Introduction
ios-calendar is a stylable month calendar view for use in iPhone applications.
It has two branches:
three20uses Three20 framework for stylingmasterallows you customize it without using Three20. It uses Nimbus, so it’s good idea to use Nimbus CSS for styling.
Note that README right now is a bit out of date and applies mostly to three20 branch, however the demo and tests are up-to-date.
While there are existing implementations (Kal and TKCalendarMonthView from Tapku Library, they are quite limited. In particular they both replicate styling and functionality of iPhone Calendar app and there is basically no easy way to adjust them. In addition to this – only portrait view is supported in them.
ios-calenar was developed to solve aforementioned problems. It’s default design is heavily inspired by MoMa iPhone app.
I maintain a list of apps using ios-calendar, feel free to add your app to it.
Project setup
While not elegant at all, currently the best method to add ios-calendar to your project is just to drop its source code in it (from “Calendar” group).
It is possible to use it as dependency, but only when your project doesn’t itself use Three20. Otherwise build results in XCode crash. I’m looking for suggestions on how better to resolve this issue.
Usage sample
XCode project on GitHub contains sample target – CalendarDemo. Here are main highlights:
CalendarDemoViewController.m
#import "CalendarDemoViewController.h"
#import <Three20UICommon/Three20UICommon+Additions.h>
@implementation CalendarDemoViewController
@synthesize calendarView;
- (void) loadView {
[super loadView];
self.calendarView = [[CXCalendarView new] autorelease];
[self.view addSubview: self.calendarView];
self.calendarView.frame = self.view.bounds;
self.calendarView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.calendarView.selectedDate = [NSDate date];
self.calendarView.delegate = self;
}
- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) interfaceOrientation {
return YES;
}
#pragma mark CXCalendarViewDelegate
- (void) calendarView: (CXCalendarView *) calendarView
didSelectDate: (NSDate *) date {
NSLog(@"Selected date: %@", date);
TTAlert([NSString stringWithFormat: @"Selected date: %@", date]);
}
@endCalendarDemoAppDelegate.m
There is one very important thing to do in app delegate – set up Three20 styling. There is sample stylesheet (inspired by MoMA) – TestStyleSheet.
#import "CalendarDemoAppDelegate.h"
#import "TestStyleSheet.h"
#import "CalendarDemoViewController.h"
@implementation CalendarDemoAppDelegate
@synthesize window = _window;
@synthesize viewController = _viewController;
- (BOOL) application: (UIApplication *) application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions {
[TTStyleSheet setGlobalStyleSheet: [[TestStyleSheet new] autorelease]];
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[CalendarDemoViewController alloc] init];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
@endStyling
Here’s default stylesheet for you to study:
#import "TestStyleSheet.h"
@implementation TestStyleSheet
- (TTStyle *) calendarCellStyle: (UIControlState) state {
if (state & UIControlStateDisabled) {
return [TTTextStyle styleWithColor: [UIColor clearColor] next: nil];
}
if (state & UIControlStateSelected) {
return [TTSolidFillStyle styleWithColor: [UIColor grayColor] next:
[TTTextStyle styleWithColor: [UIColor whiteColor] next: nil]];
}
return [TTTextStyle styleWithColor: [UIColor grayColor] next: nil];
}
- (TTStyle *) calendarMonthBarStyle {
return
[TTLinearGradientFillStyle styleWithColor1: RGBCOLOR(188, 200, 215)
color2: RGBCOLOR(125, 150, 179) next:
[TTFourBorderStyle styleWithTop: RGBCOLOR(213, 221, 230)
right: nil
bottom: RGBCOLOR(57, 70, 84)
left: nil
width: 1 next: nil]];
}
- (TTStyle *) calendarMonthBackButton: (UIControlState) state {
return
[TTTextStyle styleWithFont: [UIFont systemFontOfSize: [UIFont buttonFontSize]]
color: [UIColor whiteColor]
shadowColor: [UIColor grayColor]
shadowOffset: CGSizeMake(0, 1) next: nil];
}
- (TTStyle *) calendarMonthForwardButton: (UIControlState) state {
return
[TTTextStyle styleWithFont: [UIFont systemFontOfSize: [UIFont buttonFontSize]]
color: [UIColor whiteColor]
shadowColor: [UIColor grayColor]
shadowOffset: CGSizeMake(0, 1) next: nil];
}
- (TTStyle *) calendarMonthLabelStyle {
return
[TTTextStyle styleWithFont: [UIFont systemFontOfSize: [UIFont buttonFontSize]]
color: [UIColor whiteColor]
shadowColor: [UIColor grayColor]
shadowOffset: CGSizeMake(0, 1) next: nil];
}
- (TTStyle *) calendarGridViewStyle {
return [TTSolidFillStyle styleWithColor: [UIColor whiteColor] next: nil];
}
