The successor to F3BarGauge
This control is intended to replicate/simulate the level indicator on an audio mixing board. These indicators are usually segmented/stacked LEDs, with several colors to indicate thresholds. This control replicates that look, using Quartz drawing primitives, and auto-adjusts to horizontal or vertical orientation. Additionally, the colors, number of bars, peak hold, and other items are easily customized. Intended uses include:
- Realtime data visualization
- Level bars
- Single-value charting
- A VERY simple bar chart (if you use several of these)
Adding this control to your XCode project is straightforward:
Add FDBarGauge.swift to your project
Add a new blank subview to your nib/storyboard, sized and positioned to match what the bar gauge should look like.
In the properties inspector for this subview, change the class to "FDBarGauge"
Below class, change the module to "FDBarGauge"
Add an IBOutlet to your view controller
Update your code to set the value property as appropriate.
For more information have a look at the demo code, which has multiple examples including a version that customizes the with an LCD-style appearance.
Following are all of the customizable properties:
/// Whether to maintain a view of local maximums @IBInspectable public var holdPeak: Bool /// This applies a gradient style to the rendering @IBInspectable public var litEffect: Bool /// If `true` then render top-to-bottom or right-to-left @IBInspectable public var reverseDirection: Bool /// The quantity to be rendered @IBInspectable public var value: Double /// The local maximum for `value` @IBInspectable public var peakValue: Double /// The highest possible amount for `value` @IBInspectable public var maxLimit: Double /// The lowest possible amount for `value`, must be less than `maxLimit` @IBInspectable public var minLimit: Double /// A quantity for `value` which will render in a special color @IBInspectable public var warnThreshold: Double /// A quantity for `value` which will render in a special color @IBInspectable public var dangerThreshold: Double /// The number of discrete segments to render @IBInspectable public var numBars: Int /// Outside border color @IBInspectable public var outerBorderColor: UIColor /// Inside border color @IBInspectable public var innerBorderColor: UIColor /// The rendered segment color before reaching the warning threshold @IBInspectable public var normalColor: UIColor /// The rendered segment color after reaching the warning threshold @IBInspectable public var warningColor: UIColor /// The rendered segment color after reaching the danger threshold @IBInspectable public var dangerColor: UIColor
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
CocoaPods 0.39.0+ is required to build FDBarGauge 0.1.0+.
To integrate FDBarGauge into your Xcode project using CocoaPods, specify it in your
source 'https://github.com/CocoaPods/Specs.git' platform :ios, '9.0' use_frameworks! pod 'FDBarGauge'
Then, run the following command:
$ pod install
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update $ brew install carthage
To integrate FDBarGauge into your Xcode project using Carthage, specify it in your
github "fulldecent/FDBarGauge" ~> 0.1
carthage update to build the framework and drag the built
FDBarGauge.framework into your Xcode project.
