Is there any way to detect the shake when the application is in back ground in iOS ? Actually in my application i need access my application when the device is in lock screen to call some web services. Is there any way to do this to aces my application while the device is in lock screen in iOS?
Simple answer NO there is no way of detecting shake in background mode sorry.
Unfortunately this isn't possible in iOS 7 are lower.

I want to use an old iPad to view an ip camera feed. Instead of keeping the iPad on all day, I want to be able to tell the iPad to wake and open the camera viewer application when the camera senses motion. (Not just a small notification on lock screen, I want to be able to view a full screen image of the cameras feed). After a given period of time the iPad would go back to an off/sleep mode. Is this even possible in iOS? Thanks!
Take a look at the "Singe App Mode" and "Background Execution". Choose an event type that can take your device out from background mode, like VOIP. Do not expect the app to be accepted in the public app store.
I'm building an ios app with an alarm feature. I would like to show a view when phone is locked. I want to look exactly like on iOS alarm. If you're an iPhone user try to alarm and locked your phone you will get what i'm talking about. Is it possible? If possible how?
Thanks in advance.
iOS doesn't provide apps that kind of access to the lock screen (or any screen not in your app), so it's impossible to make it exactly like the iOS native alarm. The closest you can get is sending notifications to simulate an alarm, which are visible on the lock screen
I want to get remote access of my iOS app running on one iPad in another iPad. Is there a way in iOS SDK to achieve this?
Any help would be highly appreciated. Thanks
No, there's not. You can mirror the screen to another device using AirPlay, but there is no way to "drive" the device remotely. (There's an app called "Reflector" that lets you mirror you iOS device onto your Mac, but it's view only.)
I'm working on a proof of concept app. I'm using Xamarin for iOS. The iPhone app runs in the background and watches for particular BTLE devices and speaks using TTS when the signal is at a certain strength. I have TTS working and I can recognize the BTLE devices when the app is in the foreground.
However, I'm having trouble getting either working when the iPhone screen is off. In Android, I'd just use a wake lock, but that appears to not be available in iOS. I tried setting the background modes in the info.plist file for BTLE and sound, but I don't see any processing happen while the unit is suspended. Can anyone point me in the right direction?
This is just a proof of concept, so I'm only looking at the latest iOS version and I'm interested in even hacky answers.
Thanks!
You will need to create at least one background task UIApplication.SharedApplication.BeginBackgroundTask and end it with EndBackgroundTask when you finish transferring your data.
Note that you will have approximately 10 minutes in background. If user switch back to the app the time will be reset.
You might also want to disable application idle timer to prevent the screen to go black when the user doesnt touch it.
I've developed Android app which has a background service in the sleep mode. This service works with accelerometer data and can launch the app from the sleep mode over the lock screen.
Is it possible to make the same on iOS?
I mean:
Create a service which can work in background with accelerometer data.
Service can launch the app when the phone is in the sleep mode over lock screen. (without unlocking)
If I'm not mistaken it must be possible on iOS7, isn't it?
Thanks!
Yes – Apple publicly stated background processing at WWDC keynote and it can be done to a degree on iOS6
No – Apple will 'probably' never allow an app to be opened without the user instigating it and certainly not over the lock screen.
You could use Push / Local Notifications which do appear on the lock screen to try and entice a user at a specific time to launch the app but no guarantees.
