RecordButton

A Record Button in Swift. Inspired by SDRecordButton It shows you the recording process when recording. It's great for a video recorder app with a fixed/maximum length like snapchat, vine, instragram.

Requirements

iOS 8 and higher

Example Project

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

Installation

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

pod "RecordButton"

Add this line add the top of the file you want to use this module in import RecordButton

Usage

Add a simple RecordButton

Add this to viewDidLoad

let recordButton = RecordButton(frame: CGRectMake(0,0,70,70))
view.addSubview(recordButton) 

Update progress

it's the easiest to just check out the example project for this.

To update progress the RecordButton must be an instance of the class. You should also add a progressTimer and a progress variable, like this:

class ViewController: UIViewController {

	var recordButton : RecordButton!
	var progressTimer : NSTimer!
	var progress : CGFloat! = 0
	
	// rest of viewController 
	

The recordButton needs a target for start and stopping the progress timer. Add this code after initialization of the recordButton (usualy in viewDidLoad())

recordButton.addTarget(self, action: #selector(ViewController.record), for: .touchDown)
recordButton.addTarget(self, action: #selector(ViewController.stop), for: UIControlEvents.touchUpInside)

Finally add these functions to your ViewController

    @objc func record() {
        self.progressTimer = Timer.scheduledTimer(timeInterval: 0.05, target: self, selector: #selector(ViewController.updateProgress), userInfo: nil, repeats: true)
    }
    
    @objc func updateProgress() {
        
        let maxDuration = CGFloat(5) // Max duration of the recordButton
        
        progress = progress + (CGFloat(0.05) / maxDuration)
        recordButton.setProgress(progress)
        
        if progress >= 1 {
            progressTimer.invalidate()
        }
        
    }
    
    @objc func stop() {
        self.progressTimer.invalidate()
    }
