IOS超强表格控件GMGridView
iOS为我们提供UITableView类，实现了项目的纵向排列，而对于iOS整个操作桌面，所有应用程序却是以网格的形式排列，Gulam Moledina帮我们实现了这个效果，而且留有的接口与UITableView类似，使用起来相当方便。
需要的环境支持：
1、iOS5，需要UIScrollView手势支持；
2、ARC(Automatic Reference Counting自动引用计数)
3、框架Frameworks: Foundation, UIKit, CoreGraphics and QuartzCore
简单解析：
属性：
layoutStrategy和style属性，用来设置显示样式。
editing属性，是否进入编辑状态。
minEdgeInsets属性设置项目与项目直接的间隔。
代理dataSource，actionDelegate，sortingDelegate，transformDelegate接收数据或是处理事件。
代理：
GMGridViewDataSource项目的多少以及样子（cell）
GMGridViewActionDelegate重点捕获了，项目被点击的事件
GMGridViewSortingDelegate项目重排时一系列事件
GMGridViewTransformationDelegate项目状态改变时的变化
方法：
- (void)reloadData;//最常用的重新加载数据
- (void)insertObjectAtIndex:(NSInteger)index animated:(BOOL)animated;//插入
- (void)removeObjectAtIndex:(NSInteger)index animated:(BOOL)animated;//移除
- (void)reloadObjectAtIndex:(NSInteger)index animated:(BOOL)animated;//重载
- (void)swapObjectAtIndex:(NSInteger)index1 withObjectAtIndex:(NSInteger)index2 animated:(BOOL)animated;//排序项目
