Thank you everyone!!!! I have this working (locally in memory anyway)... I
had to tweak the method a little bit...
- (UIImage*)imageNamed:(NSString*)imageNamed cache:(BOOL)cache
{
UIImage* retImage = [staticImageDictionary objectForKey:imageNamed];
if (retImage == nil)
{
// Since my images are not local, fetch externally
//retImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]
pathForResource:imageNamed ofType:nil]];
retImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL
URLWithString:imageNamed]]];
if (cache)
{
if (staticImageDictionary == nil)
staticImageDictionary = [NSMutableDictionary new];
[staticImageDictionary setObject:retImage forKey:imageNamed];
}
}
return retImage;
}
And how I am calling it:
UIImage *ret = [self imageNamed:tmp cache:YES];
holder.image = ret;
Seems like it's working pretty well. Although there will always be some
initial stutter on long lists in the table, at least once you've used it a
little things smooth out. If I need to, I'll just use the file system or a
db. Thanks for all of the help here, I really appreciate it!
