At first, I was a little concerned, just one more thing to add to my to-do list, yet a very important one that could keep us from launching our React Native application to the App Store. After my initial reaction, I realized we had a couple of months to figure this out.
When I decided to spend a little time to see how difficult this might be I did not find a lot of documentation for a non-native developer. One of the allures with React Native is that you don’t have to know the nitty-gritty for both iOS and Android, but it can also mean we aren’t as comfortable with some of the tasks that require us to dig into the native side. Spoiler alert, it wasn’t as difficult as I expected, once I figured out the secret. Here is what I learned!
Great! I created my Storyboard file! By default, it set me up with the name of my Application and the Copyright footer. Here is what I had as a starting point with my storyboard. But what next? How do I add my image?
To add the image to your storyboard you drag the item from the left on to your canvas. Once it is there you can start to manipulate it. For demonstration purposes, I have a drastic difference here with the background white and a large image. You can see it here on the iPhone 11.
But if I were to change my display, to say an iPad, things start to look really off! The image we imported is now in the upper left of the iPad display, I see the text I was not seeing before and obviously this is not a consistent user experience based on different devices. Let’s look at how we can make our Splash Screen a consistent experience across devices!
To ensure we have a consistent look we will want to add constraints. Many properties can be used to fine-tune your storyboard, but we will keep it simple.
In the bottom right of the storyboard window, you will find a few icons which I didn’t immediately see in dark mode. The simplest constraints we can add are for horizontal and vertical alignment.
Once I have applied these constraints you can see that I now have the cross hatches displayed on my storyboard to show the view is locked into these constraints. You can also see that when I changed my view back to the iPhone 11 that my image stays where I expected.
These are just the basics of using storyboard! You can get much more detailed with your text and images while creating a consistent user experience across devices.
After I went through this the first time I decided to take what I learned and apply it to another project. Great news, I was able to accomplish this within a matter of minutes! My hope is that with this knowledge, you will be able to accomplish this task just as quickly.
