iOS TableView和prototypecell约束无法正常工作

Question

I have a tableView with a prototypeCell.

I have added constraints to make the tableView take up the whole view:

I've added a "grey area" to the bottom of my prototypecell that take up 100% of the width.

However when i run the app there is a large area above the first tableCell, and the grey-area doesnt have 100% width:

What have I done wrong? Constraint issue?

Answer 1

You should uncheck Constrain to margins and may be adjust your constraint's values to make your grey view full width.

Regarding white space on top - looks like it's something wrong with your tableView settings, not cells
