i have this code which reads calendar data from the calendar app.
EKEventStore *store = [[EKEventStore alloc] init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted,
NSError *error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Import" message:#"Import Unavailable" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
}];
NSCalendar *calendar = [NSCalendar currentCalendar];
// Create the start date components
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day = -1;
NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents
toDate:[NSDate date]
options:0];
// Create the end date components
NSDateComponents *oneYearFromNowComponents = [[NSDateComponents alloc] init]; oneYearFromNowComponents.year = 1;
NSDate *oneYearFromNow = [calendar dateByAddingComponents:oneYearFromNowComponents
toDate:[NSDate date]
options:0];
// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:oneDayAgo
endDate:oneYearFromNow
calendars:nil];
// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];
for (id name in events)
NSLog (#"%#", name);
it logs full details of the result which outputs:
EKEvent <0x937c410>
{ title = Meeting w/ David;
location = (null);
calendar = EKCalendar <0x938a650> {title = Calendar; type = Local; allowsModify = YES; color = #1BADF8;};
alarms = (null);
URL = (null);
lastModified = 2014-03-27 11:52:39 +0000;
timeZone = Asia/Manila (GMT+8) offset 28800
};
location = (null);
startDate = 2014-03-28 04:00:00 +0000;
endDate = 2014-03-28 05:00:00 +0000;
allDay = 0;
floating = 0;
recurrence = (null);
attendees = (null)
};
what I want is, I only want to get start date, end date and location on 3 separate arrays..how do I get these?
BITTER BOYS :(
heres the answer to my question:
modified the last code to
NSArray *events = [store eventsMatchingPredicate:predicate];
for (id name in events){
NSString *theName = [name valueForKey:#"title"];
NSLog (#"%#", theName);
//NSLog (#"%#", name);
}

in my app I have a couple lines of code preparing a local notification for 7 am. The problem is that every time I close the app the notification will be showed. I only want this to happen ones after the set time is passed.
In my applicationDidEnterBackground:
NSCalendar *calendar = [NSCalendar currentCalendar]; // gets default calendar
NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]]; // gets the year, month, day,hour and minutesfor today's date
[components setHour:7];
UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notifyAlarm = [[UILocalNotification alloc] init];
if (notifyAlarm) {
notifyAlarm.fireDate = [calendar dateFromComponents:components];
notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
notifyAlarm.repeatInterval = 0;
notifyAlarm.soundName = #"not.wav";
notifyAlarm.alertBody = #"test";
[app scheduleLocalNotification:notifyAlarm];
}
In my applicationWillEnterForeground:
UIApplication *app = [UIApplication sharedApplication];
NSArray *oldNotifications = [app scheduledLocalNotifications];
if ([oldNotifications count] > 0) {
[app cancelAllLocalNotifications];
}
I think the problem is in the [oldNotifications count]. After implementing a NSLog to check it's amount it shows every time 0. This should count up, right?
Any help??? :)
try this code. if you want to repeat NSLocalNotification daily then you need to set repeatInterval to NSDayCalender unit.
NSCalendar *calendar = [NSCalendar currentCalendar]; // gets default calendar
NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]]; // gets the year, month, day,hour and minutesfor today's date
[components setHour:7];
UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notifyAlarm = [[UILocalNotification alloc] init];
if (notifyAlarm)
{
notifyAlarm.fireDate = [calendar dateFromComponents:components];
notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
notifyAlarm.repeatInterval = NSDayCalendarUnit;
notifyAlarm.soundName = #"not.wav";
notifyAlarm.alertBody = #"test";
[app scheduleLocalNotification:notifyAlarm];
}
I have added following code in my application.It is working fine if [comps setYear:1] but if i change year value to 2 or greater than 2 code does not show me any error but also not adding any event in calender. This happens in iOS 7 only. But if I run the same code on iOS 6 , its working correctly & event gets added in calender successfully. Is there any restriction in iOS 7 for adding future events ?

Whenever dealing with dates through components, please set them in the following fashion:
NSDateComponents *comps = [[[NSDateComponents alloc] init] autorelease];
[comps setDay:05];
[comps setMonth:01];
[comps setYear:2014]; //instead of adding a single digit number like so: 2
//followed by your code...
NSDate *sevenDays = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];
//...
UPDATE 1
You mentioned that your event is not being saved in the calendar when you slightly adjust the integer values in your NSDate's components. One quick way to see whats happening is by NSLogging your date. See what the ouput is before you try to add it to your calendar.
//Right after this below line
NSDate *sevenDays = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];
//Add the code here so we can see what `sevenDays` prints out.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:sevenDays];
NSLog(#"Seven Days date = %#", strDate);
Is there a way to get iOS' Local PushNotification to work on OSX? I have an program that I would like to receive scheduled notifications from the local computer even if the program is closed.
This is for local notification
- (void)scheduleNotificationWithItem:(ToDoItem *)item interval:(int)minutesBefore {
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
[dateComps setDay:item.day];
[dateComps setMonth:item.month];
[dateComps setYear:item.year];
[dateComps setHour:item.hour];
[dateComps setMinute:item.minute];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = [itemDate addTimeInterval:-(minutesBefore*60)];
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody =#"Local Notification";
localNotif.alertAction = NSLocalizedString(#"View Details", nil);
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:item.eventName forKey:ToDoItemKey];
localNotif.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
}

