func GetTimeStamp() -> String {
    // 获取当前时间
    let now = NSDate()
    // 当前时间的时间戳
    let timeInterval: TimeInterval = now.timeIntervalSince1970
    let timeStamp = Int(timeInterval)
    
    return "\(timeStamp)"

    //获取当前时间
    let now = NSDate()
    //当前时间的时间戳
    let timeInterval : TimeInterval = now.timeIntervalSince1970
