How to unlock iOS screen programmatically?

Question

I'm currently exploring creating a jailbreak tweak. I want to unlock the phone screen. How is this done? What private API can be used to achieve this on iOS 7?

Answer 1

If we are talking about jailbreak then you can write a SpringBoard tweak that does this (iOS 7 only)

[[objc_getClass("SBBacklightController") sharedInstance] turnOnScreenFullyWithBacklightSource:0];
[[objc_getClass("SBLockScreenManager") sharedInstance] unlockUIFromSource:0 withOptions:nil];

Without passcode lock the code will turn on the screen and unlock the device. With passcode it will turn on the screen and request passcode.

Answer 2

I use Activator from Cydia to wake and unlock the device via SSH. It works on IOS 10.1.

activator send libactivator.system.homebutton
activator send libactivator.system.homebutton

lock command is here:

activator send libactivator.system.sleepbutton

Good Luck Have Fun :)

My solution comes in two parts but it could be better:

1. Power on screen by simulating a power button press with this code:

   VNCSendHIDEvent(IOHIDEventCreateKeyboardEvent(kCFAllocatorDefault, mach_absolute_time(),
   kHIDPage_Consumer, kHIDUsage_Csmr_Power, 1, 0)); // Power button down
   VNCSendHIDEvent(IOHIDEventCreateKeyboardEvent(kCFAllocatorDefault, mach_absolute_time(),
   kHIDPage_Consumer, kHIDUsage_Csmr_Power, 0, 0)); // Power button up
   

2. After 1, the screen will light up and then you can use SimulateTouch's stouch tool to simulate a swipe from the command line.

For 1 above, your code needs to have the com.apple.private.hid.client.event-dispatch entitlement.

For more, you can also investigate how Activator performs the Unlock screen listener.

Maybe not a direct solution. You can use this tweak and library https://github.com/iolate/SimulateTouch to simulate a user swipe on the lockscreen to unlock the device.
