How to add radio button to uitableview? - ios

Question

I added button to table view cell, i want to select one button out of all when user tap on cell
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
_radioButton = [UIButton buttonWithType:UIButtonTypeCustom];
_radioButton.frame = CGRectMake(30, 0, 30, 30);
[_radioButton setImage:[UIImage imageNamed:#"radio_empty.png"] forState:UIControlStateNormal];
[_radioButton setImage:[UIImage imageNamed:#"radio.png"] forState:UIControlStateSelected];
cell.accessoryView = _radioButton;
_radioButton.tag = indexPath.row;
}
if ([indexPath isEqual:selectedIndex])
{
_radioButton.selected = YES;
}
else
{
_radioButton.selected = NO;
}
cell.textLabel.text = [self.Option objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)theTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
selectedIndex = indexPath;
[theTableView reloadData];
//I tried this also but not working
if (_radioButton.tag == indexPath.row) {
[_radioButton setImage:[UIImage imageNamed:#"radio.png"] forState:UIControlStateSelected];
}
}
I tried a lot. But it's not working.
I want to show selected image when user tap on cell. Either if we use button or image view

Answer 1

I got the solution like this.
NSString *selectedIndex;
- (void)tableView:(UITableView *)theTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[theTableView deselectRowAtIndexPath:indexPath animated:NO];
if(indexPath.row != [selectedIndex intValue]) {
// reset the active account
selectedIndex = [#(indexPath.row) stringValue];
// tell the table to rebuild itself
[theTableView reloadData];
}
}
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
if(indexPath.row == [selectedIndex intValue]) {
cell.imageView.image = [UIImage imageNamed:#"radio.png"];
}
else {
cell.imageView.image = [UIImage imageNamed:#"radio_empty.png"];
}
cell.textLabel.text = [self.Option objectAtIndex:indexPath.row];
return cell;
}
