Use Block Based Action Sheet - iphone

Question

I am using this 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
What have I done wrong that it is getting out of order?

try this:
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();
}
}
