macOS nstableview delegate method is not getting called

[hrishidev]

Hi friends
i m using nstableview , defined these two methods of data source

- (int)numberOfRowsInTableView🙁NSTableView *)aTableView;

- (id)tableView🙁NSTableView *)aTableView
objectValueForTableColumn🙁NSTableColumn *)aTableColumn
row🙁int)rowIndex;


for addition customization , i set delegate
and called following methods
- (float)tableView🙁NSTableView *)tableView heightOfRow🙁int)row;

- (BOOL)tableView🙁NSTableView *)aTableView shouldEditTableColumn🙁NSTableColumn *)aTableColumn row🙁int)rowIndex;

but this method is not getting called

- (NSCell *)tableView🙁NSTableView *)tableView dataCellForTableColumn🙁NSTableColumn *)tableColumn row🙁int)row;


the nstalbeview is inside one customview which is on nswindow
also i have to use
int instead of 'NSInteger ' in methods
- (float)tableView🙁NSTableView *)tableView heightOfRow🙁NSInteger)row; ....can this be any indication of problem ???


i tried the same thing outside my project in one sample application its working fine .......


can you tell me where I m going wrong ????
