问题
I'm subclassing my UITableCell in order move the Minus image and the Delete image in EditMode to the oposite direction. It worked great so far but in iOS 6 when I use reloadData on my tableView the minus image jumps to the left side of the cell instead of staying on the right. I have no idea what changed in iOS 6 to trigger that behavior.
I don't know if that's what is causing the issue but I've logged all the origins in iOS 5 and iOS 6 and the only difference was:
iOS 5.0: Log 5 - State 1 And 3: 560.000000 , 0.000000 , 41.000000 , 40.000000
iOS 6.1: Log 5 - State 1 And 3: 808.000000 , 0.000000 , 41.000000 , 40.000000
Here's the code:
.h:
#import <UIKit/UIKit.h>
#define UITableViewCellEditControlOffset 280
#define UITableViewCellDeleteConfirmationControlOffset 250
#define UITableViewCellAnimationOffset 20
#define UITableViewCellAnimationDuration 0.0

#define SmallCellHeight 40
