Issue #210 Depending on what features we want to achieve, we need to go with either AVFoundation or MediaPlayer framework. As someone who worked with many apps that involve media playback, here are some of my observations MPMoviePlayerController vs AVPlayer At first, I use MPMoviePlayerController because it is very simple, in fact, it is a wrapper around AVPlayer. It offers a lot of useful notifications and properties. But when my requirements change, a lot more features are needed, I need to change to AVPlayer to have more control....

Issue #209 Here are what I learn about reachability handling in iOS, aka checking for internet connection. Hope you will find it useful, too. This post starts with techniques from Objective age, but many of the concepts still hold true The naive way Some API you already know in UIKit can be used for checking internet connection. Most of them are synchronous code, so you ’d better call them in a background thread...

Issue #158 We ’ve been using CircleCI for many of our open source projects. Since the end of last year 2017, version 2.0 began to come out, and we think it’s good time to try it now together with Swift 4.1 and Xcode 9.3 The problem with version 2.0 is it’s so powerful and has lots of cool new features like jobs and workflows, but that requires going to documentation for how to migrate configuration file, especially Search and Replace Deprecated 2....

Issue #154 The most common UI element in iOS is UITableView, and the most common task is to display the UITableViewCell using the model. Although the title specifies UITableViewCell, but the problem involves other views (UICollectionView, custom view, …) as well There are many debates about this, so here I want to make a summary, all in my opinion It started with UITableViewCell Is Not a Controller This article follows strict MVC and states we should not pass model object to cell and let cell manipulate directly on the model....

Issue #144 There are times we want the same UIViewController to look good when it’s presented modally or pushed from UINavigationController stack. Take a look at BarcodeScanner and the PR https://github.com/hyperoslo/BarcodeScanner/pull/82 When it is presented, we need a header view so that we can show a title and a close button. We can create a custom HeaderView that inherits from UIView or either embed it in a UINavigationController before presenting....

Issue #124 We all know that there’s a potential crash with UIVisualEffectView on iOS 11. The fix is to not add sub views directly to UIVisualEffectView, but to its contentView. So we should change effectView.addSubview(button) to effectView.contentView.addubView(button) Here we don’t need to perform iOS version check, because effectView.contentView works for any iOS versions. Potential cases for crashes Here are some cases you can potentially cause the crashes Strange namings Normally we name our UIVisualEffectView as blurView, effectView....

Issue #119 This is about collection update, how to provide correct IndexPath and a simple diffing algorithm Excerpt from my talk at CocoaHeads, Oslo https://www.meetup.com/CocoaHeads-Oslo/events/244892347/ Slide https://speakerdeck.com/onmyway133/collection-update CollectionView It’s hard to imagine of any apps that don’t use Table View or CollectionView. And by CollectionView, I actually mean UICollectionView 😉 . Most of the time, we show something with response from backend, then potentially update and insert new items as data changed....
