[待解决问题]
我在uiviewcontroller的view中加入了一个uitableview用于显示数据，是异步加载的形式，数据从web服务器接口获得。就是代码里的userlistview,就是为什么这里必须要设置self.userListView.frame=self.view.bounds;这样一句代码，userListView 的delegate和datasource对应的协议方法才会被调用呢？ 而且就算是 设置self.userList.frame=CGRectMake(<#CGFloat x#>, <#CGFloat y#>, <#CGFloat width#>, <#CGFloat height#>)这样都不行，必须要用上面那一句。 还有就是我自定义uitableviewcell中需要显示图片，我想问下这种需要大量显示图片的情况是怎样处理的呢？ 因为我的程序加载tableview的时候会感觉卡卡的。还有就是我的tableview在向上拉时始终拖动不到view的最后一个cell，向上拉一截，一松手又退下去了，不知道这种现象时怎么回事？ 麻烦懂的帮忙解答一下，感激不尽。我把程序压锁了发到百度网盘里的，http://pan.baidu.com/s/1i3BlEPf
