A-ViewContainer 是多控件的卡片容器。
使用：
// If the view is A_MultipleViewContainer already, then you don't need to call InstallTo method.A_MultipleViewContainer *centerView = [A_MultipleViewContainer A_InstallTo:self.view]; [centerView A_AddChild:[DemoLabelViewController createWithNumber:0]]; [centerView A_AddChild:[DemoLabelViewController createWithNumber:1]]; [centerView A_AddChild:[DemoLabelViewController createWithNumber:2]]; [centerView A_AddChild:[DemoLabelViewController createWithNumber:3]]; [centerView A_Display];
