Installation

CocoaPods:

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

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

NSCalendarExtension is required to get iOS7 compatibility.

Carthage:

github "WenchaoD/FSCalendar"

SPM:

Add dependency:

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

Manually:

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

fscalendar-ib

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

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

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

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

- (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];
}

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()
}

Pre-knowledge

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

How to create NSDate object

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

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

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];

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];
...

NSDate *nextMonth = [self.gregorain dateByAddingUnit:NSCalendarUnitMonth value:1 toDate:date options:0];

NSDate *nextDay = [self.gregorain dateByAddingUnit:NSCalendarUnitDay value:1 toDate:date options:0];

BOOL isToday = [self.gregorian isDateInToday:date];
BOOL isYesterday = [self.gregorian isDateInYesterday:date];
BOOL isTomorrow = [self.gregorian isDateInTomorrow:date];
BOOL isWeekend = [self.gregorian isDateInWeekend:date];


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

FSCalendar
What is this?FSCalendar is a fully customizable calendar UI library for iOS, usable from both Objective-C and Swift.
Is this a ready-made calendar app, or code I add to my own Xcode project?It's a library, not an app: a UIView subclass you drop into your own screens and drive through its dataSource and delegate.
How do I get it into my app?Install via CocoaPods (recommended for iOS 8+), Carthage or SPM, or drag the FSCalendar source files into your project; then set a UIView's custom class to FSCalendar and implement its protocols.
Which iOS versions does it run on?iOS 8 and up for the CocoaPods, Carthage and SPM installs; iOS 7 is still reachable via CocoaPods if you enable NSCalendarExtension.
Will the calendar lay itself out, or is there a catch?There's a catch: it never updates its own frame, so you implement the layout yourself — AutoLayout constraints, manual layout, or helpers if you use Masonry or SnapKit.
Can I use it in my own app, including a commercial one?Yes — it's MIT licensed, so commercial use is fine; the author only asks for a star and a screenshot shout-out on Twitter if you build something nice.
I'm writing my app in Swift — anything special about using it?Yes: create a bridging header first. An Example-Swift project ships with the repo showing the full setup, including Swift 3 renames like Date and DateFormatter.
How customizable is it, really?Fully: you can supply your own date cells (a DIY example ships in both Example-Swift and Example-Objc), and the demo covers single-selection, multiple-selection and DIY swipe-to-choose.
Where can it show up beyond a plain iPhone screen?The README shows it on iPhone and iPad, through safe-orientation changes, and even embedded in an iOS 8/9/10 Today widget extension.
Can I try it before integrating it?Yes — open the Example-Objc or Example-Swift project and press command+u to launch the UITest target.
What are similar projects?SkeletonView, Spring, SVProgressHUD, AFNetworking, Eureka, AsyncDisplayKit, chameleon, SwiftyJSON
Which topics is it in?carthage, swift-package-manager, uikit, calendar, cocoapods, widget, objective-c, xcode, mobile-development, apple, swift, ui-components
