由 天大地大妈咪最大 提交于 2019-12-06 16:11:46
I have registration page in my iOS app that I'm trying to write in Swift.

iOS: Strategies for downloading very large data from web

由 自古美人都是妖i 提交于 2019-12-06 13:44:05
I'm struggling with memory management in iOS while downloading relatively large files from the web (such as videos with 350MB size). The goal here is to download these kind of files and store it on CoreData on a Binary Data field. At the moment I'm using NSURLSession . dataTaskWithUrl and NSURLSession . dataTaskWithRequest methods to retrieve these files, but it looks like these methods don't treat problems such as memory usage, they just keep on filling the memory until it reaches its maximum usage, leaving me with a memory warning when I reach 380MB~. Initial Memory Usage Memory Warning What

由 落爺英雄遲暮 提交于 2019-12-06 12:54:10
问题 I use NSURLSessionDownloadTask to download a file from server, it is run in a background session. I want to save resume data to resume the download when the app is terminated.

NSURLSessionConfiguration timeoutIntervalForRequest doesn't seem to work with the background session

由 落花浮王杯 提交于 2019-12-06 12:31:06
The new timeout property of NSURLSessionConfiguration doesn't seem to work when the session is set to work in background (via backgroundSessionConfiguration call). Anybody know if that's really the case? Code snippet: NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration backgroundSessionConfiguration:bgSessionConfigIdentifier]; sessionConfig.HTTPMaximumConnectionsPerHost = 1; sessionConfig.timeoutIntervalForRequest = 60; Do I need to do anything extra for the timeout to work? I just ran into similar problem, fixed it by using timeoutIntervalForResource instead of

NSURLSessionDownloadTask resumes automatically all task while in background

由 荒凉一梦 提交于 2019-12-06 10:40:41
I have requirement to download files in serial order. Currently I am able to do that while app is in foreground. Following is the logic I have used. Create all tasks for downloading. Resume one at a time and as the current finishes resume the next one from URLSession:task:didCompleteWithError: . This logic is working while app is in foreground but once app started to run in background(By crashing) and we again run the app before download finishes all the tasks state has been changed to resume and all are downloading at the same time. Is this the expected behaviour or anything I am missing to
