UIDatePicker e NSDate

Question

Eu tenho um NSDate que eu recebo de uma UIDatePicker.

IBOutlet UIDatePicker *dueDate;
NSDate *selectedDate = [dueDate date];

Como faço para recuperar o mês de dueDate na forma de um int? (Um para Jan, 2 para fevereiro, etc.)

Answer 1

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:NSMonthCalendarUnit fromDate:[dueDate date]];
NSInteger month = [components month];

Answer 2

uso -[NSCalendar components:fromDate:] por exemplo, o exemplo aqui:

Answer 3

NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] initWithDateFormat:@"%m" allowNaturalLanguage:NO] autorelease];
int month = [[dateFormat stringFromDate:dueDate] intValue];
