I know that it is not possible to access the ringtones in iOS, but is it possible for the user to import a ringtone into my app for usage? I have read about iTunes file sharing, but I wouldn't want to do that. Is it possible to have the user manually search for their ringtone/audio file on their device and select it (like if I made a file explorer) and add it into my app? Another alternative, could I have it in one of my servers, like say the user uploads it to my server and then the app can have access to it to download and save it to the phone? I am running out of ideas lol. If this is not possible it just looks like I will be scraping this idea and making it an Android only app. I was hoping to make it for both iOS and Android. If it's not possible, what can I do. Any word from the wise?
There is an option as AudioServicesPlaySystemSound in AudioToolbox. Check the documentation here. I am not sure this can be used to access the ringtones. This should lead you to right direction.
This function plays a short sound (30 seconds or less in duration).
Because sound might play for several seconds, this function is
executed asynchronously. To know when a sound has finished playing,
call the AudioServicesAddSystemSoundCompletion function to register a
callback function.
Not sure whether the usage of this is allowed by Apple, but it looks like it can be used.

I am not a coder and having a web platform built with PHP that includes a series of 1-1 video chats in a scheduled networking "event". The problem that the developer is not able to solve with the video plug in that they are using (https://www.magnoliyan.com/video-chat-pro/) is that the user needs to give camera permisson before each chat. I need this permisson to happen one time only at the beginning of the event and not need there to be any further permission giving throughout the event. Of course I would like this to work on all platforms. I'm exploring agora.io as an option to solve this and replace the current plug in with agora. Does anyone know if agora would be the right fit for this or which video chat platform I should use to accomplish this? And if there is specific developer kind of language or code - please speak in as if I was a developer and I will pass on what you say to him directly. You don't need to worry about whether I will understand it.
Thanks!

Agora.io like any other WebRTC provider requests device camera permission only once. And all subsequent Videocall won't need any special permission (provided that they are on the same domain)
More specifically, Agora.io requests browser permission when stream.init method is invoked. This also turns on the camera light. stream.close turns off the camera light and deallocates the resources.
However, the subsequent stream.init function calls do not require permissions. (Camera light will just turn on)

I want to make an application which will send information to a server about user's location every 30min. It is needed to provide location specific push notifications.
I need such functionality for Android/iOS, which would work in background (also if device is restarted). I found some articles covering background services and I created background service doing that, but after phone is restarted it won't work.
Is it possible with Android and iOS? How can I achieve that?
With iOS, no. With Android, yes.
Apple has gone to great lengths to limit what apps can do. You can do some things in the background for an extended period of time (GPS, play audio, Voip, etc), but after a reboot your app will not be restarted until the user opens it again. There are exceptions to this. Voip apps are allowed to restart after a reboot, but apple will not approve your app for the App Store unless you actually have a place for a user in your app to use the Voip feature. Geofences are a possibility, but I haven't had experience with that feature yet. In my experience, Apple does whatever they can to make sure your app doesn't run forever.
With android, there is more flexibility and what you propose is totally possible. I've listed some important links below, since most of those solutions are far better documented than what I can do here.
Essentially you need to register as a boot receiver and then send an intent to start a titanium android service when the boot event is received. I don't have experience with starting a titanium service, but I'm sure its a simple intent you need to fire. Either way you'll need a module for this native code. I attached a link to a bencoding titanium module that may help you, although there may be some others out there. You may even need to code one yourself.
Samsung is notorious for stopping your app with their SPCM feature. You may want to familiarize yourself with it. I've added a stackoverflow discussion link below.
I don't know all of your system requirements but honestly, for any app I would try my best to not run forever. It will hurt the battery life for your users and will add a lot of complexity. Maybe you could simply have the app check the GPS coordinates when it receives a push notification and decide right there and then whether to present a notification to the user? Just something to consider.
Either way good luck!

