EditingUITableView

Making UITableView based view controllers that need multiple UITextFields for editing a breeze.

There are a number of problems working with UITableViews whenever UITextField elements are involved:

Moving data from the text fields
Jumping from current responder to the next
Handling the keyboard properly to resize the table and move content to a visible area

This set of classes are designed to make these tasks easy. Here's an example of how to do this.

Example Usage

Copy all the files from UITableViewTextFieldAdditions into your project.

In your UIViewController which contains your UITableView:

Include headers

#import "UITableView+TextFieldAdditions.h"
#import "EditableTableViewCell.h"
end

Enable auto-keyboard handling for our UITableView

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[self tableView] beginWatchingForKeyboardStateChanges];
}

- (void)dealloc 
{
		[[self tableView] endWatchingForKeyboardStateChanges];
}

Return editable cells (snippet)

NSString * const kCellID = @"emailCell";
EditableTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: kCellID];
if( !cell )
{
	cell = [[EditableTableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier: kCellID];
}

cell.textLabel.text = NSLocalizedString( @"Email", @"Email" );

cell.textField.placeholder = NSLocalizedString( @"john@me.com", @"john@me.com" );
cell.textField.delegate = self;
cell.textField.returnKeyType = UIReturnKeyNext;
cell.textField.keyboardType = UIKeyboardTypeEmailAddress;
cell.textField.autocapitalizationType = UITextAutocapitalizationTypeNone;
cell.textField.autocorrectionType = UITextAutocorrectionTypeNo;
cell.textField.text = [self username];

Update our data from the UITextFields as the user types and handle our "Next" logic

-(BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
	NSString *text = [[textField text] stringByReplacingCharactersInRange: range withString: string];
	NSIndexPath *indexPath = [[self tableView] indexPathForFirstResponder];
	if( [indexPath row] == kUsernameRow )
	{
		self.username = text;
	}
	return YES;
}

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

That's it! Checkout the sample code for further details.
