Passing an NSDate
- by Garry
I'm new to the iPhone and objective-c and I am still trying to get my head around ownership of objects so bear with me.
I have a DOBViewController that has a datepicker on it. I have created a custom init method:
-(id)initWithInitialDate(NSDate *)initialDate;
Another view controller has a date instance declared (NSDate *dob) that holds a value. I would like to pass this to the DOBViewController so that it can scroll the datepicker to the passed value.
Here is the custom init method:
- (id)initWithInitialDate:(NSDate *)initialDate {
// Initialise ourselves
self = [super init];
// Set the date of the date picker
if (initialDate != nil) {
datePicker.date = initialDate;
}
else {
// Set it to today
datePicker.date = [NSDate date];
}
return self;
}
This is how I am sending the dob NSDate object:
DOBViewController *dobViewController = [[DOBViewController alloc] initWithInitialDate:dob];
Where dob is a variable of type NSDate that is declared in the header file.
This doesn't seem to work as initialDate is always NULL. What am I doing wrong?
