How to make return key on iPhone make keyboard disappear?

Question

I have two UITextFields (e.g. username and password) but I cannot get rid of the keyboard when pressing the return key on the keyboard. How can I do this?

Answer 1

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

.h

//
//  ViewController.h
//  demoKeyboardScrolling
//
//  Created by Chris Cantley on 11/14/13.

//

#import 

@interface ViewController : UIViewController 

// Connect your text field to this the below property.
@property (weak, nonatomic) IBOutlet UITextField *theTextField;

@end

.m

//
//  ViewController.m
//  demoKeyboardScrolling
//
//  Created by Chris Cantley on 11/14/13.
//  Copyright (c) 2013 Chris Cantley. All rights reserved.
//

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController



- (void)viewDidLoad
{
    [super viewDidLoad];
    // _theTextField is the name of the parameter designated in the .h file. 
    _theTextField.returnKeyType = UIReturnKeyDone;
    [_theTextField setDelegate:self];

}

// This part is more dynamic as it closes the keyboard regardless of what text field 
// is being used when pressing return.  
// You might want to control every single text field separately but that isn't 
// what this code do.
-(void)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
}


@end

Hope this helps!
