Swift Xcode：在动态框架中使用自定义字体

我来晚了一点，但我接受了PetahChristian的解决方案，以扩展的形式创建了一个Swift版本.这对我有用.我发现，当你试图以常规方式使用字体名称和大小获取字体时，它总是在主Bundle 包中查找字体文件，并且没有方法将Bundle 包标识符作为参数.如果苹果能做一个就好了.

Swift:

public extension UIFont {

    public static func jbs_registerFont(withFilenameString filenameString: String, bundle: Bundle) {

        guard let pathForResourceString = bundle.path(forResource: filenameString, ofType: nil) else {
            print("UIFont+:  Failed to register font - path for resource not found.")
            return
        }

        guard let fontData = NSData(contentsOfFile: pathForResourceString) else {
            print("UIFont+:  Failed to register font - font data could not be loaded.")
            return
        }

        guard let dataProvider = CGDataProvider(data: fontData) else {
            print("UIFont+:  Failed to register font - data provider could not be loaded.")
            return
        }

        guard let font = CGFont(dataProvider) else {
            print("UIFont+:  Failed to register font - font could not be loaded.")
            return
        }

        var errorRef: Unmanaged<CFError>? = nil
        if (CTFontManagerRegisterGraphicsFont(font, &errorRef) == false) {
            print("UIFont+:  Failed to register font - register graphics font failed - this font may have already been registered in the main bundle.")
        }
    }

}

用法示例:

UIFont.jbs_registerFont(
    withFilenameString: "Boogaloo-Regular.ttf",
    bundle: Bundle(identifier: "com.JBS.JBSFramework")!
)
