Scroll Rate

The scroll rate property of each column is measured in [pixel/second] and can be set individually for each column. This value should be set via the KLScrollViewDataSource implementation. Defaults to 10 pixel/second if datasource not implemented

Installation

1. Drag the KLScrollSelect.xcodeproj to your existing project
2. Under Build Phases on your project's Xcode Project file add 'KLScrollSelect(KLScrollSelect)' to your Target Dependancies
3. Under Build on your Xcode Project file add 'libKLScrollSelect' & QuartzCore.framework under Link Binary With Libraries
4. Include #import <KLScrollSelect/KLScrollSelect.h> in any file you wish to use

Via CocoaPods Add the following line to your podfile

pod 'KLScrollSelect'

Usage

Import the header file and declare your controller to subclass KLScrollViewController

#import <KLScrollSelect/KLScrollSelect.h>
@interface KLViewController : KLScrollSelectViewController

OR, Import the header file and declare your controller to conform to KLScrollSelectDelegate and KLScrollSelectDataSrouce

#import <KLScrollSelect/KLScrollSelect.h>
@interface KLViewController : UIViewController <KLScrollSelectDataSource, KLScrollSelectDelegate>

Implement the required methods for KLScrollSelectDataSource

@required
- (NSInteger)scrollSelect:(KLScrollSelect *)scrollSelect numberOfRowsInColumnAtIndex:(NSInteger)index;
- (UITableViewCell*) scrollSelect:(KLScrollSelect*) scrollSelect cellForRowAtIndexPath:(NSIndexPath *)indexPath;
@optional
- (CGFloat) scrollSelect: (KLScrollSelect*) scrollSelect heightForColumnAtIndex: (NSInteger) index;
- (CGFloat) scrollRateForColumnAtIndex: (NSInteger) index;
- (NSInteger)scrollSelect:(KLScrollSelect *)scrollSelect numberOfSectionsInColumnAtIndex:(NSInteger)index;
// Default is 1 if not implemented
- (NSInteger)numberOfColumnsInScrollSelect:(KLScrollSelectViewController *)scrollSelect;

Implement the optional methods for KLScrollSelectDelegate

@optional
- (void)scrollSelect:(KLScrollSelect *)tableView didSelectCellAtIndexPath:(NSIndexPath *)indexPath;

NSIndexPath Add-on Implements a category which adds column to NSIndexPath. This allows NSIndexPath to identify which cell in which column as follows:

column: Identifies to column in the KLScrollView
section: Identifies the section (As one would expect with UITableView column on NSIndexPath)
row: Identifies the row (As one would expect with UITableView row on NSIndexPath)
