# <a id="installation"></a>Installation
## CocoaPods:
* For iOS8+: 👍
```ruby
use_frameworks!
target '<Your Target Name>' do
pod 'FSCalendar'
end
```
* For iOS7+:
```ruby
target '<Your Target Name>' do
pod 'FSCalendar'
end
```
> [NSCalendarExtension](https://github.com/WenchaoD/NSCalendarExtension) is required to get iOS7 compatibility.
## Carthage:
* For iOS8+
```ruby
github "WenchaoD/FSCalendar"
```
## SPM:
Add dependency:
```swift
.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***. <br>
> Only the methods marked "👍" support IBInspectable / IBDesignable feature. [Have fun with Interface builder](#roll_with_interface_builder)
# Setup
## Use Interface Builder
1、 Drag an UIView object to ViewController Scene
2、 Change the `Custom Class` to `FSCalendar`<br/>
3、 Link `dataSource` and `delegate` to the ViewController <br/>
4、 Finally, implement `FSCalendarDataSource` and `FSCalendarDelegate` in your `ViewController`
## Or use code
```objc
@property (weak , nonatomic) FSCalendar *calendar;
```
```objc
// 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;
```
<br/>
## Or swift
* To use `FSCalendar` in swift, you need to [Create Bridge Header](https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html) first.
```swift
fileprivate weak var calendar: FSCalendar!
```
```swift
// 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.
## <a id='adjusts_frame_dynamicly' /></a>Warning
`FSCalendar` ***doesn't*** update frame by itself, Please implement
* For ***AutoLayout***
```objc
- (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***
```objc
- (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***
```objc
- (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***
```swift
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()
}
```

> In `Swift3`, `NSDate` and `NSDateFormatter` have been renamed to ***Date*** and ***DateFormatter*** , see `Example-Swift` for details.
## How to create NSDate object
* By **NSCalendar**.
```objc
self.gregorian = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];
```
Then:
```objc
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**
```objc
self.formatter = [[NSDateFormatter alloc] init];
self.formatter.dateFormat = @"yyyy-MM-dd";
```
Then:
```objc
NSDate *date = [self.formatter dateFromString:@"2016-09-10"];
```
## How to print out NSDate object
* Use **NSDateFormatter**
```objc
self.formatter = [[NSDateFormatter alloc] init];
self.formatter.dateFormat = @"yyyy/MM/dd";
```
```objc
NSString *string = [self.formatter stringFromDate:date];
NSLog(@"Date is %@", string);
```
## How to manipulate NSDate with NSCalendar
```objc
self.gregorian = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];
```
* Get component of NSDate
```objc
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**
```objc
NSDate *nextMonth = [self.gregorain dateByAddingUnit:NSCalendarUnitMonth value:1 toDate:date options:0];
```
* Get next **day**
```objc
NSDate *nextDay = [self.gregorain dateByAddingUnit:NSCalendarUnitDay value:1 toDate:date options:0];
```
* Is date in today/tomorrow/yesterday/weekend
```objc
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
```objc
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
```
