Ok -
Here is the offending code that sucks up about 2MB:
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
while(thisState = [statesEnum nextObject]){
UIImageView *singleStateView = [[[UIImageView
alloc]initWithFrame:CGRectMake(2,0, 293, 184)]autorelease];
[singleStateView setImage: [UIImage imageNamed:[[@"wf-map-gray-"
stringByAppendingString:thisState
]stringByAppendingString:@"_glow.png"]]];
[singleStateView setTag:100];
[fruitStateView addSubview:singleStateView];
}
[pool release];
These are little pngs of the states. They are tiny 4KB images
yet when this loop runs it winds up taking up an additional 2MB
Compressed size does not matter. Your images (or at least your image
views) are 293x184, which means that each view is going to consume
293x184x4 (bytes per pixel) = 210.6K. I presume your looking at the
Memory Monitor tool, as the memory used by view backing stores is not
reflected in the memory usage as reported by the ObjectAlloc tool, but
assuming your PNGs are the same size as the view, that 210.6K number
is far more indicative of memory usage than the compressed size.
