I am trying to show MBProgressHud to MPMoviePlayerController, for that I am observing notifications for load states of MPMoviePlayer, but somehow Method observing notification never observes notifications for load states other then MPMovieLoadStatePlayable. I show MBProgressHud when video starts streaming but it does not work after it plays and then to pause to download video, Due to this I am unable to engage user while video is loading, If anyone has a better method please mention it or if there is any problem in the following code then let me know.
-(void)movieLoadStateDidChange:(NSNotification*)notification{
MPMoviePlayerController *player = [notification object];
if ((player.loadState & MPMovieLoadStatePlayable) == MPMovieLoadStatePlayable) {
NSLog(#"Load state Playable");
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
}else if ((player.loadState & MPMovieLoadStatePlaythroughOK) == MPMovieLoadStatePlaythroughOK){
NSLog(#"Load state Playing");
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
}else if ((player.loadState & MPMovieLoadStateStalled) == MPMovieLoadStateStalled){
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
NSLog(#"Load state stalled");
}else if ((player.loadState & MPMovieLoadStateUnknown) == MPMovieLoadStateUnknown){
NSLog(#"Load State unknown");
}
}
Ok .. i got your problem and the problem is that you are not getting notification for load states except MPMovieLoadStatePlayable. so here what you can do is...like below...
write down below notifiations in viewdidload
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerLoadStateDidChange:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
After defining it in ViewDidLoad , implement those functions like below....
- (void) moviePlayerPlaybackDidFinish:(NSNotification *)notification
{
//your code....
MPMovieFinishReason finishReason = [notification.userInfo[MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
NSError *error = notification.userInfo[XCDMoviePlayerPlaybackDidFinishErrorUserInfoKey];
NSString *reason = #"Unknown";
switch (finishReason)
{
case MPMovieFinishReasonPlaybackEnded:
reason = #"Playback Ended";
break;
case MPMovieFinishReasonPlaybackError:
reason = #"Playback Error";
break;
case MPMovieFinishReasonUserExited:
reason = #"User Exited";
break;
}
NSLog(#"Finish Reason: %#%#", reason, error ? [#"\n" stringByAppendingString:[error description]] : #"");
}
- (void) moviePlayerPlaybackStateDidChange:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = notification.object;
NSString *playbackState = #"Unknown";
switch (moviePlayerController.playbackState)
{
case MPMoviePlaybackStateStopped:
playbackState = #"Stopped";
break;
case MPMoviePlaybackStatePlaying:
playbackState = #"Playing";
break;
case MPMoviePlaybackStatePaused:
playbackState = #"Paused";
break;
case MPMoviePlaybackStateInterrupted:
playbackState = #"Interrupted";
break;
case MPMoviePlaybackStateSeekingForward:
playbackState = #"Seeking Forward";
break;
case MPMoviePlaybackStateSeekingBackward:
playbackState = #"Seeking Backward";
break;
}
NSLog(#"Playback State: %#", playbackState);
}
- (void) moviePlayerLoadStateDidChange:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = notification.object;
NSMutableString *loadState = [NSMutableString new];
MPMovieLoadState state = moviePlayerController.loadState;
if (state & MPMovieLoadStatePlayable)
[loadState appendString:#" | Playable"];
if (state & MPMovieLoadStatePlaythroughOK)
[loadState appendString:#" | Playthrough OK"];
if (state & MPMovieLoadStateStalled)
[loadState appendString:#" | Stalled"];
NSLog(#"Load State: %#", loadState.length > 0 ? [loadState substringFromIndex:3] : #"N/A");
}
let me know it is working or not!!!
Happy Coding!!!!

I'm building a Game Center game in iOS6 and am continuously running into problems with it. The current one has me stumped - Every single time my game tries to authenticate the local player it fails. Every time it is triggering my "disable game center" function and it's driving me crazy.
- (void) disableGameCenter
{
// Write something to disable gamecenter.
