cancel button appears but done button does not appear in uitoolbar - ios

Question

I have written the code below to display the datepicker in popover along uitoolbar.
I can see the cancel button but not the Done button.
If I remove the code for flexspace then done button appears but I need the done button to be on the extreme right positon but it stands next to cancel button.
How can I fix this ? Thanks in Advance.

UIView *popoverView = [[UIView alloc] init]; //view
popoverView.backgroundColor = [UIColor blackColor];
datePicker=[[UIDatePicker alloc]init];//Date picker

datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker setMinuteInterval:5];
[datePicker setTag:10];
[datePicker addTarget:self action:#selector(Result) forControlEvents:UIControlEventValueChanged];
[popoverView addSubview:datePicker];
popoverContent.view = popoverView;
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
popoverController.delegate=self;
[popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];
[popoverController presentPopoverFromRect:self.uitext.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];//tempButton.frame where you need you can put that frame

Try this code :-
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width,40)];
[pickerToolbar sizeToFit];
pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
[barItems addObject:cancelBtn];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
[barItems addObject:doneBtn];
[pickerToolbar setItems:barItems animated:YES];
[popoverView addSubview:pickerToolbar];
Hope it helps you..
EDIT :-
Add this line below [pickerToolbar setItems:barItems animated:YES]; :-
pickerToolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
and comment [pickerToolbar sizeToFit]; line
So your code will be
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width,44.0)];
//[pickerToolbar sizeToFit];
pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
[barItems addObject:cancelBtn];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
[barItems addObject:doneBtn];
[pickerToolbar setItems:barItems animated:YES];
pickerToolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
[popoverView addSubview:pickerToolbar];
