To make App icon and Splash image in React Native, I use generator-rn-toolbox until now. the links below are about it.
Until now, I was using generator-rn-toolbox well, I got a comment on my blog post, that there is a new library, from generator-rn-toolbox developer who is very kind.
I have checked it. generator-rn-toolbox is
Deprecated, and he has made and provided new react-native-make.
In this blog post, I will introduce how to make App icon and Splash image via react-native-make library, and compare the previous library.
Execute the command below to install react-native-make.
npm install --save-dev @bam.tech/react-native-make
That’s all. We are ready to use react-native-make. A comparison with the previous generator-rn-toolbox is below.
When install generator-rn-toolbox, we need to install globally like below.
npm install -g yo generator-rn-toolbox
And then, we need to install additional library, imagemagick, like below.
brew install imagemagick
By comparison, we can install react-native-make locally and don’t need to install any additional libraries.
When you use react-native-make to create App icon, you need a
1024x1024 px size
If the file is ready, execute the command below to make App icon.
# react-native set-icon --path [path-to-image] react-native set-icon --path [path-to-image] --background ["color"]
# react-native set-icon --path ./src/Assets/images/app_icon.png react-native set-icon --path ./src/Assets/images/app_icon.png --background "#FFFFFF"
We need to make a Storyboard for the Splash image on iOS. To create the Storyboard, click
./ios/[Project Name].xcworkspace file to execute Xcode.
After Xcode is open, right-click the project name on left top of the project menu, and click
New File... menu.
On the screen like above, select
Launch Screen on the right bottom, and click
When the screen like above is shown up, insert
Save As field, and click
Create button on the bottom right to create a Storyboard for the Splash image.
Create Splash image
When you use react-native-make to make Splash image, you need a minimum
If the image is ready, execute the command below to create Splash image.
# react-native set-splash --path [path-to-image] # react-native set-splash --path [path-to-image] --resize [contain|cover|center] react-native set-splash --path [path-to-image] --resize [contain|cover|center] --background ["background-color"]
# react-native set-splash --path ./src/Assets/images/splash.png # react-native set-splash --path ./src/Assets/images/splash.png --resize cover react-native set-splash --path ./src/Assets/images/splash.png --resize center --background "#FFFFFF"
The resize option default is
contain. And, if you use cover option, the main image should be located 1/3 padding on background image, not to crop the main image.
You can see the image status by each option on the link below.
In my case, I use multiple colors background in Splash image. In this case,
cover options is the best choice to create Splash image.
The reason to make Splash image and to apply it is to manage login or data processing in the background of Splash image.
For this, react-native-make uses react-native-splash-screen.
We can use
react-native-splash-screen to easily control Splash image in React Native not only for react-native-make. I’ve written the blog post about this subject. you can see this on the link below.
For me who design and develop the app by alone, when I created App icon and Splash image, generator-rn-toolbox is very helpful. And I think the new react-native-make is also very helpful.
Let’s try to use react-native-make to easily make App icon and Splash image!
