UIScrollView && UITableView相关属性汇总及常用方法

属性：

UITableViewDatasource：实例化表视图时，必须采用该方法来实现数据源的配置
UITableViewDelegate：表视图的委托方法，一般用于处理表视图的基本样式以及捕捉选中单元格选中事件

1. UIScrollView：

tracking //当 touch 后还没有拖动的时候值是YES，否则NO

zoomBouncing //当内容放大到最大或者最小的时候值是 YES，否则 NO

zooming //当正在缩放的时候值是 YES，否则 NO

decelerating //当滚动后，手指放开但是还在继续滚动中。这个时候是 YES，其它时候是 NO

decelerationRate //设置手指放开后的减速率

maximumZoomScale //一个浮点数，表示能放最大的倍数

minimumZoomScale //一个浮点数，表示能缩最小的倍数

pagingEnabled //当值是 YES 会自动滚动到 subview 的边界。默认是NO

scrollEnabled //决定是否可以滚动

sView.contentSize = CGSizeMake(320*5,372);//滚动的范围

delaysContentTouches //是个布尔值，当值是 YES 的时候，用户触碰开始，scroll view要延迟一会，看看是否用户有意图滚动。假如滚动了，那么捕捉 touch-down 事件，否则就不捕捉。假如值是NO，当用户触碰， scroll view 会立即触发 touchesShouldBegin:withEvent:inContentView:，默认是 YES

canCancelContentTouches //当值是 YES 的时候，用户触碰后，然后在一定时间内没有移动，scrollView 发送 tracking events，然后用户移动手指足够长度触发滚动事件，这个时候，scrollView 发送了 touchesCancelled:withEvent: 到 subview，然后 scroView 开始滚动。假如值是 NO，scrollView 发送 tracking events 后，就算用户移动手指，scrollView 也不会滚动。

contentSize //里面内容的大小，也就是可以滚动的大小，默认是0，没有滚动效果。

showsHorizontalScrollIndicator //滚动时是否显示水平滚动条

showsVerticalScrollIndicator //滚动时是否显示垂直滚动条

bounces //默认是 yes，就是滚动超过边界会反弹有反弹回来的效果。假如是 NO，那么滚动到达边界会立刻停止。

bouncesZoom //和 bounces 类似,区别在于：这个效果反映在缩放上面，假如缩放超过最大缩放，那么会反弹效果；假如是 NO，则到达最大或者最小的时候立即停止。

directionalLockEnabled //默认是 NO，可以在垂直和水平方向同时运动。当值是 YES 时，假如一开始是垂直或者是水平运动，那么接下来会锁定另外一个方向的滚动。 假如一开始是对角方向滚动，则不会禁止某个方向

indicatorStyle //滚动条的样式，基本只是设置颜色。总共3个颜色：默认、黑、白

scrollIndicatorInsets //设置滚动条的位置

2，UITableView

tableView.bounces=NO//禁止拖动

tableView.separatorStyle = UITableViewCellSeparatorStyleNone;//去掉边框

[cellView setSelectionStyle:UITableViewCellSelectionStyleNone];//禁止触发点击某行//实现某行的选中效果（点击某行变颜色，松开还是刚变的颜色，点击其他行这行颜色消失）：[cellView setBackgroundColor:[UIColor clearColor]]; 

cellView.selectedBackgroundView = [[[UIView alloc] initWithFrame:cellView.frame] autorelease]; 

UIImageView *ia1=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 280, 170)];

 ia1.image=[UIImage imageNamed:@"ts_bg01.png"];

cellView.backgroundView=ia1;

UIImageView *ia2=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 280, 170)]; 

ia2.image=[UIImage imageNamed:@"ts_bg02.png"]; 

cellView.selectedBackgroundView=ia2;

方法：

//tableView的样式设置

typedef NS_ENUM(NSInteger, UITableViewStyle) {

    UITableViewStylePlain,              //无分区样式  

    UITableViewStyleGrouped             //多分区样式

};

//tableView滚动时，要滚动到的位置

typedef NS_ENUM(NSInteger, UITableViewScrollPosition) {

    UITableViewScrollPositionNone,

    UITableViewScrollPositionTop,    

    UITableViewScrollPositionMiddle,   

    UITableViewScrollPositionBottom

};

//tableView的cell操作时的动画效果

typedef NS_ENUM(NSInteger, UITableViewRowAnimation) {

    UITableViewRowAnimationFade,    //淡入或淡出

    UITableViewRowAnimationRight,           //从右边滑入或滑出

    UITableViewRowAnimationLeft,    //从左边滑入或滑出

    UITableViewRowAnimationTop,    //从顶部滑入或滑出

    UITableViewRowAnimationBottom,    //从底部滑入或滑出

    UITableViewRowAnimationNone,            // 无动画效果

    UITableViewRowAnimationMiddle,          //保持cell的中心在中部

    UITableViewRowAnimationAutomatic = 100  //自动适配动画

};

//sectionIndexTitlesForTableView: 返回的字符数组中包含了此字符串 具有放大图标展示的效果

 此字符串只能用于第一标题

UIKIT_EXTERN NSString *const UITableViewIndexSearch

//如果从tableView:titleForHeaderInSection: or tableView:titleForFooterInSection: 返回的标题不为空   那么从 tableView:heightForHeaderInSection: or tableView:heightForFooterInSection: 返回的值将对有标题的cell或section的高度有制约
