EMAccordionTableViewController

EMAccordionTableViewController is a easy to use Expandable / Collapsable UITableView for iOS. Under the hood it works as a proxy for the UITableView and leaves to the delegate the responsability to implement tableView:cellForRowAtIndexPath and tableView:didSelectRowAtIndexPath.

Update: Now it support the header view with parallax effect. I have used UIImage+ImageEffects from wwdc2013 to support the blur.

Built to be Universal
Support rotation
Completely reusable component

How to install it?

CocoaPods

The recommended approach is to install EMAccordionTableViewController via CocoaPods.

platform :ios, '6.0'
pod 'EMAccordionTableViewController', '~> 0.5.4'

And then install it running

$ pod install

And now open the project in Xcode from the .xcworkspace file, not from the project file

$ open YourOwnProject.xcworkspace

Source Code

Alternatively you can just copy all the files included in the folder EMAccordionTable and start playing with it!

How it works?

EMAccordionTableViewController Class

@interface EMAccordionTableViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>

@property (nonatomic, strong) UIImage * closedSectionIcon;
@property (nonatomic, strong) UIImage * openedSectionIcon;
@property (nonatomic, strong) UITableView *tableView;
@property (nonatomic, strong) EMAccordionTableParallaxHeaderView *parallaxHeaderView;
@property (nonatomic, strong) NSMutableArray *sectionsHeaders;
@property (nonatomic) NSInteger defaultOpenedSection;

- (id) initWithTable:(UITableView *)tableView withAnimationType:(EMAnimationType) type;

- (void) addAccordionSection: (EMAccordionSection *) section initiallyOpened:(BOOL)opened;
- (void) setDelegate: (NSObject <EMAccordionTableDelegate> *) delegate;

@end

### EMAccordionTableDelegate Protocol
@protocol EMAccordionTableDelegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section;
- (void) latestSectionOpened;
@end

EMAccordionSection Class

@interface EMAccordionSection : NSObject

@property (nonatomic, strong) UIColor *backgroundColor;
@property (nonatomic, strong) NSMutableArray *items;
@property (nonatomic, strong) NSString *title;
@property (nonatomic, strong) UIColor *titleColor;
@property (nonatomic, strong) UIFont *titleFont;

@end

TODO

Give the possibility to open a section clicking on the section itself instead of the icon
Give the possibility to open a section programmatically
