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
