i am trying to display a simple UITableView with some data. I wish to set the static height of the UITableView so that it doesn't displays empty cells at the end of the table. how do I do that?

code:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    NSLog(@"%d", [arr count]);
    return [arr count];
}

回答1:

Set a zero height table footer view (perhaps in your viewDidLoad method), like so:

Swift:

tableView.tableFooterView = UIView()

Objective-C:

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

Because the table thinks there is a footer to show, it doesn't display any cells beyond those you explicitly asked for.

Interface builder pro-tip:

If you are using a xib/Storyboard, you can just drag a UIView (with height 0pt) onto the bottom of the UITableView.

回答2:

Swift 3 syntax:

tableView.tableFooterView = UIView(frame: .zero)

Swift syntax: < 2.0

tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

Swift 2.0 syntax:

tableView.tableFooterView = UIView(frame: CGRect.zero)

回答3:

In the Storyboard, select the UITableView, and modify the property Style from Plain to Grouped.

回答4:

Implemented with swift on Xcode 6.1

self.tableView.tableFooterView = UIView(frame: CGRectZero)
self.tableView.tableFooterView?.hidden = true

The second line of code does not cause any effect on presentation, you can use to check if is hidden or not.

I can not add comment as of now so adding this as an answer.

@Andy's answer is good and the same results can be achieved with the following line of code:

tableView.tableFooterView = [UIView new];

'new' method belongs to NSObject class and invokes alloc and init methods for UIView.

回答6:

I tried the code:

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

In the viewDidLoad section and xcode6 showed a warning. I have put a "self." in front of it and now it works fine. so the working code I use is:

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

回答7:

or you can call tableView method to set the footer height in 1 point, and it will add an last line, but you can hide it too, by setting footer background color.

code:

func tableView(tableView: UITableView,heightForFooterInSection section: Int) -> CGFloat {
     return 1
}

looks like last line

Using UITableViewController

The solution accepted will change the height of the TableViewCell. To fix that, perform following steps:

1. Write code snippet given below in ViewDidLoad method.

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

2. Add following method in the TableViewClass.m file.

   - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
   {
       return (cell height set on storyboard); 
   }
   

That's it. You can build and run your project.

回答9:

override func viewWillAppear(animated: Bool) {
    self.tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

/// OR 

    self.tableView.tableFooterView = UIView()
}

回答10:

in the below method:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (([array count]*65) > [UIScreen mainScreen].bounds.size.height - 66)
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [array count]*65)); 
    }
    else
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [UIScreen mainScreen].bounds.size.height - 66);
    }
    return [array count];
}

here 65 is the height of the cell and 66 is the height of the navigation bar in UIViewController.
