Argument in message expression is an uninitialized value?

I get the warning Argument in message expression is an uninitialized value in the bolded line开发者_如何学Go below:

***SHKActionSheet *as = [[SHKActionSheet alloc] initWithTitle:SHKLocalizedString(@"Share")***
                                                      delegate:as
                                             cancelButtonTitle:nil
                                        destructiveButtonTitle:nil
                                             otherButtonTitles:nil];
    as.item = [[[SHKItem alloc] init] autorelease];
    as.item.shareType = type;

Any ideas whats wrong or how I can fix it? P.S - This is in ShareKit

Thanks!

Edit1: So you're saying to do this?

+ (SHKActionSheet *)actionSheetForType:(SHKShareType)type
{
    SHKItem *myItem = [SHKItem text:@"Share"];  // See SHKItem for other convenience constructors for URL, image, text and file item types.
    SHKActionSheet *as = [SHKActionSheet actionSheetForItem:myItem];
    as.item.shareType = type;

    as.sharers = [NSMutableArray arrayWithCapacity:0];
    NSArray *favoriteSharers = [SHK favoriteSharersForType:type];

    // Add buttons for each favorite sharer
    id class;
    for(NSString *sharerId in favoriteSharers)
    {
        class = NSClassFromString(sharerId);
        if ([class canShare])
        {
            [as addButtonWithTitle: [class sharerTitle] ];
            [as.sharers addObject:sharerId];
        }
    }

    // Add More button
    [as addButtonWithTitle:SHKLocalizedString(@"More...")];

    // Add Cancel button
    [as addButtonWithTitle:SHKLocalizedString(@"Cancel")];
    as.cancelButtonIndex = as.numberOfButtons -1;

    return [as autorelease];
}

Edit2:

+ (SHKActionSheet *)actionSheetForType:(SHKShareType)type
{

    SHKActionSheet *as = [[SHKActionSheet alloc] initWithTitle:SHKLocalizedString(@"Share")
                                                      delegate:nil
                                             cancelButtonTitle:nil
                                        destructiveButtonTitle:nil
                                             otherButtonTitles:nil];
    as.item = [[[SHKItem alloc] init] autorelease];
    as.delegate = self;


    as.item.shareType = type;

    as.sharers = [NSMutableArray arrayWithCapacity:0];
    NSArray *favoriteSharers = [SHK favoriteSharersForType:type];

    // Add buttons for each favorite sharer
    id class;
    for(NSString *sharerId in favoriteSharers)
    {
        class = NSClassFromString(sharerId);
        if ([class canShare])
        {
            [as addButtonWithTitle: [class sharerTitle] ];
            [as.sharers addObject:sharerId];
        }
    }

    // Add More button
    [as addButtonWithTitle:SHKLocalizedString(@"More...")];

    // Add Cancel button
    [as addButtonWithTitle:SHKLocalizedString(@"Cancel")];
    as.cancelButtonIndex = as.numberOfButtons -1;

    return [as autorelease];
}

I'm pretty sure the problem is on this line:

delegate:as

the problem is you are setting delegate to 'as' which is the name of the action sheet you are in the process of initialising. (so you are trying to pass a ref to an object you are in the process of initialising as an argument to its initialiser).

Instead set the delegate to nil on the alloc/init call and explicitly set the delegate after the call.

SHKActionSheet *as = [[SHKActionSheet alloc] initWithTitle:SHKLocalizedString(@"Share")***
                                    delegate:nil
                                    cancelButtonTitle:nil
                                    destructiveButtonTitle:nil
                                    otherButtonTitles:nil];
as.delegate = as;
as.item = [[[SHKItem alloc] init] autorelease];
as.item.shareType = type;
