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.
- 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.
