我看到了您的链接并获得了解决方案，因此请尝试以下代码。

#import "TextfieldwithDatepickerViewController.h"

UIActionSheet *pickerViewPopup;

@implementation TextfieldwithDatepickerViewController
- (void)textFieldDidBeginEditing:(UITextField *)aTextField{
    [aTextField resignFirstResponder];

    pickerViewPopup = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];

    UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];
    pickerView.datePickerMode = UIDatePickerModeDate;
    pickerView.hidden = NO;
    pickerView.date = [NSDate date];

    UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    pickerToolbar.barStyle = UIBarStyleBlackOpaque;
    [pickerToolbar sizeToFit];

    NSMutableArray *barItems = [[NSMutableArray alloc] init];

    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
    [barItems addObject:flexSpace];

    UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)];
    [barItems addObject:doneBtn];

    UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelButtonPressed:)];
    [barItems addObject:cancelBtn];

    [pickerToolbar setItems:barItems animated:YES];

    [pickerViewPopup addSubview:pickerToolbar];
    [pickerViewPopup addSubview:pickerView];
    [pickerViewPopup showInView:self.view];
    [pickerViewPopup setBounds:CGRectMake(0,0,320, 464)];
}

-(void)doneButtonPressed:(id)sender{
    //Do something here here with the value selected using [pickerView date] to get that value

    [pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];
}

-(void)cancelButtonPressed:(id)sender{
    [pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];
}

这段代码绝对可以为您提供帮助，因为我可以运行该代码并且可以正常运行。
