Summary
When working with -[UIView systemLayoutSizeFittingSize:], one is currently required to toss additional required constraints into the mix, when e.g. calculating preferred heights for UITableViewCell instances in -[id<UITableViewDelegate> tableView:heightForRowAtIndexPath:].

While this is entirely feasible, it’d be nice to specify such things directly in one API call.

Getting back to the tableViewCell example, I’d love to have something akin to the following on UIView:
- (CGFloat)systemLayoutWidthForHeight:(CGFloat)height atPriority:(NSLayoutPriority)priority;
- (CGFloat)systemLayoutHeightForWidth:(CGFloat)width atPriority:(NSLayoutPriority)priority;
- (CGSize)systemLayoutSizeForSize:(CGSize)size atHorizontalPriority:(NSLayoutPriority)horizontalPriority verticalPriority:(NSLayoutPriority)verticalPriority;

Comments

Addressed in iOS 8

I believe this has been addressed in iOS 8 with:

- (CGSize)systemLayoutSizeFittingSize:(CGSize) withHorizontalFittingPriority:(UILayoutPriority)priority verticalFittingPriority:(UILayoutPriority)priority;
