I am using this (http://stackoverflow.com/questions/6285210/uiactionsheet-for-deleting-a-uitableview-cell-on-cancel-keeps-showing-pressed-de) as a bit of a blueprint for setting up a block based action sheet. My actions for the action sheet are Cancel, Download, and Stream. I changed the BlockBasedActionSheet.h to:
@interface BlockBasedActionSheet : UIActionSheet<UIActionSheetDelegate> {
}

@property (copy) void (^cancelBlock)();
@property (copy) void (^downloadBlock)();
@property (copy) void (^streamBlock)();


- (id)initWithTitle:(NSString *)title cancelButtonTitle:(NSString *)cancelButtonTitle downloadButtonTitle:(NSString *)downloadButtonTitle streamButtonTitle:(NSString *)streamButtonTitle cancelAction:(void (^)())cancelBlock downloadAction:(void (^)())downloadBlock streamAction:(void (^)())streamBlock;

@end

and the BlockBasedActionSheet.m to:
@implementation BlockBasedActionSheet
@synthesize cancelBlock = _cancelBlock, streamBlock = _streamBlock, downloadBlock = _downloadBlock;

- (id)initWithTitle:(NSString *)title cancelButtonTitle:(NSString *)cancelButtonTitle downloadButtonTitle:(NSString *)downloadButtonTitle streamButtonTitle:(NSString *)streamButtonTitle cancelAction:(void (^)())cancelBlock downloadAction:(void (^)())downloadBlock streamAction:(void (^)())streamBlock
{
self = [super initWithTitle:title delegate:self cancelButtonTitle:cancelButtonTitle destructiveButtonTitle:nil otherButtonTitles:downloadButtonTitle, streamButtonTitle, nil];
if (self) {
_cancelBlock = Block_copy(cancelBlock);
_downloadBlock = Block_copy(downloadBlock);
_streamBlock = Block_copy(streamBlock);
}
return self;
}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
NSAssert(actionSheet == self, @"Wrong Action Sheet passed");
if (buttonIndex == 0) {
if (self.cancelBlock) {
self.cancelBlock();
}
}
if (buttonIndex == 1) {
if (self.downloadBlock) {
self.downloadBlock();
}
}
if (buttonIndex == 2) {
if (self.streamBlock) {
self.streamBlock();
}
}
}

@end

In my TableView didSelectRowAtIndexPath, I put the following:
BlockBasedActionSheet *askSheet =
[[BlockBasedActionSheet alloc]
initWithTitle:@"What Do You Want To Do" cancelButtonTitle:@"Cancel" downloadButtonTitle:@"Download" streamButtonTitle:@"Stream" cancelAction:^ {

}downloadAction:^ {

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
CGRect frame = CGRectMake(0, 49, 160, 50);
progress = [[UIProgressView alloc] initWithFrame:frame];
cell.contentView.tag = 100;
[cell.contentView addSubview:progress];
RSSEntry *entry = [_allEntries objectAtIndex:indexPath.row];
NSURL *url = [NSURL URLWithString:entry.articleUrl];
self.nameit = entry.articleTitle;
NSURLRequest *theRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];
receivedData = [[NSMutableData alloc] initWithLength:0];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES];

}streamAction:^ {
if (_webViewController == nil) {
self.webViewController = [[[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]] autorelease];
}
RSSEntry *entry = [_allEntries objectAtIndex:indexPath.row];
_webViewController.entry = entry;
[self.navigationController pushViewController:_webViewController animated:YES];
}];
[askSheet showInView:self.tabBarController.view];
[askSheet release];
The Action Sheet Presents from top to bottom:
Download
Stream
Cancel

When I press Download, the Cancel action performs
Stream, the Download action performs
Cancel, the Stream Action performs

Solution:
In the .m of BlockBasedActionSheet, changed to:
if (buttonIndex == [self cancelButtonIndex]) {
if (self.cancelBlock) {
self.cancelBlock();
}
}
if (buttonIndex == [self firstOtherButtonIndex]) {
if (self.downloadBlock) {
self.downloadBlock();
}
}
if (buttonIndex == [self firstOtherButtonIndex] +1) {
if (self.streamBlock) {
self.streamBlock();
}
}
