ISHHoverBar

A floating UIToolBar replacement as seen in the iOS 10 Maps app, supporting both vertical and horizontal orientation.

It is designed to hover above your content and it plays nicely with auto layout. Combine it with ISHPullUp to create a UI resembling the iOS 10 Maps app.

`ISHHoverBarOrientationVertical`	`ISHHoverBarOrientationHorizontal`

The content of the bar is set using UIBarButtonItems, just as you would configure a UIToolBar. The bar is backed by a UIVisualEffectsView allowing you to choose from several styles. You can customize most aspects of the view via Interface Builder.

Basic usage

Setting the bar's contents

ISHHoverBar is populated similarly to a UIToolbar using instances of UIBarButtonItem. The content can be changed at any time by setting the items property. The layout and intrinsicContentSize will automatically be updated.

A few limitation apply: ISHHoverBar only supports instances of UIBarButtonItem that have a title, image, or customView (subclass of UIControl). Most importantly, UIBarButtonItem instances created using a UIBarButtonSystemItem are not supported as access to the underlying content is restricted to private APIs.

Appearance and orientation

ISHHoverBar supports vertical and horizontal layouts. The orientation can be changed at any time by setting the orientation property (default is vertical). Use auto layout to position the bar in your view hierarchy.

The following aspects of ISHHoverBar can be changed via code or Interface Builder:

Shadow:
- shadowColor
- shadowOpacity
- shadowRadius
Corner radius: cornerRadius
Border (also applied to separators between items):
- borderWidth
- borderColor
Background visual effect: effect

Item background color

The color can easily be changed by changing the backgroundColor property of the UIBarButtonItem.

Item size

If you want to change the item size to a fixed length you can pass an object that conforms to ISHHoverBarItemType. This onyl has the additional attribute CGFloat length. After chaning the length call [self.hoverbar reload] to apply the changes.

General info

ISHHoverBar is written in Objective-C to allow easy integration into any iOS project and has fully documented headers. It is annotated for easy integration into Swift code bases.

The ISHHoverBar class and sample app have a Deployment Target of iOS 8.

Integration into your project

Dynamically-linked framework

Add the project file ISHHoverBar.xcodeproj as a subproject of your app. Then add the framework ISHHoverBar.framework to the app's embedded binaries (on the General tab of your app target's settings). On the Build Phases tab, verify that the framework has also been added to the Link Binary with Libraries phase, and that an Embed Frameworks phase has been created (unless it existed before).

The framework can be used as a module, so you can use @import ISHHoverBar; (Objective-C) and import ISHHoverBar (Swift) to import all public headers.

Further reading on Modules: Clang Documentation

Include files directly

Currently the project relies on a single implementation file and its header. You can include them directly into your project:

ISHHoverBar/ISHHoverBar.{h/m}

CocoaPods

You can use CocoaPods to install ISHHoverBar as a static library. Add this to your Podfile:

target 'MyApp' do
  pod 'ISHHoverBar'
end

ISHHoverBar can also be installed as a framework:

target 'MyApp' do
  use_frameworks!
  pod 'ISHHoverBar'
end

See the official website to get started with CocoaPods.

Carthage

Since ISHHoverBar can be built as a framework, it supports Carthage, too. Add this to your Cartfile:

github iosphere/ISHHoverBar

See the Carthage repository to get started with Carthage.
