Constraints variable views such as TableView

That's not the answer.
In this case,

The IUITableView is pasted on a storyboard or xib on top of another UIView.
IIUITableView is paired with a UITableViewController and is included in the top ContainerViews.

There are two possible cases.
　In , you can create an outlet that is a constraint but also a constraint as a UI part.Hold down Ctrl and drag it with your mouse.Then
IBOutlet NSLayoutConstraint* tableHeightConstraint;

You can make a declaration like this in the file's controller file.

For more information, see the NSLayoutConstraint Class Reference. It has a property called @property(getter=isActive)BOOL active and
You can control whether the constraint is enabled or disabled.

Therefore, if there are less than 5 cells in the ViewWillAppear of the ViewController source on this screen, enable constraint height 220 and if there are more than 5 cells, disable constraint or make it different
What do you think of course.
　Of course, the frame on the storyboard depends on how it is pasted.
