// label.font = HELVETICA_NEUE(24);
// label.textColor = GREEN_COLOR;
[dateofBirthDatePicker addTarget:self
action:@selector(LabelChange:)

You can use setMaximumDate: and setMinimumDate: on UIDatePicker object:
您可以在 UIDatePicker 对象上使用 setMaximumDate: 和 setMinimumDate: ：
[dateofBirthDatePicker setMaximumDate:[NSDate date]]; // The max date will be today
// Optional you can set up min date as well
[dateofBirthDatePicker setMinimumDate:yourMinDate];

NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *currentDate = [NSDate date];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setYear:1];
NSDate *maxDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];
[comps setYear:-30];
NSDate *minDate = [calendar dateByAddingComponents:comps toDate:currentDate options:0];
[datePicker setMaximumDate:maxDate];
[datePicker setMinimumDate:minDate];
