Animations can add visual cues that notify users about what’s going on in the app. In iOS, animations are used extensively to reposition views, change their size, remove them from view hierarchies, and hide them. You might use animations to convey feedback to the user or to implement interesting visual effects. -developer.apple-

In iOS, we don’t need to write any drawing code because apple provides it for us 👏🏻 What we only have to do is trigger the animation and let Core animation handle the rendering of individual frames.

3types of animation

• UIKit
• Core Animation
• UIViewPropertyAnimator

When to use and what to use?

At the end…

I think the first thing you should know before making an app is about the app’s environment or the life cycle of the app. I know you would probably super excited to make your own app after studying basic grammar but i’m sure the app’s quality or the programming skill will stay the same forever

For example, I have played league of legends since high school and i still suck at it. Tbh, my friends are telling me to quit 🤭 I think the reason i’m being looser is that i don’t really tried to understand every champion’s characteristics, role…

TableView is the best way to display a list of data which contains header, footer, and section. It displays a single column of vertically scrolling content divided into rows.

📌 This post will be more about the concept of TableView rather than just making TableView

CollectionView vs TableView

Use context menus to give people access to additional functionality related to onscreen items without cluttering the interface which is similar to Peek and Pop.

📌 Peek and Pop: Accelerate actions in your app by providing shortcuts to preview content in detail view controllers.

Apple is replacing Peek and Pop with context menus in iOS13 and Why is it?

Apple introduced Peek and Pop in iOS 9 and Apple never managed to add 3D touch to the iPad and they have removed it from iPhone models.

Two key differences are:

• Context menus are available on all devices running iOS 13 and later however Peek and Pop is only available on devices that support 3D Touch.
• …

Use notifications to communicate important information to users of your app, regardless of whether your app is running on the user’s device.

There are two types of notifications

• Local Notification: it’s scheduled and managed by iOS devices such as the default app Reminders from iOS.
• Push Notification: it requires a remote computer to determine when and what to send and push these notifications to all of the devices that are registered in the server.

This post will be about Local Notification ONLY because i haven’t studied Push Notification yet! but i will be posting that too soon 🤦🏻‍♀️

Make your app with wonderful animated effects to make your app live!

Hola! There are a bunch of animation libraries that are already provided. What we only have to do is to find the best animation that suits our app and to use it!

One of the animation libraries that i used is Lottie. Lottie is a mobile library for Android and iOS that natively renders vector based animations and art in real time with minimal code.

Sometimes you want to make multiple objects in one group and make it clickable. I brought the simplest way to do it!

You can either use TapGestureRecognizer to your label, views, and many other objects or to use stackView 😈

btw, anyone Interested to read my post about TapGestureRecognizer, please click the link below.

For example, when changing the profile, i just want the user to click within the area between the image and the label to do some tasks but how to make them in one group and how will know if the object is clicked or not?

Detect extended duration taps on the screen, and use them to reveal contextually relevant content.

Long press (aka press-and-hold) gestures detect one or more fingers touching the screen for an extended period of time. You can set for the minimum duration of touching the screen.

How to implement the gesture recognizer?

• Programmatically using addGestureRecognizer(_:) method.
• In Interface Builder.

Long-press gestures are continuous gestures, which means whenever the state changes, the action method will be called.

• UIGesture.Recognizer.State.began
• UIGesture Recognizer.State.changed
• UIGesture Recognizer.State.ended

UIGesture.Recognizer.State.began

when you touch the screen at least minimum press duration (default : 5 sec) with numberOfTouchesRequired within the area(allowableMovement) that…
