MAGearRefreshControl is a fully customizable iOS refresh control with gear animation for tableview refresh, writen in Swift.

##Edit from 16/11/15:

A new enum, MAGearStyle, was added in order to custom single gears within the gear group.

• .Normal : Full gear, the one you knew from the beginning :)
• .Branched: Gear with branchs inside of it. Since it's difficult to describe, a picture will help :

Now you can easily add your own gear styles and I will gladly merge them.

##Edit from 23/06/15:

An intermediate class, MAAnimatedMultiGearView, was added in order to animate rotation without having to use an MAGearRefreshControl object.

##Credits:

This project is inspired by this dribble post. The main structure of the refresh Control is based on EGOTableViewPullRefresh.

##How to use:

###Contents:### MAGearRefreshControl is made of five base classes you can use as you wish :

• MAGear : This class represents a gear in the most abstract way, without any graphical code related.
• MASingleGearView : This UIView subclass is used to draw a gear.
• MAMultiGearView : This UIView subclass is used to draw multiples gears.
• MAAnimatedMultiGearView : This MAMultiGearView subclass is used to draw and animate multiple gears
• MAGearRefreshControl : This MAAnimatedMultiGearView subclass is used to draw multiples gears and offers the same interactions as an UIRefreshControl.

###Refresh control###

MAGearRefreshControl must be used from an UITableViewController subclass or UIViewController subclass with an UITableView. Examples are provided for both cases.

refreshControl = MAGearRefreshControl(frame: CGRectMake(0, -self.tableView.bounds.height, self.view.frame.width, self.tableView.bounds.height))
refreshControl.backgroundColor =  UIColor.initRGB(34, g: 75, b: 150)
refreshControl.addInitialGear(nbTeeth:12, color: UIColor.initRGB(92, g: 133, b: 236), radius:16)
refreshControl.delegate = self
self.tableView.addSubview(refreshControl)

You can add new gears easily with a single method :

refreshControl.addLinkedGear(0, nbTeeth:16, color: UIColor.blurColor(), angleInDegree: 30)
refreshControl.addLinkedGear(0, nbTeeth:32, color: UIColor.redColor(), angleInDegree: 190)

// Gear with branch style :
refreshControl.addLinkedGear(1, nbTeeth:14, color: yellowColor(), angleInDegree: 20, gearStyle: .WithBranchs)

// Gear with branch style and custom number of branchs:
refreshControl.addLinkedGear(1, nbTeeth:45, color: greenColor(), angleInDegree: -50, gearStyle: .WithBranchs, nbBranches:12))

Now you have to respect the MAGearRefreshDelegate protocol :

// Method called to know if the data source is loading or no
func MAGearRefreshTableHeaderDataSourceIsLoading(view: MAGearRefreshControl) -> Bool {
    return isLoading
}

// Method called when the pull to refresh move was triggered.
func MAGearRefreshTableHeaderDidTriggerRefresh(view: MAGearRefreshControl) {
    refresh()
}

The refresh control must be notified of scrolling events and when the data is loaded using MAGearRefreshScrollViewDidEndDragging, MAGearRefreshScrollViewDidScrolland MAGearRefreshScrollViewDataSourceDidFinishedLoading methods. The sample project illustrate when to call these methods.

##Licence:

MAGearRefreshControl is under MIT Licence so you can use/modify it as you wish. Any feedback will be appreciated.
