PickerView is not dismissing when Done button is pressed - ios

Question

I have created a text field that upon entry will open a picker view with a toolbar that contains a done button. However, when the done button is pressed the picker view doesn't dismiss. Everything else works just as I want except this. I've tried several options to no avail. Please review and let me know what I'm missing.
My code is below:
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
{IBOutlet UITextField *productDescription; IBOutlet UIPickerView *productPicker; NSArray *productListArray}
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
-(void)addPickerView{
productListArray = [[NSArray alloc]initWithObjects:
#"myArray", nil];
productDescription.delegate = self;
[self.view addSubview:productDescription];
[productDescription setPlaceholder:#"Product Description"];
productPicker = [[UIPickerView alloc]init];
productPicker.dataSource = self;
productPicker.delegate = self;
productPicker.showsSelectionIndicator = YES;
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc]
initWithTitle:#"Done" style:UIBarButtonItemStyleDone
target:self action:#selector(resignFirstResponder)];
UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:
CGRectMake(50, 320, 50, 50)];
[toolBar setBarStyle:UIBarStyleBlackOpaque];
NSArray *toolbarItems = [NSArray arrayWithObjects:
doneButton, nil];
[toolBar setItems:toolbarItems];
productDescription.inputView = productPicker;
productDescription.inputAccessoryView = toolBar;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self addPickerView];
}
#pragma mark - Text field delegates
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
([textField.text isEqualToString:#""]);
}
#pragma mark - Picker View Data source

return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component{
return [productListArray count];
}
#pragma mark- Picker View Delegate
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:
(NSInteger)row inComponent:(NSInteger)component{
[productDescription setText:[productListArray objectAtIndex:row]];
}
- (void)doneButton:(UIBarButtonItem *)sender{
NSLog(#"Done Touched");
[productPicker setHidden:YES];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:
(NSInteger)row forComponent:(NSInteger)component{
return [productListArray objectAtIndex:row];
}
#end

Xib file in take Textfield and set delegate with connect.
#import "YourViewController.h"
#interface YourViewController ()<UIPickerViewDataSource,UIPickerViewDelegate>
{
UIPickerView *productPicker;
NSArray *productListArray;
IBOutlet UITextField *productDescription;
}
#end
- (void)viewDidLoad
{
[super viewDidLoad];
[self addPickerView];
}
-(void)addPickerView
{
productListArray = [[NSArray alloc]initWithObjects:#"myArray",#"Rohit",#"Change",#"Your view", nil];
[productDescription setPlaceholder:#"Product Description"];
productPicker = [[UIPickerView alloc]init];
productPicker.dataSource = self;
productPicker.delegate = self;
productPicker.showsSelectionIndicator = YES;
UIToolbar* toolBar = [[UIToolbar alloc] init];
toolBar.barStyle = UIBarStyleBlack;
toolBar.translucent = YES;
toolBar.tintColor = nil;
[toolBar sizeToFit];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(doneButton:)];
[toolBar setItems:[NSArray arrayWithObjects:doneButton, nil]];
productDescription.inputView = productPicker;
productDescription.inputAccessoryView = toolBar;
}
- (IBAction)doneButton:(id)sender
{
NSLog(#"Done Touched");
[productPicker removeFromSuperview];
[productPicker resignFirstResponder];
[self.view endEditing:YES];
}

I hope this will help you great.
