Solving an Animated Icon Bug on iOS with Transform and Tooltips

TL;DR

• iOS vs Android Discrepancy: Transform and size on animated icons behave inconsistently across platforms.
• Impact of Props: Style and tooltip props mess with animation on iOS.
• Debugging Approach: Isolated props, verified tooltip constraints, and experimented with UI libraries for resolution.

Engaging with platform-specific quirks can be a real rabbit hole, especially when working with animated icons in a cross-platform app. Today, I’ve been troubleshooting an issue where on iOS, my animated icon not only appeared at an incorrect angle but also wasn’t spinning as it was supposed to. On Android, everything looked sleek and perfect.

First stop was tackling the size. Initially, removing the size and style properties from the parent component while the animated icon was wrapped in a tooltip didn’t give clarity, yet reinstating these properties aligned both iOS and Android unexpectedly. The clue came as I realized the style prop wasn’t simply decorative—it altered size properties under the hood, apparently caching states in unforeseen ways.

Having identified this dual-platform discord, I meticulously tested the effects of the style prop through a sequence of reloads, confirming the iOS differentiation in transforms and animations compared to Androids. A persistent non-rotation issue on iOS pointed fingers at the tooltip constraint, particularly when reintroducing the tooltip altered the icon’s size.

Next up was investigating tooltip behavior. Wrapping using React Native Elements UI revealed how its container style arbitrarily constrained icon sizes, a finding derived by experimenting with different versions of the tooltip. This realization has nudged my interest toward potentially customizing my tooltip due to the default UI’s arbitrary constraints.

The final step involved diving into the React Native Elements documentation and library, scrutinizing its approach to default props. Container styles proved impactful but not overly informative. Critical forethought revolved around how transform or scaling properties in the parent component could impose size constraints on children components, although suspected caching or memoization could also play roles.

At this juncture, rebuilding from a minimal use of external UI libraries to crafting or tweaking custom solutions seems viable—offering flexibilities lacking in monolithic third-party solutions.

So what’s next? Exploring alternative UI libraries or developing my own solution to address the quirks inherent in the iOS transformation will potentially eliminate reliance on under-maintained libraries, paving the way for a stable, intuitive user experience.
