Objective-c : initialize instance var

Question

I am new to objective-c. My object reportingTime is nil in init method. What I am doing wrong ? How can I initialize reportingTime and set firstweekday ?

I have the following interface and implementation

My interface file Calculation.h

@interface Calculate : NSObject {

NSCalendar *reportingTime;
....
....
}
@property NSCalendar *reportingTime;

@end

And my implementation file Calculate.m

#import "Calculate.h"

@implementation Calculate

@synthesize reportingTime;

- (id)init
{
    if(self = [super init]) {
        reportingTime = [[NSCalendar alloc] init];
        [reportingTime setFirstWeekday:1];

        // reportingTime is nil ??????
    }
    return self;
}

Use

- (id)initWithCalendarIdentifier:(NSString *)string

instead of standart init method. See more: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSCalendar_Class/Reference/NSCalendar.html

And why is #import "Calculate.m" in Calculate.m?

Instead of

reportingTime = [[NSCalendar alloc] init];

use:

reportingTime = [[NSCalendar currentCalendar] retain];

The retain because this is a direct assignment to the @property ivar and [NSCalendar currentCalendar] is a convenience method that returns an autoreleased var. If you are using ARC the retain is not necessary.
