ios – UILabel截断尾部并跳过不完整的单词

self.nameLabel.lineBreakmode = NSLineBreakByTruncaTingTail;

解决方法@H_419_31@

你可以这样做：

let labelWidth = CGRectGetWidth(label.bounds)

    let str = "you will have 30 seconds till you give us a good impression" as NSString
    let words = str.componentsSeparatedByString(" ")

    var newStr = "" as NSString

    for word in words{

        let statement = "\(newStr) \(word) ..." as NSString
        let size = statement.sizeWithAttributes([NSFontAttributename:label.font])
        if size.width < labelWidth {
            newStr = "\(newStr) \(word)"
        }
        else{
           break
        }
    }

    newStr = newStr.StringByAppendingString(" ...")

    self.label.text = newStr as String

想法是：我们分开单词并尝试检查宽度,同时从头开始追加字符串“…”直到我们找到一个超过大小的单词,在我们停止并使用这个新字符串的情况下
