Hey Daan, 

Thanks for the sample. 

The Calendar is actually working correctly. However, when the WeekView request the appointments, there aren't any appointments available yet. 

Thats b/c in the sample, the appointments from the CSV are being loaded in a background thread. 

So when the calendar asks for appointments for that specific point in time, there are no appointments available. 

If you don't load the CSV in the background, then it works fine. Or you could call invalidate after the appointments are loaded and reloaded the calendar view. 

Hope this helps,

-SteveZ

Thanks for the reply Steve,

Maybe i'm doing something wrong in the way I set it up in my project. We are using AFNetworking to retrieve the data from a web service. Let me summarize what i've done:

-(void)calendarView:(IGCalendarView *)calView asyncAppointmentRequest:(IGCalendarAppointmentRequest *)request ofType:(IGCalendarAppointmentRequestType)requestType

{

// Guess I can remove the following since the -001 bug has been fixed in the service release :-)

    unsigned int flags = NSCalendarUnitYear | NSCalendarUnitMonth;

    NSCalendar* calendar = [NSCalendar currentCalendar];

    NSDateComponents* components = [calendar components:flags fromDate:request.start];

    if (components.year < 1970)

    {

        NSLog(@"Year is really low.");

        return;

    }

    // I am keeping record of every month being retrieved at the web service so that I don't get the appointments more than once.

    NSDate* strippedRequestDate = [calendar dateFromComponents:components];

    bool monthExists;

    for (NSDate * date in months)

    {

        if ([date timeIntervalSince1970] == [[strippedRequestDate toFirstDayOfMonth] timeIntervalSince1970])

            monthExists = true;

    }

// When the month exists, filter the list of appointments and return the requested ones    

    if (monthExists)

    {

        [[[NSOperationQueue alloc]init] addOperation:[NSBlockOperation blockOperationWithBlock:^(void)

                                                      {

                                                          NSLog(@"request.start %@", request.start);

                                                          NSLog(@"request.end %@", request.end);

                                                          NSTimeInterval min = [request.start timeIntervalSince1970];

                                                          NSTimeInterval max = [request.end timeIntervalSince1970];

                                                          NSMutableArray* returnAppts = [[NSMutableArray alloc]init];

                                                          for (IGCalendarAppointment* appt in _appts)

                                                          {

                                                              NSTimeInterval current = [appt.startTime timeIntervalSince1970];

                                                              if(current >= min && current <= max)

                                                                  [returnAppts addObject:appt];

                                                          }

                                                          [[NSOperationQueue mainQueue] addOperation: [NSBlockOperation blockOperationWithBlock:^(void)

                                                                                                   {

                                                                                                       NSArray* appts = [NSArray arrayWithArray:returnAppts];

                                                                                                       NSLog(@"APPOINTMENT COUNT: %lu", (unsigned long)appts.count);

//                                                                                                       [request provideAppointments:appts];

                                                                                                   }]];

                                                      }]];

    }

    else

    {

// Custom method converting the date to first day of month and stripping hour, minute and second information

        [months addObject:[strippedRequestDate toFirstDayOfMonth]]; 

    // Following does the AFNetworking call to the web service, when it's done it provides the appointments so this is not exactly the same as the CSV example because the data is already retrieved.

        PostParameters * params = [[PostParameters alloc] init];

        [params.params setObject:[NSDate dateToServerStr:[strippedRequestDate toFirstDayOfMonth]] forKey:@"startdate"];

        [params.params setObject:[NSDate dateToServerStr:[strippedRequestDate toLastDayOfMonth]] forKey:@"enddate"];

        Networking * networking = [Networking networking];

        [networking postRequest:params action:@"GetCalendarAppointments" success:^(NSString * xmlResponse) {

            [_appts addObjectsFromArray:[[Context sharedContext].webservice getCalendarAppointments:xmlResponse]];

            [[[NSOperationQueue alloc]init] addOperation:[NSBlockOperation blockOperationWithBlock:^(void)

                                                          {

                                                              NSLog(@"request.start = %@", request.start);

                                                              NSLog(@"request.end = %@", request.end);

                                                              NSTimeInterval min = [request.start timeIntervalSince1970];

                                                              NSTimeInterval max = [request.end timeIntervalSince1970];

                                                              NSMutableArray* returnAppts = [[NSMutableArray alloc]init];

                                                              for (IGCalendarAppointment* appt in _appts)

                                                              {

                                                                  NSTimeInterval current = [appt.startTime timeIntervalSince1970];

                                                                  if(current >= min && current <= max)

                                                                      [returnAppts addObject:appt];

                                                              }

                                                              [[NSOperationQueue mainQueue] addOperation: [NSBlockOperation blockOperationWithBlock:^(void)

                                                                                                           {

                                                                                                               NSArray* appts = [NSArray arrayWithArray:returnAppts];

                                                                                                           NSLog(@"APPOINTMENT COUNT: %lu", (unsigned long)appts.count);

                                                                                                               [request provideAppointments:appts];

                                                                                                           }]];

                                                          }]];

            NSLog(@"Success!");

        } failure:^(NSError * error) {

            NSLog(@"FAILED ACTION");

// If the web service fails, remove the added month from the months list so we can retrieve it again. Never got this message so this is not it.

            [months removeObject:strippedRequestDate];

        }];

    }

}

I have found a fix but I don't think it's a nice one (calendar flickers a lot and horizontal scrolling through weeks is very buggy with this implemented)

Added a boolean forceRefresh to the class.

When monthExists is true in the code from my previous post I set the boolean to true right [request provideAppointments:appts]; with the following code:

if (appts.count == 0)
   forceRefresh = true;

When the month doesn't exist (the else statement in previous post) I add the following code right after the [request proviceAppointments:appts];

if (forceRefresh)
{
   [_calendar invalidate];
   forceRefresh = false;
}

Well.. The data does show up this way and that is important for now.

Hope to hear from you if this is the solution to go with or if there are other ways of implementing a better solution.

Hey Daan, 

Ok, so its definitely using the same build. 

Maybe you can try using Sync callback with your simplified sample, and see if thats getting called 4 times?

Perhaps the projects are using different versions of the IG Framework?

Can you insert the following line of code, in both the sample application, and in your actual app?

NSLog(@"%@", [IGBuildVersion buildVersion]);

I just want to make sure that your application isn't holding on to an older version. 

-SteveZ

I see the sample and everything working fine there. The only other difference I see is that you are using a storyboard where as we're using seperate xib files for the user interface.

I'm running out of ideas and without the CalendarView source code there is no way I can debug the issue. As you saw I stripped the entire code and do a simple call to the UIViewController. Nothing special just like in your sample.

Therefore I also checked the project settings and made some changes there. Also no result.

Hey Daan, 

Thanks for the stripped down version. 

I tried it out, and cleaned out all the commented code, but its still not happening for me. 

I've attached the sample. Can you verify your'e seeing the same thing?
