问题

I want to add Event in my iPhone Calendar, i Successfully add the Event in my iPhone calendar. But, i want to get the all Current Month event and i want to attach that Event file (.ical) in my MFMailComposer.

回答1:

Reading events is very simple.

// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:startOfTheMonth
                                                        endDate:endOfTheMonth
                                                      calendars:nil];
// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];

More information in apple docs.

To get start and end of the month you can use example from this project: https://github.com/melsam/NSDateCategoryForReporting

And use this as an example how to export Events to .ical file https://github.com/mysterioustrousers/EKEventToiCal/blob/master/EKEventToiCal/

To send .ical file use the code from IronManGill answer but change mimeType to text/calendar

[picker addAttachmentData:data mimeType:@"text/calendar" fileName:@"/abc.ical"];

Well I can offer you a workaround. If you get the .ical file , have access to it. You could convert it into a .zip file , please go through these links :-

And then attach it alongwith the email in the MFMailComposer using this

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];    
NSString *WritableDBPath= [documentsDirectory stringByAppendingPathComponent:kFilename];    
NSData *data = [NSData dataWithContentsOfFile:WritableDBPath];    
[picker addAttachmentData:data mimeType:@"application/zip" fileName:@"/abc.zip"];
[picker setSubject:@"Database"];    
[picker setMessageBody:@"Database testing" isHTML:NO];    
[self presentModalViewController:picker animated:YES];

Hope this helps.
