看似簡單的下拉魔种，上拉，其實還蠻復雜的，值得好好研究！

寫在貼代碼之前荷荤，首先得思考幾個問題:
1、下拉時得查找服務器上最新的數(shù)據 然后填充Model
2梭稚、再次下拉時，查找服務器上是否再有新的數(shù)據了，有的話再把新的加在數(shù)組在前面
3伸辟、不要每次下拉都清空Model，再把下拉的數(shù)據都填充到Model恰梢，試想想埂陆，如果用戶本來已經上拉了500條數(shù)據在手機里，你再一下拉蓬抄，豈不是把用戶本機上的都清空了胆敞？（一定要和后臺配合好秦叛，通過MaxID值或者其它值來判斷）
4膨报、上拉時饮怯，相對簡單點闰靴，有新的數(shù)據识埋，就直接把新的數(shù)據加在數(shù)組的后面就行了，沒有的話蛹疯，就提示用戶沒有再多數(shù)據就可以了。

話嘮嗑多了，直接上代碼了邻吭，MVVC+服務器后端JSON 共5個文件!
