I'm trying to show a simple date picker with max date is today and min is 100 years ago but it doesn't work at all and the date picker have no limits.
CGRect frame = CGRectMake(0, CGRectGetHeight([UIScreen mainScreen].bounds)-250, CGRectGetWidth([UIScreen mainScreen].bounds), 250);
UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:frame];
datePicker.backgroundColor = [UIColor whiteColor];
datePicker.datePickerMode = UIDatePickerModeDate;
datePicker.minimumDate = [AppConfiguration currentDateMinusXYears:100];
datePicker.maximumDate = [NSDate date];
[datePicker addTarget:self action:#selector(datePicker:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:datePicker];
+ (NSDate *)currentDateMinusXYears:(NSInteger)xYears
{
NSDate *today = [NSDate new];
NSDateComponents *addComponents = [[NSDateComponents alloc] init];
addComponents.year = - xYears;
return [[NSCalendar currentCalendar] dateByAddingComponents:addComponents toDate:today options:0];
}
Any ideas why?
Edit 1:
I ended up using 3rd party code.
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setYear:30];
NSDate *maxDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];
[comps setYear:0];
NSDate *minDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];
[actionSheetPicker setMaximumDate:maxDate];
[actionSheetPicker setMinimumDate:minDate];

After Clicked...Date is not shown in textfield.
Textfield is in custom cell of tableview.
UIDatePicker *datePicker = [[UIDatePicker alloc]init];
[datePicker setDate:[NSDate date]];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:#selector(dateTextField:) forControlEvents:UIControlEventValueChanged];
[txtField_date setInputView:datePicker];
-(void) dateTextField:(id)sender
{
UIDatePicker *picker = (UIDatePicker*)txtField_date.inputView;
[picker setMaximumDate:[NSDate date]];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
NSDate *eventDate = picker.date;
[dateFormat setDateFormat:#"dd/MM/yyyy"];
NSString *dateString = [dateFormat stringFromDate:eventDate];
txtField_date.text = [NSString stringWithFormat:#"%#",dateString];
}
Try this code.
You can use the date property on UIDatePicker and convert it to NSString and set it to your UITextField.
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy"]; // set your own format
NSString *formattedDateString = [formatter stringFromDate:yourPicker.date];
textField.text = formattedDateString;
Hello I had been working with Photos.framework but now I am stuck with predicate comparison of PHFetchOptions class in documents I see that we can use startDate to use in predicate. So my code is this
#interface ViewController ()
{
NSMutableArray * moments;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
moments = [NSMutableArray array];
if([PHPhotoLibrary authorizationStatus] == PHAuthorizationStatusNotDetermined)
{
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
[self loadCollections];
}];
}else
{
[self loadCollections];
}
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self loadCollections];
}
- (NSDate*)dateAddingDays:(NSInteger)days ToDate:(NSDate*)argDate
{
NSCalendar * gregorian = [NSCalendar currentCalendar];
NSDateFormatter * formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:#"dd.MM.yyyy"];
NSString * dateString = [formatter stringFromDate:argDate];
NSDate * toWorkDate = [formatter dateFromString:dateString];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setDay:days];
NSDate *date = [gregorian dateByAddingComponents:comps toDate:toWorkDate options:0];
NSLog(#"%#",[formatter stringFromDate:date]);
return date;
}
- (void)loadCollections
{
PHFetchOptions * options = [[PHFetchOptions alloc]init];
options.predicate = [NSComparisonPredicate predicateWithFormat:#"startDate > CAST(%d,\"NSDate\")",[self dateAddingDays2:-1 ToDate:[NSDate date]].timeIntervalSince1970];
PHFetchResult * result = [PHAssetCollection fetchMomentsWithOptions:options];
if(result != nil)
{
NSLog(#"%i",result.count);
for (int i = 0; i < result.count; i++) {
NSLog(#"%#",[result objectAtIndex:i]);
[moments addObject:[result objectAtIndex:i]];
}
}
}
So my problem is this, I need fetch fotos from one day ago, I can make this work!! any help will be appreciated.
This is the answer, basically I replaced
- (NSDate*)dateAddingDays:(NSInteger)days ToDate:(NSDate*)argDate
{
NSCalendar * gregorian = [NSCalendar currentCalendar];
NSDateFormatter * formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:#"dd.MM.yyyy"];
NSString * dateString = [formatter stringFromDate:argDate];
NSDate * toWorkDate = [formatter dateFromString:dateString];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setDay:days];
NSDate *date = [gregorian dateByAddingComponents:comps toDate:toWorkDate options:0];
NSLog(#"%#",[formatter stringFromDate:date]);
return date;
}
by
- (NSDate*)yesterday
{
NSCalendar * gregorian = [NSCalendar currentCalendar];
return [gregorian startOfDayForDate:[gregorian dateByAddingUnit:NSCalendarUnitDay value:-1 toDate:[NSDate date] options:NSCalendarWrapComponents]];
}
and also replace this
options.predicate = [NSComparisonPredicate predicateWithFormat:#"startDate > CAST(%d,\"NSDate\")",[self dateAddingDays2:-1 ToDate:[NSDate date]].timeIntervalSince1970];
by this
options.predicate = [NSComparisonPredicate predicateWithFormat:#"(startDate > %#)",[self yesterday]];
and now is working!!! thanks to #Larme

