Popping Sound

I would like to integrate the new Search functionality, but have some questions on if what I'm trying to obtain is possible and if so which approach I should take to implement it.My app has thousands of entries that could be searched and revealed in the app. It's basically a database of the same category of things - none of which is tied to a specific user, these are all static and unique entries that can easily be searched using keywords. It's kind of similar to a database of medial conditions. So I want anyone to be able to search for any of them, even if they don't have the app installed. In trying to figure out how to do this, I have a few questions:Do I use NSUserActivity or the CoreSpotlight API for this? NSUserActivity allows you to specify eligibleForPublicIndexing, but I don't see a description or image property to be able to set - only a title. Also it was mentioned you can't let your activity dealloc, I surely can't hold a reference to thousands of entries. But I don't see any way to make an entry

Dear all, First of all sorry if this post may sound simplistic but it is my first attempt to develop for any apple platform :) Is there a tool that can be used to create nice looking GUI interfaces that can actually then be imported into Xcode to code the backend of the application? I am asking since I am used to using certain .NET GUI components and tools that made this task simple for people like me that are not really that artistic. I am trying to develop a CRUD Frontend for a MySQL inhouse database. Any help or direction to good resources is greatly appreciated.

Hi there, We are planning to issue an app that will enhance our physical book sold in retail stores. It complements the book with audio snippets and drawings/pictures. The app will be free for all on the app-store, and have basic information extracted from the book. People having purchased the book can then unlock the complementary drawings and audio by entering a code which is inside the book itself. For those who didn't purchase the book, they can also unlock the same content via in-app purchase if they want. Please note that we don't plan to put any website link in the app that will allow to buy the book online. We understand this falls under guidelines 11.16, and should be fine with you. Can you please confirm/guide us? Thanks!

I'm building an iOS application using CloudKit.It should allow a user to add, edit and delete Products in the cloud. The user can organize these in Folders.These folders are just other Record Types in cloudkit. There is no limit to the levels of folder the user can use, as any folder can just hold a CKReference to it's parent Folder.All CloudKit communication in my app happens in a dedicated, custom CloudKitController Class.This all works, but stops working after a while for no clear reason.When I test my app, I don't even user folders that are multiple levels deep. However, after testing it a while (creating, editing, deleting products for up to a week), All deleted records seem to reappear on CloudKit. A couple of notes on this:When I reset my CloudKit dashboard and start all over again, it works perfect. No code changes made.Obviously, I'm constantly editing my code as the app is in development. However, I generally don't edit the data types in my code that are to be stored in CloudKit. When I do, this iss

We are developing an application that would benefit greatly from getting two channel audio input - one from the base mic, the other from the front mic (or any other mic). With these two inputs we can do application specific noise cancelling.Is this possible with the new APIs introduced for iOS 9? We have C/Objective-C experience, etc.I looked into this for iOS 7/8 - it does not seem possible. The only noise cancellation I can get is by calling Apple's built in one, which is completely wrong for our purposes.NSArray* inputs = [[AVAudioSession sharedInstance] availableInputs];Will list multiple inputs, but I can't get record from the base mic and another mic at the same time. We are willing to write our own AUAudioUnit if that would help.--T

Here's a simple master playlist to illustrate the question:#EXTM3U #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID=audio_low,LANGUAGE=en,NAME=English,AUTOSELECT=YES,DEFAULT=YES,URI=audio_low.m3u8 #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID=audio_high,LANGUAGE=en,NAME=English,AUTOSELECT=YES,DEFAULT=YES,URI=audio_high.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=100000,CODECS=mp4a.40.2,avc1.4d401e,AUDIO=audio_low video.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=200000,CODECS=mp4a.40.2,avc1.4d401e,AUDIO=audio_high video.m3u8During playback, we can look at AVPlayerItemAccessLogEvent.URI to identify the currently playing EXT-X-STREAM-INF (in this case it will always be video.m3u8). Is there any similar way to identify the currently playing EXT-X-MEDIA?If the audio codecs were different (let's say AAC and AC-3), we might be able to find out by looking at the codec in AVAssetTrack.formatDescriptions. But that's hacky and doesn't work if the codecs are the same like in the example.Ideally, there would be a way to get ei

It works fine in simulator. I can see that it picks up audio.However, when debugging on the device, the blue indicator is stuck to the left and doesn't pickup any audio. iPhone did ask for permission to use Microphone and that was allowed.Did it work for anyone so far?

A part of an application I'm working on uses audio units. In particular, it uses an audio unit with subtype kAudioUnitSubType_AudioFilePlayer. Is it possible to set the playback rate of such an audio unit? If so, how?I thought the parameter kAudioUnitParameterUnit_Rate was what I was looking for, but I've been unable to get that to work.Any help would be appreciated.
