[dhekrazaied]

when use the code with ios project with objective c and I get this error fatal error: unexpectedly found nil while unwrapping an Optional value this is my code -(IBAction)goToPickerDateTime:(id)sender{

self.selectorCal = [[WWCalendarTimeSelector alloc]init];
self.selectorCal.delegate = self;
self.selectorCal.optionCurrentDate = self.singleDate;
self.selectorCal.optionCurrentDates = self.multipleDates;
[self.selectorCal.optionStyles showDateMonth:true];
[self.selectorCal.optionStyles  showMonth:false];
[self.selectorCal.optionStyles showYear:false ];
[self.selectorCal.optionStyles showTime:false];
[self.selectorCal.optionCurrentDateRange setStartDate :   self.singleDate ];
[self.selectorCal.optionCurrentDateRange setEndDate:   self.singleDate];
[self presentViewController:self.selectorCal animated:YES completion:nil];

}

Hi, please try init by calling the designated instantiate() method instead of alloc()init()

Something like [WWCalendarTimeSelector instantiate];

same error fatal error: unexpectedly found nil while unwrapping an Optional value

Hi @dhekrazaied

Perhaps you could try this because I'm not having any issues with it (:

#import "ViewController.h"
#import <WWCalendarTimeSelector/WWCalendarTimeSelector-Swift.h>

@interface ViewController () <WWCalendarTimeSelectorProtocol>

@property (strong, nonatomic) NSDate *singleDate;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.singleDate = [NSDate new];
}

- (IBAction)openCalendar:(id)sender {
    WWCalendarTimeSelector *cal = [WWCalendarTimeSelector instantiate];
    cal.delegate = self;
    cal.optionCurrentDate = self.singleDate;
    [cal.optionStyles showDateMonth:true];
    [cal.optionStyles  showMonth:false];
    [cal.optionStyles showYear:false ];
    [cal.optionStyles showTime:false];
    [cal.optionCurrentDateRange setStartDate :   self.singleDate ];
    [cal.optionCurrentDateRange setEndDate:   self.singleDate];
    [self presentViewController:cal animated:YES completion:nil];
}

- (void)WWCalendarTimeSelectorDone:(WWCalendarTimeSelector *)selector date:(NSDate *)date {
    self.singleDate = date;
}

@end

I think I have a problem in the .storyboard file not in the code

[weilsonwonder]

Hi, please explain in detail what happens to storyboard file. I'm having no issues on my side by creating a new objective c project, and installing the library through cocoapods (:

[dhekrazaied]

I didn't use cocopods I just add folder and files, and I modified the target of wwcalendertimeselector.storyboard in the inspector from wwcalendertimeselector to the current project

[weilsonwonder]

Hi, apologies for the inconvenience. The problem (happened in another issue) was the Module in custom class. It's supposed to be empty (so that it's default), and not pointing to WWCalendarTimeSelector.

[weilsonwonder]

The UIViewController itself might be pointing to the same WWCalendarTimeSelector. Do delete the defined module, and it should work.

[dhekrazaied]

thx a lot it's work perfectly now. Best regards.

Is it chances to crash app.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"WWCalendarTimeSelector" bundle:nil];

WWCalendarTimeSelector *selector = (WWCalendarTimeSelector *)[storyboard instantiateInitialViewController];

selector.delegate = self;

[selector.optionStyles showDateMonth:YES];
[selector.optionStyles showMonth:NO];
[selector.optionStyles showYear:NO];
[selector.optionStyles showTime:NO];
selector.optionCurrentDate = leftDate;
selector.optionIdentifier = @"1";
[self presentViewController:selector animated:YES completion:nil];

thanks in advance.
