let age = now! - year!
let hasPropertyText = hasProperty.on ? "有房" : "無房"
result.text = "\(name.text), \(age)歲，\(genderText),身高\(height.text!),\(hasPropertyText)"
let hasPropertyText = hasProperty.on ? "有房" : "無房"
result.text = "\(name.text), \(age)歲，\(genderText),身高\(height.text!),\(hasPropertyText)"

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy"
let year = dateFormatter.stringFromDate(birthday.date).toInt()
let now = dateFormatter.stringFromDate(NSDate()).toInt()
dateFormatter.dateFormat = "yyyy"
let year = dateFormatter.stringFromDate(birthday.date).toInt()
let now = dateFormatter.stringFromDate(NSDate()).toInt()
