How do i display set number of rows in a UITableView?
i.e if my data source has only 4 objects then i want the table to display on those 4 rows without any blank rows. any ideas?

i want to display only the 3 rows and not the blank rows below it. The number of rows change depending on my data source.
any ideas how to go about doing so?

Answer 1

You have to change your table appearance, I think. Once you correctly set the numberOfSectionsInTableView: and tableView:numberOfRowsInSection: methods, you should change your viewDidLoad method adding this line:
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
This way you will remove all lines from the table.
If you still want to make a line appear between lines, I suggest you to create a custom UITableViewCell, or to build a standard one adding a subview to mimic the line. Eg. something like this:
CGRect lineFrame = CGRectMake(0,cell.frame.size.height-1,cell.frame.size.width,1);
UIView *line = [[UIView alloc] initWithFrame:lineFrame];
line.backgroundColor = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:1];
[cell.contentView addSubview:line];
[line release];
Let me know if this helps.

Check the UITableView DataSource protocol, there are two relevant methods you have to implement:
– numberOfSectionsInTableView:
– tableView:numberOfRowsInSection:
The first one should return 1, the second one 4.

Answer 3

If you want to keep a set number of lines in your tableview and not display the extra blank lines, you could insert a empty footer view in viewdidload function.
self.tableview.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

Answer 4

I did not actually understand what you mean with "display on those 4 rows without any blank rows" but I guess what you ask is just a simple data retrieval process. I suppose the data source is NSarray.
-numberOfRowsInSection:(NSInteger)section{
return [MyArray count];
}
-cellForRowAtIndexPath(NSIndexPath*)indexPath{
NSInteger row=indexPath.row;
cell.textLabel.Text=[MyArray objectAtIndex:row]
return cell;
}
I assume you know what should be put in those blank spaces.I just wrote the major points.

try this
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 4
}
also implements the rest of delegate methods required to populate tableview..
Hope it helps you.......
