The final iOS calendar control you'll ever try

Inspiration for this control was made possible by Michael @ Karmadust. Want to know how the calendar control works inside out? Check out his KDCalendar tutorial.

About Screenshots

Much like a UITableView, because you can design this calendar to look however you want, screenshots will not be an accurate depiction of what this control looks like, but you can check out what people have developed with this control and also post you own images at this link.. A sample iOS application is also included in this project's Github Repository to give you an idea of what you can do.

• Downloaded and liked this calendar's ease of use?
• Then don't forget to leave a ★ Star rating on Github. It's needed to make this control #1 :)
• Also, Support is not manditory, but will be much appreciated.

Installation using CocoaPods

CocoaPods is a dependency manager for Cocoa projects. Cocoapods can be installed with the following command:

$ gem install cocoapods

CocoaPods 0.39.0+ is required to build JTAppleCalendar

To integrate JTAppleCalendar into your Xcode project using CocoaPods, specify it in your Podfile:

platform :ios, '8.0'
use_frameworks!

pod 'JTAppleCalendar'

Then, run the following command at your project location:

$ pod install

The Problem

---

1. Apple has no calendar control.
2. Other calendar projects on Github try to cram every feature into their control, hoping it will meet the programmer's requirements.

This is an incorrect way to build controls. It leaves the developer with an extremely wide selection of (in many cases non-conventional) features that he has to sift through in order to configure the calendar. Also, no matter how wide the feature selection, the developer is always restricted to a predefined configuration-set shipped with the calendarControl. Do you see Apple building their UITableView by guessing what they think you want the UITableView to look like? No. So neither should we.

The Solution: JTAppleCalendar

Properties/functions/structs to help configure your calendar

The following structure was returned when a cell is about to be displayed.

    public enum DateOwner: Int {
        case ThisMonth = 0, PreviousMonthWithinBoundary, PreviousMonthOutsideBoundary, FollowingMonthWithinBoundary, FollowingMonthOutsideBoundary
    }

• .ThisMonth = the date to be displayed belongs to the month section
• .PreviousMonthWithinBoundary = date belongs to the previous month, and it is within the date boundary you set
• .PreviousMonthOutsideBoundary = date belongs to previous month, and it is outside the boundary you have set
• .FollowingMonthWithinBoundary = date belongs to following month, within boundary
• .FollowingMonthOutsideBoundary = date belongs to following month, outside boundary

    public func changeNumberOfRowsPerMonthTo(number: Int, withFocusDate date: NSDate?) // After switching the number of rows shown, pick a date to autofocus on
    public func reloadData()
    public func scrollToNextSegment(animateScroll: Bool = true, completionHandler:(()->Void)? = nil) 
    public func scrollToPreviousSegment(animateScroll: Bool = true, completionHandler:(()->Void)? = nil)
    public func scrollToDate(date: NSDate, animateScroll: Bool = true, completionHandler:(()->Void)? = nil)
    public func selectDates(dates: [NSDate], triggerSelectionDelegate: Bool = true)
    public func cellStatusForDateAtRow(row: Int, column: Int) -> CellState?

Properties you can configure

// Note: You do not need to configure your calendar with this if it is already the default
calendarView.direction = .Horizontal                       // default is horizontal
calendarView.numberOfRowsPerMonth = 6                      // default is 6
calendarView.cellInset = CGPoint(x: 0, y: 0)               // default is (3,3)
calendarView.allowsMultipleSelection = false               // default is false
calendarView.bufferTop = 0                                 // default is 0. - still work in progress
calendarView.bufferBottom = 0                              // default is 0. - still work in progress
calendarView.firstDayOfWeek = .Sunday                      // default is Sunday
calendarView.scrollEnabled = true                          // default is true
calendarView.pagingEnabled = true                          // default is true
calendarView.scrollResistance = 0.75                       // default is 0.75 - this is only applicable when paging is not enabled

Do you have any other questions?. If you are trying to bend heaven and earth to do something complicated with this calendar, then chances are there is already an easy way for it to be done. So Opening an issue might be a good idea.

Did you remember to leave a like? I would really appreciate it if you did.

Other functions/properties are coming. This is a very active project.
