iPhone SDK: SDWebImageDownloader Crashing

Question

I'm using the SDWebImageDownloader library to download images asynchronously. The problem i'm having is when I click the back button before the images finish download the app is crashing on the following line in the SDWebImage Class:

if([delegate respondsToSelector:@selector(imageDownloaderDidFinish:)])

This is how i'm using it in my code:

sdDownloader = [[SDWebImageDownloader downloaderWithURL:headerImgURL delegate:self]retain];

What is causing it to crash? I'm retaining it and i'm not releasing it anywhere.

Answer 1

When you say you are retaining "it", what do you mean by "it"? If it's crashing with EXC_BAD_ACCESS when you try to send a message to delegate, it's likely that delegate is a dangling pointer because it's being released prematurely. What is retaining delegate? What is releasing delegate?
