IOS中UIActionSheet使用方法详解
一、初始化方法
- (instancetype)initWithTitle:(NSString?*)title delegate:(id<UIActionSheetDelegate>)delegate cancelButtonTitle:(NSString?*)cancelButtonTitle destructiveButtonTitle:(NSString?*)destructiveButtonTitle otherButtonTitles:(NSString?*)otherButtonTitles, ...;
?
參數(shù)說明:
title:視圖標(biāo)題
delegate:設(shè)置代理
cancelButtonTitle:取消按鈕的標(biāo)題
destructiveButtonTitle:特殊標(biāo)記的按鈕的標(biāo)題
otherButtonTitles:其他按鈕的標(biāo)題
二、常用方法和屬性介紹
?
@property(nonatomic,copy)?NSString?*title;
設(shè)置標(biāo)題
?
@property(nonatomic)?UIActionSheetStyle?actionSheetStyle;
設(shè)置風(fēng)格,枚舉如下:
?| 1 2 3 4 5 6 | typedef?NS_ENUM(NSInteger,?UIActionSheetStyle)?{ ????UIActionSheetStyleAutomatic????????=?-1,?????? ????UIActionSheetStyleDefault??????????=?UIBarStyleDefault, ????UIActionSheetStyleBlackTranslucent?=?UIBarStyleBlackTranslucent, ????UIActionSheetStyleBlackOpaque??????=?UIBarStyleBlackOpaque, }; |
?
- (NSInteger)addButtonWithTitle:(NSString?*)title;
添加一個(gè)按鈕,會(huì)返回按鈕的索引
?
- (NSString?*)buttonTitleAtIndex:(NSInteger)buttonIndex;
獲取按鈕標(biāo)題
?
@property(nonatomic,readonly)?NSInteger?numberOfButtons;
獲取按鈕數(shù)量
@property(nonatomic)?NSInteger?cancelButtonIndex;
設(shè)置取消按鈕的索引值
?
@property(nonatomic)?NSInteger?destructiveButtonIndex;
設(shè)置特殊標(biāo)記
?
@property(nonatomic,readonly,getter=isVisible)?BOOL?visible;
視圖當(dāng)前是否可見
?
下面是幾種彈出方式,會(huì)根據(jù)風(fēng)格不同展現(xiàn)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;
使用代碼將視圖收回
三、UIActionSheet代理方法
?
- (void)actionSheet:(UIActionSheet?*)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex;
點(diǎn)擊按鈕時(shí)觸發(fā)的方法
?
- (void)willPresentActionSheet:(UIActionSheet?*)actionSheet;?
視圖將要彈出時(shí)觸發(fā)的方法
?
- (void)didPresentActionSheet:(UIActionSheet?*)actionSheet;
視圖已經(jīng)彈出式觸發(fā)的方法
?
- (void)actionSheet:(UIActionSheet?*)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex;
點(diǎn)擊按鈕后,視圖將要收回時(shí)觸發(fā)的方法
?
- (void)actionSheet:(UIActionSheet?*)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex;
點(diǎn)擊按鈕后,視圖已經(jīng)收回時(shí)觸發(fā)的方法
