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 @R_590_4045@ion.\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
