You might want to look at using a network library that allows you to pause and resume downloads from where they left off, so the user doesn't have to start again from scratch if the download is interrupted. ASIHttpRequest can do this, but it's not supported any more since it doesn't work with ARC. thats not correct anymore. On ARC for ASIHttp, you can use a static library compiled with non ARC environment. Apple documentation The NSURLSession class and related classes provide an API for downloading content.

Standart iOS aplications: can not download data when closed. can download data in limited time when pushed to background. Not enough time to download mb.

When my app is initially downloaded, the user needs to download a large file something like MB upper limit. I definitely can't expect the user to keep the app open till this file is downloaded. This will work just fine. You can also check how much time you have, since apple only enable 10 minutes background tasks. Apps that are transitioning to the background can request an extra amount of time to finish any important last-minute tasks. Executing a Finite-Length Task in the Background. However, such a task is limited to an undefined amount of execution time by the system.

However, a Mb file download may be too large a task in this case. You could use NSURLSession introduced in iOS 7. Apple documentation. The NSURLSession class and related classes provide an API for downloading content. This API provides a rich set of delegate methods for supporting authentication and gives your app the ability to perform background downloads when your app is not running or, in iOS, while your app is suspended. Background sessions let you perform uploads and downloads of content in the background while your app is not running. You can create a background session configuration by calling the backgroundSessionConfiguration : method on the NSURLSessionConfiguration class.

A cool tutorial to use NSURLSession at this link. In one of my apps, I was loading huge amount of data. I definitely can't expect the user to keep the app in foreground until the data is downloaded. I just use following code to get the data downloading while app is in background. Its working properly :- Please go through following steps:. AFNetworking allows you to perform heavy operation in background. AFNetworking Library is a excellent combination of NSURLConnection and NSOperationQueue. This library is used for Asynchronous downloading in the background not affecting the other application.

Reference Source AFNetworking works in Background. Apple Reference Link Apple. Background Execution and Multitasking Apple.

You can know more from this slide. I just do some simple useful modification from the snippet of this slide. Hope this helps. NewsStand applications have an extra time privilege to download when closed or inBackground. Once in every 24 hours, they have a privilege to answer a remoteContentReady delegate call. Building a newsStand application is no different than building a standart iOS application. You will just mark it as newStand application. To receive remoteContentReady signal, you have to send a signal from your serverside c , php, bla bla. Not to every single iOS app. Something like a remoteNotification signal. You may need ssl certification for your website in order to accomplish this. Unfortunately most answers here are outdated in ! iOS 13 reduces the time of -beginBackgroundTaskWithExpirationHandler: to seconds from minutes and also kills the app with adverse effects.

I also consider disabling auto screensaver mode for the duration of the download. More information can be found here:.
