ABSearchBar

Overview

This is a replacement of UISearchController to put a search bar in the UINavigationBar. This is implemented with a simple UITextField which gives greater control via the UITextFieldDelegate methods. The delegate methods can be implemented to do any normal search operation and can be fully customized to appropriate look and feel.

Usage

Make sure your UIViewController is embedded in a UINavigationController either through storyboard or programatically. Drop the SearchBar.swift file into your project, change the extension to your UIViewController class. That's it!

Customizations

The SearchBar.swift file is pretty self explanatory.

Change the look and feel of your Navigation Bar by customizing these lines of code

self.navigationController?.navigationBar.setBackgroundImage(nil, for: .default)
self.navigationController?.navigationBar.shadowImage = nil
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.tintColor = nil

Customize the look and feel of the search bar by modifying these lines of code

searchBar.frame = CGRect(x: 0, y: 0, width: 340, height: 34)
let centeredParagraphStyle = NSMutableParagraphStyle()
centeredParagraphStyle.alignment = .left
let attributes = [
    NSAttributedStringKey.foregroundColor: UIColor(hex: "#37474F"),
    NSAttributedStringKey.paragraphStyle: centeredParagraphStyle
]
self.searchBar.layer.cornerRadius = 15
self.searchBar.backgroundColor = UIColor(hex: "#ECEFF1")
let centerText = NSMutableAttributedString(string: "Search", attributes: attributes)
self.searchBar.attributedPlaceholder = centerText

Change the search bar search glass icon by modifying this-

let image = UIImage(named: "searchfield")
