HttpConnection, UITableView and RunLoops and Loading from Disk

Question

I'm loading images in to a large grid on a table view. They are coming from the net, but once downloaded they are cached to disk.

I use this:

[_httpConnection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];

to ensure that they load into view whilst I'm still scrolling. Works fine.

However, when I revisit them and they are loading from disk - I don't have the same scheduleInRunLoop method to use ... well I might, but I don't know where it is.

Has anyone got any ideas?

Thanks

Answer 1

I found the answer.

I can dispatch my selector using modes:

[self performSelector:@selector(imageReadyToDeliver) withObject:nil afterDelay:0]; 

I can use

[self performSelector:@selector(imageReadyToDeliver) withObject:nil afterDelay:0 inModes:[NSArray arrayWithObject:NSRunLoopCommonModes]];
