UIKit port of SpinKit.

CocoaPods is the recommended way for adding SpinKit to your project.

pod 'SpinKit', '~> 1.1'

If you are not yet using CocoaPods, I definetly recommend you to check out their Getting Started guide and the NSHipster article.

Simply instantiate RTSpinKitView with the desired style and add to your view hierarchy.

#import <SpinKit/RTSpinKitView.h>
...
RTSpinKitView *spinner = [[RTSpinKitView alloc] initWithStyle:RTSpinKitViewStyleWave];
[self.view addSubview:spinner];

You can change the size of the spinner by manipulating the spinnerSize property. The default size is 37.0.

spinner.spinnerSize = 100.0;
[spinner sizeToFit];

Available styles:

• RTSpinKitViewStylePlane
• RTSpinKitViewStyleCircleFlip
• RTSpinKitViewStyleBounce
• RTSpinKitViewStyleWave
• RTSpinKitViewStyleWanderingCubes
• RTSpinKitViewStylePulse
• RTSpinKitViewStyleChasingDots
• RTSpinKitViewStyleThreeBounce
• RTSpinKitViewStyleCircle
• RTSpinKitViewStyle9CubeGrid
• RTSpinKitViewStyleWordPress
• RTSpinKitViewStyleFadingCircle
• RTSpinKitViewStyleFadingCircleAlt
• RTSpinKitViewStyleArc
• RTSpinKitViewStyleArcAlt

SpinKit integrates nicely with the amazing MBProgressHUD library:

RTSpinKitView *spinner = [[RTSpinKitView alloc] initWithStyle:RTSpinKitViewStyleWave color:[UIColor whiteColor]];
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.square = YES;
hud.mode = MBProgressHUDModeCustomView;
hud.customView = spinner;
hud.labelText = NSLocalizedString(@"Loading", @"Loading");
[spinner startAnimating];
