Skip to next UItextField - ios

Question

I have some UITextfields in a UItableView. the textfields have been subclassed in a UITableViewCell that I have created. I would lke to know how to progress down to the next cell in its respective row after the return key is pressed on the keyboard.
So if the user was to start on width, they would continue down the width colum, or if they wanted to enter height each time they hit enter they would continue down that column.
currently whats happening is if i use the width colum, it works fine but if i select a height UItextField after hitting enter it jumps over to the next width cell.
This is my code for detecting the return key.
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[[self.view viewWithTag:textField.tag+1] becomeFirstResponder];
return YES;
}
and this is what my tableview of cells looks like.
For more information this is how I add the custom celltextfields to UItextfield.
NSString *widthString = [currentFinishingDictionary objectForKey:#"w"];
if ((NSNull *) widthString != [NSNull null]) {
cell.widthTexField.text = widthString;
cell.widthTexField.delegate = self;
cell.widthTexField.tag = indexPath.row;
} else {
cell.widthTexField.text = #" ";
cell.widthTexField.delegate = self;
cell.widthTexField.tag = indexPath.row;
}
NSString *heightString = [currentFinishingDictionary objectForKey:#"h"];
if ((NSNull *) heightString != [NSNull null]) {
cell.heightTextField.text = heightString;
cell.heightTextField.delegate = self;
cell.heightTextField.tag = indexPath.row;
} else {
cell.heightTextField.text = #" ";
cell.heightTextField.delegate = self;
cell.heightTextField.tag = indexPath.row;
}

Answer 1

I think the issue might be in the way the tags are assigned to the UITextFields.
Please check if the tag values are actually what you have assumed.

Answer 2

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
[yourtextfield resignFirstResponder];
// save state, etc if necessary
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
MyCell * cell = (MyCell *)[tableView cellForRowAtIndexPath:indexPath];
self.selectedField = cell.tf; // cell.tf is a UITextField property defined on MyCell
[yourtextfield becomeFirstResponder];
}

Make sure that you have set tag to UITextField
You should try in this way:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
//[[self.view viewWithTag:textField.tag+1] becomeFirstResponder];
// Get here you cell seleted Refrecne
id obj = [cell.contentView viewWithTag:textField.tag+1];
if([obj isKindOfClass:[UITextField class]]) {
UITextField *nextField = (UITextField*)obj
[nextField becomeFirstResponder];
}
return YES;
}
Or you can use ELCTextFieldCell
It contents UITextField and UILabel in one cell. You can customizr as per your need.

Answer 4

you can use
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
UITableViewCell *cell = [self.myTableview cellForRowAtIndexPath:[NSIndexPath indexPathForRow: textField.tag+1 inSection:0]];
UITextField *tf = (UITextField*)[cell viewByTag:textField.tag+1]
[tf becomeFirstResponder];
return YES;
}

Answer 5

Did you try using collectionView instead of tableview, collection views design can be made similar to the image you added and you can add one textfield in one cell and then make first responder for width text field by doing this
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
if ( [tableView.dataSource tableView:tableView numberOfRowsInSection:0] > tag + 2)
CustomCell *cell = [self.myTableview cellForRowAtIndexPath:[NSIndexPath indexPathForRow: textField.tag+2 inSection:0]];
[cell.textField becomeFirstResponder];
}
If you wanna still persist with this design then you can do this
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
int xPosition = (int)textField.frame.origin.x;
CustomCell *cell = [self.myTableview cellForRowAtIndexPath:[NSIndexPath indexPathForRow: textField.tag+1 inSection:0]];
if((int)cell.textField1.x == xPosition)
{
[cell.textField1.x becomeFirstResponder];
}
else
{
[cell.textField2.x becomeFirstResponder];
}
}
Code is not compiled. Only logic is written.Hope it helps :)

Change your assigning tag values as below that may help you.
NSString *widthString = [currentFinishingDictionary objectForKey:#"w"];
if ((NSNull *) widthString != [NSNull null]) {
cell.widthTexField.text = widthString;
cell.widthTexField.delegate = self;
cell.widthTexField.tag = indexPath.row;
} else {
cell.widthTexField.text = #" ";
cell.widthTexField.delegate = self;
cell.widthTexField.tag = indexPath.row;
}
NSString *heightString = [currentFinishingDictionary objectForKey:#"h"];
if ((NSNull *) heightString != [NSNull null]) {
cell.heightTextField.text = heightString;
cell.heightTextField.delegate = self;
cell.heightTextField.tag = indexPath.row + 2000;
} else {
cell.heightTextField.text = #" ";
cell.heightTextField.delegate = self;
cell.heightTextField.tag = indexPath.row + 2000;
}
Now your textfields tag looks like as below and may work as you desired.
0 2000
1 2001
2 2002
3 2003
4 2004
.. ........
Now your method work properly but need to think other idea as well because this will wrong when you have 2000 cells.
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
// i.e. textField.tag == 6 then next 6 + 1 == 7
// i.e. textField.tag == 20006 then next 2006 + 1 == 2007
[[self.view viewWithTag:textField.tag+1] becomeFirstResponder];
return YES;
}
