In case you are working on a Table View Cell and you are not using a UITextField (hence you won't be using the Accessory View), here's what I did:

I created a table view cell called GWDatePickerCell that looks like this (no .nib files involved).

GWDatePickerCell.h:

#import 

@interface GWDatePickerCell : UITableViewCell

@property (nonatomic, strong) UIDatePicker *datePicker;
@property (nonatomic, strong) UIToolbar *toolbar;
@property (nonatomic, strong) UIBarButtonItem *buttonDone;

@end

GWDatePickerCell.m:

    #import "GWDatePickerCell.h"

    @implementation GWDatePickerCell

    - (id) initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
        if(!(self=[super initWithStyle:style reuseIdentifier:reuseIdentifier])) return nil;

    _datePicker = [[UIDatePicker alloc] init];
    [_datePicker setMinuteInterval:5];
    [_datePicker setDatePickerMode:UIDatePickerModeDateAndTime];
    [self.contentView addSubview:_datePicker];

    _toolbar = [[UIToolbar alloc] init];
    _buttonDone = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:nil action:nil];
    _toolbar.items = @[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil], _buttonDone];
    [self.contentView addSubview:_toolbar];

    return self;
}

- (void)layoutSubviews{
    [super layoutSubviews];
    CGRect r = self.contentView.bounds;
    r.origin.y +=44;
    r.size.height = 216;
    CGRect tb = self.contentView.bounds;
    tb.size.height = 44;
    _datePicker.frame = r;
    _toolbar.frame = tb;
}

@end

Now all I had to do when creating the cells in the Table View:

• Specify the @selector for the Done button.
• Set the correct cell height in heightForRowAtIndexPath
