Installation

CocoaPods:

• For iOS8+: 👍

use_frameworks!
target '<Your Target Name>' do
    pod 'FSCalendar'
end

• For iOS7+:

target '<Your Target Name>' do
	pod 'FSCalendar'
end

NSCalendarExtension is required to get iOS7 compatibility.

Carthage:

• For iOS8+

github "WenchaoD/FSCalendar"

SPM:

Add dependency:

.package(url: "https://github.com/WenchaoD/FSCalendar.git", from: "2.8.4")

Manually:

• Drag all files under FSCalendar folder into your project. 👍

Alternatively to give it a test run, simply press command+u in Example-Objc or Example-Swift and launch the UITest Target.
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

4、 Finally, implement FSCalendarDataSource and FSCalendarDelegate in your ViewController

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

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

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 update frame by itself, Please implement

• For AutoLayout

- (void)calendar:(FSCalendar *)calendar boundingRectWillChange:(CGRect)bounds animated:(BOOL)animated
{
    self.calendarHeightConstraint.constant = CGRectGetHeight(bounds);
    // Do other updates here
    [self.view layoutIfNeeded];
}

• For Manual Layout

- (void)calendar:(FSCalendar *)calendar boundingRectWillChange:(CGRect)bounds animated:(BOOL)animated
{
    calendar.frame = (CGRect){calendar.frame.origin,bounds.size};
    // Do other updates here
}

• If you are using Masonry

- (void)calendar:(FSCalendar *)calendar boundingRectWillChange:(CGRect)bounds animated:(BOOL)animated
{
    [calendar mas_updateConstraints:^(MASConstraintMaker *make) {
        make.height.equalTo(@(bounds.size.height));
        // Do other updates
    }];
    [self.view layoutIfNeeded];
}

• If you are using SnapKit

func calendar(_ calendar: FSCalendar, boundingRectWillChange bounds: CGRect, animated: Bool) {
    calendar.snp.updateConstraints { (make) in
        make.height.equalTo(bounds.height)
        // Do other updates
    }
    self.view.layoutIfNeeded()
}

Roll with Interface Builder

Pre-knowledge

In Swift3, NSDate and NSDateFormatter have been renamed to Date and DateFormatter , see Example-Swift 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
