Share custom data with today extension by NSUserDefaults - ios

Question

this is my first post, so please be kind and constructive with me.
Im trying to share an array of custom objects with my Today Extension via NSuserDefauls.
I know that I can't put custom objects in NSUserdefaults so i coded them by NSKeyedArchiver - NSKeyedUnarchiver to transform them in NSData.
This is my custom class
#import "Counter.h"
#implementation Counter
#dynamic city;
#dynamic address;
#dynamic event;
#dynamic date;
#dynamic time;
#dynamic counter;
#dynamic latitude;
#dynamic longitude;
- (void)encodeWithCoder:(NSCoder *)encoder
{
//Encode properties, other class variables, etc
[encoder encodeObject:self.city forKey:#"city"];
[encoder encodeObject:self.address forKey:#"address"];
[encoder encodeObject:self.event forKey:#"event"];
[encoder encodeObject:self.date forKey:#"date"];
[encoder encodeObject:self.time forKey:#"time"];
[encoder encodeObject:self.counter forKey:#"counter"];
[encoder encodeObject:self.latitude forKey:#"latitude"];
[encoder encodeObject:self.longitude forKey:#"longitude"];
}
- (id)initWithCoder:(NSCoder *)decoder
{
self = [super init];
if( self != nil )
{
self.city = [decoder decodeObjectForKey:#"city"];
self.address = [decoder decodeObjectForKey:#"address"];
self.event = [decoder decodeObjectForKey:#"event"];
self.date = [decoder decodeObjectForKey:#"date"];
self.time = [decoder decodeObjectForKey:#"time"];
self.counter = [decoder decodeObjectForKey:#"counter"];
self.latitude = [decoder decodeObjectForKey:#"latitude"];
self.longitude = [decoder decodeObjectForKey:#"longitude"] ;
}
return self;
}
#end
This is the coding function inside the app.
- (void)saveInUserDefault {
//Counter is my Custom class
//I'm Using MagicalRecord
NSArray *array = [Counter MR_findAllSortedBy:#"date" ascending:NO];
NSMutableArray *defaultMutableArray = [NSMutableArray arrayWithCapacity:array.count];
NSUserDefaults *defaultArray = [[NSUserDefaults alloc] initWithSuiteName:#"group.LorenzoLoRe.Everycount"];
for (Counter *cnt in array) {
NSData *dataToDefault = [NSKeyedArchiver archivedDataWithRootObject:cnt];
[defaultMutableArray addObject:dataToDefault];
}
[defaultArray setObject:defaultMutableArray forKey:#"counts"];
[defaultArray synchronize];
}
At this point looking at the log, data seems to be write in NSUserDefaults
And here i try to retrive the data in the Extension
-
(void)takeLastCounts {
NSUserDefaults *defaultArray = [[NSUserDefaults alloc] initWithSuiteName:#"group.company.product"];
[defaultArray synchronize];
NSArray *dummyArray = [defaultArray arrayForKey:#"counts"];;
NSMutableArray *arrayFromDefault= NULL;
Counter *cter = nil;
for (NSData *data in dummyArray) {
cter = [NSKeyedUnarchiver unarchiveObjectWithData:data];
[arrayFromDefault addObject:cter];
}
self.cnt_1 = arrayFromDefault[0];
self.cnt_2 = arrayFromDefault[1];
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateStyle:NSDateFormatterShortStyle];
self.eventLabel.text = self.cnt_1.event;
self.dateLabel.text = [formatter stringFromDate:self.cnt_1.date];
self.counterLabel.text = self.cnt_1.counter.stringValue;
self.timeLabel.text = self.cnt_1.time;
}
When i try to execute the Extension, theres no errors but just empty Arrays.
In particular NSArray *dummyArray = [defaultArray arrayForKey:#"counts"]; seems to be empty, so somewhere the data don't flows.
What I'm doing wrong??
Any kind of tips will be ver appreciate.
