Mirror text from UITextField to inputAccessoryView - UIToolBar to text in UITextField to navigationController.toolbar

In my application, I have a UITextField in the navigationController navigation bar.

#import "ViewController.h"

@interface ViewController ()

@property (nonatomic,strong) NSArray *toolBarButtonItems;
@property (nonatomic,strong) UITextField *textField;
@property (nonatomic,strong) UITextField *textField2;

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.textField = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 60, 40)];
    self.textField.delegate = self;
    self.textField.borderStyle = UITextBorderStyleRoundedRect;

    UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc]initWithCustomView:self.textField];

    self.toolBarButtonItems = @[flexibleSpace,barButtonItem,flexibleSpace];

    self.toolbarItems = self.toolBarButtonItems;
    self.navigationController.toolbar.barTintColor = [UIColor blueColor];

    [self.navigationController setToolbarHidden:NO animated:NO];
}

When I click on the text field, the keyboard opens and I create a new inputAccessoryView toolbar with a different text field.

-(UIToolbar *)addToolBar{
    UIToolbar *toolbar = [[UIToolbar alloc]initWithFrame:self.navigationController.toolbar.frame];
    toolbar.barTintColor = [UIColor darkGrayColor];

    self.textField2 = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 60, 40)];
    self.textField2.delegate = self;
    self.textField2.borderStyle = UITextBorderStyleRoundedRect;

    UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc]initWithCustomView:self.textField2];

    [toolbar setItems:@[flexibleSpace,barButtonItem,flexibleSpace]];
    return toolbar;
}

The idea is to change the firstResponder from textField to inputAccessoryView, so I can see what I'm editing. The reason I am doing this is because I cannot scroll the navigation bar above the keyboard, and I want to see the text I am editing.

-(void)textFieldDidBeginEditing:(UITextField *)textField{
    textField.inputAccessoryView = [self addToolBar];

    if(self.textField2.isFirstResponder != NO){
        [self.textField2 becomeFirstResponder];
    }
}

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    self.textField.text = self.textField2.text;
    return YES;
}
