I live in Canada, so am fortunate that I can tether. One issue is that to toggle tethering, you need to drill down four screens in Settings, which is just a big hassle.
A Google search returned nothing, so I was wondering if anyone here knew the code to turn on/off tethering?
I know there's a toggle for SBSettings, but I do not have a jailbroken phone, I just want to create an app I build onto my phone and have an icon for quickly toggling it.
Thanks
You cannot alter phone settings from within an application using any APIs allowed by the iPhone SDK. As you point out - there is an SBSettings toggle - which relies on a Private API (which you agree not to use when you get the iPhone SDK from Apple, incidentally).
There is a file located in the Preferences folder, along with the com.apple.SpringBoard.plist:
/var/mobile/Library/Preferences/com.apple.MobileInternetSharing.plist
In that file, you will want to set 1023 for key State to enable the Tethering feature. To disable the feature, you will want to set 1022 for key State.
This action is only possible on a jailbroken device

Until now asper my knowledge it was not possible to restrict the app from exiting. User could press the home button and app will exit. Then came multitasking and when we press home button app would go in background, but on long press user can still close the app.
I am working on developing anti-theft kind of application and needed to lock the phone programatically, but seems that it is not possible.
Also another problem was if user exits app then there is no way it will get notifications from the web. After some research I found the we can restrict the application from being exited using GUIDED ACCESS facility provided by iPhone6.
But all the links that I found states the procedure to do it from settings menu of iPhone.
I wanted to know if there is any way to do it programmatically or at least display relevent iphone settings screen directly.
It is not possible to restrict your app from exiting or allowing it to lock the iPhone programatically.
This is FAR beyond the scope and bounds of security for your app to infect the system this way.
As for Guided Access it is a feature provided in iOS6 allowing parents to use their device with their kids and prevent accidental app exits or unintentional taps outside a certain bounds. It also has availability in a kiosk mode for small businesses using iPads as public information access points that want the iPad locked to an app or webpage. It is not a public API allowing your app to turn such blocks on. This again is for the security of the device.
In many applications, such as the Mail app, if the device is in airplane mode a notification will pop up that says "Turn Off Airplane Mode or Use Wi-Fi to Access Data."
I thought that this would automatically be invoked if my app tries to access the internet, but it is not. Is there a special method to do this, or if not how can I check if the device is in airplane mode and provide a link to Settings to disable it?
If you add the UIRequiresPersistentWifi key to your Info.plist and set it to YES, then if you're in Airplane mode, you'll get the standard "Turn Off Airplane Mode..." popup on launch.
I test in my app. I find it changed. "UIRequiresPersistentWifi" => "Application uses Wi-Fi".
I hope it will help somebody.
You could use the apple's reachablity framework when you app launches to check for network connectivity. Check this out
http://developer.apple.com/library/ios/#samplecode/Reachability/Introduction/Intro.html
I have a wrapper class for reachbiltiy APIs to make it simpler to use. (ASIHTTPRequest has one as well).
https://github.com/daltoniam/GPHTTPRequest
see the GPReachablity class for checking for connectivity. As far as a dialog prompt, not sure there is a way to push to the settings app. Any questions let me know.
If you want the standard Turn Off Airplane Mode or Use Wi-Fi to Access Data [settings | ok]
Add a new property in your info.plist by clicking the + sign at the top.
The new property is called UIRequiresPersistentWiFi (this is similar to postings above, but needs to be exact otherwise it doesn't register)
Change type from String to Boolean
Change value from NO to YES
Clean and rebuild your app
Take a look at this. Apparently, Airport control was moved by Apple into a separate framework
It seems there is no standard way to notify the user to turn airplane mode back on. As you mentioned, this obviously isn't very elegant, so I assume apple deleted this feature.
I am developing an iPhone app, that will not be distributed on AppStores. I have tried to search for private api but no luck. When the user tries to quit the app, I want to prompt the user to enter the correct password so as to enable him to exit the app. How can I achieve this? Thanks in advance.
Cheers!!
It sounds like you need something similar to iOS "Kiosk Mode" as described in this answer:
Put an iPhone or iPad into 'Store Demo' mode
Using that description in conjunction with the following steps might achieve precisely what you want:
Have a "Quit" button
Show a password dialogue when it is pressed
If it was correct, read an out of bounds array location (or do whatever) to crash the app
With that config installed you'd get stuck in whatever app you launch next, though.
You can't! You'll have to password protect the launch instead.
If you want to prevent the user from quitting your app, you'll need to physically cover the home button. This isn't a bad solution if your goal is to do something like a kiosk or a point of sale system, where you probably want to mount an iPad in a secure enclosure to prevent tampering or theft anyway. There are quite a few such enclosures on the market in a variety of styles.
For a normal app, though, there's really no solution -- iOS isn't designed for whatever you're trying to do.
The only way I could think to do what you want (which is to prevent access to certain apps) would be to replace the SpringBoard application (this is the method used by Apple itself in the App store models of the iPhone and iPad that restrict the things you can do on the devices). #owenfi pointed at one way to do that without jailbreaking, but in general it is limited: you won't be able to "exit" the app, you will basically just be able to run a single app.
I have been looking around for an answer to this, but haven't been able to find anything. Can I toggle on/off my iPhone's bluetooth signal from an app. I hate the process of doing it through the settings app.
I don't have any desire to get this approved through the app store, I just want it for use on my phone (very similar to the Android functionality).
Yes! Jeff Broderick made a handy site that lets you add a shortcut icon to your home screen to do this sort of thing. http://brdrck.me/settings/
I use it for Airplane Mode and Wifi. Haven't tried the Bluetooth, but I'd imagine it works as well as the others.
Is it possible to create an app for the mac (and iphone afterwards) that does something when it detects that the focus is on a certain object in the screen?
Meaning, the program runs in the background, and when it detects that the focus (or cursor) is on an edit box, it will run something.
Hopefully I made myself clear!
Thanks!
You can do this on the mac by using the Accessibility Framework.
Note that users will have to manually enable assistive devices and you will not be able to distribute your app on the Mac App Store due to Apple's soon-to-be-implemented sandboxing restriction.
On iOS, you can detect focus to certain but not all elements using specialized delegate methods such as textViewDidBeginEditing:. That said, as users use taps to navigate iOS apps most of the time, simple tap handling seems like a much better approach.
On the iPhone, you can only detect focus within your own app, there's no way to observe other apps from the background.
On the Mac, as 0x90 noted, the closest you'll get are the Accessibility APIs. The UIElementInspector sample code may help you to get started.
