ummary:

When creating a UITableViewCell in a xib with AutoLayout on, all constraints created in IB are created for the view and not the contentView of the cell. This has the effect of mangling the layout when entering edit mode.

Steps to Reproduce:

Create UITableView xib, load with UInib

Expected Results:

Constraints should be created for the view not the contentView

Actual Results:

Constraints are created for the view

Notes:

After much saerching i found this post

<http://stackoverflow.com/a/13893146/1983506>

and the following snippet in the UITableViewCell's subclass 

- (void) awakeFromNib {
    
	[super awakeFromNib];

	for(NSLayoutConstraint *cellConstraint in self.constraints){
		[self removeConstraint:cellConstraint];
		id firstItem = cellConstraint.firstItem == self ? self.contentView : cellConstraint.firstItem;
		id seccondItem = cellConstraint.secondItem == self ? self.contentView : cellConstraint.secondItem;
		NSLayoutConstraint* contentViewConstraint =
		[NSLayoutConstraint constraintWithItem:firstItem
									 attribute:cellConstraint.firstAttribute
									 relatedBy:cellConstraint.relation
										toItem:seccondItem
									 attribute:cellConstraint.secondAttribute
									multiplier:cellConstraint.multiplier
									  constant:cellConstraint.constant];
		[self.contentView addConstraint:contentViewConstraint];
	}

}


fixes the problem
