RZVibrantButton is a stylish button with iOS 8 vibrancy effect built using Swift. It is a subclass of UIButton that has a simple yet elegant appearance and built-in support for UIVisualEffectView and UIVibrancyEffect classes introduced in iOS 8. Yet, it can be used on iOS 7 without the vibrancy effect. The design of this button is inspired by "AYVibrantButton" by alan yip.

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Configurations

Vibrant buttons can be configured with one of the three supported button styles, invert, translucent and fill (see examples below).

Some basic properties like icon, text, font, alpha, corner radius, border width and background color (for no vibrancy effect) can all be changed easily.

The default vibrancy effect is for blur effect UIBlurEffectStyleLight. It could be set to any UIVibrancyEffect instance. For today extensions, it should be set to [UIVibrancyEffect notificationCenterVibrancyEffect].

Note

Though vibrant buttons can be placed anywhere, it is recommended that vibrant buttons with vibrancy effects should be placed in the contentView of UIVisualEffectView (except in today view).

UIVisualEffectView can be created as follows.

var effectView:UIVisualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: UIBlurEffectStyle.ExtraLight))
effectView.frame = self.view.bounds;
self.view.addSubview(effectView)

Examples

The following images show the normal and highlighted (being pressed) button appearances.

Invert style with vibrancy effect

var invertButton:RZVibrantButton = RZVibrantButton(frame:CGRectZero, style:RZVibrantButtonStyle.Invert)
invertButton.vibrancyEffect = UIVibrancyEffect(forBlurEffect: UIBlurEffect(style: UIBlurEffectStyle.ExtraLight))
invertButton.text = "Invert"
invertButton.font = UIFont.systemFontOfSize(18.0)
effectView.contentView.addSubview(invertButton)

Translucent style with vibrancy effect

var translucentButton:RZVibrantButton = RZVibrantButton(frame:CGRectZero, style:RZVibrantButtonStyle.Translucent)
translucentButton.vibrancyEffect = UIVibrancyEffect(forBlurEffect: UIBlurEffect(style: UIBlurEffectStyle.ExtraLight))
translucentButton.text = "Translucent";
translucentButton.font = UIFont.systemFontOfSize(18.0)
effectView.contentView.addSubview(translucentButton)

Translucent style without vibrancy effect

var button:RZVibrantButton = RZVibrantButton(frame:CGRectZero, style:RZVibrantButtonStyle.Translucent)
button.vibrancyEffect = nil;
button.text = "Any Color";
button.font = UIFont.systemFontOfSize(18.0)
button.backgroundColor = UIColor.blackColor()
effectView.contentView.addSubview(button)
