Swift小功能点积累

let label = UILabel(frame: CGRectMake(100, 100, 0, 0))
let attr = NSMutableAttributedString(string: "123")
attr.addAttribute(NSStrikethroughStyleAttributeName, value: NSNumber(integer: 1), range: NSMakeRange(0, 3))
label.attributedText = attr
label.sizeToFit()

self.view.addSubview(label)

var date = NSDate()
var timeFormatter = NSDateFormatter()
timeFormatter.dateFormat = "yyy-MM-dd 'at' HH:mm:ss.SSS" (格式可俺按自己需求修整)
var strNowTime = timeFormatter.stringFromDate(date) as String
