UIAlertView和UIActionSheet相似,区别很小, 很容易理解。

- (void)viewDidLoad {

    [super viewDidLoad];

    

    //设置Frame无效

    _actionSheet=[[UIActionSheet alloc]initWithFrame:CGRectMake(20, 20, 200, 100)];

    [_actionSheet addButtonWithTitle:@"相册"];

    [_actionSheet addButtonWithTitle:@"相机"];

    [_actionSheet addButtonWithTitle:@"取消"];

    _actionSheet.cancelButtonIndex=2;

    _actionSheet.destructiveButtonIndex=1;

    _actionSheet.title=@"提示";

    

    _actionSheet.delegate=self;

//    typedef NS_ENUM(NSInteger, UIActionSheetStyle) {

//        UIActionSheetStyleAutomatic        = -1,       // take appearance from toolbar style otherwise uses 'default'

//        UIActionSheetStyleDefault          = UIBarStyleDefault,

//        UIActionSheetStyleBlackTranslucent = UIBarStyleBlackTranslucent,

//        UIActionSheetStyleBlackOpaque      = UIBarStyleBlackOpaque,

//    };

    _actionSheet.actionSheetStyle=UIActionSheetStyleBlackOpaque;

    _actionSheet.tag=10001;

    

    NSLog(@"firstOtherButtonIndex=%ld",_actionSheet.firstOtherButtonIndex);

    for (int i=0; i<_actionSheet.numberOfButtons; i++) {

        NSLog(@"i=%d %@",i,[_actionSheet buttonTitleAtIndex:i]);

    }

    [_actionSheet showInView:self.view];

    

    _actionSheet1 =[[UIActionSheet alloc]initWithTitle:@"提示" delegate:self cancelButtonTitle:@"NO" destructiveButtonTitle:@"DestructiveButton" otherButtonTitles:@"YES", nil];

    _actionSheet1.tag=10002;

    for (int i=0; i<_actionSheet1.numberOfButtons; i++) {

        NSLog(@"i=%d %@",i,[_actionSheet1 buttonTitleAtIndex:i]);

    }

    [_actionSheet1 showInView:self.view];

    

}

//UIActionSheetDelegate

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

{

    if (actionSheet.tag==10001) {

        NSString *title=[_actionSheet buttonTitleAtIndex:buttonIndex];

        NSLog(@"我点击了: %@",title);

    }

    else

    {

        if (buttonIndex==2) {

            [_actionSheet dismissWithClickedButtonIndex:2 animated:YES];

        }

    }

}



//以下这些和UIAlertView的相似

- (void)actionSheetCancel:(UIActionSheet *)actionSheet

{

    NSLog(@"actionSheetCancel");

}



- (void)willPresentActionSheet:(UIActionSheet *)actionSheet

{

    NSLog(@"willPresentActionSheet");

}

- (void)didPresentActionSheet:(UIActionSheet *)actionSheet

{

    NSLog(@"didPresentActionSheet");

}



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

{

    NSLog(@"willDismissWithButtonIndex");

}

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

{

    NSLog(@"didDismissWithButtonIndex");

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}
