Using iconFont for iOS App Icon Replacement: A Step‑by‑Step Guide

iconFont is a vector icon library offered by Alibaba that converts icons into a font, allowing them to be displayed as text on Web, iOS, and Android platforms.

Step 1 – Obtain the icons: Log in to the iconFont website, choose a consistent set of icons, add them to the cart, and download the package, which includes demo_index.html and iconFont.ttf .

Step 2 – Import into an iOS project: Unzip the package, locate the iconFont.ttf file and add it to the Xcode project. Register the font name in Info.plist . Then use the font in code. Example Swift usage: label.font = UIFont(name: "iconFont", size: 26.0) label.text = "\u{e658}" Example Objective‑C usage: label.font = [UIFont fontWithName:@"iconFont" size:34]; label.text = @"\U0000e658"

Step 3 – Preview the icons: Open demo_index.html to see the Unicode mapping of each icon and apply the corresponding Unicode value in the app.

Step 4 – Common issues and solutions: Multiple .ttf files with the same font name can cause conflicts; rename fonts with a tool before importing. Different download accounts may generate different Unicode values, leading to mismatched icons. The iconFont library is not free for commercial use unless a special license is obtained, so use it only for personal or non‑commercial projects.
