Objective-c – How to display a set number of rows in UITableView

iphoneobjective cuitableview

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?

thanks!

EDIT: i wasn't too clear about the question so..

So this is my table: http://i.stack.imgur.com/glkWZ.png ..
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?

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.

Ios – How to disable the UITableView selection

All you have to do is set the selection style on the UITableViewCell instance using either:

Objective-C:

cell.selectionStyle = UITableViewCellSelectionStyleNone;

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

Swift 2:

cell.selectionStyle = UITableViewCellSelectionStyle.None

Swift 3 and 4.x:

cell.selectionStyle = .none

Further, make sure you either don't implement -tableView:didSelectRowAtIndexPath: in your table view delegate or explicitly exclude the cells you want to have no action if you do implement it.

Ios – Eliminate extra separators below UITableView

Interface builder (iOS 9+)

Just drag a UIView to the table. In storyboard, it will sit at the top below your custom cells. You may prefer to name it "footer".

Here it is shown in green for clarity, you'd probably want clear color.

Note that by adjusting the height, you can affect how the "bottom bounce" of the table is handled, as you prefer. (Height zero is usually fine).

To do it programmatically:

Swift

override func viewDidLoad() {
    super.viewDidLoad()
    self.tableView.tableFooterView = UIView()
}

Objective-C

iOS 6.1+

- (void)viewDidLoad 
{
    [super viewDidLoad];

    // This will remove extra separators from tableview
    self.tableView.tableFooterView = [UIView new];
}

or if you prefer,

    self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

Historically in iOS:

Add to the table view controller...

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
     // This will create a "invisible" footer
     return CGFLOAT_MIN;
 }

and if necessary...

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{        
    return [UIView new];

    // If you are not using ARC:
    // return [[UIView new] autorelease];
}
