Objective-C Language NSDate Convert NSDate that is composed from hour and minute (only) to a full NSDate
Example
There are many cases when one has created an NSDate from only an hour and minute format, i.e: 08:12
The downside for this situation is that your NSDate is almost completely "naked" and what you need to do is to create: day, month, year, second and time zone in order to this object to "play along" with other NSDate types.
For the sake of the example let's say that hourAndMinute is the NSDate type that is composed from hour and minute format:
NSDateComponents *hourAndMintuteComponents = [calendar components:NSCalendarUnitHour | NSCalendarUnitMinute
fromDate:hourAndMinute];
NSDateComponents *componentsOfDate = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear
fromDate:[NSDate date]];
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setDay: componentsOfDate.day];
[components setMonth: componentsOfDate.month];
[components setYear: componentsOfDate.year];
[components setHour: [hourAndMintuteComponents hour]];
[components setMinute: [hourAndMintuteComponents minute]];
[components setSecond: 0];
[calendar setTimeZone: [NSTimeZone defaultTimeZone]];
NSDate *yourFullNSDateObject = [calendar dateFromComponents:components];
Now your object is the total opposite of being "naked".
