To do this, select the Table View, and then choose the “Connections Inspector” in the right sidebar.įrom there, just click and drag from the open circle to the right of “delegate” and “dataSource” to the View Controller icon at the top of the view. You can do this programatically, but for this example we will do it using Interface Builder. We will manage the Table View from the initial View Controller, so the next step is to set it as the DataSource of the Table. Linking the UITableView to the ViewController
To do this, just select the cell (it may be easier to do this in the Document Outline to the left”, and while still showing the “Attributes Inspector”, set the Reuse Identifier to “PlainCell”. UITableViewCellĪs we also want to populate the cells with some data later on, we will make use of the dynamic prototyping in Interface Builder, to design the cells.įirstly we will set a “Reuse Identifier” for the cell, this is so that we can reuse the same cell prototype when loading the TableView. Then we set the style to grouped, so we can see each section better visually.

So select the Table View, and then click to show the “Attributes Inspector” from the right sidebar.Īll we are doing with these settings, is making the cells in the table dynamic, so that we can update them with live data later on. Now we need to configure the Table View so that we can manage it later on. This will simply make it fit to the edges on any screen size. Once you constraint view appears, select the four lines around the square at the top, while making sure each value is 0. It is the icon with a square, which has a vertical line either side. Select the Table View, and then open up the “Add New Constraints” view from the bottom right corner. Just drag the corners of the TableView so that it fills the view, but keeps the top status bar visible, it should automatically align. Then to make sure it works on all iOS devices and screen sizes, we’ll set up the layout. Putting a UITableView on the ScreenĬlick on the “Main.storyboard” file, and from the object library on the right, drag a Table View onto the view (There should only be the one). This will create all the necessary files, such as “AppDelegate.swift”, “ViewController.swift”, and “Main.storyboard”. Just make sure the Language is Swift, and the other options aren’t needed for this example. Then you can give it a name, for this example I’m using “TableViewExample”. So create a new iOS project, and select the “Single View Application” template.
However in the “Grouped” style, the sections are visually separated into groups, with the addition of a background colour. There aren’t many differences, but in the “Plain” style, each cell fills the Table, and the relevant header/footer float above the cells. There are various ways in which you can customise the style of the TableView manually, but there are two main styles that you can choose from in the InterfaceBuilder, “Grouped” or “Plain”. However in this guide, we will just be focussing on the DataSource, as this is all we need to populate a TableView with data. The UITableViewDataSource is as you may of guessed, what controls the data that populates the table, and also configures the cells in the Table View. The delegate is what manages the interactions on the table cells, such as selecting and reordering. They are the UITableViewDelegate, and the UITableViewDataSource.
With a UITableView object, there are two ways in which you can control them. Basically, it’s a list of cells, that you can take complete control over. UITableViewĪs Apple say in the documentation, “A table view displays a list of items in a single column.”.

In this short guide, you will find out how to create a UITableView, and populate it with your own data. In most iOS applications, you will probably need to use a UITableView at some point. This article is part of a collection of articles about Swift Basics, where I try to explain different parts of Swift development in a more understandable way.
