一，效果圖。

二，程式碼。

RootViewController.h

#import <UIKit/UIKit.h>

@interface RootViewController : UIViewController
<UIActionSheetDelegate>

@end

RootViewController.m

//點選任何處，彈出UIActionSheet
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UIActionSheet *sheet=[[UIActionSheet alloc]initWithTitle:@"
 
標題" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];
    
    // 逐個新增按鈕（比如可以是陣列迴圈）
    [sheet addButtonWithTitle:@"Item A"];
    [sheet addButtonWithTitle:@"Item B"];
    [sheet addButtonWithTitle:@"Item C"];
    // 同時新增一個取消按鈕
    [sheet addButtonWithTitle:@"Cancel
 
"];
    
    sheet.cancelButtonIndex = sheet.numberOfButtons-1;
    [sheet showInView:self.view];

}
