Question

I implemented a UIAlertView that displays a tableView to make a selection and return to the underlying view controller.

The alert view pops up fine, displays all the data and when I click the cancel button it does not respond, then I click it again and it moves position by quarter of an inch, then when I click it for the third time, the alertView finally disappears.

What would cause this type of behavior?

This is the code:

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
CGPoint p = [gestureRecognizer locationInView:self.tableView];

NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
if (indexPath == nil){
    NSLog(@"long press on table view but not on a row");
}
else {
    NSLog(@"long press on table view at row %d", indexPath.row);
    selectedQuote = [self.quotes objectAtIndex:indexPath.row];

    NSLog(@"         subject title = %@", selectedQuote.title);

    // NOW PULL UP THE ADD QUOTE MAP CONTROLLER SO THIS QUOTE CAN BE ADDED TO ANOTHER CATEGORY

    if(aqmController == nil)
        aqmController = [[AddQuoteMapController alloc] initWithNibName:@"AddQuoteMapController" bundle:nil];

    aqmController.selectedQuote = self.selectedQuote;

    //POP UP SBTableAlert

    SBTableAlert *alert;
    alert   = [[SBTableAlert alloc] initWithTitle:@"Categorize this Quote" cancelButtonTitle:@"Cancel" messageFormat:@""];

    [alert setType:SBTableAlertTypeMultipleSelct];
    [alert.view addButtonWithTitle:@"OK"];
    [alert.view setTag:0];
    [alert setStyle:SBTableAlertStyleApple];

    [alert setDelegate:self];
    [alert setDataSource:self];

    [alert show];

}

}

#pragma mark - SBTableAlertDataSource

- (UITableViewCell *)tableAlert:(SBTableAlert *)tableAlert cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell;

cell = [[[SBTableAlertCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];

Category *cat = [categories objectAtIndex:indexPath.section];

Subject *sub = [cat.subjects objectAtIndex:indexPath.row];

cell.textLabel.text =sub.title;   
cell.detailTextLabel.text = sub.category_title;

return cell;

}

- (NSInteger)tableAlert:(SBTableAlert *)tableAlert numberOfRowsInSection:(NSInteger)section {

Category *cat = [categories objectAtIndex:section];
return cat.subjects.count;

}

- (NSInteger)numberOfSectionsInTableAlert:(SBTableAlert *)tableAlert {

self.categories = [appDelegate categories];

return self.categories.count;

}

- (NSString *)tableAlert:(SBTableAlert *)tableAlert titleForHeaderInSection:(NSInteger)section {

Category *cat = [categories objectAtIndex:section];

//INSERT INTO QUOTEMAP TABLE

// GET SUBJECT_ID
NSString *stringOfSubjectId = [NSString stringWithFormat:@"%d", selectedSubject.subject_id];

NSLog(@"mySubjectId= %@", stringOfSubjectId);

// GET THE NEXT QUOTE_MAP_ID

QuotesAppDelegate *appDelegate = (QuotesAppDelegate *)[[UIApplication sharedApplication] delegate];
QuoteMap *qm = [[QuoteMap alloc] init];

NSInteger newQuoteMapId = [appDelegate getNextQuoteMapId];
NSLog(@"quote_map_id= %d   subId = %@   quoteId = %@", newQuoteMapId, stringOfSubjectId, selectedQuote.quote_id);

// INSERT INTO QUOTE_MAP TABLE
NSString *stringOfId = [NSString stringWithFormat:@"%d", newQuoteMapId];

qm.quote_map_id = stringOfId;
qm.subject_id   = stringOfSubjectId;

//qm.isDirty      = YES;

[qm insertQuoteMap:qm];

//Add it to the array.
[qmv.quoteMaps addObject:qm];
[qmv.tableView reloadData];

if (tableAlert.type == SBTableAlertTypeMultipleSelct) {
    UITableViewCell *cell = [tableAlert.tableView cellForRowAtIndexPath:indexPath];
    if (cell.accessoryType == UITableViewCellAccessoryNone)

}

[categories release]; 
[selectedSubject release];

}

Perhaps you should be using SBTableAlertDatasource and SBTableAlertDelegate methods instead of the UITableViewDatasource and UITableviewDelegate methods.

Also gesture is UILongPressGestureRecognizer. That is a continuous recognizer. You need to check for the state of the recognizer and ignore all the events that come after UIGestureRecognizerStateBegan
