The arrows between the tab bar controller and the view controllers it contains represent the container relationship. The icon shown below, in the middle of the arrow body, signifies that they have an embed relationship. First, the error message mentioned the name of your storyboard, Main , explicitly.

This drop-down will only show the storyboard files in your project. Keep Main as the selected value and move to the next step: Identifying the specific view controller you want to start with inside that storyboard. On the right, select the Attribute inspector. Also, an arrow will appear on the left of the view controller.

Xcode comes with a template for building a tabbed app: The Tabbed Application template. Currently, the two screens attached to the tab bar controller are both UIViewController instances. Click the first view controller in the Document Outline to select it, then delete it. Drag a new table view controller into the canvas where the previous scene used to be:.

You could have dragged in a navigation controller from the library and embedded the table view, but this Embed In command is a nice time-saver for a common action.

Notice that embedding the table view controller gave it a navigation bar. Deleting the first scene also deleted its relationship with the tab bar controller. But now, you want to recreate it. To do this, Control-drag from the tab bar controller to the navigation controller. When you let go, a small pop-up menu will appear. Choose the Relationship Segue — view controllers option:. This creates a new relationship arrow between the two scenes. This is also an embed relationship, like the one you saw earlier.

The tab bar controller has two embed relationships, one for each tab. The navigation controller itself has an embed relationship with the table view controller. When you made this new connection, a new tab was added to the tab bar controller named Item. For this app, you want this new scene to be the first tab, so drag the tabs around to change their order:.

How to set the title in a Navigation Bar | iOS Dev Diary

Build and run to try it out. The first tab now contains a table view inside a navigation controller. In their current state, the tabs are not expressive at all. Each should have its own icon and name to represent its views. This instance defines the name and the image that should appear on the tab bar.

In the Document Outline, under the Item 2 Scene , you will find an item named Item 2 that has a star icon beside it. Select it and, in the Attributes inspector , change its Title to Gestures. Now, try another way to set the title. In the navigation controller, double-click the word Item at the bottom of the tab bar and type the new name Players. You can add the images now.

Finally, add two labels within the Vertical Stack View. This is where Auto Layout comes in. Select the Horizontal Stack view you added in the cell, then click on the Add New Constraints button that looks like a tie fighter. That button will open a dialog that lets you specify constraint values. Specify the constraints to add for the Stack view as follows:.

With each set of constraints you add, the controls on the storyboard adjust their positions to match. Sometimes, Xcode is able to suggest the constraints you need to add to fix it. Click on the small red circle and it will show you the layout errors. Click the new red circle and tap Change Priority. Change the font size of the lower label to 14 and set the image of the Image view to 4Stars. Then, use the Size inspector to change the default height of the cells in the table view to 60 and uncheck Automatic for both the table view and the cell.

You can either duplicate the cells you just created or tell the table view to show more. Your last step is to give your cells some real data. In case if you have any database related operations in your application select this option otherwise unselect the option. In case if you need unit tests for your application then select this option otherwise unselect it. Once we click on Next button new dialog will open in that we need to select the location to save our project. Once you select the location to save project then click on Create button like as shown below. After click on Create button the Xcode will create and open a new project.

In our project Main. Now in project select Main. Now select ViewController. Now we will add controls to our application for that open Object Library. The Object Library will appear at the bottom of Xcode in right side. In case if you don't find Object library, click on the button which is at the third position from the left in the library selector bar like as shown below. As we discussed our user interface will be in Main. Now in object library search for the View Controller in Filter field then drag and drop the View Controller into Main.

Once we done with adding controllers our Main. Now drag the Bar button item from Object library and drop into first ViewController and click on Bar Button Item and change the name of buttons like as shown below. Now we will make connection between controls and ViewController. Swift code for that click on assistant button overlap circle in Xcode toolbar right side corner like as shown below.
