I am using FSCalender through cocoa pods. I simply want to get the selected date/month/year. I am only getting current date. I am getting details like this :-
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = #"dd.MM.yyyy";
NSString *string = [formatter stringFromDate:[NSDate date]];
NSLog(#"CurrentDate=%#",string);
In string, I am getting output :-
CurrentDate=08.02.2017
How to achieve this. Thanks in advance.
There is a delegate method in FSCalendar for this
// FSCalendarDelegate
- (void)calendar:(FSCalendar *)calendar didSelectDate:(NSDate *)date
{
// Do something
// get year , month and day of selected date.
NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:date];
NSInteger day = [components day];
NSInteger month = [components month];
NSInteger year = [components year];
}
Here you will get a object of NSDate, and then you can convert it into your desired format.
Please read the full documentation of this library FSCalendar
To get day/Month/year from Date you can refer following Stack overflow answer :

How can I get month calendar start and end date?
From the screenshot, I need to get 1 aug 2017 and 31 aug 2017 in fscalender?
when i scroll then this method call but everytime get current date
- (void)calendarCurrentPageDidChange:(FSCalendar *)calendar;
{
}
thanks!
You can use these two NSDate category methods for your need:
- (NSDate *)startDateOfMonth {
NSCalendar *current = [NSCalendar currentCalendar];
NSDate *startOfDay = [current startOfDayForDate:self];
NSDateComponents *components = [current components:(NSCalendarUnitMonth | NSCalendarUnitYear) fromDate:startOfDay];
NSDate *startOfMonth = [current dateFromComponents:components];
return startOfMonth;
}
- (NSDate *)endDateOfMonth {
NSCalendar *current = [NSCalendar currentCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
components.month = 1;
components.day = -1;
NSDate *endOfMonth = [current dateByAddingComponents:components toDate:[self startDateOfMonth] options:NSCalendarSearchBackwards];
return endOfMonth;
}
You need to convert the date from your FSCalendar to NSDate:
- (void)calendarCurrentPageDidChange:(FSCalendar *)calendar {
NSDate *date = ... //Conversion goes here
NSDate *startDateOfMonth = [date startDateOfMonth];
NSDate *endDateOfMonth = [date endDateOfMonth];
// convert back if you need to
}
The FSCalendar property currentPage returns the start date of currently showing page - this is the first day of the month or week depending on whether you are showing a month or week.
Then use NSCalendar methods to find the last day of the month or week that starts with currentPage. There are a number of ways to do this; e.g. add an NSDateComponents value or use one of the "next" methods such as nextDateAfterDate:matchingUnit:value:options:.
HTH
Get First date
- (void)calendarCurrentPageDidChange:(FSCalendar *)calendar;
{
NSLog(#"did change to page %#",[self.dateFormatter stringFromDate:calendar.currentPage]);
}
-(void)calendarCurrentPageDidChange:(FSCalendar *)calendar{
[self.calendar selectDate:[self.calendar.currentPage fs_firstDayOfMonth]];
[self.calendar selectDate:[self.calendar.currentPage fs_lastDayOfMonth]];
}
You get First and Last date of Current Month by yourself. No need to get it from FSCalendar. For this see below code.
NDDate *currentDate = //Pass date which you get
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
NSDateComponents *comp = [gregorian components:(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay ) fromDate:currentDate];
[comp setMonth:[comp month]];
[comp setDay:1];
NSDate *firstDayDate = [gregorian dateFromComponents:comp];
[comp setMonth:[comp month]+1];
[comp setDay:0];
NSDate *lastDayDate = [gregorian dateFromComponents:comp];
NSLog(#"First : %#, Last : %#",firstDayDate,lastDayDate);
This way you are getting First and Last Date.
Hello I have a date string like this.11/14/2016. What I want to do is check it whether is it
Today or This week or This month. I can compare today and the month. But how can I check whether this date belongs to "This Week"
Please help me.
Thanks
Given two dates,
NSDate *now = [NSDate date];
NSDate *then = // some other date
Find out if they're in the same week with:
BOOL sameWeek = [[NSCalendar currentCalendar] isDate:then equalToDate:now
toUnitGranularity:NSCalendarUnitWeekOfYear];
That line asks if they're "equal" with a granularity of a week, meaning that they're "equal" if they're in the same week.
Try below code,
- (void)thisWeek:(NSDate *)date
{
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *todaysComponents = [gregorian components:NSCalendarUnitWeekOfYear fromDate:[NSDate date]];
NSUInteger todaysWeek = [todaysComponents weekOfYear];
NSDateComponents *otherComponents = [gregorian components:NSCalendarUnitWeekOfYear fromDate:date];
NSUInteger datesWeek = [otherComponents weekOfYear];
//NSLog(#"Date %#",date);
if(todaysWeek==datesWeek){
NSLog(#"Date is in this week");
}else if(todaysWeek+1==datesWeek){
NSLog(#"Date is in next week");
}
}
I am trying to get the days of a week in reference to their date.
