I have an array containing birth dates like the one below:
Array(
"11/07/2013",
"07/10/2013",
"20/02/2013"
)
Now I want to make a new array based on whether or not the date has passed. Writing this question in 2013, if a current date has passed then we will change that date's year to 2014. If it hasn't passed then we will have it stay the 2013 date.
For example:
NewArray(
"11/07/2013", no change cus this date hasnt passed yet
"07/10/2013", no change same as above
"20/02/2014" **as date has already passed thats why 2014**
I'm using the following code for this
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy"];
NSString *curYear = [dateFormatter stringFromDate:[NSDate date]];
NSString *nextYear = [NSString stringWithFormat: #"%d", ([curYear intValue] + 1)];
for(int i = 0; i < [_newlymadeArray count]; i++)
{
NSString *dateStr = [_newlymadeArray objectAtIndex:i];
NSComparisonResult comResult = [[dateFormatter dateFromString:dateStr] compare: [NSDate date]];
if(comResult == NSOrderedAscending)
{
[dateStr stringByReplacingOccurrencesOfString:curYear withString:nextYear];
[_newlymadeArray replaceObjectAtIndex:i withObject:dateStr];
NSLog(#"_newlymadeArray%#",_newlymadeArray);
}
NSLog(#"_newlymadeArray%#",_newlymadeArray);
This is however what I get when I NSLog _newlymadeArray:
after replacing (
"11/07/2013",
"07/10/2013",
"20/02/2013"
)
At index 2 it should be "20/02/2014" instead of the 2013 date. What might cause my problem and how can I solve it?
I've made some modifications to your code, and it is working as you want.
In my code I've compared date, which is in Ascending form of current date. If it satisfies the condition, then I've fetched YEAR from matched date, by the DateFormatter "yyyy". Then I simply increment this year by 1, and replace this year in old Date, which is "20/02/2013" to "20/02/2014"
array = [[NSMutableArray alloc] initWithObjects:#"11/07/2013",#"07/10/2013",#"20/02/2013", nil];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy"];
for(int i = 0; i < [array count]; i++)
{
NSString *dateStr = [array objectAtIndex:i];
NSComparisonResult comResult = [[dateFormatter dateFromString:dateStr] compare: [NSDate date]];
if(comResult == NSOrderedAscending)
{
NSDateFormatter *yrFormatter = [[NSDateFormatter alloc] init];
[yrFormatter setDateFormat:#"yyyy"];
NSString *curYear = [yrFormatter stringFromDate:[NSDate date]];
NSString *nextYear = [NSString stringWithFormat: #"%d", ([curYear intValue] + 1)];
NSLog(#"%#",curYear);
NSLog(#"%#",nextYear);
dateStr = [dateStr stringByReplacingOccurrencesOfString:curYear withString:nextYear];
NSLog(#"%#",dateStr);
[array replaceObjectAtIndex:i withObject:dateStr];
NSLog(#"_newlymadeArray%#",array);
}
NSLog(#"_newlymadeArray%#",array);
}
This seems to be working perfectly, so I hope it helps you.
Plese dear try to use this one.I think this one may help
NSCalendar* calendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDateComponents* components = [[NSDateComponents alloc] init];
components.year = 1;
NSDate* newDate = [calendar dateByAddingComponents: components toDate:#"YourDate" options: 0];
Otherwise you can use this one code.
if (comResult == NSOrderedSame)
{
NSCalendar* calendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDateComponents* components = [[NSDateComponents alloc] init];
components.year = 1;
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:#"dd/MM/yyyy"];
NSDate *date = [formatter dateFromString:#"11/07/2013"];
NSDate* newDate = [calendar dateByAddingComponents: components toDate:date options: 0];
// here replace your array object with this "newDate"
}
Compare your array date to today's date with NSDate compare function. Here are the details:
NSString *arrayDateString = #"20/02/2013" // fetch this string from your array
NSDate *todaysDate = [NSDate date];
NSDateFormatter* df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"dd/MM/yyyy"];
NSDate* d = [df dateFromString:arrayDateString];
// now compare this date (d) with todaysDate using NSDate function
if ([d compare:todaysdate]== NSOrderedAscending)
{//write your code here}
If it results NSOrderedAscending, then it means array date is earlier than today's date.
