iOS - allow user to add Calendar Event with some fields filled in - ios

Question

Is it possible in Objective-C in xCode to open up the native iPhone "Add Event" calendar prompt with a couple of fields already filled in? For instance name, address and start/end date? If so, how?
This would allow the user to still change a couple of parameters: when does he want to be alerted, etc.
I have looked around but all I have found are methods to automatically add the event without the confirmation of the user.

Step 1
First take Calendar Permission
dispatch_async(dispatch_get_main_queue(), ^{
[self.eventManager.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
if(granted==NO)
{
BOOL permission=[[NSUserDefaults standardUserDefaults] boolForKey:#"CalendarPermissionAlert"];
if(permission==NO) {
kAppDelegateObject.eventManager.eventsAccessGranted=NO;
[[NSUserDefaults standardUserDefaults]setBool:YES forKey:#"CalendarPermissionAlert"];
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:#"Calendar Access is OFF"
message:kCalenderResetMessage
delegate:self
cancelButtonTitle:#"CANCEL"
otherButtonTitles:#"SETTING",nil];
[alert show];
alert.tag=101;
return ;
}
}
Step 2
//Add Event
-(void)addEventWithMessage:(NSString*)eventMessage withEventDate:(NSDate *)eventDate
EKEventStore *eventStore;
eventStore = [[EKEventStore alloc] init];
// Create a new event object.
EKEvent *event = [EKEvent eventWithEventStore: eventStore];
// Set the event title.
event.title = eventMessage;
// Set its calendar.
NSString *identifier=[[NSUserDefaults standardUserDefaults]objectForKey:#"calenderId"]; //your application id
// NSLog(#"cal identifier: %#",identifier);
event.calendar = [eventStore calendarWithIdentifier:identifier];
//set Alarm
NSTimeInterval secondsInOneHours = 1 * 60 * 60;
NSDate *dateOneHoursAhead = [eventDate dateByAddingTimeInterval:secondsInOneHours];
// Set the start and end dates to the event.
event.startDate = eventDate;
event.endDate = dateOneHoursAhead; //
NSError *error;
if ([eventStore saveEvent:event span:EKSpanFutureEvents commit:YES error:&error]) {
// NSLog(#"Event Added");
}
else{
// An error occurred, so log the error description.
// NSLog(#"%#", [error localizedDescription]);
}

Here is how I handled it...with EKEventEditViewController!
First:
#import EventKitUI;
At the very top of your .m file.
Then set the EKEventEditViewDelegate
Then, when you want to add the event, use the following method:
- (IBAction)addToCalendar:(id)sender {
EKEventStore *eventStore = [[EKEventStore alloc] init];
if ([eventStore respondsToSelector:#selector(requestAccessToEntityType:completion:)])
{
// the selector is available, so we must be on iOS 6 or newer
[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
if (error)
{
NSLog(#"%#", error);
// display error message here
}
else if (!granted)
{
NSLog(#"%# acce sdenied", error);
// display access denied error message here
}
else
{
EKEvent *event = [EKEvent eventWithEventStore: eventStore];
event.title = nom;
event.location = adresse;
// Set the start and end dates to the event.
event.startDate = startDate;
event.endDate = endDate; //
EKEventEditViewController *eventViewController = [[EKEventEditViewController alloc] init];
eventViewController.event = event;
eventViewController.eventStore=eventStore;
eventViewController.editViewDelegate = self;
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
[eventViewController setModalPresentationStyle:UIModalPresentationFullScreen];
[self presentViewController:eventViewController animated:YES completion:NULL];
}
});
}];
}
}
Finally, add this delegate method to handle the completion action:
-(void)eventEditViewController:(EKEventEditViewController *)controller
didCompleteWithAction:(EKEventEditViewAction)action {
NSError *error;
switch (action) {
case EKEventEditViewActionCancelled:
// User tapped "cancel"
NSLog(#"Canceled");
break;
case EKEventEditViewActionSaved:
NSLog(#"Saved");
[controller.eventStore saveEvent:controller.event span: EKSpanFutureEvents error:&error];
[calendarBouton setTitle:#"Ajouté!" forState:UIControlStateDisabled];
calendarBouton.enabled = NO;
break;
case EKEventEditViewActionDeleted:
// User tapped "delete"
NSLog(#"Deleted");
break;
default:
NSLog(#"Default");
break;
}
[self dismissViewControllerAnimated:YES completion:nil];
}
