Keyboard Configurations/Problems

[vilisei]

I am making a universal tabbed application, and one of the tabs is a login screen. How do I make the keyboard disappear when the user tabs outside the box or taps the sign in button? Also how do I link the next button to the password box as in when you type the username, there is a next button instead of a return button, but it won't go to the next field. I have tried other forums but they give me a stop sign (icon) error.

1. David Linsin - Dismiss Keyboard on Tap "Outside"

2. Use the textfield delegate method, something like textFieldDidReturn. Make the second UITextfield the first responder and relieve the first one of its duties.

Where would I place that code? All I did was add a textfield (as in the picture) from the toolbox, I didn't write it in code. Here is all the code (except for the green stuff at the top):

PHP Code:

#import "FirstViewController.h"

@implementation FirstViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"Account", @"Account");
        self.tabBarItem.image = [UIImage imageNamed:@"first"];
    }
    return self;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

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

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

@end

Just setup an IBOutlet and place the code in your .m file.

[vilisei]

I still don't get it. Does it matter in what order to place it? Like before or after the (code below) or before/after what?

PHP Code:

#pragma mark - View lifecycle

Make IBOutlets for the text fields. then hook them up in IB. While in IB set the tag's of the text fields to 0 and 1 (you only have 2 fields right?) Then implement the textFieldShouldReturn method. That can be placed anywhere inside the .m for that view controller you want - it is a new method unto itself and doesnt need "calling" from elsewhere. In the method set an int to the textfield.tag and add 1 to it. Then an if statement to check when it has reached the highest tag it should return YES;.

For dismissing the keyboard on a click (i.e. background click) create an IBAction (i call mine background click :P) and in that method call "resignFirstResponder" on each of the text fields.

Post back if you need that clearing up a bit, rather not spoon feed the code if you can figure it out

[vilisei]

What do you mean by IBOutlets? Is it like a new object or what? Also I am using Xcode 4 so I don't have Interface Builder.

[Domele]

Xcode 4 does have Interace Builder, it's just integrated into Xcode. IBOutlets are a way to reference objects built in Interface Builder. You declare them in your header file like so

IBOutlet UITextField *myTextField;

Then you go into Interface Builder, select the file owner, go to the last tab in properties, and click and drag the circle to the object.

I found out how to make the keyboard disappear when you tap outside, but how do I make the next button link to the password box and the done button on the keyboard make the keyboard dissappear? Code for dismissing the keyboard when tapping outside:

PHP Code:

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    for (UIView* view in self.view.subviews)
    {
        if ([view isKindOfClass:[UITextField class]]) {
            [view resignFirstResponder];
        }
        
        if ([view isKindOfClass:[UITextView class]]) {
            [view resignFirstResponder];
        }
    }
}

Dismissing keyboard with done button:

//in viewdidload

//Field is an IBOutlet
	
	Field.delegate = self;
	Field.returnKeyType = UIReturnKeyDone;

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