Activity - iOS (Objective-C)

Activity is a UIView subclass that creates a customizable loading activity indicator like control.

• Mimics Apple loading indicator from App Store & Music

Requirements

• iOS 7.0 or later. (Uses UIKit Dynamics)
• QuartzCore.framework
• ARC enabled.

Installation

• Want a Pod for this, just add following line to your podfile-

pod 'Activity'

• You can directly copy the source files from Activity folder.

How To Use

Configuring Activity is as simple as :

Activity* activity = [[Activity alloc] initWithStyle:ActivityStyleAppStoreBlue];
activity.frame = CGRectMake(50, 50, 30, 30);
[self.view addSubview:activity];
[activity startAnimating];

Activity takes it over from here. You just need to know start/stop animating.

Properties

Activity comes with a property set for it's customization as needed :-

• style : Choose a style convenient to you from 'StyleActivity' enum

• ringTintColor : Color for ring displayed as loading circle

• circulatorTintColor : Color for small circulator traversing ring's circumference

• ringThickness : Thickness for Ring (Default : 1)

• ringSize : Diameter for Ring (Default : 28)

• durationForOneRevolution : Duration for completing one Revolution. (Default : 1)

[UIColor colorWithPatternImage:] advantage

Given that UIColor is capable of color patterns handling made from images, 
Activity can be used to take advantage of this feature.
