Support IBInspectable / IBDesignable

Only the methods marked "👍" support IBInspectable / IBDesignable feature. Have fun with Interface builder

Setup

Use Interface Builder (Recommended)

1. Drag an UIView object to ViewController Scene
2. Change the Custom Class to FSCalendar
   
3. Link dataSource and delegate to the ViewController
   

4. Finally, you should implement FSCalendarDataSource and FSCalendarDelegate in ViewController.m

Code

@property (weak , nonatomic) FSCalendar *calendar;

// In loadView or viewDidLoad
FSCalendar *calendar = [[FSCalendar alloc] initWithFrame:CGRectMake(0, 0, 320, 300)];
calendar.dataSource = self;
calendar.delegate = self;
[self.view addSubview:calendar];
self.calendar = calendar;

Or swift

• To use FSCalendar in swift, you need to Create Bridge Header first.

private weak var calendar: FSCalendar!

// In loadView or viewDidLoad
let calendar = FSCalendar(frame: CGRect(x: 0, y: 0, width: 320, height: 300))
calendar.dataSource = self
calendar.delegate = self
view.addSubview(calendar)
self.calendar = calendar

More usage

If you want FSCalendar to scroll vertically

• Objective - c

_calendar.flow = FSCalendarFlowVertical;

• Swift

calendar.flow = .Vertical 

If you want FSCalendar to scroll horizontally (Default)

• Objective - c

_calendar.flow = FSCalendarFlowHorizontal; // By default

• Swift

calendar.flow = .Horizontal 

If you want FSCalendar to use Monday as the first column (or any other weekday)

_calendar.firstWeekday = 2; 

The date format of header can be customized

_calendar.appearance.headerDateFormat = @"MMM yy";

You can define the appearance

_calendar.appearance.weekdayTextColor = [UIColor redColor];
_calendar.appearance.headerTitleColor = [UIColor redColor];
_calendar.appearance.eventColor = [UIColor greenColor];
_calendar.appearance.selectionColor = [UIColor blueColor];
_calendar.appearance.todayColor = [UIColor orangeColor];
_calendar.appearance.todaySelectionColor = [UIColor blackColor];

The day shape doesn't have to be a circle

• Objective - c

_calendar.appearance.cellStyle = FSCalendarCellStyleRectangle;

• Swift

calendar.appearance.cellStyle = .Rectangle

FSCalendar can show subtitle for each day

• Objective - c

// FSCalendarDataSource
- (NSString *)calendar:(FSCalendar *)calendar subtitleForDate:(NSDate *)date
{
    return yourSubtitle;
}

• Swift

// FSCalendarDataSource
func calendar(calendar: FSCalendar!, subtitleForDate date: NSDate!) -> String! {
    return yourSubtitle
}

And event dot for some days

• Objective - c

// FSCalendarDataSource
- (BOOL)calendar:(FSCalendar *)calendar hasEventForDate:(NSDate *)date
{
    return shouldShowEventDot;
}

• Swift

// FSCalendarDataSource
func calendar(calendar: FSCalendar!, hasEventForDate date: NSDate!) -> Bool {
    return shouldShowEventDot
}

Or image for some days

• Objective - c

// FSCalendarDataSource
- (UIImage *)calendar:(FSCalendar *)calendar imageForDate:(NSDate *)date
{
    return anyImage;
}

• Swift

// FSCalendarDataSource
func calendar(calendar: FSCalendar!, imageForDate date: NSDate!) -> UIImage! {
    return anyImage
}

There are left and right boundaries

// FSCalendarDataSource
- (NSDate *)minimumDateForCalendar:(FSCalendar *)calendar
{
    return yourMinimumDate;
}

- (NSDate *)maximumDateForCalendar:(FSCalendar *)calendar
{
    return yourMaximumDate;
}

You can do something when a date is selected

• Objective - c

// FSCalendarDelegate
- (void)calendar:(FSCalendar *)calendar didSelectDate:(NSDate *)date
{
    // Do something
}

• Swift

// FSCalendarDelegate
func calendar(calendar: FSCalendar!, didSelectDate date: NSDate!) {
    
}

You can prevent it from being selected

• Objective - c

// FSCalendarDelegate
- (BOOL)calendar:(FSCalendar *)calendar shouldSelectDate:(NSDate *)date
{
    if ([dateShouldNotBeSelected]) {
        return NO;
    }
    return YES;
}

• Swift

func calendar(calendar: FSCalendar!, shouldSelectDate date: NSDate!) -> Bool {
    if dateShouldNotBeSelected {
        return false
    }
    return true
}

You will get notified when FSCalendar changes the month

• Objective - c

- (void)calendarCurrentMonthDidChange:(FSCalendar *)calendar
{
    // Do something
}

• Swift

func calendarCurrentMonthDidChange(calendar: FSCalendar!) {
    // Do something
}

FSCalendar can be used on iPad.

Roll with Interface Builder

• fakeSubtitles and fakedSelectedDay is only used for preview in Interface Builder

Known issues

• The title size changed as we change frame size of FSCalendar: Automatically adjusting font size based on frame size is default behavior of FSCalendadr, to disable it:

_calendar.appearance.autoAdjustTitleSize = NO; 
_calendar.appearance.titleFont = otherTitleFont;
_calendar.appearance.subtitleFont = otherSubtitleFont;

titleFont and subtitleFont would not take any effect if autoAdjustTitleSize value is YES

• What if I don't need the today circle?

_calendar.appearance.todayColor = [UIColor clearColor];
_calendar.appearance.titleTodayColor = _calendar.appearance.titleDefaultColor;
_calendar.appearance.subtitleTodayColor = _calendar.appearance.subtitleDefaultColor;

• Can we hide this?

_calendar.appearance.headerMinimumDissolvedAlpha = 0.0;
