突出显示 MFMessageComposeViewController 中的 SEND 按钮

Question

I have generated an MFMessageComposeViewController to send a preconfigured SMS message, and I now want to draw the user's attention to the send button. The user has already initiated the "send message" process from within the app, but they must then press the send button within the MFMessageComposeViewController to actually send the message. The send button in the standard MFMessageComposeViewController is "hidden away" in the bottom corner of the message body where some, not so tech-savvy users, struggle to find it (a fact not opinion, as I have had test users ask what to do next)!

Apple does not allow this message compose interface to be modified, except for certain exceptions. I have looked into the UIAppearance protocol, which provides limited options to modify aspects of the MFMessageComposeViewController , but the options do not apply to the send button.

I have looked into the documentation, and there are options to highlight or focus on interface objects using the accessibility options, but I can not find a way of linking this to the send button within the MFMessageComposeViewController where I have limited access to the UI components.

How do I highlight the send button within the MFMessageComposeViewController , or access the button so that I can draw the user's attention to it?

Answer 1

It's not possible to directly highlight or focus on the send button within the MFMessageComposeViewController using the public API. The only options you have for modifying the appearance of the MFMessageComposeViewController are through the UIAppearance protocol, which does not allow you to modify the send button.

One possible workaround could be to add a custom overlay view on top of the MFMessageComposeViewController that includes a highlighted or larger version of the send button, or some other visual indicator that draws the user's attention to the location of the send button. You could also consider adding a brief instructional message or label above the send button to help guide the user.

Alternatively, you could consider using a custom view controller or interface for sending SMS messages, rather than using the system-provided MFMessageComposeViewController . This would give you more control over the layout and appearance of the interface and allow you to highlight or focus on the send button as needed. Keep in mind that if you choose this approach, you will need to handle the SMS sending functionality yourself.

Unfortunately, it is not possible to directly highlight or modify the appearance of the send button within the standard MFMessageComposeViewController. This is because the interface provided by the MFMessageComposeViewController is not directly customizable and is intended to provide a consistent user experience across all iOS apps.

One solution to consider is to provide additional instructions or guidance to the user before they are presented with the MFMessageComposeViewController. This could include an on-screen message or tutorial that specifically points out the location of the send button within the interface, or providing a visual indicator such as an arrow or highlight box to guide the user to the correct location.

Another option is to present the MFMessageComposeViewController in a modal view controller and add additional instructions or guidance in the modal view controller.

Also, you can use the accessibility options to add a VoiceOver label to the button, which can be read out loud to the user when the button is in focus.

It's worth noting that Apple's HIG (Human Interface Guidelines) discourages from customizing the system's standard view controller. You should try to stick to the standard iOS interface so that the user can feel comfortable and familiar with the app.
