我试图通过仅构建一个可重复使用的XIB而不是构建三个视图以放入stackView来使生活更轻松

我已经创建了自定义的xib文件，并将其连接到自己的自定义类：

标签和图像受约束放置。我希望标签能够自动调整大小，最多三行，因此标签的高度限制为> =，内容视图也可以按高度缩放（> =）

UserReview代码：

class UserReview: UIView {

@IBOutlet weak var userImage: UIImageView!
@IBOutlet weak var username: UILabel!
@IBOutlet weak var userRating: UILabel!
@IBOutlet weak var reviewText: UILabel!
@IBOutlet weak var prosText: UILabel!
@IBOutlet weak var consText: UILabel!

class func instanceFromNib() -> UIView {
    return UINib(nibName: "UserReview", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}

func setUp(review: Review){
        // TODO set userImage
        username.text = review.username!
        // TODO add rating + color
        reviewText.text = review.content!
        if let pros = …

我的应用程序崩溃了，这是调用堆栈：

我不知道如何复制这个崩溃，你有什么想法会导致这样的崩溃吗？

嗨我想从列表中删除所有m的倍数(例如[2..100])

我的代码:

crossOut :: Int -> [Int] -> [Int]
crossOut n ns = [ x | x <- ns , x /= (n*x)]