So for that date, update year incremented by one using NSDateComponents:
NSDateComponents *dayComponent = [[[NSDateComponents alloc] init] autorelease];
dayComponent.year = 1;
NSCalendar *theCalendar = [NSCalendar currentCalendar];
dateToBeIncremented = [theCalendar dateByAddingComponents:dayComponent toDate:dateToBeIncremented options:0];
Or you can use NSDate function itself:
NSDate *now = arrayDate;
int yearsToAdd = 1;
NSDate *newDate1 = [now dateByAddingTimeInterval:60*60*24*365*year];
But second option is not full-proof - because of leap year problem.
Hope this two options help you, for solving your issue.
NSArray * array = [[NSArray alloc] initWithObjects:#"11/07/2013",#"07/10/2013",#"20/02/2013", nil];

[dateFormatter setDateFormat:#"dd/MM/yyyy"];
NSDate *now = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
NSMutableArray *output = [NSMutableArray new];
for(int i = 0; i < [array count]; i++)
{
NSString *dateStr = [array objectAtIndex:i];
NSDate *date = [dateFormatter dateFromString:dateStr];
if ([date compare:now] == NSOrderedAscending)
{
[components setYear:1];
date = [calendar dateByAddingComponents:components toDate:date options:0];
}
dateStr = [dateFormatter stringFromDate:date];
[output addObject:dateStr];
}
NSLog(#"Result : %#",output);
I am trying to create a new calendar in iCal. Now I am able to create a new Calendar with some name. But my problem is when I try to create to Local calendar I cant see it in calendar list. Any one have any idea about this? I have tried using all types of sources but not able to find exact solution for this.
Thank you in advance.

Try this code you will get the desired result.
I have a date with the format:
Fri Jul 16 16:58:46 +0000 2010.
To convert it to Fri Jul 16 2010 I tried:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
for(int i=0; i<[self.data count]; i++) {
id celldata = [self.data objectAtIndex:i];
NSString *str = [NSString stringWithFormat:#"%#", [celldata objectForKey:#"created_at"]];
NSLog(#"date for %u is %#",i, str); //this works and writes the date
[df setDateFormat:#"eee MMM dd HH:mm:ss Z yyyy"];
NSDate *date = [df dateFromString:str];
[df setDateFormat:#"eee MMM dd yyyy"];
NSString *dateStr = [df stringFromDate:date];
NSLog(#"%#",dateStr);
}
But NSLog(#"%#",dateStr) only writes (null). How to get it working?
EDIT
For whatever reason I got it working by changing
[df setDateFormat:#"eee MMM dd HH:mm:ss Z yyyy"];
to
[df setDateFormat:#"MMM dd HH:mm:ss Z yyyy"];
and deleting the week day from my string. However, thank you all.
This might help you out a bit. I had a similar problem a while back, so I created the following methods.

Example
NSDate * date = [self getDateWithMonth:12 day:24 year:1994];
NSString * dateInString = [self getStringFromDate:date dateType:DATE_TYPE_MMDDYYYY];
int month = [[[dateInString componentsSeparatedByString:#"|"] objectAtIndex:0] intValue];
int day = [[[dateInString componentsSeparatedByString:#"|"] objectAtIndex:1] intValue];
int year = [[[dateInString componentsSeparatedByString:#"|"] objectAtIndex:2] intValue];
NSLog(#"String of Date: \"%#\"", dateInString);
NSLog(#"Month: %d", month);
NSLog(#"Day: %d", day);
NSLog(#"Year: %d", year);
The method [self getDateWithMonth:12 day:24 year:1994] returns an NSDate object which is usually hard to read, so you can use [self getStringFromDate:date dateType:DATE_TYPE_MMDDYYYY] to get a string of an NSDate object.
Use the definitions (macros) to specify the format of the date you would like to get in the string.
