#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]; 
}

你應該用你UITextField的inputView屬性，以使機械臂表演到位鍵盤。 iOS6會照顧你的一切（然後用動畫而不是鍵盤顯示選取器等）。

注：你可能會想添加一些inputAccessoryView太（通常爲UIToolBar，在它的一些「OK」按鈕），以使用戶能夠關閉該選擇器（你的「OK」按鈕IBAction會簡單因爲UIDatePicker沒有任何按鈕來驗證你的輸入（而鍵盤有它的「返回鍵」）
