Is it possible and legal  to disable home button and the screenshot feature in an ipad app?

I am being asked to develop an iPad app that can't be closed until some actions are done, also it must prevent the use of screenshot feature and the home button. Is this possible? Is this legal? In case of this not being legal what would happen (in legal terms) if I do develop it?

It's impossible to develop an iPad app that can't be closed until some actions are done.  The iPad programmer cannot override what happens when the user presses the 'Home' button.  The 'Home' button will always tell the front application to go to the background, and if that application doesn't cooperate within a reasonable time it will be terminated.
Bear in mind that an iPad is an overgrown iPhone.  It's always possible that someone will phone you up when you're running an app, and the app must release control and let you answer that phonecall.
I suggest you discuss the design philosophy with whoever wants the application, remembering that computers are meant to help us do what we want to do, not boss us about.

  • HT5457 New app upgrades put 1st gen Ipad users out in the cold - Recently DirecTV and The Blaze both upgraded their ipad apps so that only ios 6 and above were compatible - anyone who has a 1st gen ipad cannot upgrade to ios 6  - what is up with this Appl

    So 1st gen ipad users are basiclly left out in the cold unless they go out an buy a new IPad - of course DTV and The Blaze are blaming Apple and Apple is blaming them - what is the deal Apple -  I pay for my subscription to The Blaze in order to have it on my IPad and now I can't even use it - same with DTV - so is Apple now forcing people to buy upgraded devices thru their apps that will no longer support the older generations - what a joke this is and bad business.

    Unfortunately software always moves faster than hardware.
    Apple's not going to change things. You can try talking to those two app developers and have them make their older versions available.
    Beyond that, if you wish to express yourself directly to Apple, http://www.apple.com/feedback/
    This is just a user to user forum, so there's nothing anyone here can do for you I'm afraid.

  • Is there a way to answer the 5c without swiping? It really is a pain and hard to do at times one handed. Maybe allow favorites to be answered with a click of the home button or possibly all calls with a home button push

Maybe allow favorites to be answered with a click of the home button or possibly all calls with a home button push. First smart phone I have owned and the old flip phone was much easier to answer.....just press one button.

  • My location bar, tool bar (file, edit, tools, bookmarks, help) disappeared and cannot be restored. I have no back button, home button etc. the top of the screen is just an empty blue bar. Internet still works if I click on a hyperlink on the main page.

    My location bar, tool bar (file, edit, tools, bookmarks, help) all disappeared and cannot be restored. I have no back button, home button etc. the top of the screen is just an empty blue bar. Internet still works if I click on a hyperlink on the main page.
    The problem started when I turned on the computer this morning. I tried to install Mozilla 4 from your website and that installed but I still have nothing on the top.

    It may be due to Firebug. Seeing as how you're a web developer, it's very possible you have this installed. The latest version, 1.7X a10, appears to cause everything you described. I downgraded to "a8" and that seems to have fixed everything.
    I also recreated a profile from scratch before trying this out, so I can't guarantee it's definitely Firebug.

  • My sons iPod touch stopped working, it won't charge in a docking station and the computer/itunes won't recognize it when connected.  We have tried holding the power and home button at the same time for several seconds, and the screen still stays black

    My sons iPod touch stopped working, it won't charge in a docking station and the computer/itunes won't recognize it when connected.  We have tried holding the power and home button at the same time for several seconds, and the screen still stays black.  Thanks!

    Hello skdog I possibly think your ipod touch is black because it has not charged. If your dock is broken it might just mean the dock will be broken and so might be the USB port. You should see an Apple shop nearby and hand it over and see what they can do. I hope this information works!

  • Ipad2 won't shut down even when i press the sleep/wake button and the home button at the same time.

    I can't shut down my ipad2 even when i press and hold the sleep/wake button and the home button at the same time.

    If the screen appears to be zoomed in, then does tapping the screen with three fingers zoom you back out ? When zoom is on you should also be able to scroll around the screen using three fingers on the screen.
    If you are seeing the keypad then that should be for the iPad's passcode, I assume that you have one set ? If the iPad is disabled then I wouldn't expect the keypad to show.

  • Permanently Disable Home Button? Help stop the mayhem!

