When Guided Access is enabled, buttons on a UINavigationBar don't activate when you tap on one side of them (and the button does confusingly still dim and highlight as you tap).
You can actually see it in the iOS built-in apps. eg:
iPhone (iOS 9.2.1) > Contacts > triple-click the Home button to start Guided Access
Now pick a contact, then try to go back by tapping near the “s” of “< All Contacts”. You will see “All Contacts” dim and restore as you tap it, but it doesn’t actually activate.
This does not happen when not in Guided Access.
Can anyone else confirm this is a problem?
Why does this happen? Is there a workaround in iOS to avoid this?
I have an app that needs to work properly in Guided Access mode.
UPDATE 15/JUN/2016: The same problem happens in "Single App Mode"
eg Apple Configurator > Set an iPhone or iPad as Supervised > Start Single App Mode > Choose the "Contacts" app and as above see that trying to go BACK using "< All Contacts" doesn't work when you tap near the "s".

No.
In iOS 8, there is no supported method for a third-party app to open Settings to anything other than the top level, or to their app's custom settings, if they exist.
What you see in Tinder and Facebook are system alerts that iOS presents when your app wants to use the network or location services and (cellular data or) wi-fi is turned off. This is managed by iOS, and is not something that Tinder or Facebook had to add to their app.
I have an iOS app that automatically prints a receipt to a thermal receipt printer when an order comes in and works great. However, if the app is in the background, it does not print. Is it possible to allow it to print while running in the background?
There are only a few occasions you are allowed to run certain tasks in the background. See the Apple documentation: https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphoneosprogrammingguide/ManagingYourApplicationsFlow/ManagingYourApplicationsFlow.html#//apple_ref/doc/uid/TP40007072-CH4-SW20
For example: playing audio, fetching the user location, sending notification or certain data from network in the background is allowed. Running your own logic during a background service is, as far as I understood, not allowed (like running it one hour after your app is gone to sleep/background mode).
The only thing that is perhaps an option, is to utilize the time your app has to finish an task after the home button is pressed. There is a timelimit however of 10 or 15 minutes.
I don't know if this is suitable for your situation?
See this stackoverflow question: iOS application executing tasks in background
And this particular piece of code to run the task in the background: https://stackoverflow.com/a/11809211/2740112
Another option is to use Guided Access, which is introduced since iOS6.
With it, you can prevent exiting the app. It's only usefull when using only the app on the device that needs to be used.
Information below from http://www.assistiveware.com/support/faq/page/136:
To turn on Guided Access, do the following:
Go to the Settings app on your device's home screen.
Tap General.
Tap Accessibility.
Under the Learning section (scroll down if necessary), tap Guided Access.
Toggle Guided Access to ON.
Tap Set Passcode and enter a four digit passcode. You will be prompted to enter it again.
(Optional) Toggle Enable Screen Sleep to ON if you want to be able to put your device to sleep with the Power button, otherwise the Power button will be disabled.
To start Guided Access for an app and prevent it from being exited, do the following:
Open the app that you want to lock in.
Quickly press your device's Home button three times to bring up the Guided Access menu.
Tap the Start button in the top right corner of the screen to activate Guided Access. A message stating "Guided Access Started" will briefly appear.
To end Guided Access for an app so it can be exited, do the following:
Quickly press your device's Home button three times to bring up the Guided Access menu.
Enter your four digit passcode when prompted.
Tap the End button in the top left corner of the screen to end Guided Access. A message stating "Guided Access Ended" will briefly appear.

I am developing an iPad application & I want to keep use only my application in iPad. User is not able to make any changes with Home button too.
I have tried same thing with "Guided Access". But, it will stop push notification also.
I have tried it with iPhone configuration Utility. But, I am not able to find any
restriction for Home button.
So, anyone have any idea how can I implement it?
You can't disable the Home button from the sandbox.You have to use the physical accessories to stop the Home button action, after opening your application.
In IOS, when we double tap the home button, it lift's the current app and shows all the app that are running on the bottom. I can scroll the bottom and select the music player option from there. I want to achieve the same screen lift effect, when user taps a button from withing the app instead of double tapping the home button. Is it possible to that? If yes, how can we do it?
No the home button function (unless jailbroken) cannot be re-created inside your UI.
Also since iOS6 users can opt to have Guided Access enabled, if that button where to be created would be considered useless. Now that would be a pain to do in a de-bugging process.
You would have to access the Home Button API (if there was one) as well as the guided access API.
My iOS 4/5/6 app is meant to be used briefly. I want the user to click a "Done, now go away" button which takes them back to the app they were using before mine came to the front.
Is there a way for my iOS to put itself in the background while returning the previous app to the front?
On an iPad, the user can get that effect by doing a four-finger swipe horizontally across the screen. But that gesture is not a complete solution because (a) that gesture does not work on a handheld device, and (2) not many users know of that gesture. I want to programmatically return the previous app to the front.
I want the user to click a "Done, now go away" button
That button is the Home button.
I want to programmatically return the previous app to the front.
There's no public API for switching to another app. Users have a number of options for switching between apps, though. In addition to the swipe gesture you mentioned, they can do a four-finger upward swipe to get to the list of recent apps, or double-tap the home button for the same effect, or hit the home button once to go back to Springboard. Users, not apps, are supposed to be in control of which app is in the foreground. And the way they do that should be standard from one app to another. I can understand wanting to make life easier for the user, but what you're trying to do just isn't possible with the available API.
I Don't think you can do that if the previous application is not your property or if you are not aware if a URL Scheme has been incorporated in the previous application that you know of.
Launch App Via URL Scheme!
