I know that this might be useless, but I just wanted to ask.
I have an iPhone 4s running iOS 5.1.1, a few months ago my wife did set a restrictions passcode on it to prevent our daughter from changing some settings accidentally while she's playing games with the phone.
Now my wife forgot that code and needs to change some settings herself and of course she's not able to do so.
I've got a way around this but it's necessary to access /library/keychains to do it.
Since the phone is not jailbroken, I can't access that path (Using i-Funbox)
Is there any other way that I can use it to access this path ?
Is there any way around to reset this passcode ?
Without jailbreak, you can't. However, you can easily jailbreak the phone using Absinthe 2.0.4.
if you don't want to do that at all, you can make a backup of the device using iTunes, then restore its firmware to factory defaults, then the pass code will be gone. You'll get back all your data after re-syncing with iTunes.

Okay, I have asked Reddit 3x and Apple once and no one could answer this so I am coming to you guys. Please be the ones to answer this validly. Okay, details. Yubo remembers my phone after reinstall and I do not know how. I have tried the following:
Changed my IP Address using a VPN
Change my IDFA through reset identifier which I now know is pointless as since I had “limit ad tracking” on the output would have been an output value of numerous 0’s (though this some how got me unbanned from the “Instagram” app, idk how tho)
Changed my IDFV by...well reinstalling the app (Yubo is there only app so don’t ask about other apps from the vendor)
Change my iPhones name multiple times
Prevented the app from being backed up on Icloud then reinstalling
I also logged out of the Icloud prior to using the app for the first time after reinstall
And that’s about it. I am aware the app may recognize: my phone, ios version and hardware. However, none of that is exclusive to my phone. I have read people having the exact same model and phone so i doubt Yubo is remembering me through that. I have never met an app so smart before, but I know some of you have probably been screaming this entire time one thing I have missed so please tell me what i missed and a way to change it without resetting my phone.
My device: Iphone6s and IOS 11
I am developing an iPhone Application to wipe all data from iPhone including photos, videos, contacts, messages, apps, etc. programmatically. I wish to achieve this with an iPhone Application only.
The approach I am thinking of somehow I manage to Clear data from iPhone and rewrite the memory with some junk files or binary data 1010 say. (Its just an idea!)
All I have managed to do is delete photos from Photos which are further not deleted from Recently deleted folder in Photos App.
Also, I found this Programmatically How to wipe out iPhone or iPad data in i phone apps in i phone apps which declines it's feasibilty.
But, Is there a way to programatically restore my iphone to factory settings? says using the C files mentioned here https://github.com/lite/osxrce/blob/master/resetapp/main.m can may be make it possible. They say they tried it on a jailbroken device though.
What you are hoping to do isn't possible on an non-jailbroken iPhone. You will be violating the iOS sandboxing among other things.
A similar outcome may be possible by creating your own MDM server, and building your app to interface with it. On first installation of your app, you can have it install the MDM profile. The app can then feature your 'Wipe' button which can signal to the MDM to send a wipe push notification to the device.
It would take a lot more work that what you're asking about, but it should be possible.
Reference: https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf
Apple do not allow to delete files which aren't created or part of your application, so you will not be able to delete data of other apps.
I don't think you're allowed to do that anyway. Even if you were able to do it, it would not be accepted on the app store.
You can backup the iPhone via AppleMobileBackup.exe -b, then modify the according
database file(such as addresscontacts, messages), and restore the modified ituensbackup files to the iPhone via AppleMobileBackup.exe -r.
This is a strange one, I have a need to create an iOS app that runs in the background on an iOS device, but can not be visible on the Home screen of the device. The app may need to show up in Settings to configure a few options, but it mostly needs to run behind the scenes.
I do not need to publish this app on the app store, it is strictly an enterprise app for my company.
Does anyone know how this kind of behavior might be achieved? Configuration profiles? API's? etc?
Edit: Jailbreaking the device is not really an option for us. We have to keep the devices as they are.
Backgrounding
There are several methods to get permanent background execution:
a) Silent audio which is mentioned by JRG-Developer
b) Usage of beginBackgroundTaskWithExpirationHandler + turning location manager on/off (it will reset remaining time to 600 seconds)
Making app invisible
You can use SBAppTags in Info.plist (take a look at this: How to remove app icon programatically from jail broken iPhone app?)
It will make your icon not visible on Home screen.
