Ever want to change the color of the magnifying glass in the UISearchBar? Well now you can and you can change its color in interface builder!

	extension UISearchBar {
	/** An easy way to set the magnifying glass color in interface builder
	It is recommended to set this in interface Builder,
	However if you want to do it programatically you can do it like this:
	```
	let searchBar = UISearchBar()
	searchBar.magnifyingGlassColor = UIColor.red
	```

wh1pch81n / UISearchBar_Magnifying_GlassColorChange_withSceneDock.swift

An alternative implementation for setting the magnifying glass color. You need to add this class to the scene dock of your View Controller in interface builder and connect the IBOutlet to the UISearchBar instance. The color for the component can be set on the object in storyboard. The although this is more work than the other approach you have t…

	class UISearchBarMagnifyingGlass: NSObject {
	@IBOutlet weak var searchBar: UISearchBar! {
	didSet {
	if let _color = color, let _searchBar = searchBar {
	for i in _searchBar.subviews.first!.subviews {
	if let textField = i as? UITextField,
	let imageView = textField.leftView as? UIImageView,
	let image = imageView.image
	{
	let coloredImage = image.withRenderingMode(UIImageRenderingMode.alwaysTemplate)

wh1pch81n / UIButtonCalbackExtension.swift

Last active September 3, 2016 04:18

UIButton uses an old objective-c style method to add new callbacks which requires selectors. If you would rather use a block based approach then consider the following approach. You can specify a swift closure to be executed when the button receives a touch event.

	///////////////
	// code example
	//-------------
	button.callback { _ in
	print("hello world") // print "hello world" when touchUpInside event is recieved
	}

	button.callback(for: [.TouchDown]) { _ in
	print("hello world") // print "hello world" when touchDownInside event is recieved
	}

	bootStrap(&s)
	return s
