Swift 2.0 裁剪字符串以及Int和String转化

swift 2.0

字符串裁剪:

let text = "1234567890" let t = text.startIndex.advancedBy(1)

text = text.substringFromIndex(t)//"234567890"

let t1 = text.endIndex.advancedBy(-1)

text = text.substringFromIndex(t)//"123456789"

Int To String:

let t = 12
let s = t.description//s="12"

String To Int

let s = "12"
let t = Int(s)//t=12
