UIActionSheet 使用

一、基本用法

UIActionSheet提供了从屏幕底部向上滚动的菜单，同UIAlertView一样，它也是一个模态对话框

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    [[self window] makeKeyAndVisible];

    

    

    UIActionSheet* alert = [[UIActionSheet alloc] initWithTitle:@"请选择您喜欢的颜色："

                                                      delegate:nil

                                             cancelButtonTitle:@"取消"

                                        destructiveButtonTitle:nil

                                             otherButtonTitles:@"红色",@"橙色",@"黄色",@"蓝色",@"紫色",@"白色",@"黑色",nil];

    [alert showInView:[self window]];

    [alert release];

    

    return YES;

}

二、获取点击了那一项（委托）

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    [[self window] makeKeyAndVisible];

    

    

    UIActionSheet* alert = [[UIActionSheet alloc] initWithTitle:@"请选择您喜欢的颜色："

                                                      delegate:self

                                             cancelButtonTitle:@"取消"

                                        destructiveButtonTitle:nil

                                             otherButtonTitles:@"红色",@"橙色",@"黄色",@"蓝色",@"紫色",@"白色",@"黑色",nil];

    [alert showInView:[self window]];

    [alert release];

    

    return YES;

}

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

{

    NSString *msg = [[NSString alloc] initWithFormat:@"你点击了第%d项",buttonIndex];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"通知" message:msg delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];

    [alert show];

    [alert release];

}
