#pragma mark - show  UIActionSheetDelegate-(IBAction)shows:(id)sender{    UIActionSheet *alert = [[UIActionSheet alloc]initWithTitle:@"title" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"这是哪个button" otherButtonTitles:@"other1",@"other2", nil];        [alert showInView:self.view];}#pragma mark - UIActionSheetDelegate- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{    //获得当前索引按钮的标题    NSString *title = [actionSheet buttonTitleAtIndex:buttonIndex];    NSLog(@"%@",title);}

ios8.0 之后，用这个替换

#pragma mark - show-(IBAction)shows:(id)sender{//    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"My Title" message:@"show to you" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",@"Other", nil];//    [alert show];        UIAlertController* alert = [UIAlertController alertControllerWithTitle:nil  //nil  这一项就会隐藏                                                                   message:@"This is an alert." //nil  这一项就会隐藏                                                            preferredStyle:UIAlertControllerStyleAlert];//    typedef enum UIAlertControllerStyle: NSInteger {//        UIAlertControllerStyleActionSheet = 0, //底端出现的  就是 UiActionSheet//        UIAlertControllerStyleAlert            //对话框//    } UIAlertControllerStyle;        UIAlertAction* OKAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault                                    handler:^(UIAlertAction * action) {                                        NSLog(@"%@",action.title);                                    }];    UIAlertAction* CancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault                                                          handler:^(UIAlertAction * action) {                                                               NSLog(@"%@",action.title);                                                          }];    //addAction  添加    [alert addAction:OKAction];    [alert addAction:CancelAction];    [self presentViewController:alert animated:YES completion:nil];}
