Hello, I am developing a driver-based application targeting iOS 14+, where users receive time-sensitive trip offers (approximately 10–15 seconds to respond). We would like to implement behavior similar to approval-based apps (e.g., MyGate-style interaction), with the following requirements: When the device is locked: A highly visible notification that allows quick Accept / Decline action. When the device is unlocked (foreground or background): A notification that remains prominently visible (sticky-style) at the top of the screen until the user takes action (Accept / Decline) or the offer expires. Our goal is to ensure the offer remains noticeable and actionable within the short response window. I would appreciate clarification on the following: On iOS 14, is there any supported mechanism to present a true full-screen blocking interface while the device is locked (without using CallKit or Critical Alerts entitlement)? Is there a supported way to make a notification persistent or non-dismissible until the user takes action or the offer expires? Are there any App Review concerns with presenting a blocking modal immediately after the user interacts with a notification? We want to ensure full compliance with Apple’s platform guidelines and avoid unsupported or discouraged patterns. Thank you for your guidance.