Ex.: 14th October is a Wednesday.
I am creating a collection view cell and displaying the date as follows.
In the 14th cell it would display Wednesday, but how to get the next day as Thursday, then Friday...and so on.
I have got todays date and which day it is as follows,
day = [components day];
week = [components month];
year = [components year];
weekday = [components weekday];
NSString *string = [NSString stringWithFormat:#"%ld.%ld.%ld", (long)day, (long)week, (long)year];
NSLog(#"%#",string);
NSDate *todayDate = [NSDate date]; // get today date
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEEE"];
NSString *convertedDateString = [dateFormatter stringFromDate:todayDate];// here convert date in
NSLog(#"Today formatted date is %#",convertedDateString);
And i have found this method online, which returns the days in string when you pass the integer, but i am having trouble in this too, not understanding which integer to pass every time so I get different strings.
static inline NSString *stringFromWeekday(int weekday){
static NSString *strings[] = {
#"Sunday",
#"Monday",
#"Tuesday",
#"Wednesday",
#"Thursday",
#"Friday",
#"Saturday",
};
return strings[weekday];
}
You already got everything in place. You should be getting the correct day name in the convertedDateString string. You just have to add 24 hours to your todayDate object and use the dateformatter again to get the next day.
NSDate *todayDate = [NSDate date]; // get today date
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEEE"];
NSString *convertedDateString = [dateFormatter stringFromDate:todayDate];// here convert date in
You can get the next day like this.
NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:(NSDayCalendarUnit | NSMonthCalenderUnit | NSYearCalenderUnit | NSWeekdayCalendarUnit) fromDate:today];
[dateComponents setDay:dateComponents.day+1];
NSDate *nextDay = [dateComponents date];
// Get the day by following same approach in the top
You will get days in a week from today using below code.
NSDate *today = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *weekdayComponents =
[gregorian components:(NSDayCalendarUnit | NSWeekdayCalendarUnit) fromDate:today];
NSInteger day = [weekdayComponents day];
NSInteger weekday = [weekdayComponents weekday];
I'm using NSDateFormatter to format NSDate variables like this:
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = #"dd/MM";
I want to provide an unique format only for the first day of year(setDateFormat:#"dd/MM/yyyy").
Is it possible?
Thanks in advance.
You can use something like this to format your date,
NSDate *dateInAction = [NSDate date]; //Your date here
NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth fromDate:dateInAction];
NSInteger day = [components day];
NSInteger month = [components month];
if (day==1 && month==1) {
// Set formatter for first day of year
}else{
// all other days
}
I need to get the weekday of the first day of the month. For example, for the current month September 2013 the first day falls on Sunday.
At first, get the first day of current month (for example):
NSDate *today = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [gregorian components:(NSEraCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit) fromDate:today];
components.day = 1;
NSDate *firstDayOfMonth = [gregorian dateFromComponents:components];
Then use NSDateFormatter to print it as a weekday:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEEE"];
NSLog(#"%#", [dateFormatter stringFromDate:firstDayOfMonth]);
P.S. also take a look at Date Format Patterns
Here is the solution to getting the weekday name of the first day in the current month
NSDateComponents *weekdayComps = [[NSDateComponents alloc] init];
weekdayComps = [calendar.currentCalendar components:calendar.unitFlags fromDate:calendar.today];
weekdayComps.day = 1;
NSDateFormatter *weekDayFormatter = [[NSDateFormatter alloc]init];
[weekDayFormatter setDateFormat:#"EEEE"];
NSString *firstweekday = [weekDayFormatter stringFromDate:[calendar.currentCalendar dateFromComponents:weekdayComps]];
NSLog(#"FIRST WEEKDAY: %#", firstweekday);
For the weekday index, use this
NSDate *weekDate = [calendar.currentCalendar dateFromComponents:weekdayComps];
NSDateComponents *components = [calendar.currentCalendar components: NSWeekdayCalendarUnit fromDate: weekDate];
NSUInteger weekdayIndex = [components weekday];
NSLog(#"WEEKDAY INDEX %i", weekdayIndex);
You can also increment or decrement the month if needed.
Depending on the output you need you may use NSDateFormatter (as it was already said) or you may use NSDateComponents class. NSDateFormatter will give you a string representation, NSDateComponents will give you integer values. Method weekday may do what you want.
NSDateComponents *components = ...;
NSInteger val = [components weekday];
For Swift 4.2
First:
extension Calendar {
func startOfMonth(_ date: Date) -> Date {
return self.date(from: self.dateComponents([.year, .month], from: date))!
}
}
Second:
self.firstWeekDay = calendar.component(.weekday, from: calendar.startOfMonth(Date()))
