How to make a Pop-up window in an iOS App?

What is App Pop-ups?

Pop-ups in Mobile Applications are the little windows that appear on your Smartphone screens while you navigate the app.
These Pop-up windows serve a variety of purposes within the application. We are going to explore the tools used for creating pop-up windows in native iOS mobile applications.
But first, we are going to discuss the multiple ways in which these pop-up windows offer functionality.

What are Pop-ups used for?

Pop-ups can be made for seeking permission to access location, media, contacts, linking social media, and push notifications. These are reserved to be shown at the right time backed by research and testing to maximize conversion.
Prompts that offer gifts, credits and rewards for inviting friends or rating the app on the "App Store" are also done through pop-ups as well.
From content sensitive pop-up advertisements to permission seeking dialog boxes, pop-ups provide with some vital functionalities within the application.
There are some design merits that also differentiate the kind of pop-ups we develop into our app.
So, some of these pop-ups are designed to fit the size of the content like images and texts and works like templates. While there are others that are interactive pop-ups and can be fed data. Then there are some pop-ups that can redirect you to a different page or different platform altogether.

How to create pop-ups within mobile applications for iOS?

So, if you are looking to add a pop-up screen to your native app there are multiple ways to do it. Mobile app developers always try to find the most efficient ways to introduce functionality in their apps. First, we are going to investigate how to create pop-ups in iOS apps using Xcode.
Xcode is an "Integrated Development Environment" (IDE) platform which is used for creating iOS applications. 

Swift is the structural assembly language used in iOS development. Now IDE is just an intuitive interface for coding and not a necessity. But it does increase the productivity of the programmer and increases their efficiency. Another popular iOS IDE is AppCode.
Now for native mobile iOS apps, you can create pop-up windows using a variety of methods. You can create reusable pop-ups, and multiple segway can lead to your visual controller in which your pop-up exists. These can exist on different storyboards.
The advantage of creating Reusable Custom Pop-ups that can be opened from anywhere is that they can be customized easily. Because the source is in one place so it needs to be modified only once.
Modal pop-ups can be created in the same View Controller or using a separate View Controller. UIView or UIAlertView allows developers to introduce extensive functionality.
You can pass data to your pop-up view controller, pass data back from pop-up using Swift call back, and even pass data into delegate and protocols. There are several resources online that can help even beginners to start cracking on their first mobile iOS app.

How to integrate pop-ups in your User Interface

You need to use a proper analytical tool that can tell you the effectiveness of your pop-ups, for example, you can use "AppSee". Below we have broken down the three most common pop-up integrations for your app and how to go about it.

• Refer to a friend or rate the app
• Push notification
• Data access
  
  

  Refer to a Friend or Rate the App

  When optimizing these pop-ups, keep in mind the smooth flow from the app to the different social media and to the Play Store. And even though you make the flow smooth and convenient, don’t expect the users to just flock over and help you increase the reach of your app. It’s very rare that users would feel like they owe anything to the app. So, if your app is not a viral addiction like Flappy Birds, it will be very rare for them to just share it with their friends. Using Pop-ups, you can incentivize them, but remember it should always feel like value offering instead of a bargain, refrain from using phrases like “complete this task”.
  
  

  Push Notification

  Studies show that most users only really engage with their top three apps and so push notifications have become the only way users interact with some Apps. It’s an effective engagement and retention strategy. In Android, these are quite straightforward and are generally part of the initial list of approvals shown before the install in the Play Store.
  
  

  Data Access

  Again, this is very specific to iOS seeking permission guidelines. It clearly states that even though people enjoy the convenience that comes from apps using user’s information they also want to have a say whether they would like to offer up that information. And with recent scandals of data mining by Cambridge Analytica using Facebooks API, this has turned into a major concern. So, mobile app development companies really need to be tactful when developing pop-ups of this nature.
