UISearchBar custom corners

Question

I'm trying to create a search bar like this:

But I'm noticing that I'm probably going to have to replace the search bar with my own image because the search bar corners comes out wrong when I set:

self.searchController.searchBar.layer.cornerRadius = 50 // I've tried other numbers besides this too with no luck
self.searchController.searchBar.clipsToBounds = true

If I set this:

self.searchController.searchBar.layer.cornerRadius = self.searchController.searchBar.bounds.height/2

The search bar comes out like this:

Which still isn't exact like in the image.

Is there a way to replace the left and right side of the textfield with an image that way I can use the rounded corners from my custom search bar?

Answer 1

The issue here is you are setting the corner radius on the UISearchBar, not the UITextField inside it. You can do some sort of hack to get the UITextField, but that's not really recommended.

As you mentioned in your question, you'll need to use custom images and the methods shown here: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UISearchBar_Class/#//apple_ref/doc/uid/TP40007529-CH3-SW40

I am using this code UISearchBar but you can use this code with UISearchController.

    let searchBar = UISearchBar()
                searchBar.sizeToFit()
                searchBar.placeholder = "Search"
                navigationItem.titleView = searchBar

                if let textfield = searchBar.value(forKey: "searchField") as? UITextField {
                    textfield.textColor = UIColor.blue
                    if let backgroundview = textfield.subviews.first {
                        // Background color
                        backgroundview.backgroundColor = UIColor.white
                        // Rounded corner
                        backgroundview.layer.cornerRadius = 14;
                        backgroundview.clipsToBounds = true;
                    }
                }

This IS working for me in swift 3 iOS 10:

    searchController.searchBar.layer.cornerRadius = 20
    searchController.searchBar.clipsToBounds = true
