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

pod 'NVActivityIndicatorView-ObjC'

#import <NVActivityIndicatorView_ObjC/NVActivityIndicatorView.h>

// Create an activity indicator
NVActivityIndicatorView *activityIndicatorView = [[NVActivityIndicatorView alloc]
    initWithFrame:CGRectMake(0, 0, 40, 40)
             type:NVActivityIndicatorTypeBallPulse
            color:[UIColor blueColor]
          padding:0];

// Add to your view
[self.view addSubview:activityIndicatorView];

// Create with custom animation speed
NVActivityIndicatorView *activityIndicatorView = [[NVActivityIndicatorView alloc]
    initWithFrame:CGRectMake(0, 0, 40, 40)
             type:NVActivityIndicatorTypeBallPulse
            color:[UIColor redColor]
          padding:0];

// Set animation speed (1.0 = normal, 2.0 = 2x faster, 0.5 = 2x slower)
activityIndicatorView.animationSpeedMultiplier = 1.5;

[self.view addSubview:activityIndicatorView];