    My home button thinks it's being pushed constantly (closing apps, turning on voice control, bringing up the task bar and search screen, taking screen shots when I press the lock button, etc) but then it works less than half the time I am actually trying to use it. I can't even listen to music because voice control turns itself on. It constanty lights up when in lock position and voice control keeps coming on. It randomly started a few days ago for no reason at all. I want to permanently disable the home button and use assistive touch only (this seems like the most practical way to stop the issue). Please help!!

    In that case, you may want to call the AppleCare number and deal with it that way.  If they can diagnose it over the phone and determine it is a hardware issue, they can arrange shipment of a replacement and the return of your current phone (you will have to give them a credit card which they will release the hold on as soon as the old one is received, since it is technically a warranty exchange).
    Worst case would be they require you to send it in for evaluation, in which case you would have some period without a phone at all.

  • My iPad 2 home button has stopped working I have tried the swivel from landscape to portrait whilst holding the button, I have tried holding the off button then the home button and I was told I could create my own home button in the settings but I can't!

    My iPad 2 home button has stopped working all together, I have tried the swivel from landscape to portrait whilst holding the home button, I've tried pressing the off switch then pressing the home button, the other thing I was advised to do was create a home button in the settings under the accessibility option but I don't have the option I was advised to use under there! Help! It's really frustrating having to turn the device off everytim I want to switch apps and I really can't afford to send it away to be mended! Many thanks in advance

    The accessibilty setting that was mentioned is:
    * Enable AssistiveTouch
    Enable AssistiveTouch which floats a virtual button on-screen which can mimic all hardware buttons on the device:
    Settings>General>Accessibility>AssistiveTouch: turn ON
    *Note* If you power off the device using the AssistiveTouch panel (tap the on-screen AssistiveTouch button, Device>Lock Screen (tap and hold to power off)), you will NOT be able to power on the device *if your Sleep/Wake (power) button is not functioning*. You will need to connect the powered off device either to a PC's USB port or an external charger to power the device back on.

  • My ipod touch is stuck in connect to itunes screen. I've tried to press Power and Home button at the same time for 10 seconds and all it does is go to a black screen. Press power button again and the usb cable with an arrow towards an iTunes logo.

    I have a brand new Ipod touch with front facing camera. Not sure which generation it is. My wife connected the iPod Touch and chose the restore option when connecting to iTunes. It was a mistake and by the time I got there, I saw the screen with USB cable with an arrow facing towards iTunes logo. I cannot get the iPod out of this state.

    Try here:
    iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows
    Also reset the iPod.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.

  • HT201263 When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds.  While in auto-lock it is using battery power and will do so until the battery is drained.  Whats wrong

    When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds.  While in auto-lock it is using battery power and will do so until the battery is drained.  Whats wrong?

    - Try a reset. Nothing is lost:
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears
    - Connect the iPod to your computer and try to restore via iTunes. Try placing in Recovery mode if necessary to restore.
    - If you can't turn the iPod completely off, let the batter fully drain. After charging for at lerast anhour try again
    - If still not successful time for an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • I have an ipod 2 generation, but it wont charger or turn on. i try pressing the power and home button at the same time but it still wouldnt work. what else should i try to do?

    One day I was going to download music from my laptop to my ipod, I was able to download all the songs I wanted but later when I try to charger my ipod it wouldn't let me. The next day I bought a new charger but it still didn't charger. I try pressing the power And home button at the same time but it still wouldn't turn on or charger.

    Try:                                               
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable              
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • How do I get all the control buttons in one place in 3.6.16, like they used to be in previous versions? Having the refresh and stop buttons between address and search windows, and the home button to the far right is awful.

    In 3.6.16, the buttons are all over the place. In previous versions, the forward, back, refresh, stop and home buttons were all together. In this version, the refresh and stop buttons are between the address and search windows, and the home button to the far right.
    I would love to have them all together as they used to be - much more user friendly that way. I have tried installing alternate themes, but the coding of this version over-rides the themes.

    Firefox 4.0 has a combined Reload and Stop and Go button that appears at the right end of the location bar.
    To restore the Firefox 3 appearance you can use these steps:
    * Open the "View > Toolbars > Customize" window to move the Stop and Reload button out of the location bar.
    * Move the Reload and Stop buttons to their previous position at the left side of the location bar.
    * Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.
    * Set the order to "Stop - Reload" or separate them otherwise to get two distinct buttons.
