Moving to next textField inside an UITableView

I have a tableView full of sub-classed textFields. Below is how i created them:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdentifier = kOddCellIdentifier;
CustomCell01 *oddCell = (CustomCell01 *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
oddCell.myTextfield.delegate=self;
oddCell.myTextfield.tag = indexPath.row;
oddCell.myTextfield.text=[[self.Page01dataArray objectAtIndex:indexPath.row]objectForKey:@"value"];
bool editable = [[[self.Page01dataArray objectAtIndex:indexPath.row] objectForKey:@"editable"] boolValue];
if (editable==true) {
oddCell.myTextfield.textColor=[UIColor redColor];
} else {
oddCell.myTextfield.textColor=[UIColor blackColor];
[oddCell.myTextfield setBorderStyle:UITextBorderStyleNone];
oddCell.myTextfield.enabled=NO;
}
[oddCell.myTextfield addTarget:self action:@selector(updateField:) forControlEvents:UIControlEventEditingDidEnd];
return oddCell;
}
I do not know how to move to the next textfield when the user taps on the "Next" button. Normally i should make the next textfield the first responder however since all my textfields have the same name "myTextfield", i do not know how to do it. Please help!
Soluzione 2
I finally managed to find out a solution by creating an array in cellForRowAtIndexPath
[nextTFarray addObject:oddCell.myTextfield];
and then:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
int i=[nextTFarray count];
int x=textField.tag+1;
UITextField *nextTextField = (UITextField *)[nextTFarray objectAtIndex:x];
if (x<i-1) {
[nextTextField becomeFirstResponder];
} else {
[textField resignFirstResponder];
}
return YES;
}

In cellForRowAtIndexPath
, set the name to something like "myTextfield-<row>"
. Then you can parse that and know what the prev/next fields are. You are already setting myTextfield.tag
to indexPath.row
so you won't even have to parse the name. You know the previous and next fields are "myTextfield-<tag-1>"
and "myTextfield-<tag+1>"
, respectively.
