ios - How do I adjust the left margin for prototype cells in a UITableView?

Question

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:

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.

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

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.

Answer 1

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);
