本文介绍了如何在 iOS 开发中使用 UITableView 进行自定义选中效果、背景颜色设置及添加图片背景的方法。此外还提供了生成随机数的示例代码，并探讨了 UIView 动画过渡效果以及 CALayer 的 Action 执行机制。

TableViewController:

1 disable selected: willSelectedRowAtIndex:(NSIndexPath *)index{ return nil; }
   2 TableView can custom it's title foot
   3 Adding float title effect: titleForHeaderInSection:(NSInteger)section{return "ss"};

Favoriate background color
   [UIColor colorWithRed:197.0/255.0 green:204.0/255.0 blue:211.0/255.0 alpha:1.0];

Generate random number

// Get random number between 0 and 500
int x = arc4random ( ) % 100 ;
// Get random number between 500 and 1000
int y = ( arc4random ( ) % 501 ) + 500 ) ;
//Get random number among a specify number
(rand()%6)+1

View animation transation:
UIViewAnimationTransitionNone, UIViewAnimationTransitionFlipFromLeft, UIViewAnimationTransitionFlipFromRight UIViewAnimationTransitionCurlU, UIViewAnimationTransitionCurlDown

Animation Transaction: animation同样支持事务，让一群Animation一起提交

Action:
   一个Layer管理很多Action,每个Action有一个key layer.actions=actions(NSMutableDirectory)
   Layer执行Action: actionForLayer:forKey.方法
   Layer在几种情况下会触发Action, 1 被插入一个Layer-Tree, 2被remove一个Layer-Tree 3被replace一个Layer
每个CAAction实现runActionForKey方法，在其中定义Animation, 可以实现actionForKey返回一个CAAnimation来指定默认的implite animation

Add Image for view background

UIView doesn't support add image to background. The solution is add an ImageView to surface of UIView. And allow user can interaction with its subviews

[imageView setUserInteractionEnabled:YES]