// gameCenterAvailable = FALSE;
}
-(void)showAuthenticationDialogWhenReasonable:(UIViewController *)viewController
{
// Pause Tasks Here
// [[[(AppDelegate *)[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:viewController animated:YES completion:nil];
}
- (void) authenticateLocalPlayer
{
localPlayer = [GKLocalPlayer localPlayer];
__weak GKLocalPlayer* weakLocalPlayer = localPlayer;
weakLocalPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error)
{
if (viewController != nil)
{
[self showAuthenticationDialogWhenReasonable: viewController];
}
else if (weakLocalPlayer.isAuthenticated)
{
self.localPlayer = weakLocalPlayer;
}
else
{
[self disableGameCenter];
}
};
}
Forgive me if I'm wrong, but I don't think you are running the authenticate method.
Try this method instead:
- (void) authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[localPlayer authenticateWithCompletionHandler:^(NSError *error) {
if (localPlayer.isAuthenticated)
{
NSLog(#"Authenticated");
}
else
{
NSLog(#"Not Authenticated");
}
}];
}
I'm trying to get ASIReachability to work in my app which works when the connection isn't there but when the connection exists it give the following error:
2013-04-08 12:26:20.501 Your Llanelli Companion[1576:207] -[NSConcreteNotification isReachable]: unrecognized selector sent to instance 0x7d84d30
I can't seem to remedy this and it's beginning to bug me.
.m file:
- (void) CheckIfAInternetConnectionExists
{
Reachability *reach = [[Reachability reachabilityWithHostName:#"http://176.31.101.181:8020/listen.pls"]retain ];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(reachabilityChanged:)
name:kReachabilityChangedNotification
object:nil];
[reach startNotifier];
}
- (void) reachabilityChanged:(Reachability *)reach {
if ([reach isReachable ]) {
NSLog(#"connection");
ServerFound = YES;
[self PrepareStream];
} else{
NSLog(#"no connection");
ServerFound = NO;
[self PrepareStream];
}
}
If someone can figure this out for me I'd be very grateful.
When you receive the notification, the parameter to your reachabilityChanged: method will be the notification itself. To get the Reachability object, you'll need to get it from the notification by sending -[NSNotification object] to the notification.
So something like this should work:
- (void) reachabilityChanged:(NSNotification *)note {
Reachability *reach = [note object];
if ([reach isReachable ]) {
NSLog(#"connection");
ServerFound = YES;
} else{
NSLog(#"no connection");
ServerFound = NO;
}
[self PrepareStream];
}
I am building a AVQeueue Player from a set of encoded videos on an s3 bucket, playing videos in sequence using AVPlayerActionAtItemEndAdvance;
videos are all encoded the same resolution and codec
They are all tested good to play
On some devices this solution below works fine
The issue below is noticed both on IOS 5.x and 6.x
Been trying to check all done in the main thread. (most likely the issue)
Issue: on the simulator and on some devices (noticed on 4s and 5) after an x amount of videos (x being unpredictable at times but usually 3, 4) a video plays only with sound and kills the queue and does not throw "playerItemDidReachEnd" notification. App does not crash or freeze.
No Errors received from "AVPlayerItemStatusFailed" or "AVPlayerItemStatusUnknown"
If anyone has experience with this problem please share.
Code:
-(void)addObservers {
dispatch_async(dispatch_get_main_queue(),
^{
for(int i = 0; i < [self.videodata count]; i++) {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[self.videodata objectAtIndex:i]];
[[self.videodata objectAtIndex:i] addObserver:self forKeyPath:#"status" options:NSKeyValueObservingOptionNew context:nil];
[[self.videodata objectAtIndex:i] addObserver:self forKeyPath:#"playbackBufferEmpty" options:NSKeyValueObservingOptionNew context:nil];
[[self.videodata objectAtIndex:i] addObserver:self forKeyPath:#"playbackLikelyToKeepUp" options:NSKeyValueObservingOptionNew context:nil];
}
});
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *) change context:(void *)context
{
if ([object isKindOfClass:[AVPlayerItem class]])
{
AVPlayerItem *item = (AVPlayerItem *)object;
if ([keyPath isEqualToString:#"status"])
{ //yes->check it...
