Hide UITableView search bar by default when in a navigation controller

I've read multiple posts on this but it's not working properly for me. I'm using the latest 4.2 SDK.

The code I have is

self.tableView.contentOffset = CGPointMake(0.0, 44.0);

This partially works, it moves the search bar up a little bit, but it does not get hidden completely. I've tried increasing the value 44 to something greater and this had no affect what so ever! I'm calling this code in the viewDidLoad method of the table's view controller. Does anyone have any ideas?

For others still looking for an updated solution, you can check out my answer over here.

Basically you need to update the contentOffset the first time viewDidLayoutSubviews is called.

I also have the same problem like yours. The following code solved my problem.Please add the code in you viewDidLoad() :

self.edgesForExtendedLayout = UIRectEdgeNone;

N:B: I used autoLayout in my project.

Another approach should be...in viewDidLoad call:

self.tableView.contentInset = UIEdgeInsetsMake(-self.searchDisplayController.searchBar.frame.size.height, 0, 0, 0);

and implementing endDragging delegate method:

-(void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
    CGPoint offset = self.tableView.contentOffset;

    CGFloat barHeight = self.searchDisplayController.searchBar.frame.size.height;
    if (offset.y <= barHeight/2.0f) {
        self.tableView.contentInset = UIEdgeInsetsZero;
    } else {
        self.tableView.contentInset = UIEdgeInsetsMake(-barHeight, 0, 0, 0);
    }

    self.tableView.contentOffset = offset;
}

setting content is to remove some "flickering"

also if You want searchbar to stick at the top, implement didScroll this way:

-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
     CGRect sbFrame = self.searchDisplayController.searchBar.frame;
     sbFrame.origin.y = self.tableView.contentOffset.y;
     if (sbFrame.origin.y > 0) {
         sbFrame.origin.y = 0;
     }
     self.searchDisplayController.searchBar.frame = sbFrame;
}

I hope this will help (took me few days to figure out:) )

Cheers!

UPDATE:

As @carbonr noted You should add this line in viewDidLoad since iOS7+

self.edgesForExtendedLayout = UIRectEdgeNone;

You can set the initial bounds of the table view inside viewDidLoad, so the search bar appears hidden at the beginning.

You have to create the searchBar property and then use following code:

- (void)viewDidLoad
{
    //...
    CGRect bounds = self.tableView.bounds;
    bounds.origin.y = self.tableView.bounds.origin.y + searchBar.bounds.size.height;
    self.tableView.bounds = bounds;
    //...
}

self.tableView.contentOffset = CGPointMake(0.0, 44.0);

The above code does in fact work but it needs to run after the UITableView has finished creating all of its cells. I guess thats another question though.
