Get input from UITextField

I'm doing a programatic UI for my iOS app, and I have these two UITextFields. When the client opens the app, they'll select the two fields and give some input, after that, how do I deselect the UITextFields? Because if you tap or scroll somewhere else on the screen, the keyboard stays on the screen - it doesn't retract like the expected behavior.

So I guess my question is how do you submit a UITextField without a nib or storyboard?

Here's the relevant part of viewDidLoad, with the two UITextFields: 

UITextField *loginField = [[UITextField alloc] initWithFrame:mistarFrame];
loginField.backgroundColor = [UIColor clearColor];
loginField.textColor = [UIColor whiteColor];
loginField.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:20];
loginField.borderStyle = UITextBorderStyleNone;
loginField.autocorrectionType = UITextAutocorrectionTypeNo;
loginField.autocapitalizationType = UITextAutocapitalizationTypeNone;
loginField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
loginField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"Student ID" attributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]}];
[header addSubview:loginField];

UITextField *passwordField = [[UITextField alloc] initWithFrame:CGRectMake(mistarFrame.origin.x, (mistarFrame.origin.y + iconHeight), mistarFrame.size.width, mistarFrame.size.height)];
passwordField.backgroundColor = [UIColor clearColor];
passwordField.textColor = [UIColor whiteColor];
passwordField.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:20];
passwordField.borderStyle = UITextBorderStyleNone;
passwordField.autocorrectionType = UITextAutocorrectionTypeNo;
passwordField.autocapitalizationType = UITextAutocapitalizationTypeNone;
passwordField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
passwordField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"Password" attributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]}];
passwordField.secureTextEntry = YES;
[header addSubview:passwordField];

Also you can conform to UITextFieldDelegate protocol and set

loginField.delegate = self;
passwordField.delegate = self;

and then implement

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    if ([loginField.text isEqualToString:@""] == NO && [passwordField.text isEqualToString:@""] == NO) {
        //submit...
    }
    return YES;
}

That's if you want to submit by pressing return on the keyboard.

Here's a sample implementation file...

#import "ViewController.h"

@interface ViewController () <UITextFieldDelegate>

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
UITextField *tf = [[UITextField alloc] initWithFrame:CGRectMake(10, 30, 100, 25)];
    [self.view addSubview:tf];
    tf.delegate = self;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    if ([textField.text isEqualToString:@""] == NO) {
        NSLog(@"Submit");
    }
    return YES;
 }

@end

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    [loginField resignFirstResponder];
    //..
}

Try this.

I would suggest adding a UIGestureRecognizer to your view where the UITextViews are located and hook up a "hide keyboard event" to the tap action.

For example, if the UITextViews are in the view of a UIViewController:

- (void)viewDidLoad {
    [super viewDidLoad];
    UITapGestureRecognizer *screenTapped = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                               action:@selector(dismissKeyboard)];
    screenTapped.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:screenTapped];
}

- (void)dismissKeyboard {
    [self.view endEditing:YES];
}