For example:
DATE_TYPE_hhmmss would return the Hour|Minute|Second,
DATE_TYPE_MMDDYYYY would return the Month|Day|Year,
DATE_TYPE_MMDDYYYYhhmmss would return the Month|Day|Year|Hour|Minute|Second,
DATE_TYPE_MMDDYYYYWWhhmmss would return the Month|Day|Year|Weekday (#)|Hour|Minute|Second
and so on...

If the original strings you are parsing to dates are really in the format of "20081122" then the first call to "setDateFormat" is incorrect in both snippets, as the format of the specified is incorrect.
Assuming that [celldata objectForKey:#"created_at"] is returning dates in the format of "20081122" per your second code snippet, you need to change the first call to setDateFormat to use the correct format for the string, "yyyyMMdd" This will drive a correct conversion when you call the method "dateFromString" Then, once you have a NSDate* object representation, you can use whatever format you need when you convert it back to a string via stringFromDate.
NSString *dateStr = #"20081122";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
//This is the important change here, this format MUST match the format of the string.
[dateFormat setDateFormat:#"yyyyMMdd"];
NSDate *date = [dateFormat dateFromString:dateStr];
[dateFormat setDateFormat:#"EEEE MMMM d, YYYY"];
dateStr = [dateFormat stringFromDate:date];
[dateFormat release];
Use Dateformatter for week EEE instead of eee
[df setDateFormat:#"EEE MMM dd HH:mm:ss Z yyyy"];
I hope this will be helpful to you...
Right now my dates look like this:`2011-01-01 5:45:23 +0000
I want them to look like this: 2011-01-01 00:00:00 +0000 (notice how everything is 00 beside the date, month, and year).
I have an array of NSdates which is fetched from this code:
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"Session" inManagedObjectContext:self.managedObjectContext];
[request setEntity:entity];
[request setResultType:NSDictionaryResultType];
[request setReturnsDistinctResults:YES]; //set to YES if you only want unique values of the property
[request setPropertiesToFetch :[NSArray arrayWithObject:#"timeStamp"]]; //name(s) of properties you want to fetch
NSError *error;
NSArray *objects = [managedObjectContext executeFetchRequest:request error:&error];
NSArray *data = [objects valueForKey:#"timeStamp"];
NSLog(#"The content of data is%#", data);
I want to remove daylight savings and have 0:00:00 for the time aspect of each date, thus I need this NSDateFormatter method:
NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"]; // e.g., set for mysql date strings
[formatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"GMT"]];
NSString* mysqlGMTString = [formatter stringFromDate:[NSDate date]];
So how can I combine the two to work together?
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init];
[formatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"];
[formatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"GMT"]];
for (NSDate *d in data) {
NSString* mysqlGMTString = [formatter stringFromDate:d];
// ...
}
[formatter release];
Since your requirement is to have strings in the data array, this code should suit your purpose.
NSMutableArray * resultsArray = [NSMutableArray array];
NSCalendar * gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];
[gregorian setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"GMT"]];
NSUInteger flags = ( NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit );
NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setDateFormat:#"yyyy-MM-dd HH:mm:ss Z"];
[formatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"GMT"]];
[datesArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
NSDate * date = [gregorian dateFromComponents:[gregorian components:flags fromDate:obj]];
[resultsArray addObject:[formatter stringFromDate:date]];
}];
resultsArray will contain the strings that you need. Now you can have data referring to the object
As for the search with a date part,
- (void)calendarMonthView:(TKCalendarMonthView *)monthView didSelectDate:(NSDate *)d {
// Assuming `data` is from the code above & the date is in `00:00:00 +0000` form.
NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setDateFormat:#"yyyy-MM-dd HH:mm:ss Z"];
[formatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"GMT"]];
NSString * dateString = [formatter stringFromDate:d];
if ( [data containsObject:dateString] ) {
// Push object to detail view??
}
}
Also use yyyy instead of YYYY. They are not the same.
When I push a view, I am getting the following errors in the console:
nested push animation can result in corrupted navigation bar
Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.
Any ideas how to fix this?
This is the method that pushes the new veiw:
