Presenting Calendar Views

#import <UIKit/UIKit.h>
#import "MAFCalendarView.h"

@interface RootViewController : UIViewController<MAFCalendarViewDataSource,MAFCalendarViewDelegate>
{
}

After declaring that your UIViewController provides implementation for both interfaces, implement getAppointmentsFromStart:toEnd: from the MAFCalendarViewDatasource protocol. This code iterates through the NSArray of Appointments stored in the view controller, and filters the appointments with the help of NSDate+MAFExtensions class by the start and end dates received from of the MAFCalendarView.

-(BOOL) isDate:(NSDate*)date withinStart:(NSDate*)startDate andEnd:(NSDate*)endDate
{
    return [date isWithinStart:startDate andEnd:(NSDate*)endDate];
}

-(NSArray *)calendarView:(MAFCalendarView *)sender getAppointmentsFromStart:(NSDate *)start toEnd:(NSDate *)end
{
    // please note this data source is for demo purposes only
    
    NSMutableArray* ret = [[[NSMutableArray alloc] init] autorelease];
    
    for(MAFAppointment* app in arr)
    {
        if([self isDate:app.startDate withinStart:start andEnd:end])
            [ret addObject:app];
    }
    
    return ret;
}

Provide the MAFAppointment data source implementation. for your own use case. MAFCalendarViewDelegate contains only optional methods. You can implement these methods to be notified about events of appointments and calendar views. This is example code to create MAFAppointment data from code:

-(void)createData
{
    arr = [[NSMutableArray alloc] init];
    
    // Convert string to date object
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"Europe/Berlin"]];
    [dateFormat setDateFormat:@"dd-MM-yyyy HH:mm"];
    
    MAFCalendar* cal = [[[MAFCalendar alloc] init] autorelease];
    cal.name = @"First Calendar";
    cal.color       = [UIColor colorWithRed:177/255.0f green:211/255.0f blue:74/255.0f alpha:1.0];
    cal.bordercolor = [UIColor colorWithRed:0/255.0f green:138/255.0f blue:59/255.0f alpha:1.0];
    
    MAFCalendar* cal2 = [[[MAFCalendar alloc] init] autorelease];
    cal2.name = @"Second Calendar";
    cal2.color      = [UIColor colorWithRed:0/255.0f green:161/255.0f blue:228/255.0f alpha:1.0];
    cal2.bordercolor = [UIColor colorWithRed:0/255.0f green:116/255.0f blue:187/255.0f alpha:1.0];
    
    
    MAFCalendar* cal3 = [[[MAFCalendar alloc] init] autorelease];
    cal3.name = @"Third Calendar";
    cal3.color        = [UIColor colorWithRed:246/255.0f green:139/255.0f blue:31/255.0f alpha:1.0];
    cal3.bordercolor  = [UIColor colorWithRed:203/255.0f green:77/255.0f blue:44/255.0f alpha:1.0];
    
    
    NSDate* today = [NSDate date];
    today = [NSDate toDayBoundaryFloor:today withTimeZone:[NSTimeZone localTimeZone]];
    
    NSTimeInterval d = 60*60*24;
    MAFAppointment* app = [[[MAFAppointment alloc] init] autorelease];
    app.startDate = [NSDate dateWithTimeInterval:10*60*60.0+d sinceDate:today];
    app.endDate = [NSDate dateWithTimeInterval:11*60*60.0+d sinceDate:today];
    app.title    = @"Meeting 2204";
    app.location = @"Walldorf";
    app.notes    = @"notes";
    app.calendar = cal;
    
    [arr addObject:app];
    
    app = [[[MAFAppointment alloc] init] autorelease];
    app.startDate = [NSDate dateWithTimeInterval:12*60*60.0+d sinceDate:today];
    app.endDate = [NSDate dateWithTimeInterval:13*60*60.0+d sinceDate:today];
    app.title    = @"Lunch";
    app.location = @"Walldorf";
    app.notes    = @"notes";
    app.calendar = cal2;
    
    [arr addObject:app];
    
    app = [[[MAFAppointment alloc] init] autorelease];
    app.startDate = [NSDate dateWithTimeInterval:11*60*60.0+d sinceDate:today];
    app.endDate = [NSDate dateWithTimeInterval:14*60*60.0+d sinceDate:today];
    app.title    = @"Meeting 2";
    app.location = @"Walldorf";
    app.notes    = @"notes";
    app.calendar = cal3;
    
    
    [arr addObject:app];
}

You can now initialize and present your MAFAppointments on any of the MAFCalendarViews.
