I'm developing an iOS keyboard extension, it works well when full access enable at the first time.
But can't load when full access disabled on first time.
Does anyone know why?
I've trusted the provider's profile.
third party keyboard works without full access but it depends on code you have written, for example i have stored data in custom shared container and with ID-s i can retrieve them and re-create as UIImage but if i have no full access enabled then i have issues like this: NSUserDefaults are not saving data to shared app group, cant play sounds (in iOS 9 you can), cant use UIPasteBoard for pasting something.

Is it possible to read the contents of another application installed on an iPhone? What about from an extension or keyboard?
I'm trying to come up with something that 'checks' other apps to see if they have any deep links (like Twitter's Twitter://timeline that takes users straight to the timeline in the Twitter app).
Is there any smart way to check a given app for deep links?
Is it even possible to peek at another app's contents from within my app? I suspect no.
If no, what about making a keyboard or extension of some sort that I can access from an app like Twitter and see its contents, such as a URL deep link?
You don't have much options, you may use -canOpenURL:, but, since iOS9, must include special credentails listing all the custom schemes you want to check.
You can't read other app's contents on a non-rooted device unless this app is sharing a keychain (so it can exchange data via the shared keychain). The same thing goes with extensions.
iOS has some high bars on security, so, don't expect much or even, anything.
Something you may want is IntentKit. Also there are ideas around the web about standard url query format like MobileDeepLinking.
I am developing an application for security purpose which has 1 requirement as "Wipe out iPhone or i pad data completely if device is stolen".
While doing search for this functionality, I came across one application "Find My iPhone" here which supports this feature of "remotely wipe out all data".
(http://www.howtogeek.com/77158/how-to-remotely-lock-or-wipe-your-ios-5-device/)
But i want to this functionality through programmatically in my app.Can someone give me a solution for this problem?
And is it possible to do this functionality through programmatically?
You cannot completely wipe a standard iPhone's data from an app. The app runs in a sandbox environment so you cannot access data from other apps or iOS itself meaning that you cannot wipe it. That being said, you could wipe photos and contacts programmatically as long as the user grants you access to contacts and photos.
There is NO WAY that Apple would let programmers wipe data remotely for the entire device.
Instead of doing that, maybe you should have functionality in your app where if server returns a particular flag, you would delete all the data stored locally on your app, by you (like login details for your app, personal data stored in Documents). I suggest that, because I've done it before.
I'm working on adding the ability to use the share button to allow users to save files for use with my main application. Multiple file types (image, video, audio, pdf, etc) need to be supported.
A general use case would be:
The user takes a picture with the standard Camera app or audio recording using the Voice Memos app.
User clicks the Share button and selects my extension from the share list.
Dialog opens up giving the user to opportunity to give a description for the file.
File is saved to where my main app (the containing app) can later access and process it.
I've been able to get to the point where I am prompted to share the file, but I have not been able to find a location to successfully save to that my main app can later read from. Is this even possible? Is there a better way to handle this scenario?
I am currently doing this using Xamarin so debugging is not supported (and logging is minimal). If someone has an answer in Objective C, that would at least help point me in the right direction.
There are a few things that you need to do.
First, your app and your app extension should belong to the same app group:
https://developer.apple.com/library/prerelease/ios/documentation/Miscellaneous/Reference/EntitlementKeyReference/Chapters/EnablingAppSandbox.html#//apple_ref/doc/uid/TP40011195-CH4-SW19
Then you can access the shared storage with something like this:
var groupUrl = NSFileManager.DefaultManager.GetContainerUrl ("stackoverflow.com.mygroup")
Now you can access files in the directory pointed by groupUrl.

I wrote an iphone app that as a first function allows the user to download files. The user then manipulates these files in a particular way that wants them to be in memory.
It's not necessary that all of the files the user gets are in memory, just a few at a time that are well within memory constraints. However, the option to download the rest later is not available because of location assumptions (mainly that there is no assumption the user will be within wifi or data reception).
Is there a way around this? One example would be to have some sort of permanent write that I could access. Is that how the file storage apps solve this?
Thanks.
Could you use a server to do the manipulation instead of the app? iphone app sends the link to the server, server does the manipulation, and the the iphone downloads the manipulated link.
I am curious if it is possible to make an app that adds a functionality to an existing app on ipad, say safari. If yes, which function would add a button to safari?
My question is based on 2 app advertisements I saw, one added a button to safari, the other created an app itself. I didnt buy them yet, so I dont know if they really do what thet say.
Thanks
As far as I'm aware, I think the closest you get to adding functionality to an existing app would be creating a new app that allowed interaction with certain document types.
For example, you might create an app that can open and read PDF documents. On installing this app, you would then find that interacting with a PDF document on any app (such as in an email attachment, or opening a PDF in Safari) would show a new option to open the PDF in your app. This kind of interaction is achieved via the UIDocumentInteractionController class.
Beyond that, I believe you would have to create your own app from scratch based on an existing one in order to extend functionality (so, create the 'MyBrowser' app to behave like Safari, except with additional controls and features).
I'd love to be proven wrong, however.
