注意点:控制器之间的跳转(navigation)，数据本地存储，控制器之前传递数据
首先是数据模型，主要注意遵循了NSCoding协议和实现了协议的方法，这样对象才能存储

import UIKit
// 遵循了NSCoding协议
class Address: NSObject,NSCoding {
var name:NSString!
var address:NSString!
// 构造方法
init(name:NSString,address:NSString) {
self.name = name
self.address = address
}
// NSCoding协议构造方法
required init?(coder aDecoder: NSCoder) {
self.name = aDecoder.decodeObjectForKey("name") as! NSString
self.address = aDecoder.decodeObjectForKey("address") as! NSString
}
// NSCoding协议解码方法
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(self.name, forKey: "name")
aCoder.encodeObject(self.name, forKey: "address")
}
// 写文件类方法,其实开始我是打算用 NSMutableData的方法来存储的，用NSMutableData的话，在读取的时候会有点麻烦
class func writeAddresses(addresses:[Address])
{
NSKeyedArchiver.archiveRootObject(addresses, toFile: addressesPath)
}
// 对文件类方法
class func readeAddresses()->[Address]
{
let mutableData = NSKeyedUnarchiver.unarchiveObjectWithFile(addressesPath)
if mutableData == nil
{
return []
}
else
{
return mutableData as! [Address]
}
}
}
两个路径配置
import Foundation
// 用户信息存放路径
let userInfoPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true).last! + "/userInfo.plist"
let addressesPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true).last! + "/addresses.plist"
