Swift属于左侧预期编号列表

我使用下面的代码在警报样式UIAlertController中创建规则列表

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.Left
let messageText = NSMutableAttributedString(
    string: "1. Do not bully or target other users.\n2. Do not post others' private information.\n3. Do not post useless or offensive content.\n4. Do not post others' copyrighted content.\n5. DownVote and Flag posts which violate these rules.\n6. If you violate these rules,your account may be suspended and/or your content removed.",attributes: [
        NSParagraphStyleAttributeName: paragraphStyle,NSFontAttributeName : UIFont(name: "Lato-Regular",size: 13.0)!,NSForegroundColorAttributeName : colorAccentWords
    ]
)

它给了我警报视图,如下所示：

我想要的是使编号列表保持预期,以便每行的溢出文本将保持对齐.我怎样才能做到这一点？

解决方法

例如,将paragraphStyle的headindent属性设置为适当的值

paragraphStyle.headindent = 13.0
