How to install it?

CocoaPods is the easiest way to install KMAccordionTableViewController. Run pod search KMAccordionTableViewController to search for the latest version. Then, copy and paste the pod line to your Podfile. Your podfile should look like:

pod 'KMAccordionTableViewController'

Finally, install it by running pod install.

If you don't use CocoaPods, import the all files from "Classes" directory to your project.

#import "KMAccordionTableViewController.h"

@interface MyViewController : KMAccordionTableViewController

@end

Implement KMAccordionTableViewControllerDataSource

- (NSInteger)numberOfSectionsInAccordionTableViewController:(KMAccordionTableViewController *)accordionTableView;

- (KMSection *)accordionTableView:(KMAccordionTableViewController *)accordionTableView sectionForRowAtIndex:(NSInteger)index;

- (CGFloat)accordionTableView:(KMAccordionTableViewController *)accordionTableView heightForSectionAtIndex:(NSInteger)index;

- (UITableViewRowAnimation)accordionTableViewOpenAnimation:(KMAccordionTableViewController *)accordionTableView;

- (UITableViewRowAnimation)accordionTableViewCloseAnimation:(KMAccordionTableViewController *)accordionTableView;

Customization

@property(nonatomic, assign) NSInteger headerHeight; //Sets section header height.
@property(nonatomic, strong) UIFont *headerFont; //Sets section header font.
@property(nonatomic, strong) UIColor *headerTitleColor; //Sets section header font color.
@property(nonatomic, strong) UIColor *headerColor; //Sets section header background color.
@property(nonatomic, strong) UIColor *headerSeparatorColor; //Sets section header separator color.
@property(nonatomic) UIImage *headerArrowImageOpened; //Sets section header disclosure opened image.
@property(nonatomic) UIImage *headerArrowImageClosed; //Sets section header disclosure closed image.

- (void)setOneSectionAlwaysOpen:(BOOL)isOpen; //set if one section should always be open. if set to YES, the VC will load with the first section already open, and the open section will not close unless you click a different section

Example

#import "MyViewController.h"

}

- (CGFloat)accordionTableView:(KMAccordionTableViewController *)accordionTableView heightForSectionAtIndex:(NSInteger)index{
    KMSection *section = self.sections[index];
    return section.view.frame.size.height;
}

- (UITableViewRowAnimation)accordionTableViewOpenAnimation:(KMAccordionTableViewController *)accordionTableView
{
    return UITableViewRowAnimationFade;
}
