Text Field General

Text fields are for single line text.  For multi line text use Text View

Delegates

textFieldShouldReturn

Keyboard return key pressed

Example Of Use

Declaring in #ViewController.h file

        IBOutlet UITextField *MyTextFieldName;

Releasing in #ViewController.m file

//********** VIEW DID UNLOAD **********
- (void)viewDidUnload
{
        [super viewDidUnload];

        [MyTextFieldName release];
        MyTextFieldName = nil;
}

//********** DEALLOC **********
- (void)dealloc
{
        [MyTextFieldName release];

        [super dealloc];
}

Connecting in Interface Builder

Add the text filed to the view
Right click Files Owner
Drag the outlet to your text field

Storing Values Entered In A Text Field

        [SomeIntVariable:[[SomeTextField text] intValue]];

Dismissing The Keyboard & Responding To Input

Open the XIB.
For each of the text fields, right click and drag the ‘delegate’ circle to ‘Files Owner’

Then in #ViewController.m:

//********** TEXT FIELD SHOULD RETURN **********
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
        [textField resignFirstResponder];
        return YES;
}

If you have any methods in #ViewController.m that want to ensure the keyboard is removed:

//********** VIEW WILL DISAPPEAR **********
- (void)viewWillDisappear:(BOOL)animated
{
        [super viewWillDisappear:animated];

        [[self view] endEditing:YES];           //Ensure keyboard is removed
}
