我感覺UIActionSheet和UIAlertView的用法差不多，都很簡單，下面給出一個簡單的Demo，具體想用哪個，根據公司要求和個人愛好。

?

#import "ViewController.h"

@interface ViewController ()<UIActionSheetDelegate>

@end

@implementation ViewController

?

- (void)viewDidLoad {

? ? [super viewDidLoad];

? ? UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];

? ? button.frame = CGRectMake(100, 100, 100, 40);

? ? button.backgroundColor = [UIColor orangeColor];

? ? [button setTitle:@"彈出操作表" forState:UIControlStateNormal];

? ? [button addTarget:self action:@selector(showActionSheet:)?forControlEvents:UIControlEventTouchUpInside];

? ? [self.view addSubview:button];

}

?

- (void)showActionSheet:(UIButton*)button {

　　//destructiveButton是紅色按鈕，是ActionSheet支持的一種所謂的銷毀按鈕，對用戶的某種行為起到警示作用，比如修改、刪除某個東西
　　//destructiveButton,1,2,3,Cancel，它們的buttonIndex分別為0，1，2，3，4

? ? UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"呵呵" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"destructiveButton" otherButtonTitles:@"1",@"2",@"3", nil];

? ? [actionSheet showInView:self.view];

}

?

// Called when a button is clicked. The view will be automatically dismissed after this call returns

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

? ? if (0 == buttonIndex) {

? ? ? ? NSLog(@"0");

? ? } else if (1 == buttonIndex) {

? ? ? ? NSLog(@"1");

? ? } else if (2 == buttonIndex) {

? ? ? ? NSLog(@"2");

? ? } else if (3 == buttonIndex) {

? ? ? ? NSLog(@"3");

? ? } else {

? ? ? ? NSLog(@"4");

? ? }

}

??

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

? ? NSLog(@"willPresentActionSheet");

}// before animation and showing view

?

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

? ? NSLog(@"didPresentActionSheet");

}// after animation

?

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

? ? NSLog(@"willDismissWithButtonIndex");

}// before animation and hiding view

?

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

? ? NSLog(@"didDismissWithButtonIndex");

}// after animation

@end

?
