![]() You can customize the splash screen behavior using the swizzle method - add this file into your Unity project once the project is built and then run it in Xcode you’ll see the results. so we are getting a reference to the methods that we want to swizzle later. Method is an entry to the dispatch table of the class, which maps the Selectors, with their Implementations. we are getting the selectors for the two methods that we need to swizzle. Selector is a C string that represents the name of the method at the runtime. Native part: the framework or code to injectįor this example you can use your framework/ framework.h header file to add the C code We need to use it for bridging #ifdef _cplusplus extern “C”.Wrapper part: To communicate with the native SDK, we need to build a bridge between the Unity C# and the native code, using C++ (.cpp) or Objective-C++ (.mm).Unity part: The Unity project (in our case - the game).Here are the key steps to integrate a Voodoo-native Framework in Unity games using a C# wrapping solution ![]() Case StudyĪ tip : only use this method if you need to, it is not worth doing it for kicks. when Apple forgets a super call :D ! or if we need to do some tricky overrides in app delegate using Unity for iOS. In some cases using swizzling can be the simplest solution, e.g. Because swizzling is not an Atomic Method, it can definitely be difficult to understand and debug. That said, it’s safe if we use it properly and I will explain how we can do so later. I would say 99.999% of the time we avoid using this in our frameworks, as it is a potentially useful but also particularly dangerous approach. So subclassing would be the most preferred way to do the job, and for most scenarios, it probably does the trick.Īs said in nshipster : “swizzling is widely considered a Voodoo technique prone to unpredictable behavior and unforeseen consequences.” Concerning Swizzling, most of the usage will be to extend the functionality of an existing method or to override default behavior. Mopub.) use this SDK wrapping method to adapt their pre-existing native SDK to Unity/C#. so most Ad Networks/Monetisation solutions (eg: Facebook, Applovin. The gaming industry is the ideal market for advertising. Use the Swizzling method… When I say “swizzling”, I mean the act of replacing the original method with our own bespoke method. ![]() Taking into account all the disadvantages and side effects of possible solutions in this scenario, we can make the decision to… So the whole splash screen process is redefined by the Unity engine, which is not accessible from the c# part and this requires us to create some specific native logic. The Xcode native project will be generated by Unity with all the required libraries, precompiled. Like I said, these questions were put together by summarising nine months of messages from readers, so if I missed something off it's probably because I wasn't asked very often or at all.Now, for our purposes, let’s say we want to customize the game’s splash screen behavior in Unity. Why is there nothing about SomeAwesomeClass? So, some questions are easy, some are hard, and some are in between – and that's OK. I've tried to make the answers you see here representative of the questions I get, and it's true: there is a huge range of skills out there. I get a lot of questions from readers every day, some on Disqus, some on Twitter, and some by email. If you're looking for explanation and elaboration, you should read the main Hacking with Swift tutorial series. If you're looking for answers and only answers, this is the right place. I tried to make every answer brief, because when you're looking for answers you don't want to read waffle. You don't need trial and error: everything is written for Swift 5.4. This frequently makes it hard to find answers to common questions, because what worked a year ago is today probably incompatible! So, I made this as a one-stop-shop for 600 of the most common questions I get asked about Swift, and I made sure the answers were fully updated for Swift 5.4. Swift is a language that has changed a lot since its launch, and continues to change with every new Xcode release. Why is this better than just using Google? Yes! You can use this code however you want in your app projects, commercially or non-commercially, and with or without attribution to Hacking with Swift. This follows the same hands-on approach as the Swift Knowledge Base, but goes into much more depth to help you get started faster. SwiftUI is such a big topic that it has its own dedicated guidebook: SwiftUI by Example.
