Hi first of all minimum date must be 100 year back date and max date must be 18 year back date and then set pickerView's date to a date between range of dates so your final code will be looks like
嗨，首先最小日期必须是 100 年前的日期，最大日期必须是 18 年前的日期，然后将 pickerView 的日期设置为日期范围之间的日期，因此您的最终代码将如下所示
NSCalendar * gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDate * currentDate = [NSDate date];
NSDateComponents * comps = [[NSDateComponents alloc] init];
[comps setYear: -18];
NSDate * maxDate = [gregorian dateByAddingComponents: comps toDate: currentDate options: 0];
[comps setYear: -100];
NSDate * minDate = [gregorian dateByAddingComponents: comps toDate: currentDate options: 0];
[comps release];
self.datePickerView.minimumDate = minDate;
self.datePickerView.maximumDate = maxDate;
self.datePickerView.date = minDate;
Hopefully this will be helpful for you.
希望这对你有帮助。

Here is viewDidLoad method of view controller class
这是视图控制器类的 viewDidLoad 方法
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSCalendar * gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDate * currentDate = [NSDate date];
NSDateComponents * comps = [[NSDateComponents alloc] init];
[comps setYear: -18];
NSDate * maxDate = [gregorian dateByAddingComponents: comps toDate: currentDate options: 0];
[comps setYear: -100];
NSDate * minDate = [gregorian dateByAddingComponents: comps toDate: currentDate options: 0];
[comps release];
UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 0, 320, 300)];
[pickerView setMinimumDate:minDate];
[pickerView setMaximumDate:maxDate];
[pickerView setDate:minDate];
[[self view] addSubview:pickerView];
