ios - 将字符串数组显示为多行字符串 - Swift

Question

我有一个字符串数组，我需要将其转换为多行的单个字符串

 var array = ["A","B","C","D","E"]
 var multiLineString = //convert array to a string
 println("\(multiLineString)")

输出应该是:

  A 
  B 
  C 
  D 
  E 

Answer 1

应该是这样的:

var array = ["A","B","C","D","E"]
var multiLineString = join("\n", array)
println("\(multiLineString)")

请注意，控制台不会打印多行。

更新:要获取标签的高度以显示此字符串:

let label = UILabel()
label.text = multiLineString
label.numberOfLines = 0
label.lineBreakMode = NSLineBreakMode.ByWordWrapping
label.sizeToFit()
println("Height: \(label.frame.height)")
