Hi,
I have two tableViews in my application. One works perfectly the other
doesn't. For both I use a simple data source.
The tableView uses numberOfRowsInTableView: (NSTableView *)aTableView to get
the number of rows by doing a count of the objects in my array. This number
happens to be 22. When I run the program I get a zillion empty rows after my
22 rows of data. However if I use the constant 22 as the return value the
tableView displays 22 rows of my data. Any idea about what I am doing wrong?
Here is my code:
-(int) numberOfRowsInTableView: (NSTableView *)aTableView
{
int returnValue;
if (aTableView == gameScoresTableView) //This works as expected
{
if (currentIndex_>= 0)
{
LNPlayer *currentPlayer = [playersArray objectAtIndex:
currentIndex_];
NSMutableArray *tempGameRecordsArray = [NSMutableArray
arrayWithArray: [currentPlayer gameRecordsArray]];
returnValue = [tempGameRecordsArray count];
}
else
{
NSBeep ();
NSLog (@"ERROR in LNAppController --
numberOfRowsInTableView:");
return -1;
}
}
else if (aTableView == playerManagementTableView) //This is the one
that doesn't work
{
returnValue = [playersArray count]; //[playersArray count] = 22
NSLog (@"playersArray count = %d", returnValue); //returnValue
= 22
}
return returnValue; //However if I change this to: return returnValue
= 22 it works fine!
}
-(id) tableView: (NSTableView *) aTableView objectValueForTableColumn:
(NSTableColumn *) aTableColumn row: (int) rowIndex
{
id returnValue = nil;
if (aTableView == gameScoresTableView)
{
LNPlayer *currentPlayer = [playersArray objectAtIndex:
currentIndex_];
NSMutableArray *tempGameRecordsArray = [NSMutableArray
arrayWithArray: [currentPlayer gameRecordsArray]];
id theRecord, theValue;
theRecord = [tempGameRecordsArray objectAtIndex:rowIndex];
theValue = [theRecord objectForKey:[aTableColumn identifier]];
returnValue = theValue;
}
else if (aTableView == playerManagementTableView)
{
//Which Player?
LNPlayer *player = [playersArray objectAtIndex: rowIndex];
//What is the value of the attribute named identifier?
//returnValue = [player valueForKey: [aTableColumn identifier]];
if ([[aTableColumn identifier] isEqualTo: @"firstName_"] == YES)
returnValue = [player firstName_];
else if ([[aTableColumn identifier] isEqualTo: @"lastName_"])
returnValue = [player lastName_];
else if ([[aTableColumn identifier] isEqualTo: @"playerName_"])
returnValue = [player playerName_];
else if ([[aTableColumn identifier] isEqualTo:
@"trebleClefGameLevel_"])
returnValue = [NSNumber numberWithInt: [player
trebleClefGameLevel_]];
else if ([[aTableColumn identifier] isEqualTo:
@"altoClefGameLevel_"])
returnValue = [NSNumber numberWithInt: [player
altoClefGameLevel_]];
else if ([[aTableColumn identifier] isEqualTo:
@"tenorClefGameLevel_"])
returnValue = [NSNumber numberWithInt: [player
tenorClefGameLevel_]];
else if ([[aTableColumn identifier] isEqualTo:
@"bassClefGameLevel_"])
returnValue = [NSNumber numberWithInt: [player
bassClefGameLevel_]];
else if ([[aTableColumn identifier] isEqualTo:
@"symbolTextConcentrationGameLevel_"])
returnValue = [NSNumber numberWithInt: [player
symbolTextConcentrationGameLevel_]];
}
return returnValue;
}
Any help would be much appreciated.
Thanks,
Brian
