Installation

Cocoapods: pod 'SEFilterControl'

Manual:

1. In your Xcode Project, take the SEFilterControl.h and .m & SEFilterKnob.h and .m from ios-filter-control folder and drag them into your project.

2. Start using this new UIControl Subclass!

SDK Support

It supports iOS 5 to iOS 8 Live rendering in Interface builder will require Xcode 6.x

Usage

Creating your filter

By Code

Somewhere, for example in your viewDidLoad, alloc and init the filter UIControl:

SEFilterControl *filter = [[SEFilterControl alloc]initWithFrame:CGRectMake(10, 20, 300, 70) Titles:[NSArray arrayWithObjects:@"Articles", @"News", @"Updates", @"Featured", @"Newest", @"Oldest", nil]];

This initializes our Filter Control using CGRect and Titles Array of NSStrings.

Note That height of the control is predefined as 70 and can't be changed Use SEFilterControl_HEIGHT const for reference.

Then, add target for Value Change Event handling:

[filter addTarget:self action:@selector(filterValueChanged:) forControlEvents:UIControlEventValueChanged];

Don't forget to implement the handler we specified later:

-(void)filterValueChanged:(SEFilterControl *) sender{
	NSLog(@"%@", [NSString stringWithFormat:@"%d", sender.SelectedIndex]);
}

Adding to your UIView:

	[self.view addSubview:filter];

Via Interface builder

Add a new UIView to your xib, and update its class to SEFilterControl. Bind a UIAction to the valueChanged event of your control. Enjoy ;)
