Downloading multiple files writes same data to all files

由 旧巷老猫 提交于 2019-12-06 21:25:29
Attempting to download multiple files from an XML feed. There are several Categories and each category has an unknown amount of images. I create a subdirectory for each category, no problem. When I try to download each file to the respective category, every file is written with the same data for every image there is in the feed. I guess my question is how can I download 1 file at a time to the corresponding directory without overwriting all of the images with the same data? -(void)parsingComplete:(XMLDataSource*)theParser { /* iterate through the Categories and create the sub-directory if it

问题 Can anyone help me in understanding these question : What is the advantage of using Alamofire over NSURLSession/ NSURLConnection? What are the differences between NSURLSession and NSURLConnection? 回答1: NSURLConnection is Apple's old API for doing networking (e.g. making HTTP requests and receiving responces), while NSURLSession is their new one. The latter one is higher level and is generally much easier and involves less boilerplate code to use for most application developers - there's

iPhone - NSURLConnection asynchronous download using URLs in NSArray

由 那年仲夏 提交于 2019-12-06 15:40:23

I want to download asynchronously download images using URLs, that get stored in an array populated using JSON. I get the URLs from a JSON grab off of my database. That works quite well and I can see the URL's being placed into the urlArray, but making the URLConnection to get the image, seems to fail. I can't get any of the images to download, or at least they don't show up in my imageArray. Here is my code and thank you for

由 久未见 提交于 2019-12-06 14:03:51
问题 I want to download a lot of pictures from the server. How can I do this as fast as possible?
