Tab Bar Customization iOS Tutorial

Tab Bars provides the ability to quickly switch between different sections of an app. In this tutorial the look of the Tab Bar and its items will be customized. This tutorial is made with Xcode 10 and built for iOS 12.

Open Xcode and create a new Tabbed Application.

For product name, use IOSTabBarCustomizationTutorial and then fill out the Organization Name and Organization Identifier with your customary values. Enter Swift as Language and choose Next.

Go to the ViewController.swift file and change the viewDidLoad method to

override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. guard let tabBar = self.tabBarController?.tabBar else { return } tabBar.tintColor = UIColor.white tabBar.barTintColor = UIColor.black tabBar.unselectedItemTintColor = UIColor.yellow guard let tabBarItem = self.tabBarItem else { return } tabBarItem.badgeValue = "123" tabBarItem.badgeColor = UIColor.blue }

The tintColor of the Tab Bar is set to white,  and the barTinitColor is set to black. When an item is unselected, its tint color is set to yellow. Each item can have a supplementary badge. Here a blue badge is created with the value of "123".

Build and Run the project, to see the visual customization of the Tab Bar.

You can download the source code of the IOSTabBarCustomizationTutorial at the ioscreator repository on Github.

Day17:TwitterUI Copy 

UINavigationBar, TabBarController, UITableViewを用いてTwitter UI Copy

UINavigationBarのレイアウト対応と、コンテンツの中身はこれから

[samanthavaldivia-demos-blog]

The main goal of my project was to parse YouTube videos into my application. Displayed above is a demo video and splash screen. Note: this video was captured mid development. There is now a TabBarController with more information about Bowdoin Sports and two navigable in- app web links.

There is a UITableView with necessary constraints and IBOutlet that allows for a reference to the table view. Each cell has a customized label and image that is synonymous to the video the user will be expecting to watch once it is clicked. The video data was collected using a subclass of NSObject, which allows the application to have strings, numbers, arrays, and dictionaries. The video model class is also responsible or supplying the video objects to the view controller, allowing for communication with the model to retrieve the necessary data. The Video data in my application is created when the UITableView will ask the ViewController for the data it needs; for example, the number of rows needed for the datasource.  The video thumbnails are added using the individual URL of the thumbnail to display in the cells UITableView. A similar procedure was used for the label and label view for each of the videos. There are also modifications to the row height and width in order to fit the thumbnail, label, and label view.

Tab Bar Controller iOS Tutorial

The UITabBarController class implements a specialized view controller that manages a radio-style selection interface. This tab bar interface displays tabs at the bottom of the window for selecting different views. In this Tutorial a Tab Bar Controller will be created and by default two Tab Bar Items will be included. The third Tab Bar Item will be added using the Storyboard. This tutorial is made with Xcode 10 and built for iOS 12.

Open Xcode and create a new Tapped App.

For product name, use IOS12TabBarControllerTutorial and then fill out the Organization Name and Organization Identifier with your customary values. Enter Swift as Language and choose Next.

For the Tab Bar items some custom images will be used. Download the images, unzip them and add the images to the Assets Library. Go to the Storyboard. In the Document Outline select the First Bar button Item in the First Scene and go to the Attribute Inspector. In the Bar Items section change the title to "Red" and select the book image.

Repeat this step for the Second Bar Item of the Second View Controller. Name it "Blue" and select the clock image.

Select to the Red View and change the Background to red using the Attributes Inspector. In the blue view change the Background to blue. Also remove the Labels inside the view.

The Storyboard should now look like this.

Build and Run the project, and change views by clicking the Tab Bar Items.

Next, we will add another Tab Bar Item inside the Storyboard. Drag a View Controller from the Object Library to the Scene. Select the View Controller and go to the Attribute Inspector. Change the Background color to Green. Next Ctrl and Drag from inside the Tab Bar Controller to the newly created View Controller and select "view controllers" in the Relationship Segue section.

In the Document Outline select the Tab Bar Item in the Item Scene and Go to The Attribute Inspector. In the Bar Items section change the title to "Green" and select the crown image.

Build and Run the project, the 3 Tab Bar Items will be visible. By clicking the Icons the Views will change.

tab bar가 scroll view의 밑부분을 가리는 문제를 해결하는 방법

https://stackoverflow.com/a/19325718/3151712

약간의 문제가 코드에 있어서 수정했다.

let adjustForTabbarInsets:UIEdgeInsets = UIEdgeInsetsMake(0, 0, (self.tabBarController?.tabBar.frame)!.height, 0);

        self.scrollView.contentInset = adjustForTabbarInsets;

       self.scrollView.scrollIndicatorInsets = adjustForTabbarInsets;

두가지 방법이 있는 것으로 추측된다. 

1. selectedIndex에 새로운 index 값을 할당

self.tabBarController.selectedIndex = 1;

2. selectedViewController에 view controller를 할당한다. 

My opinion is that selectedIndex or using objectAtIndex is not necessarily the best way to switch the tab. If you reorder your tabs, a hard coded index selection might mess with your former app behavior.

If you have the object reference of the view controller you want to switch to, you can do:

tabBarController.selectedViewController = myViewController

Of course you must make sure, that myViewController really is in the list of tabBarController.viewControllers.  <- 주의사항
