Support IBInspectable / IBDesignable

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

Setup

Use Interface Builder

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

fscalendar-ib

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

Or use code

@property (weak , nonatomic) FSCalendar *calendar;
// In loadView(Recommended) 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

fileprivate 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

To use FSCalendar in Swift3, see Example-Swift for details.


Warning

FSCalendar doesn't change frame by itself, Please implement

  • For autoLayout
- (void)calendar:(FSCalendar *)calendar boundingRectWillChange:(CGRect)bounds animated:(BOOL)animated
{
    _calendarHeightConstraint.constant = CGRectGetHeight(bounds);
    [self.view layoutIfNeeded];
}
  • For manual layout
- (void)calendar:(FSCalendar *)calendar boundingRectWillChange:(CGRect)bounds animated:(BOOL)animated
{
    calendar.frame = (CGRect){calendar.frame.origin,bounds.size};
}

Roll with Interface Builder

Pre-knowledge

In Swift3, NSDate and NSDateFormatter have been renamed to Date and DateFormatter , see SwiftExample for details.

How to create NSDate object

  • By NSCalendar.
self.gregorian = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];

Then:

NSDate *date = [gregorian dateWithEra:1 year:2016 month:9 day:10 hour:0 minute:0 second:0 nanosecond:0];
// 2016-09-10 00:00:00
  • Or by NSDateFormatter
self.formatter = [[NSDateFormatter alloc] init];
self.formatter.dateFormat = @"yyyy-MM-dd";

Then:

NSDate *date = [self.formatter dateFromString:@"2016-09-10"];

How to print out NSDate object

  • Use NSDateFormatter
self.formatter = [[NSDateFormatter alloc] init];
self.formatter.dateFormat = @"yyyy/MM/dd";
NSString *string = [self.formatter stringFromDate:date];
NSLog(@"Date is %@", string);

How to manipulate NSDate with NSCalendar

self.gregorian = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];
  • Get component of NSDate
NSInteger era = [self.gregorian component:NSCalendarUnitEra fromDate:date];
NSInteger year = [self.gregorian component:NSCalendarUnitYear fromDate:date];
NSInteger month = [self.gregorian component:NSCalendarUnitMonth fromDate:date];
NSInteger day = [self.gregorian component:NSCalendarUnitDay fromDate:date];
NSInteger hour = [self.gregorian component:NSCalendarUnitHour fromDate:date];
NSInteger minute = [self.gregorian component:NSCalendarUnitMinute fromDate:date];
...
  • Get next month
NSDate *nextMonth = [self.gregorain dateByAddingUnit:NSCalendarUnitMonth value:1 toDate:date options:0];
  • Get next day
NSDate *nextDay = [self.gregorain dateByAddingUnit:NSCalendarUnitDay value:1 toDate:date options:0];
  • Is date in today/tomorrow/yesterday/weekend
BOOL isToday = [self.gregorian isDateInToday:date];
BOOL isYesterday = [self.gregorian isDateInYesterday:date];
BOOL isTomorrow = [self.gregorian isDateInTomorrow:date];
BOOL isWeekend = [self.gregorian isDateInWeekend:date];
  • Compare two dates
BOOL sameDay = [self.gregorian isDate:date1 inSameDayAsDate:date2];
// Yes if the date1 and date2 are in same day


[self.gregorian compareDate:date1 toDate:date2 toUnitGranularity:unit];
// compare the era/year/month/day/hour/minute .etc ...
// return NSOrderAscending/NSOrderSame/NSOrderDecending

BOOL inSameUnit = [self.gregorian isDate:date1 equalToDate:date2 toUnitGranularity:unit];
// if the given unit (era/year/month/day/hour/minute .etc) are the same
