UITableView with sections - iphone

Question

I have an app and in one view is a table. In the table I call the EventStore So It fills the table with your calendar events. I would like to have bars in the table like the ical app on the iphone so It breaks the days up with A bar the bar has the date (ex. March 25, 2011). Below is the code for the table
//eventsTable.h
#import <UIKit/UIKit.h>
#import <EventKit/EventKit.h>
#import <EventKitUI/EventKitUI.h>
#interface eventsTable : UIViewController <UITableViewDelegate, UITableViewDataSource, UIAlertViewDelegate,UIPopoverControllerDelegate,UINavigationControllerDelegate> {
IBOutlet UITableView *Table;
EKEventStore *eventStore;
EKEvent *event;
EKEventViewController *detailViewController;
EKCalendar *defaultCalendar;
NSMutableArray *eventsList;
}
-(IBAction) done;
- (NSArray *)fetchEventsForToday;
#property (nonatomic, retain)
IBOutlet UITableView *Table;
#property (nonatomic, retain) EKEventStore *eventStore;
#property (nonatomic, retain) EKCalendar *defaultCalendar;
#property (nonatomic, retain) NSMutableArray *eventsList;
#property (nonatomic, retain) EKEventViewController *detailViewController;
#end
//eventsTable.m
#import "eventsTable.h"
#implementation eventsTable
#synthesize eventsList, eventStore, defaultCalendar, detailViewController,Table;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
self.title = #"Events List";
// Initialize an event store object with the init method. Initilize the array for events.
self.eventStore = [[EKEventStore alloc] init];
self.eventsList = [[NSMutableArray alloc] initWithArray:0];
// Get the default calendar from store.
self.defaultCalendar = [self.eventStore defaultCalendarForNewEvents];
// Create an Add button
// Fetch today's event on selected calendar and put them into the eventsList array
[self.eventsList addObjectsFromArray:[self fetchEventsForToday]];
[Table reloadData];
}
-(IBAction) done{
[self dismissModalViewControllerAnimated:YES];
}
#pragma mark -
#pragma mark Table view data source
// Fetching events happening in the next 24 hours with a predicate, limiting to the default calendar
- (NSArray *)fetchEventsForToday {
NSDate *startDate1 = [NSDate date];
// endDate is 1 day = 60*60*24 seconds = 86400 seconds from startDate
NSDate *endDate1 = [NSDate distantFuture];
// Create the predicate. Pass it the default calendar.
NSArray *calendarArray = [NSArray arrayWithObject:defaultCalendar];
//NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate endDate:endDate

Answer 1

You are going to have to split each day up into a separate section and implement the proper UITableViewDataSource protocols for section indexes: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewDataSource_Protocol/Reference/Reference.html
Here is a tutorial: http://www.iphonedevcentral.com/indexed-uitableview-tutorial/

Answer 2

If I understand your question correctly, you need to change the section titles with the date you want to display. You do this by implementing the (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section method.

Answer 3

You have a problem in your code despite the question. You must release the resources before the return.
return(result);
[event release];
[eventsList release];
[eventStore release];
[result release];
