Customize UISearchBar: Trying to get rid of the 1px black line underneath the search bar

Question

My question is already specified in the title: I would like to get rid of the black line drawn on the bottom of the UISearchBar. Any ideas?

Here's an image of what I mean:

UPDATE:

I think that the line is part of the UITableView's tableHeaderView. I still don't know how to remove it.

Solution 1

I fixed this by adding a subview to the searchBar's view stack like so:

CGRect rect = self.searchBar.frame;
UIView *lineView = [[UIView alloc]initWithFrame:CGRectMake(0, rect.size.height-2,rect.size.width, 2)];
lineView.backgroundColor = [UIColor whiteColor];
[self.searchBar addSubview:lineView];

Here, self.searchBar is an UISearchBar pointer of my controller class.

Solution 2

Try this

 searchBar.layer.borderWidth = 1;

 searchBar.layer.borderColor = [[UIColor lightGrayColor] CGColor];

Solution 3

Why:

So, I've dug into the API's trying to figure out why this is happening. Apparently whomever wrote the UISearchBar API is rasterizing the lines onto an image and setting it as it's backgroundImage.

Solution:

I propose a simpler solution, if you want to set the backgroundColor and get rid of the hairlines:

searchBar.backgroundColor = <#... some color #>
searchBar.backgroundImage = [UIImage new];

Or if you just need a background image without the hairlines:

searchBar.backgroundImage = <#... some image #>

Solution 4

I have 0.5px black horizontal lines both on top and on the bottom of my UISearchBar. The only way I had so far to get rid of them is by setting its style to Minimal:

mySearchBar.searchBarStyle = UISearchBarStyleMinimal;

Thank you for your solutions. Unluckily both solutions don't cover the line. Maybe is it a drop shadow on top of the table view? Strange!

I added the line in the layoutSubviews method of a UISearchBar's subclass. I was working with a subclass anyway.

This hides the search text input field instead of the bar's bottom line.

"Set the tableHeaderView to nil before putting your UISearchBar there..." Why does this work?

[Paludis]

Works for me, in my case I am using a custom bar tint color so my code is as follows (swift): searchBar.layer.borderColor = searchBar.barTintColor?.CGColor

[Adam Eberbach]

What helped me see why it works was to mistakenly set "searchBar.layer.borderColor = searchBar.tintColor?.CGColor"

[Iulian Onofrei]

So one says to add searchBar.layer.borderColor = searchBar.barTintColor?.CGColor and one to remove that -_-

For iOS7+ you'll want to use the setBackgroundImage:forBarPosition:barMetrics: method instead.

This makes textfield greyed inside serachbar

This solution removes the bar. Thanks @Oxcug!
