推荐答案

我看到你的链接并得到了解决方案，所以请尝试以下代码。

I see your link and got the solution so try the below code.

#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];  
}  

这段代码绝对可以帮到你，因为我运行代码并且工作正常。
