NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *currentDate = [NSDate date];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setYear:30];
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];

Answer 4

  //Get Current Date
    NSDate *currentTime = [NSDate date];
    [DatePicker setMinimumDate:currentTime];

尝试设置最大日期，它会将最大值完全设置为年份

    NSString *dateString = @"01-02-2010";
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    // this is imporant - we set our input date format to match our input string
    // if format doesn't match you'll get nil from your string, so be careful
    [dateFormatter setDateFormat:@"dd-MM-yyyy"];
    NSDate *dateFromString = [[NSDate alloc] init];

    dateFromString = [dateFormatter dateFromString:dateFromString];
    [datePicker setMaximumDate: dateFromString];
