Figure 8-26. Aligning the User Name label

The final object that needs to be added to the cell is a label for the tweet content. Drag in a label, and position it just below the User Name label. Make it the same width as the User Name label, and then increase the height until the margin guidelines at the bottom of the cell appear. It should resemble Figure 8-27.

Figure 8-27. Aligning the tweet Content label

In the Attributes Inspector, set the Text attribute to Content and the Lines attribute to 2. Xcode will wrap the text onto a second line if needed. If the text length exceeds what will fit on two lines, the Line Breaks attribute will determine what will happen. The default option is Truncate Tail, which cuts the text short and appends an ellipsis or … to the end of the text.

To align the interface elements, click the Resolve Auto Layout Issues button. Under All Views in TweetCell, choose Add Missing Constraints.

You’ve now built the interface for the custom cell. Next you need to create the outlets for the three objects. Open the Assistant Editor with the cell selected, and this time ensure that the code file that is loaded is TweetCell.swift; it’s likely that the file loaded is actually FeedViewController.swift. Click the file name on the jump bar, as shown in Figure 8-28. and then choose TweetCell.swift.
