I am setting up my iOS app to use the new "reader app" external link option, which means we can send people to our website to sign up instead of using in-app purchase.
Our app is written in Objective C.
The documentation from Apple says you need to use ExternalLinkAccount open() in order to spawn a modal window that warns users they are leaving your app. The problem is, I can't figure out how to use this and can't find any examples.
This is the documentation on how to set up a reader app with an external link:
https://developer.apple.com/support/reader-apps/
This is the specific documentation for ExternalLinkAccount:
https://developer.apple.com/documentation/storekit/externallinkaccount
I tried including StoreKit in my .m file but can't figure out how to use ExternalLinkAccount.

Push notifications have been left out of tvOS (understandably so) but the docs seem to contradict themselves in alerting users to the fact that there is something new available in your tvOS app.
Here it seems to say that you can add an app badge: https://developer.apple.com/library/prerelease/tvos/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/WhatAreRemoteNotif.html
Here it says they've been removed from UIKit: https://developer.apple.com/library/prerelease/tvos/releasenotes/General/tvOS90APIDiffs/Objective-C/UIKit.html
Removed UIApplication.applicationIconBadgeNumber
Assuming the badge approach is not supported in this release, does anyone know the best practice for alerting a user that there is new content in your app without the user taking an explicit action? ie focusing on the app and showing them something in TopShelf?
I encountered the same problem and dived into this. Probably your best way is to update the topshelf with latest items, which is my way to solve this for now. You can use network calls to update the topshelf with content from your backend.
This depends on the type of application. E.g. showing the latest top movies for a movies app.
You can trigger an update of the topshelf after your network call completed using the following code:
NSNotificationCenter.defaultCenter().postNotificationName(TVTopShelfItemsDidChangeNotification, object: nil)
Make sure to implement the TVTopShelfProvider which should be clear using the following documentation:
This protocol is adopted by the principal class of an app’s TV Services extension. Apps that implement this extension can provide dynamic content to the Top Shelf element rather than having the system use the static image submitted with the app. The topShelfStyle property specifies the interface style you want, and the topShelfItems property specifies the content items to display. Whenever you change the content provided by the extension, post a TVTopShelfItemsDidChangeNotification notification to prompt the system to reload your content.
Icon badges are removed for app icons, push notifications as well (except for silent push notifications).
I am developing a SandBoxed Cocoa Application. I have successfully implemented the Launch at login feature by using the Core Foundation function:
SMLoginItemSetEnabled
I have based the implementation on This tutorial
But now I need a way to determine if my app is set to be launched at login, so that I can show the button in the appropriate position upon launch. I would expect a similar Core Foundation function to find out if a bundle identifier is on the list of login items, but I didn't find it.
Another problem is that, by using this Core Foundation approach, although it is recommended by Apple, my app is still inconsistent with the "Open at Login" tick in my application dock menu.
You can do it using the functions in the LSSharedFileList.h header, which is in LaunchServices.framework, which is in CoreServices.framework. As far as I can tell, Apple hasn't documented this stuff except in the header comments, but that's probably enough. The basic outline is that you first create a LSSharedFileListRef using the function LSSharedFileListCreate for the list type kLSSharedFileListSessionLoginItems. Then copy a snapshot of the list (which is a CFArrayRef) using LSSharedFileListCopySnapshot. Then for any item in the array, you can get its URL using LSSharedFileListItemCopyResolvedURL. That last function requires Mac OS X 10.10 or later, while I think the others date back to 10.5.
By the way, the docs on SMLoginItemSetEnabled say that it's for setting an embedded helper app as a login item, but it sounds like you're talking about a freestanding app.
Apple's sandbox documentation says:
With App Sandbox, you cannot create a login item using functions in the LSSharedFileList.h header file. For example, you cannot use the function LSSharedFileListInsertItemURL.
But maybe you can still use the shared file list functions on a read-only basis.
I am currently making an app that recommends other apps to download on the apple app store. I assumed that the only way for users to download these linked apps was to call the iTunes URL of the particular app -> the apple app store would then open pushing the original calling app into the background -> then the user would press the download button here as per normal.
Then I was playing with the app "App Hero" and they do something I thought wasn't possible. You can actually download another app to your device without ever leaving the "App Hero" application. I thought this was impossible due to sandboxing. They have a modal segue to what appears to be an embedded app store where you can commence installation of another app. This "embedded" app store doesn't have the usual UITabBar running along the bottom but everything else is basically the same.
Does anyone have any idea how they would have achieved this? It doesn't appear to be a UIWebView, perhaps I am wrong. And is this against any of the apple regulations?
*This is no way an advertisement for "App Hero". I am genuinely impressed/confused how they are able to do this and would love this functionality in my own app if it is allowed.
The class you are looking for is called SKStoreProductViewController. Docs here.
I want to add login items programmatically in Mountain Lion (10.8).
Until now I was able to add login items by editing this plist:
/Users/test/Library/Preferences/loginwindow.plist
and adding items (path,name,hide) to AutoLaunchedApplicationDictionary dictionary
in the OS doesn't work anymore. Items that are added to this dictionary are not launched on login. I see that the login items are saved in a file called: com.apple.loginitems.plist
but I don't understand how to add an item to this file. I tried to add the item to CustomListItems dictionary with parameters like name,path, hide but they were not launched on login.
Does anyone know how can I add from code login item?
I understand you want to start your program automatically when your user logs in.
In older versions of OS X, it was possible to add login items manually by editing loginwindow.plist. Apple deprecated this approach when they added LaunchAgent and LaunchDaemon functionality to the OS.
Since you are using Mountain Lion, the correct way to have a program launch is to create a launchagent for it. This is a .plist file that you can use to tell OS X to a) perform some action (e.g.: launch /some/program.app) when b) a specific event occurs (e.g.: logging in, logging out, etc)
You will find Apple's official document on creation of LaunchAgents over here.
This looks like a great tutorial on the modern way of doing things: The launch at login sandbox project
It starts with a paragraph buried in the App Sandbox design guide:
Creating a Login Item for Your App
To create a login item for your sandboxed app, use the SMLoginItemSetEnabled function (declared in ServiceManagement/SMLoginItem.h) as described in “Adding Login Items Using the Service Management Framework” in Daemons and Services Programming Guide.
(With App Sandbox, you cannot create a login item using functions in the LSSharedFileList.h header file. For example, you cannot use the function LSSharedFileListInsertItemURL. Nor can you manipulate the state of launch services, such as by using the function LSRegisterURL.)
And rolls from there...
I'm looking for an equivalent of Mechanize (Ruby/python and more) for iOS.
I need to simulate a click in a webpage (form submission) and get the response back. I tried to construct a POST-request using ASIHTTPRequest without succes. I was able to create a solution in Ruby (with Mechanize) but I want to be able to do the same in objective-c for iphone development. Any suggestions ?
As described in the duplicated posts, the API to programmatically simulate touches is private, so not appropriate for a shipping app. Follow the links if you want to know how to do it anyway.
