This is custom subclass of UIView, which indicates the progress of task in percent.

• SPWaterProgressIndicatorView_README.md
• SPWaterProgressIndicatorView.hm
• SPWaterProgressIndicatorView.swift
• WaterWaveDemo project demostrates how to use this class in Objective-C Project.
• WaterWaveDemo_Swift project demostrates how to use this class in Swift Project.

• Add SPWaterProgressIndicatorView.hm files to the project.
• There are two ways to use this class:
  • Specify a UIView's class as SPWaterProgressIndicatorView in IB.
  • Using alloc | initWithFrame: (Objective-C) to create and initialize an instance, then add it to a UIView.
  • Using UIView | init(frame: CGRect) (Swift) to create and initialize an instance, then add it to a UIView.

Important to Know

1. Init with init(frame: CGRect)
2. No matter what CGRect being passed to initialize it, the view will be trunked to be a square.

Objective-C

// Initialization.
- (void)viewDidLoad {
    [super viewDidLoad];
    self.waterView = [[SPWaterProgressIndicatorView alloc] initWithFrame:self.view.bounds];
    self.waterView.center = self.view.center;
    [self.view addSubview:self.waterView];
    
}

// Update percent
[self.waterView updateWithPercentCompletion:percent];

Detailed Example in Objc.

Swift

// Initialization
override func viewDidLoad() {
    super.viewDidLoad()
        
    self.wave = SPWaterProgressIndicatorView(frame: self.view.bounds)
    self.wave.center = self.view.center;
    self.view.addSubview(self.wave)        
}

// Update percent
self.wave.completionInPercent = percent