switch(item.status)
{
case AVPlayerItemStatusFailed:
{
[TestFlight passCheckpoint:#"AV FAILED"];
NSError *error = [item error];
NSLog(#"playback error is %#", error);
break;
}
case AVPlayerItemStatusReadyToPlay:
NSLog(#"player item status is ready to play");
break;
case AVPlayerItemStatusUnknown:
{
[TestFlight passCheckpoint:#"AV STATUS UNKNOWN"];
break;
}
}
}
else if (item == [self.queuePlayer currentItem] && [keyPath isEqualToString:#"playbackBufferEmpty"])
{
if (item.playbackBufferEmpty)
{
[loadingView show:YES];
}
}
else if(item == [self.queuePlayer currentItem] && [keyPath isEqualToString:#"playbackLikelyToKeepUp"])
{
[self.queuePlayer play];
[loadingView hide:YES];
}
}
}

NSLog(#"ended video %i " , (int)self.currentItem);
AVPlayerItem *p = [notification object];
[p seekToTime:kCMTimeZero];
}
How do I know who is calling me?
Identify the number or even the contact in my list case I have.
I can identify if have or not a call, with this code.
void (^ctCallStateMuda)(NSNotification *) = ^(NSNotification * notification) {
NSString *callInfo = [[notification userInfo] objectForKey:#"callState"];
if ([callInfo isEqualToString:CTCallStateIncoming]) {
NSLog(#">>>>>> chegando");
} else if ([callInfo isEqualToString:CTCallStateConnected]) {
NSLog(#">>> atendendo <<<");
} else if ([callInfo isEqualToString:CTCallStateDisconnected]) {
NSLog(#"desconectado >>>>>>");
} else if ([callInfo isEqualToString:CTCallStateConnected]) {
NSLog(#"discando");
} else {
NSLog(#"nada");
}
};
CTCallCenter *callCenter;
callCenter = [[CTCallCenter alloc] init];
callCenter.callEventHandler = ^(CTCall* aCallIncomming) {
NSDictionary *dict = [NSDictionary dictionaryWithObject:aCallIncomming.callState
forKey:#"callState"];
[[NSNotificationCenter defaultCenter] postNotificationName:#"CTCallStateDidChange"
object:self
userInfo:dict];
};
[[NSNotificationCenter defaultCenter] addObserverForName:#"CTCallStateDidChange"
object:nil
queue:nil
usingBlock:ctCallStateMuda];
You don't have access to this information in the public SDK (a jailbroken iPhone is another matter). Apple prohibit apps from having access to any information relating to call history. The code you've posted above is so your app can detect when the user is receiving a phone call and adapt their interface accordingly, but that's it.
Long time reader, first time asker.
I'm programming an iPhone application that needs to handle the phone going in and out of data coverage with some elegance. I can set up the Reachability with notifications to find out when it gets lost or comes back, but it would be helpful for me to know how often the radios are looking for a signal - and does this rate slow down over time? Also, is there anything I can do programmatically (like pinging a server when I know I don't have coverage) to speed it up?
Battery life is not really a big concern for me, and I will not be deploying through iTunes.
What you want is possible. First off get Reachability code from Apple. Then you need to write a checkNetworkStatus implementation. This is where notifications come -
#import "Reachability.h"
- (void)checkNetworkStatus:(NSNotification *)notice
{
// called after network status changes
NetworkStatus internetStatus = [internetReachable currentReachabilityStatus];
switch(internetStatus)
{
case NotReachable:
{
self.internetActive = NO;
break;
}
case ReachableViaWiFi:
{
self.internetActive = YES;
break;
}
case ReachableViaWWAN:
{
self.internetActive = YES;
break;
}
}
NetworkStatus hostStatus = [hostReachable currentReachabilityStatus];
switch (hostStatus)
{
case NotReachable:
{
self.hostActive = NO;
break;
}
case ReachableViaWiFi:
{
self.hostActive = YES;
break;
}
case ReachableViaWWAN:
{
self.hostActive = YES;
break;
}
}
return;
}
Now you need to start your notifications -
-(void)viewWillAppear:(BOOL)animated
{
//NSLog(#"View Will Appeared!!");
// check for internet connection
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(checkNetworkStatus:)
name:kReachabilityChangedNotification
object:nil];
internetReachable = [[Reachability reachabilityForInternetConnection] retain];
[internetReachable startNotifier];
// check if a pathway to a random host exists
hostReachable = [[Reachability reachabilityWithHostName: #"www.google.com"] retain];
[hostReachable startNotifier];
// now patiently wait for the notification
return;
}
