You can do the following, in your implementation file create a local procedure
and then call it from your init
method. I did not bother copying your arguments but you define them in the
regular way.
-(void)myCalculation
{
// do the calculation
}
- (id) init
{
if ( self = [super init] ) {
// do your init
var3 = [self myCalculation];
}
return self;
}
