Apply brand color

Using the Sendbird UIKit for React, you can customize the appearance of your application by applying your brand color to the UIKit components. This feature allows you to align the user interface with your brand's color scheme, ensuring a consistent and visually cohesive experience for users.

You'll need to have completed the following set up: Send your first message.

Alternatively, you can use the starter code from this GitHub repository. The starter code located in the apply-brand-color/before folder contains the basic setup for the UIKit components.

Once you've completed the set up, your app should look like the image shown below.

We have five colors for primary usage, ranging from primary100 to primary500.

Use a gradient of colors for a smooth transition in your designs. Primary100 is the lightest color, ideal for backgrounds, while Primary500 is the darkest color, perfect for text and important elements due to its visibility. Primary300 is typically used as the main color due to its balanced intensity.

If you only have one primary color, you can generate variations of this primary color using online tools, which can be found by searching for "color shade generator." This allows you to expand your color palette while maintaining brand consistency.

The following is an example of a color palette that you can use for your application. You can replace the hex codes with your brand colors.

Update the AppDelegate.swift file to change the colors of the UIKit components.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    let APP_ID = "YOUR_APP_ID"    // TODO: Specify your Sendbird application ID.

    SendbirdUI.initialize(
        applicationId: APP_ID
    ) { params in
        // This is the builder block where you can modify the initParameter.
        //
        // [example]
        // params.needsSynchronous = false
    } startHandler: {
        // This is the origin.
        // Initialization of SendbirdUIKit has started.
        // We recommend showing a loading indicator once started.
    } migrationHandler: {
        // DB migration has started.
    } completionHandler: { error in
        // If DB migration is successful, proceed to the next step.
        // If DB migration fails, an error exists.
        // We recommend hiding the loading indicator once done.
    }
    
    SBUGlobals.currentUser = SBUUser(userId: "USER_ID") // TODO: Specify your user ID.
    
    SBUColorSet.primary100 = UIColor(red: 168/255, green: 226/255, blue: 171/255, alpha: 1)
    SBUColorSet.primary200 = UIColor(red: 105/255, green: 192/255, blue: 133/255, alpha: 1)
    SBUColorSet.primary300 = UIColor(red: 38/255, green: 156/255, blue: 114/255, alpha: 1)
    SBUColorSet.primary400 = UIColor(red: 2/255, green: 125/255, blue: 105/255, alpha: 1)
    SBUColorSet.primary500 = UIColor(red: 6/255, green: 104/255, blue: 88/255, alpha: 1)

    return true
}