Below is my code. currently on a button click it opens up the calendar so the user can add events. How do I pass or preselect a date and title for the user when the event calendar opens up?
Heres my code.
-(IBAction) createEvent{
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEventEditViewController * controller =[[EKEventEditViewController alloc] init];
controller.eventStore = eventStore;
controller.editViewDelegate = self;
[self presentModalViewController: controller animated:YES]'
}
-(void) eventEditViewController:(EKEventEditViewController *) controller didCompleteWithAction:(EKEventEditViewAction)action{
[self dismissModalViewControllerAnimated:YES];
}
You need to assign an event to the EKEventEditViewController. You fill in your details into the event object.
EKEventStore *store = [[EKEventStore alloc] init];
EKEvent *event = [store eventWithIdentifier:#"some identifier"];
if(!event)
{
event = [EKEvent eventWithEventStore:store];
event.startDate = someDate;
event.endDate = someEndDate;
event.location = someLocationString;
event.availability = EKEventAvailabilityBusy;
event.title = #"Title here";
}
EKEventEditViewController *ekVC = [[EKEventEditViewController alloc] init];
ekVC.event = event;
ekVC.editViewDelegate = self;
[self presentModalViewController:ekVC animated:YES];
I would like to show the multiple selected dates in tapkilibrary .like highlight the dates between 14aug2011 to 18aug2011 .
-(NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate{

NSString *theTime = [timeFormat stringFromDate:date];
NSLog(#"%#",theTime);
objappdel.strdate=theTime;
[tkmonthView reload];
AppointmentDetail *appointmentDetail=[[AppointmentDetail alloc]initWithNibName:#"AppointmentDetail" bundle:nil];
[self.navigationController pushViewController:appointmentDetail animated:YES];
[appointmentDetail release];
}

{
NSMutableArray * data = [[NSMutableArray alloc] init];
NSDateFormatter *dateForm = [[NSDateFormatter alloc] init];
NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:#"GMT"];
[dateForm setDateFormat:#"yyyy-MM-dd"];

}

// Initialise empty marks array, this will be populated with TRUE/FALSE in order for each day a marker should be placed on.
NSMutableArray *marks = [NSMutableArray array];
// Initialise calendar to current type and set the timezone to never have daylight saving
NSCalendar *cal = [NSCalendar currentCalendar];
[cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
// Construct DateComponents based on startDate so the iterating date can be created.
// Its massively important to do this assigning via the NSCalendar and NSDateComponents because of daylight saving has been removed
// with the timezone that was set above. If you just used "startDate" directly (ie, NSDate *date = startDate;) as the first
// iterating date then times would go up and down based on daylight savings.
NSDateComponents *comp = [cal components:(NSYearCalendarUnit | NSMonthCalendarUnit |
NSDayCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit)
fromDate:startDate];
NSDate *d = [cal dateFromComponents:comp];
// Init offset components to increment days in the loop by one each time
NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
[offsetComponents setDay:1];
// for each date between start date and end date check if they exist in the data array
while (YES) {
// Is the date beyond the last date? If so, exit the loop.
// NSOrderedDescending = the left value is greater than the right
if ([d compare:lastDate] == NSOrderedDescending)
{
break;
}
// If the date is in the data array, add it to the marks array, else don't
//NSLog(#"%#",[d description]);
if ([data containsObject:[d description]]) {
[marks addObject:[NSNumber numberWithBool:YES]];
} else {
[marks addObject:[NSNumber numberWithBool:NO]];
}
// Increment day using offset components (ie, 1 day in this instance)
d = [cal dateByAddingComponents:offsetComponents toDate:d options:0];
}
[offsetComponents release];
return [NSArray arrayWithArray:marks];
}
Use this delegate method. It will return an NSArray of dates which you want to highlight.
You can do this by first entering the dates in to an array. code for this is.
- (void)calendarMonthView:(TKCalendarMonthView *)monthView didSelectDate:(NSDate *)d {
NSLog(#"selected Date IS - %#",inDate);
[myArray addObject:d];
for (id entry in myArray)
{
if (inDate == nil && outDate == nil)
{
inDate = d;
outDate = d;
}
if ([d compare:inDate] == NSOrderedAscending)
{
inDate = d;
}
if ([d compare:outDate] == NSOrderedDescending)
{
outDate = d;
}
d = nil;
}
}
After this you have to use a button click action by which you can make the dates selected between these two dates. Code for it is:
- (IBAction)goBtn:(id)sender
{
NSLog(#"startDate is: %#",inDate);
NSLog(#"endDate is: %#",outDate);
[calendar reload];
inDate = nil;
outDate = nil;
}
}
Then in one delegate method you just have to make an array containing all the dates between these two dates. It will be called just after the button click. Code for it is:
- (NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate {
//***********
NSMutableArray *tempData = [[NSMutableArray alloc] init];
NSDate *nextDate;
for ( nextDate = inDate ; [nextDate compare:outDate] < 0 ; nextDate = [nextDate addTimeInterval:24*60*60] ) {
// use date
NSLog(#"%#",nextDate);
[tempData addObject:[NSString stringWithFormat:#"%#",nextDate]];
}
[tempData addObject:[NSString stringWithFormat:#"%#",outDate]];
//***********
NSMutableArray *marks = [NSMutableArray array];
NSCalendar *cal = [NSCalendar currentCalendar];
[cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDateComponents *comp = [cal components:(NSMonthCalendarUnit | NSMinuteCalendarUnit | NSYearCalendarUnit |
NSDayCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSSecondCalendarUnit)
fromDate:startDate];
NSDate *d = [cal dateFromComponents:comp];
NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
[offsetComponents setDay:1];
while (YES) {
if ([d compare:lastDate] == NSOrderedDescending) {
break;
}
if ([tempData containsObject:[d description]]) {
[marks addObject:[NSNumber numberWithBool:YES]];
} else {
[marks addObject:[NSNumber numberWithBool:NO]];
}
d = [cal dateByAddingComponents:offsetComponents toDate:d options:0];
}
return [NSArray arrayWithArray:marks];
}
I hope, this helped you. Please let me know if you face any problem.
