Ios – How to adjust the left margin for prototype cells in a UITableView

interface-builderiosobjective cuitableview

If I create a UITableViewController, for example via File → New Project… → iOS → Master-Detail Application in Xcode, a UITableView is created with a prototype cell.

The generated view hierarchy is:

UITableViewController view hierarchy

A left "margin" is automagically created between the Cell's Content UIView left edge and the "Title" text's UILabel element as shown below in orange.

Prototype cell gap

This results in a corresponding margin between the device's screen edge and the UILabel text at runtime:

Runtime gap

So, where is the width of this gap set, and how can it be adjusted?

The controls in the Size Inspector for the UILabel are greyed out:

My preferred option would to be able to set the width of this gap from within Interface Builder, but I would also like to understand where this gap is being set, and how to alter it programmatically.

You just need to set contentInset property of the table view. You can set value according to your need.

self.tableView.contentInset = UIEdgeInsetsMake(0, -15, 0, 0);
