在Xcode日志中找不到字体SKLabelNode警告

Question

我正在使用精灵工具包在我的苹果手表中创建自定义视图.我已经为SKLabelNode添加了自定义字体.当我在我的设备中运行代码并观看时,该字体已应用并且也可以使用.但每次我都低于警告

SKLabelNode:找不到"SFCompactText-Regular"字体.

字体应用于标签并且工作完美且不会崩溃.为什么每次都会显示此警告？

以下是来自苹果手表输出的清单:

Answer 1

我通过以下步骤解决了我的问题:

- 在Watch Extension目标中添加了我的字体.

- 为WatchApp和WatchExtension增加了目标成员资格.

- 在WatchApp和WatchExtension info.plist文件中添加了字体输入.

- 使用下面的代码检查实际的字体名称.

for fontFamily in UIFont.familyNames {
        print("Font family name = \(fontFamily as String)")
        for fontName in UIFont.fontNames(forFamilyName: fontFamily as String) {
            print("- Font name = \(fontName)")
        }
}

- 为我的自定义字体处理了一个struct常量.

struct UIFontConst {
    static let SF_COMPACT_TEXT_REGULAR  = UIFont(name: "SFCompactText-Regular", size: 9.0)
}

- 并使用喜欢UIFontConst.SF_COMPACT_TEXT_REGULAR?.fontName.
