Apple Inc. (commonly known as Apple) is an American multinational technology company headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software, and online services.
I was searching the web for answers on how to give the CurlUp / CrossDissolve / FlipFromRight / FlipFromLeft / CurlDown / FlipFromTop / FlipFromBottom transition effect for the UITabBar Tab Switch.
I found this answer, but it has a bug or a black screen when you tap on the same tab twice, i.e., the destination and current tab are the same.
So I solve this issue with my logic and additional if and else statement.
So here is the final answer without any bugs.
Step 01: Add these two classes as Super Class to your UITabBarViewController
UITabBarController, UITabBarControllerDelegate
Step 02: Now add the following code to your viewDidLoad Function in your UITabBarViewController
Assumption: I assume you have embedded UINavigationBar inside your Apple iOS app on Storyboard.
If you want to mimic the behaviour of the Apple Safari iOS App, such as hiding the navigation bar on the scroll, you can do it in just a single line of code without any hassle.
You have to add the following code in your View Controller’s viewDidAppear function where you have added UINavigationBar in the Storyboard:
Assumption: I assume you have deployed UITabBarViewController in your iOS App. Now you want to change the Tint color of the UITabBar, the Tint color of the UITabBar item, and the tint color of the UITabBar’s unselected icon.
Doing this is just as simple as a single line of code.
The code below will go to your Apple iOS app’s AppDelegate.swift file under the ‘didFinishLaunchingWithOptions’ function.
Assumptions: I assume you have already embedded in UITabBarViewController for your ViewController in Interface Builder. You also have three tab bar items with individual view controllers and created image assets with your icons.
Copy the following code using your current View Controller’s ViewdidLoad method.
Let’s assume you use Tab Bar View Controller in your Xcode Project.
You have embedded in your view controller with UITabBarViewController.
Say you are using 3 Tab Views.
In Swift programming Language, number counting starts with 0, so you will write code like this in your respective view controller’s viewDidLoad function.
While we use app development methodologies like MVC (Model, View, Controller), we encounter problems navigating from one view to another. How do you change the text of the back button, which gets populated automatically by the Apple iOS operating system?
You can use the below method in the viewDidLoad method of your root view:
We will explore ways to identify the user’s iPad or iPhone device. With the latest Xcode build, we will do all this in Swift Programming Language.
iOS devices will be identified in four ways: .phone, .pad, .tv & .unspecified.
So the code will look like this in swift
Code for iOS 13, iPadOS 13, macOS 10.15 Catalyst and above:
if UIDevice.current.userInterfaceIdiom == .phone {
} else if UIDevice.current.userInterfaceIdiom == .pad {
} else if UIDevice.current.userInterfaceIdiom == .carPlay {
} else if UIDevice.current.userInterfaceIdiom == .tv {
} else if UIDevice.current.userInterfaceIdiom == .unspecified {
}
Code for iOS 12 and below:
if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.pad) {
print("It's iPad")
// Your code here
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.phone) {
print("It's iPhone")
// Your code here
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.tv) {
print("It's Apple TV")
// Your code here
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.unspecified) {
print("It's Unknown Device")
// Your code here
}
Introduction to StoreKit and Apple App Store policies
I will write down a few concepts & ideas to help you understand how to implement StoreKit app review functionality in your app using Xcode.
Important Points to Remember
You can ask your users to rate your app on a scale of 1 to 5 stars. Users can also choose to write reviews for iOS and macOS apps.
Developers can view, sort and respond to reviews in iTunes Connect.
About Summery of Ratings
Every App Store app has one summary rating on the product page, specific to each territory on the App Store.
The developer can reset your app’s summary rating by releasing a new version of the app.
The right way to ask for Ratings and Reviews
The developer can ask users to rate and review your app when they are most likely to feel satisfied, such as when they have completed an action, level, or task.
This will give users an easy way to provide feedback on the App Store without leaving your app.
The developer can prompt for rating a maximum of three times in 365 days.
Users will submit a rating through the standardised prompt.
Presenting the Review Prompt
Although you should call this method when it makes sense in the user experience flow of your app, the actual display of a rating/review request view is governed by App Store policy. In addition, because this method may or may not present an alert, it’s not appropriate to call it in response to a button tap or other user action.
When you call this method in development mode, the review request view is always displayed so that you can test your app on your device. However, this method will not be called when distributing your app using TestFlight.
When you call this method in your App Store-published app, a review request view will be presented, and the operating system will handle the entire presentation process.
I am now documenting some thoughts about black colour behaviour on Physical Paper & computer displays or screens.
I was from a BFA (Bachelor of Fine Arts) – Applied Art background, so we had subjects like Illustration, Calligraphy, Typography, Print Media Design, Logo & Symbol Design, Branding & Identity Design.
We used to design our assignments using Japan Black ink which is very dark in contrast & which creates high contrast reach feeling of black colour tone on white paper.
So when we print our designs in Adobe Illustrator or CorelDraw, we fill the design with (CMYK) Cyan: 100%, Magenta: 100%, Yellow: 100%, K(Black): 100%, then using only K: 100%. These CMYK values use to create high-contrast Japan Black ink fill on White Paper.
