Question

I am using the above mentioned Calendar API. In CalendarTestViewController.m class we are getting the date. Now I have declared a global variable nsstring type and I want to use that date into another new class by using global variable. I have tried this a number of times but unable to get the output. If anyone know how can I use the selected date by using Calendar API, then please give me some solution.

Thanks in advance.

CODE

- (void)calendarView:(KLCalendarView *)calendarView tappedTile:(KLTile *)aTile{ 
NSLog(@"Date Selected is %@",[aTile date]); 
str=(NSString *)[aTile date];
} 
NSLog(@"str:%@",str); 
glbdate1 = (NSString *)[aTile date]; 
NSLog(@"glbdate1:%@",glbdate1);
} 
//I have declared the glbdate1 variable globally in app delegate file and i have made the new class calenderview 
//I want to display the date in textfield by using global variable. Here is code in calenderview

-(void)viewWillAppear:(BOOL)animated {
 if ([glbdate1 length] != 0) 
   { 
    from.text = glbdate1;
   } 
}

You have to convert the NSDate to NSString as follows,

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-mm-dd HH:mm:ss"];
NSString *dateString=[dateFormatter stringFromDate:date];

Then the same NSString value can be converted to NSDate as,

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-mm-dd HH:mm:ss"];
NSDate *dateFromString=[dateFormatter dateFromString:dateString];
