The NSLayoutConstraint class defines a relationship between two objects. There are different techniques you can use when implementing Auto Layout programmatically. If merge conflicts occur they are in a Swift file, which you’re used to solving, and not in an alienated XML file that Storyboard generates behind the scenes. You can clearly see which constraints are applied. Implementing Auto Layout programmatically is a great solution to these problems. Collaborating with Storyboards is not an ideal experience if merge conflicts occur. Additionally, a big app often means a big team. It’s simple, concise and has almost no learning curve.īut managing Storyboards can become very difficult if you have a big app.
I’m sure every developer has tried making an app via Storyboards. That may sound simple on the surface but, as you’ll see in this tutorial, Auto Layout can get quite complex very quickly! With this in mind, you can use Auto Layout in two forms: via the Storyboard or programmatically. Auto What?Īuto Layout is a system of constraints, or UI-based rules, that govern the size and position of elements on the screen. To make things easier, Apple introduced Auto Layout. Now, developers have to cater to a plethora of screen sizes. With only one device, you only had to cater to one screen size.īut as years passed, Apple introduced more and more screen sizes as well as the iPad. In the beginning of the iPhone era, Apple made only one device: the original iPhone. However, since SwiftUI is still some years away from world domination, you may have to stick with your old friend Auto Layout a little longer. With the introduction of SwiftUI, it’s easier than ever to do so.
#QUARTZCODE HOW TO#
QuartzCode offers you the possibility to draw vector graphics and generate animations by using intuitive tools in a WYSIWYG environment, while also making sure the results can be integrated into any macOS or iOS project without too much trouble.Īll in all, the app is definitely a great choice if you are just started learning how to use the Core Animation library, but also if you want to save time writing code and, instead, having it automatically generated.Making your app look good in both portrait and landscape layouts is something every developer needs to do on a daily basis. Powerful solution for converting vector drawings into Objective-C code without having any programming skills In addition, QuartzCode comes with a collection of sample projects that can help you get stated, and an online documentation that details the capabilities of each included tool. You can preview the results in real time, and you are able to generate the code with a simple mouse click.įor your convenience, QuartzCode also enables you to adjust the canvas size and layout to match the target device. Within the QuartzCode Timeline Panel you have the option to organize the events of your animation, setup timing curves, switch between different keypaths, adjust the animation speed and so on. Create animation timelines and generate the Objective-C code in no time Most QuartzCode capabilities can be easily accessed via the app’s main window which is organized in 4 main areas: the center is reserved for the canvas, on the bottom you can see the animation timeline, while right and left sided panels display the layers included in the project, and the available customization options.Īt the same time, the top toolbar provides access to basic shapes, to the vector, pencil, or text tool, enables you to quickly create effect, replicator, or emitter layers, offers you the possibility to group/ungroup objects and rearrange them on the canvas, and so on. Well-structured animation creator featuring both basic and complex functionality Moreover, the app is able to generate the associated Objective-C code, which means that you can include the projects within your iOS or macOS projects without having to write the code on your own. QuartzCode proposes a clean and organized environment for creating high quality vector animations by employing simple yet efficient tools.
