iOS Buttons that animate while an action is being processed. Written in Swift.
This library was extracted from an iOS application that I was working on at the time. It's used for any sort of action that is processed asynchronously, and shows a loading-like animation until the action is done.
Basic asynchronous task animation
@IBOutlet weak var btnSignIn: ProcessButton!
btnSignIn.animate(true)
// Do some some asynchronous stuff here
// and display result from callback
if callbackSuccess {
self.btnSignIn.showSuccessText("Success", seconds: ProcessButtonUtil.Length.Short)
} else {
self.btnSignIn.showErrorText("Error", seconds: ProcessButtonUtil.Length.Long)
}
Optional To change the colors of the lines and the duration, put this in your AppDelegate didFinishLaunchingWithOptions
// App wide customization
let colors = [UIColor.blueColor(), UIColor.redColor(), UIColor.greenColor()]
let duration: NSTimeInterval = 0.3
ProcessButtonUtil.sharedInstance
.setColors(colors) // The colors for the animating lines. Can be any number of colors
.setDuration(duration) // The time for each line to animate. Default is 0.5
Take a look at the project to see a full example.
