UIActionSheet

上拉菜单:基本常用方法与弹窗AlertView差不多

初始化

UIActionSheet  *actionSheet = [[UIActionSheet alloc] initWithTitle:@"确认删除?" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles: nil];

添加button

[actionSheet addButtonWithTitle:@"退出"];

更改标题

 actionSheet.title = @"是否退出";

显现下拉菜单

[actionSheet showInView:self.view];

ActionSheet也多与button连用

 UIButton *button = [UIButton buttonWithType:(UIButtonTypeCustom)];
    button.frame = CGRectMake(100, 100, 100, 100);
    button.backgroundColor = [UIColor redColor];
    [button setTitle:@"删除" forState:(UIControlStateNormal)];
    [button addTarget:self action:@selector(clickedButton:) forControlEvents:(UIControlEventTouchUpInside)];
    [self.view addSubview:button];

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

    UIActionSheet  *actionSheet = [[UIActionSheet alloc] initWithTitle:@"确认删除?" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles: nil];
    [actionSheet addButtonWithTitle:@"退出"];
    actionSheet.title = @"是否退出";
    [actionSheet showInView:self.view];
    [actionSheet release];

}

// 遵循 UIActionSheetDelegate协议
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    switch (buttonIndex) {
        case 0:
            // ********
            NSLog(@"ddd");
            break;
        case 1:
            NSLog(@"aaa");
            break;

        default:
            break;
    }
}
