Improving the Appearance of MFMailComposeViewController in Swift

If you're developing an iOS application and have ever integrated email functionality using MFMailComposeViewController, you may have encountered some challenges with its appearance. Many developers have reported issues with visibility, especially when it comes to the cancel and send buttons which can sometimes be difficult to tap due to their default styling. In this guide, we’ll explore how to enhance the appearance of this essential component within your application to ensure a better user experience.

Understanding the Issue

The MFMailComposeViewController is designed by Apple to provide a standard interface for composing and sending emails. However, some developers notice that its default aesthetic can make it hard to read or interact with, especially in specific contexts like error messages or dark backgrounds. Here are the typical user complaints related to its appearance:

Low visibility of buttons: Buttons for sending or cancelling an email become hard to find and interact with.

Inconsistent styling: Many attempts to customize the view do not yield the desired results, as system controls take precedence over custom UI settings.

As a developer, you want to ensure that your users can interact effortlessly with this view. Thankfully, there are ways to improve its accessibility without compromising its usability.

Solution to Improve Appearance

Recent findings suggest that modifying certain settings can significantly enhance the visibility and overall user experience. Here’s how you can do it:

Step 1: Check Your Accent Color

The first step is to ensure that your app's accent color is set correctly. The accent color influences various UI components, including overlays like MFMailComposeViewController. Here’s how to check and modify it in Xcode:

Open your project in Xcode.

Navigate to the Assets.xcassets file.

Look for AccentColor and make sure it is set appropriately. A poorly chosen color can make buttons less visible.

Tip: If your accent color is set to "none," try changing it back to a distinct color to see if that helps with visibility. This seemingly simple adjustment can have a noticeable impact on your app's UI.

Step 2: Implement the Mail Composer

In your Swift code, ensure that you are presenting the mail composer correctly. Here’s an example of how to implement the function that presents the MFMailComposeViewController:

Step 3: Test on Different Devices

After making the changes, it’s important to test how the MFMailComposeViewController appears on different devices, especially with various iOS versions. While customizing appearance might work for specific versions, keep in mind that Apple regularly updates how UI components are styled. Testing can help you catch any issues before your app goes live.

Conclusion

Improving the appearance of MFMailComposeViewController doesn’t have to involve complex code or deep system modifications. By adjusting your accent color and ensuring proper implementation of the composer in your code, you can significantly enhance its usability. Always remember to test the appearance across different devices to ensure a consistent user experience.
