ROStorageBar

ROStorageBar is a library which provides an easy way to create an UIView which looks similar like the iTunes Usage Bar.

It is also possible to add captions underneath the bar.

Installation

ROStorageBar is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "ROStorageBar"

How to use

The usage is really straighforward. Create a UIView in the Storyboard and set the class to ROStorageBar.

In the viewDidLoad Method you can add ROStorageBarValues with the following code:

override func viewDidLoad() {
    super.viewDidLoad()

    storageBar.add(0.2, title: "Apps", color: UIColor(hex:"#FFABAB"))
    storageBar.add(0.15, title: "Documents", color: UIColor(hex:"#FFD29B"))
    storageBar.add(0.21, title: "Photos", color: UIColor(hex:"#DDEBF9"))
    storageBar.add(0.3, title: "Movies", color: UIColor(hex:"#c3c3c3"))

    // Or if you want to use directly the struct to add an item
    storageBar.addStorageBarValue(ROStorageBarValue(value: 0.6, title: "Backups", color: UIColor(hex:"#A8DBA8")))

    storageBar.unit = "GB"
    storageBar.displayTitle = false
    storageBar.displayValue = false
    storageBar.displayCaption = true
    storageBar.titleFontSize = 10.0
    storageBar.valueFontSize = 10.0

    var numberFormatter = NSNumberFormatter()
    numberFormatter.maximumFractionDigits = 2
    numberFormatter.minimumIntegerDigits = 1

    storageBar.numberFormatter = numberFormatter
}

The size of the ROStorageBar is defined by the size of the UIView. Therefore also AutoLayout is perfectly working with the ROStorageBar and the adaptation and rerendering is automatically handled by the Library itself. If you have set the displayCaptions to true it does automatically split the view in half. It uses the upper half for the bar and the lower bar for the captions. If there aren't any captions it takes the full height of the UIView.
