Question

have a little problem with this code:

 UITableViewCell *cell = (UITableViewCell *)[[button superview] superview];
 [button setBackgroundImage: [UIImage imageNamed:@"blueButton.png"] forState:UIControlStateNormal];

 VersionsPopover* content = [[[VersionsPopover alloc] initwithChapter:button.chapter]autorelease];
 UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:content];
 aPopover.delegate = self;
 aPopover.popoverContentSize = CGSizeMake(500,[self filesFromFolderWithChapter:button.chapter] *  60);

This

VersionsPopover* content = [[[VersionsPopover alloc] initwithChapter:button.chapter]autorelease];

is always getting me potential leaks.
With autorelease I get for aPopover “Object sent autorelease too many times”.
When I use [content release] Xcode tells me that I don’t own this object.
Without a release it says “potential leak”.

Don’t know what else I could try to solve this…

Do like this.

VersionsPopover* content = [[[VersionsPopover alloc] initwithChapter:button.chapter] retain];
UIPopoverController* aPopover = [[UIPopoverController alloc]
                                 initWithContentViewController:content];
aPopover.delegate = self;
aPopover.popoverContentSize = CGSizeMake(500,[self filesFromFolderWithChapter:button.chapter] *  60);
[content release];