Try This to select date from date picker...
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
datePicker =[[UIDatePicker alloc]initWithFrame:CGRectMake(50,150,10, 50)];
datePicker.datePickerMode=UIDatePickerModeDate;
datePicker.hidden=NO;
datePicker.date=[NSDate date];
[datePicker addTarget:self action:#selector(textFieldTitle:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:datePicker];
UIBarButtonItem * rightBtn=[[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(save:)];
self.navigationItem.rightBarButtonItem=rightBtn;
return true;
}
-(void)textFieldTitle:(id)sender
{
NSDateFormatter *dateFormat=[[NSDateFormatter alloc]init];
dateFormat.dateStyle=NSDateFormatterMediumStyle;
[dateFormat setDateFormat:#"MM/dd/yyyy"];
NSString *str=[NSString stringWithFormat:#"%#",[dateFormat stringFromDate:datePicker.date]];
self.txtField.text=str;
}
-(void)save:(id)sender
{
self.navigationItem.rightBarButtonItem=nil;
[datePicker removeFromSuperview];
}
To calculate the date....
NSDate *today = [NSDate date];
NSString *birthdate=self.txtField.text;
NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init];
[dateFormatter1 setDateFormat:#"dd-MM-yyyy"];
NSDate *myDate = [[NSDate alloc]init];
myDate=[dateFormatter1 dateFromString:birthdate];
NSDateComponents *ageComponents = [[NSCalendar currentCalendar]
components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay
fromDate:myDate
toDate:today
options:0];
NSLog(#"%#",ageComponents);
When I go to a viewcontroller in my app, I have two date pickers. Both of which have labels, and if either one is moved they update accordingly.
The start date is set to automatically be today's date. While it saves to Core Data just fine it doesn't display in the label unless I change it to a different day.
Basically when I load that screen the label should have today's date, and change if I change it in the date picker.
I figure it's something simple overlooking, but I can't figure out what it is, any help would be appreciated.

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
}
SO far what I got from ur question and code, simple mistake is as below :-
- (void)viewDidLoad
{
[super viewDidLoad];
....
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM-dd-yyyy "];
NSString *strDate = [dateFormatter stringFromDate:self.startDate.date];
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
if(!appDelegate.dateProductionDroneStartDate) //As initially this will be true and current date will be set.
[self.startDate setDate:[NSDate date]];
//So as you set the current date in self.startDate but not in label.
//Added below line for setting your label
else
{
[self.startDate setDate:appDelegate.dateProductionDroneStartDate];
}
self.productionDroneStartDate.text = strDate;
......
}
This should get you working further.
Why can't you just set the label with todays date at start without even touching the Picker. Then when the picker is moved as you suggest the label will be updated as expected.
I have an array of dates
NSArray *datesArray=[NSArray arrayWithObjects: #"2014-09-14 00:00:00",#"2014-08-21 07:12:36",#"2014-08-14 00:00:00",#"2014-07-14 00:00:00",#"2014-06-14 00:00:00",#"2015-01-01 10:00:00",#"2014-06-14 00:00:00",#"2014-05-14 11:24:15", nil];
now i want to fire one day before the date available in array
How to implement it?
I was trying this
NSDateFormatter *Formatter1 = [[NSDateFormatter alloc] init];
[Formatter1 setLocale:[[NSLocale alloc] initWithLocaleIdentifier:NSLocaleIdentifier]];
[Formatter1 setTimeZone:[NSTimeZone timeZoneWithName:#"UTC"]];
[Formatter1 setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
NSDate *date1 =[NSDate date];
NSString *string =[Formatter1 stringFromDate:date1];
NSLog(#"sring %#",string);
NSDate *todaydate =[Formatter1 dateFromString:string];
NSLog(#"2day date is %#",todaydate);
for (int i=0;i<datesArray.count;i++)
{
NSDate *_date =[Formatter1 dateFromString:[datesArray objectAtIndex:i ]];
NSLog(#"date is %#",_date);
if(_date == todaydate){
localNotif.fireDate = _date;
localNotif.alertBody = #"festival";
localNotif.alertAction=#"Show me";
localNotif.applicationIconBadgeNumber = 1;
localNotif.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
You can subtract a day by using the NSCalendar functions, specifically dateByAddingComponents
NSArray *datesArray = #[#"2014-09-14 00:00:00",#"2014-08-21 07:12:36",#"2014-08-14 00:00:00",#"2014-07-14 00:00:00",#"2014-06-14 00:00:00",#"2015-01-01 10:00:00",#"2014-06-14 00:00:00",#"2014-05-14 11:24:15"];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
[dateComponents setDay:-1];
NSDateFormatter *Formatter1 = [[NSDateFormatter alloc] init];
[Formatter1 setLocale:[[NSLocale alloc] initWithLocaleIdentifier:NSLocaleIdentifier]];
[Formatter1 setTimeZone:[NSTimeZone timeZoneWithName:#"UTC"]];
[Formatter1 setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
[datesArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = [calendar dateByAddingComponents:dateComponents toDate:[Formatter1 dateFromString:obj] options:0];
localNotif.alertBody = #"festival";
localNotif.alertAction = #"Show me";
localNotif.applicationIconBadgeNumber = 1;
localNotif.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}];
