Scroll left and right on the section scroller to make a selection. Inspiration for this project came from 8tracks iPhone application

Note: KLHorizontalSelect is intended for use with portrait orientation on iPhone/iPad/iPod Touch.

Check out the Demo Excuse the graphics glitches and lag due to my slow computer.

Installation

Drag the included KLHorizontalSelect.h, KLHorizontalSelect.m files into your project. Then, include the following frameworks under Link Binary With Libraries:

• QuartzCore.framework

Usage

Import the required file and declare your controller to conform to the KLHorizontalSelect delegate to recieve callbacks

#import "KLHorizontalSelect.h"
@interface KLViewController : UIViewController <KLHorizontalSelectDelegate>
@property (nonatomic, strong) KLHorizontalSelect* horizontalSelect;
@end

Initialize the control and set the table data with an array of dictionaries (See provided Plist for sample protocol)

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self.navigationController.navigationBar setTintColor:[UIColor colorWithRed:10/255.0 green:37/255.0 blue:70/255.0 alpha:1]];

    //Initialize the informtion to feed the control
    NSString* plistPath = [[NSBundle mainBundle] pathForResource: @"SectionData"
                                                          ofType: @"plist"];
    // Build the array from the plist
    NSArray* controlData = [[NSArray alloc] initWithContentsOfFile:plistPath];

    // Do any additional setup after loading the view, typically from a nib.
    self.horizontalSelect = [[KLHorizontalSelect alloc] initWithFrame: self.view.bounds];
    [self.horizontalSelect setTableData: controlData];
    [self.view addSubview: self.horizontalSelect];

}

Implement the optional delegate method to be notified when a new item is selected

- (void) horizontalSelect:(id)horizontalSelect didSelectCell:(KLHorizontalSelectCell *)cell {
    NSLog(@"Selected Cell: %@", cell.label.text);
}

Config

The visual appearance can be tweaked by changing the constants in KLHorizontalSelect.m:

//Control Properties
#define kDefaultCellWidth 80.0      //The width of each of the items
#define kDefaultCellHeight 90       //Height of the items/control
#define kDefaultGradientTopColor  [UIColor colorWithRed: 242/255.0 green: 243/255.0 blue: 246/255.0 alpha: 1]   //Top Gradient Color
#define kDefaultGradientBottomColor  [UIColor colorWithRed: 197/255.0 green: 201/255.0 blue: 204/255.0 alpha: 1]    //Bottom Gradient Color
#define kDefaultLabelHeight 20.0    //Adjusts the height of the label
#define kDefaultImageHeight 60.0    //Adjusts the height of the image

//Arrow properties
#define kHeaderArrowWidth 40.0      //Adjusts the width of the selection arrow
#define kHeaderArrowHeight 15.0     //Adjusts the width of the selection arrow

//Shadow properties
#define kDefaultShadowColor [UIColor blackColor]
#define kDefaultShadowOffset CGSizeMake(0.0, 3.0)
#define kDefaultShadowOpacity 0.96
