  iphone memory-management release nszombieenabled
  With NSZombieEnabled turned on it will provide some guard against the EXC_BAD_ACCESS issues happening at runtime. I am doing dual-diligence to make sure no/little memory leaks, but I might over releasing so having NSZombieEnabled turned on would help prevent that, am I right? Or with NSZombieEnabled turned on, would all memory releasing operations be translated into no-op? It’ll be a big problem is that’s the case.

  ios exc-bad-access nszombie nszombieenabled
  We have a EXC_BAD_ACCESS crash in our iOS application but it happens only when certain external accessory is connected. Unfortunately this accessory doesn’t allow debugging (no pass-through connection). Is it possible to permanently enable NSZombieEnabled for the application so it’s active even when the application is started directly on the device?

  Removed release statements. Some of them seemed to be okay, but that was probably just because other things were exploding first.- (void)handleNowPlayingItemChanged:(id)notification {MPMediaItem *item = self.musicPlayer.nowPlayingItem;NSString *title = [item valueForProperty:MPMediaItemPropertyTitle];NSNumber *duration = [itemvalueForProperty:MPMediaItemPropertyPlaybackDuration];float totalTime = [duration floatValue];progressSlider.maximumValue = totalTime;CGSize artworkImageViewSize = self.alb

  ios nszombieenabled
  When I run with a connected iPad, I can enable NSZombieEnabled via “Enable Zombie Objects” or by passing NSZombieEnabled as an Environment Variable. However, I cannot seem to produce builds (i.e., the kind you archive and distribute ad-hoc) with NSZombie enabled.How can I enable NSZombieEnabled for archive release builds?The code I am using to determine if it’s enabled from within the code is: (getenv(“NSZombieEnabled”) || getenv(“NSAutoreleaseFreedObjectCheckEnabled”))

  ipad crash nszombieenabled
  When I push a certain view controller, then go pop it and then repeat a seemingly random number of times the app eventually crashes with the error EXC_BAD_ACCESS.This I can reliably replicate EVERY TIME. It happens mostly the second time I pop the view controller, but sometimes it can be the third or fourth.So I decided to set NSZombieEnabled to see what the problem was.But with this enabled the crash can’t be replicated. All thats changed is I check the box next to “NSZombieEnabled” in my activ

  ios core-data nszombieenabled
  So, I have this problem, my app plays audio, and it stored the playback position whenever paused is triggered, either by tapping a button, or selecting other track. When the latter happen, I programatically call pause: and set 0.5 sec delay before start playing the next track, this is where the problem occurs.The code is dead simple.NSInteger x = [_player currentPlaybackTime]; if (x && x > 0) {[_nowPlaying setValue:[NSNumber numberWithInt:x] forKey:@”pausedAt”];NSError *ctxErr;if (![_
