IOS中UIActionSheet使用詳解

IOS中UIActionSheet使用方法詳解

1、初始化方法

- (instancetype)initWithTitle:(NSString *)title delegate:(id<UIActionSheetDelegate>)delegate cancelButtonTitle:(NSString *)cancelButtonTitle destructiveButtonTitle:(NSString *)destructiveButtonTitle otherButtonTitles:(NSString *)otherButtonTitles, ...;atom

 

參數說明:spa

title:視圖標題.net

delegate:設置代理3d

cancelButtonTitle:取消按鈕的標題代理

destructiveButtonTitle:特殊標記的按鈕的標題code

otherButtonTitles:其餘按鈕的標題索引

2、經常使用方法和屬性介紹

 

@property(nonatomic,copy) NSString *title;get

設置標題it

 

@property(nonatomic) UIActionSheetStyle actionSheetStyle;io

設置風格,枚舉以下:

typedef NS_ENUM(NSInteger, UIActionSheetStyle) {
    UIActionSheetStyleAutomatic        = -1,      
    UIActionSheetStyleDefault          = UIBarStyleDefault,
    UIActionSheetStyleBlackTranslucent = UIBarStyleBlackTranslucent,
    UIActionSheetStyleBlackOpaque      = UIBarStyleBlackOpaque,
};

 

- (NSInteger)addButtonWithTitle:(NSString *)title;

添加一個按鈕,會返回按鈕的索引

 

- (NSString *)buttonTitleAtIndex:(NSInteger)buttonIndex;

獲取按鈕標題

 

@property(nonatomic,readonly) NSInteger numberOfButtons;

獲取按鈕數量

@property(nonatomic) NSInteger cancelButtonIndex;

設置取消按鈕的索引值

 

@property(nonatomic) NSInteger destructiveButtonIndex;

設置特殊標記

 

@property(nonatomic,readonly,getter=isVisible) BOOL visible;

視圖當前是否可見

 

下面是幾種彈出方式,會根據風格不一樣展示不一樣的方式

- (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

3、UIActionSheet代理方法

 

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex;

點擊按鈕時觸發的方法

 

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet; 

視圖將要彈出時觸發的方法

 

- (void)didPresentActionSheet:(UIActionSheet *)actionSheet;

視圖已經彈出式觸發的方法

 

- (void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex;

點擊按鈕後,視圖將要收回時觸發的方法

 

- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex;

點擊按鈕後,視圖已經收回時觸發的方法
