBytes:&packet length:sizeof(int)];
[self.mMatch sendDataToAllPlayers:data withDataMode:GKMatchSendDataReliable: &error];
and it works
