将带空格的字符串拆分为带换行符的字符串并显示在UILabel中

Question

I want to take a string I have ie "English Language" and create a string that will display each word on a separate line. Currently I have:

    let subjectDesc = "English Language"
    let splitArray = subjectDesc?.componentsSeparatedByString(" ")

    var finalString = ""
    for item in splitArray! {
        finalString = finalString + item + "\n"
    }
    print("The final string is \(finalString)")
    cell.subjectLabel.text = finalString

I have the UILabel Line Breaks mode set to Word Wrap on 2 lines. The label is only displaying the first word. What am I doing wrong here?

Any pointers would be really appreciated! Thanks

您应该将UILabel的numberOfLines设置为0以显示多行。
