Open the ViewController.swift file and change the below code snippet into the viewDidLoad() function. Then press the control key click the storyboard uiwebview drag into viewcontroller.swift file and place next to viewcontroller class file, as shown in the below. Then, click the assistance editor to link the Storyboard ViewController page to viewcontroller.swift by adding the uiwebview reference. Now, uiwebview added into Main.storyboard ViewController page and looks like below. Open the Main.storyboard file, then at the right bottom of the Xcode you can find ios webview object in the utility area, drag and drop the uiwebview into storyboard viewcontroller page. first we will add the uiwebview into storyboard viewcontroller.
We can add the UIWebView to View using two methods, first one is adding the uiwebview into storyboard and another one is programatically create uiwebview and adding into the view. Select Swift in Language field and Universal in Devices option, Then press next and create the project. In the next screen, enter the Product Name as “UIWebView Example”, then enter the company identifier details. Open the Xcode, create new project and select the Single View Application template, for more reference you can go through apple documentation for uiwebview. UIWebView object is used the load and display the web content into your application, safari browser is the primary example for ios webview. You just have to add a static variable to a class to keep a shared instance of the class itself, and you are done.In the Previous ios webview example I have explained about creating ios webview using objective-c, but this tutorial we are going to learn about creating and implementing the uiwebview example using swift programming language. The singleton pattern is very quick to implement, especially in Swift, and it works well. As your users navigate through the screens of your app and interact with it, you need to keep a global state that tracks all the changes the user makes to the data.Īnd this is where most iOS developers reach for the obvious, but incorrect, solution: the singleton pattern. State propagation across view controllers is vital in any iOS app. I myself have fallen into this trap in the past. One of the most common iOS development bad practices arises when passing state between the view controllers of an app. I realized that, like many iOS developers, I had succumbed to some classic pitfalls of bad coding practices. From then on, the problems in my code started to stick out like a sore thumb. Not much later, I started reading about some best practices. I had the typical developer hubris: we often think that what we do is great and others don’t get it. I dismissed their judgement, thinking that my code was great and there was no way it could be improved. Although they said the quality of the code was not bad, they pointed to the fact that the code was hard to maintain and to test (unit testing was not very popular in iOS development back then). When their response came back, the verdict was different than I thought. That didn’t bother me, because I thought my code was impeccable and that the review company would say the same. Part of this process involved sending the code of the app I wrote to a third party for review. Big companies, especially banks, usually have processes in place to ensure that their software is secure, robust, and maintainable. A few years ago, when I was still an employee in a mobile consultancy, I worked on an app for a big investment bank.
