Play alert sound (same as default message ringtone)
Hello all,
Quick question -
Is it possible to use one of the default sounds included on the iPhone - Marimba etc. in an iPhone application?
Thanks,
Teja
The actual directories will only be accessible after JailBreak.
Ringtones (including Marimba):
/Library/Ringtones/
System sounds:
/System/Library/Audio/UISounds/
Or use 'AudioServicesPlaySystemSound()' like mentioned by Black Frog.
Note: This method is undocumented and will cause AppStore rejection.
Download link for system sounds (comment by clusterfu_k):
Can I get default audio files of Iphone (marimba, alarm, ascending,...)?
Note: Possible copyright infringement.

What to do when my app receives memory warning?
I developed an iPad App where I must display a lot of media (photos, videos, pdfs). My app uses the TabBar Application model. I found all of my memory leaks and now I am leaks-free but my App still crashes. I don't put any images in the cache with imageWithContentsOfFile, I release everything, the movieplayer, UIImage, UIWebView. However, I still receive memory warnings. So what can I do with these warnings ?
You need to keep your images in memory in such a way that you can go back and purge them when the device asks for memory. And then you need a way of knowing what you've purged so you can reload it when you need it again.

iPhone Data Usage Tracking/Monitoring
I'm trying to build a "Data Usage Monitoring" iphone app as a quick demo, but haven't been able to figure out how to get CellularData/Wifi usage statistics programmatically.
I know this is possible, as there are several apps in the app store for this (DataUsage, DataMan).
I know for a fact that these are not scrapping the cellular provider's pages to get the data usage, so I'm wondering how they are able to achieve this.
Couldn't find anything in the iOS 4.2 SDK Documentation.
I'm guessing they are somehow getting the data that is displayed under "Settings -> General -> Usage",
Hey, this is sort of untested - I tried it on the simulator, but it obviously doesn't store any data usage statistics. Try to give this code a shot on an iPhone device.
NSLog(#"Contents of the user defaults: %#", [[NSUserDefaults standardUserDefaults] dictionaryRepresentation]);
It should print out the entire contents of the users preferences. You should then be able to dig out the appropriate keys for accessing the data you need.
Tell me whether it works or not :D

Is it possible to get GPS satellite numbers via iPhone SDK ?
I am looking for the equivalent of LocationManager.getGpsStatus(...) on Android (link). More precisely it would be interesting to get, for all tracked satellites: their PRN numbers, C/N0, azimuths and elevations.
I know the SDK does not have any such interface, but does anyone know of a possible way to access to these values, or any software project showing such information?
There is no public available API that allows you to get this kind of detailed information about the GPS satellites.

How to share custom data between iPhone applications?
Aside from using URL scheme, what other means are there for two iPhone apps to pass data between each other (ideally, without launching another app -- which is one of the downsides using URL scheme)
Unfortunately apps are sandboxed, and can't communicate with each other. You would have to implement something server-side to act as a central location for this data.
