if let navigationBar = imageEditor.navigationBar {
    if let rightBarButtonItem = navigationBar.topItem?.rightBarButtonItem {
        // 在这里进行文本颜色的更改
    }
}

if let navigationBar = imageEditor.navigationBar {
    if let rightBarButtonItem = navigationBar.topItem?.rightBarButtonItem {
        let attributes: [NSAttributedString.Key: Any] = [
            .foregroundColor: UIColor.red // 设置为红色
        ]
        let attributedTitle = NSAttributedString(string: "按钮文本", attributes: attributes)
        rightBarButtonItem.title = nil // 清空原有文本
        rightBarButtonItem.setAttributedTitle(attributedTitle, for: .normal)
    }
}
