Is it possible to change an UIActivityIndicatorView color to black in iOS?

I want to change an activity indicator color gray/white to black. Is it possible to change the color to black? If yes, please guide me or give some sample code.

You can use the .color property in order to change the UIActivityIndicatorView color, e.g.:

// Objective-C
activityIndicator.color = [UIColor greenColor];

// Swift
activityIndicator.color = .green

Note that .color is only available from iOS 5.

It is very easy in Swift 5

@IBOutlet weak var loadingIndicator: UIActivityIndicatorView!       //Declare the UIActivityIndicatorView

override func viewDidLoad() {
   super.viewDidLoad()
   loadingIndicator.style = .medium     //Just change the indicator Style
   loadingIndicator.color = .black      //and change what is your indicator color
}

To use a standard system color:

activityIndicator.color = .green

To use a custom RGBA color

activityIndicator.color = UIColor(displayP3Red: 255/255, green: 150/255, blue: 181/255, alpha: 255/255)

I recommend doing the following:

1. UIActivityIndicatorViewStyle.whiteLarge to make the spinner bigger

2. pick a color

3. pick a backgroundColor to increase contrast

    var activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.whiteLarge)
    activityIndicator.color = UIColor.<YOUR DESIRED COLOR>
    activityIndicator.backgroundColor = UIColor.<YOUR DESIRED BACKGROUND COLOR>
    self.view.addSubview(self.activityIndicator)
   

You can switch between .gray, .white and .whiteLarge by using the .activityIndicatorViewStyle property.