I've no idea how you can tackle the not be visible on the home screen criteria, but there are certain services that are allowed to be run in the background continuously, notably:
Background Audio (even silent audio)
While this is indeed very hacky, short of jailbreaking the devices, this may be your best bet.
While it's unlikely / very difficult to get past the review process, in the event for some reason you do need to (attempt) to publish this app to the App Store, some apps are even available on the App Store which take advantage of this hack, such as PasteBot.
You should definitely read their write-up here about getting their app's Cut-and-Paste functionality to work while in the background:
http://tapbots.com/blog/pastebot/pastebot-music-in-background
Another out-of-the-box idea, why not use Android devices instead, which do support multitasking?
Two methods:
Jailbreak. A jailbroken iPhone is essentially a Mac and you can use all Mac UNIX programming tricks - spawn a daemon (you can even ask launchd to do that), or something. You can set up enteprise-wise Cydia source. Refer to saurik's website for a walkthrough and set up an experimental server using Ubuntu (which used apt too)
A non-jailbreak way may be possible, but it will depend on what your app is doing. You can try use enterprise-wise push notifications.
Given that this is impossible to do on non jailbroken phones, I'd suggest the following:
develop a directory app, or a phone list app, something that is specific to your company.
have it connect to a web service once a day to register the device ID (so you know the user has not deleted the app)
tell users they need to keep the app open at all times (and if a user's device does not register one day, send them an email asking them to launch the app).
Now you can send back whatever you want with the app. If they kill it, you'll know the next day when you have a script look at the logs.
If you think this is a terrible idea, it is, but its the best you are going to get on iOS right now.
EDIT: you could send a notification every day - say in the AM - to make sure the user opened the app if it wasn't running.
From my experince, this kind of behaviour cannot be achieved on iOS. When an app enters into background, it is active only for a small particular amount of time. After that, it goes into hybernate state. It stops working. So the behaviour you said can not be achieved without abusing iOS workflow. Thats why some call iOS's multitasking as not true multitasking. Only jailbreaking might help your case. That was for one case. The second one where the app cannot be seen on home screen is again, impossible. It has to be on springboard to run.
I have noticed I cannot access the Pasteboard in iOS whenever my device is locked with passcode. I know there was a restriction regarding keychain, but not sure why its affecting pasteboard as well. Is this a known issue or purposeful restriction?
I'm assuming this is desired function.
Imagine an app like 1Password. That app supports copying a password to the paste/clip board.
If I have a passcode set on my device, it's probably because I don't want people to be able to see the data on that device - it could contain stuff like, say, all the specs and launch date for the next iPad.
As a user, I probably shouldn't be copying such information to the pasteboard, but, hey - my device is locked with a passcode, right? No one can see my info, right?
Apple knows that users often use this line of reasoning, and, however flawed it may be, you build your OS for the user - not the user for your OS.*
* Unless you're Microsoft building Windows 8. Then you can break all the rules and make a strange OS.

Programmatically delete my own app
Currently I am working on a iphone application and one of the critical requirement of the application is if a user cannot successfully authenticate after 5 attempts, the application is removed from the user’s iPhone.
How can I achieve this goal?
Being able to alter things outside of the application's own sandbox is a huge security risk that Apple (understandably) has not allowed. Therefore you will not be able to do this. The best you can do is store the result in a persistent value and not allow to app to continue after launching. For bonus points, you can store this value in the iOS keychain so that it will persist between installs if you like, then the user will be forced to reset their ios device to factory defaults to be able to use it again.
Can't be done. The best you can do is to make your app stop functioning after five failed authentication attempts.
you cant. the only one who can have this privilige is the user. You could just make the app to not open anymore, making the user angry and then deleting it afterwards.
Its not possible. You should handle it programmatically like locking the application. Once user is failed for 5 attempts, change your startup viewcontroller and do not allow the user to navigate any where else. Here you can display some message to delete the app.
An application, installed in a non-jailbroken device, is a sandboxed eco-system.
If your app is for App Store, this thing cannot be done. If this app is for a JB device (for In-House apps would be possible, but I think you need root permissions to delete apps), try to remove the app file from disk after the app has gone on background (but I'm quite sure files are locked, so you'll not be able to do it). If this approach, as I guess, doesn't work due to locked files, you can try to search for private APIs.
It's not possible. You only solution is lock the app if authentication not success.
