Question

I have developed an application that fetches the feed from a sever, displays the list of feed and on selection of a particular feed, options for sharing to twitter or Facebook is displayed. On selecting one social network, user is able to upload that.

Until this it is fine.

But now I am stuck with an issue. The php i am parsing to fetch the feed has links for some images. I want to take the first five images from the php and display in UIImageView. This also should be auto-updated as and when the new contents are uploaded.

Please let me know how can I do it.

Since, I have a bit of urgency, a demo code will be very useful for me.

Lets say you are getting url of your image from php.

NSURL *url             = [NSURL URLWithString:@"http://img.abc.com/photo.jpg"];
NSData *data           = [NSData dataWithContentsOfURL:url];
UIImage *image         = [UIImage imageWithData:data];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

This will populate your imageView. If you receive any updates from backend, repeat this piece of code & you should be good…

If you want some image caching too the as Shubhank suggests SDWebImage is a good option.
