<code>typedef</code> <code>ns_enum(nsinteger, uiactionsheetstyle) {</code>

<code>    </code><code>uiactionsheetstyleautomatic        = -1,      </code>

<code>    </code><code>uiactionsheetstyledefault          = uibarstyledefault,</code>

<code>    </code><code>uiactionsheetstyleblacktranslucent = uibarstyleblacktranslucent,</code>

<code>    </code><code>uiactionsheetstyleblackopaque      = uibarstyleblackopaque,</code>

<code>};</code>

- (nsinteger)addbuttonwithtitle:(nsstring *)title;

添加一个按钮，会返回按钮的索引

- (nsstring *)buttontitleatindex:(nsinteger)buttonindex;

获取按钮标题

@property(nonatomic,readonly) nsinteger numberofbuttons;

获取按钮数量

@property(nonatomic) nsinteger cancelbuttonindex;

设置取消按钮的索引值

@property(nonatomic) nsinteger destructivebuttonindex;

设置特殊标记

@property(nonatomic,readonly,getter=isvisible) bool visible;

视图当前是否可见

下面是几种弹出方式，会根据风格不同展现不同的方式

- (void)showfromtoolbar:(uitoolbar *)view;

- (void)showfromtabbar:(uitabbar *)view;

- (void)showfrombarbuttonitem:(uibarbuttonitem *)item animated:(bool)animated ;

- (void)showfromrect:(cgrect)rect inview:(uiview *)view animated:(bool)animated ;

- (void)showinview:(uiview *)view;

- (void)dismisswithclickedbuttonindex:(nsinteger)buttonindex animated:(bool)animated;

使用代码将视图收回

- (void)actionsheet:(uiactionsheet *)actionsheet clickedbuttonatindex:(nsinteger)buttonindex;

点击按钮时触发的方法

- (void)willpresentactionsheet:(uiactionsheet *)actionsheet; 

视图将要弹出时触发的方法

- (void)didpresentactionsheet:(uiactionsheet *)actionsheet;

视图已经弹出式触发的方法

- (void)actionsheet:(uiactionsheet *)actionsheet willdismisswithbuttonindex:(nsinteger)buttonindex;

点击按钮后，视图将要收回时触发的方法

- (void)actionsheet:(uiactionsheet *)actionsheet diddismisswithbuttonindex:(nsinteger)buttonindex;

点击按钮后，视图已经收回时触发的方法
