答
首先，最短的约会日期必须为100年日期和最长日期必须是18年后的日期，然后将pickerView的日期设置为日期范围之间的日期，以便您的最终代码看起来像
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
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;
