Popping Sound

Basically, what i need here is that, after my app has recorded an audio, I have written code that alters its pitch and/or rate, And I use Activity View Controller, to share the audio from the app to other medias. But, what happens, when I share it is that, the ORIGINAL RECORDED audio is shared, instead of the audio that had EFFECTS to it like rate or pitch. So, I do i go about sharing (itd be awesome, if you could also tell me how to save then share) the audio.EXAMPLE OF MY CODE://For fast rate playback@IBAction func fasterAudio(sender: UIButton) { audioEngine.reset() audioPlayer.currentTime = 0 audioPlayer.rate = 1.75 audioPlayer.play() }//For higher Pitch @IBAction func highPitchAudio(sender: UIButton) { audioPlayer.stop() audioEngine.stop() audioEngine.reset() audioPlayer.currentTime = 0 var audioPlayerNode = AVAudioPlayerNode() audioEngine.attachNode(audioPlayerNode) var changePitchEffect = AVAudioUnitTimePitch() changePitchEffect.pitch = 1000 audioEngine.attachNode(cha

I am developing an app for a client who wants to use a non-autorenewing yearly subscription revenue model. Basically, the user would have very limited features in the app, unless they purchased a yearly subscription. I cannot talk about the details of the app, other than to say it has been designed to use tab navigation. 4 tabs: one tab with a list-based screen populated from data form a backend server; another tab with a Map showing annotations (related to the list items from the first tab); another tab that contains some different data from a backend server; and, lastly, a tab that contains resources (basically publicly-accessible information) related to the theme of the app.The client wants to only make the Map tab accessible, with very limited content and interactivity, for free. Selecting any other tab or trying to drill down from a limited number of map items to more detail would require that the user purchase a subscription. I have tried to stress to the client that this is a poor user experience, and

We use ABNewPersonViewController to create contact in our app.If user turn off privacy and open our app , tring to create new contact again.The ABNewPersonViewController was pop up and says This app does not have access to your contacts.Wired thing happen next , it still show the textfields for user to create.Seems the app's alert didn't show at the top hierarchy.

Greetings! (I am hoping this is the right place to ask this/marked as a question)I have recently tried stack overflow for this problem, but I haven't been seeing any success.I hope for more luck here!As the title suggests, I wish to limit the number of AdMob insterstitial ads in my Swift iOS app. Basically, I have an app that is a bunch of text and buttons, so I'm using button actions to control interstitial placements.Here is my interstitial ad criteria:Have an interstitial ad show after 3 button clicks on a pageIf an interstitial ad shows up, no interstials may show for the entire app until 3 minutes are up.I've done as much research as I can, but I'm still at a loss on how I can achieve these results. I'm not much of a programmer, but I am trying my best!Here is my current swift code, my apologies for the visual formatting, I tried to make it as eye-pleasing as possible.The swift code below simply makes interstitials pop up at every button click (along with banner ads loaded in):__________________

I'm trying to implement a fade-in effect based on AVPlayer + AVAudioMix + AVAudioMixInputParameters. It basically works except when playing the audio for the first time after starting my app there is a click in the beginning. Subsequent plays work perfect though, but the first-time glitch is pretty stable and reproducible.My Play button is enabled only after the AVPlayerItem's `status` is set to ready, so it's impossible to fire a play method while the player is not ready. In fact it doesn't matter how long I wait after loading the audio file and constructing all the objects.This happens on OS X (10.10), I haven't tested it on iOS yet.Note that for this test you need an audio file that starts with sound and not silence. Here is my stripped down code without the GUI part (`testFadeIn` is the entry point):static AVPlayer* player; static void* PlayerItemStatusObserverContext = &PlayerItemStatusObserverContext; - (void)testFadeIn { AVURLAsset* asset = [AVURLAsset.alloc init