Dealing with Samsung SPCM killer
I'm playing around to make an app that lets people stream cartoons that I make. It's a very simple app, one ImageView is just loading in a html-homepage in a UIWebView. Witch contain links to .mov files. So if you tap them a movie will start playing. This is because I just want to update the html-file with new cartoons every week.
Is this an "ok" way to do things code:ing-wise? Or am i obligated to us some Objective-c streaming functions?
Is there a specific file-type that i have to use in the movie-files on the server?
Is the HTML static in your app, or does it point to a server? If it's the former, you may be able to get the app approved doing it the way you suggested, depending on the reviewer. If it's the latter, you're unlikely to get it approved by apple.
They tend to frown upon web sites bundled into apps, and will tell you to simply make your website usable with the phone. See section 2.12.
My suggestion is to spend a bit more time and offer iOS users a better - and more immersive - experience than is available via the web. As I'm sure you've found, there are many built-in ways to stream movies and to present them in a manner that surpasses a web-page-like experience.
I need my application to perform a background task every day, but it does not comply with Apple's specification for running in background.
It's none of these: audio, location, VOIP, news stand, external-accessory—, Bluetooth-central.
I'm planning to use local notifications, but the point is, that if the user doesn't open the app (and just leaves it in the background), I cannot plan new local notifications.
What should I do in this situation?
Make something else.
Seriously, if your app doesn’t at least technically fit one of those categories, you’re not going to be able to get it to do background work in a way that’ll get you approved for the App Store.
I’ve seen apps that added specific functionality in one of those categories, orthogonal to their actual purpose, to be allowed to run in the background; for instance, there’s a couple of weather apps out there that play a continuous audio file—one of the available sounds being a silent one—in order to be able to update the lock screen’s “now playing” image with live data. If you don’t mind your users being unable to listen to any other music, and have your app continuously active (which might cause additional battery drain), that could work. But if you’re trying to have your app invisibly do things in the background, without interfering with anything else, in a way that’ll get you into the App Store, you’re probably out of luck.
Four options:
Go for jailbreak
Try to get in the app store as one of those types of apps, making up a feature that uses one of those types.
(my favorite) Really rethink your system, is it really necessary to schedule background tasks? Can't the user wait a bit when he opens the app? That loading can be performed in background. And can't you offload some of the work to a webserver? Are you collecting data? You shoudln't without the user consent.
Let your user know that it's important for him (he's the one using it right?) that he opens the app once a day.
I think I covered all yohr options except the one already covered by Noah.
I want to make my iPhone app display on a Mac's screen, kind of like AirPlay does with other machines. The only way I have heard to do this is, although I do not like it, turn the iPhone into a server. Unfortunately, I cannot figure out how to do so. I also wanted to set it up in such a way that my Mac automatically detects it. I have seen a similar setup in the game Chopper 2. My Mac app will have a simple timer that fires every few seconds to look for the iPhone, in the same way that Chopper 2's "Find iPhone" button does.
Is there a simple way to turn the iPhone into a server, or start a "session" like Game Center does?
One last thing: I know it is somehow possible, because another app I have actually gives my iPhone a web address at the click of a button. It is called the Dicenomicon, if you want proof.
First there is no easy way to redirect your display to Mac, even if you made it a server of some kind.
Second, to discover or publish customized services on WLAN, you may want to refer to the samples on Bonjour:
CocoaHTTPServer: a simple TCP/HTTP server.
WiTap: an app that discovers and connects to services of the same kind on WLAN by Bonjour.
I'm not really sure what you mean by "server", because there is no way to share the screen of an iPhone using the official SDK, although this is possible by jailbreaking.
It would be possible, however, to send data back and forth between the Mac and iPhone, and display the data on the iPhone, on a Mac. Using that data, you could try to recreate the interface on the Mac. All of this could be accomplished using sockets. A class that might help with that would be cocoaAsyncSocket, which makes network programming a lot easier.
The auto-discovery of iPhones on the local network is achievable with Bonjour. Without getting into too many details, NSNetService would allow you to publish a service for your app from an iPhone, and NSNetServiceBrowser would allow you to find that service on the local network from the Mac. From the NSNetServiceBrowser, you could establish a socket connection with the iPhone.
Good luck!
You might want to take a look at the GameKit APIs, I know they do something similar between two iOS devices.
