Set up a class that conforms to the UITextFieldDelegate protocol and make the delegate of your text fields an instance of this class. Implement the method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField

As follows:

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

Hi i found it out so the point with textfields is to add this lines at viewdidload:

textFieldOne.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
textFieldTwo.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
...

And this implement method :

-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {

    if (theTextField == textFieldOne) {
        [textFieldOne resignFirstResponder];
    }
...
}

U can use this method to hide the keyboard by clicking any where in the view

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

After quite a bit of time hunting down something that makes sense, this is what I put together and it worked like a charm.

}

// This part is more dynamic as it closes any text field when pressing return.

-(void)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
}
