create checkbox inside uitableviewcell - objective-c

Question

I have uitaleviewcell with different sections and rows, I want to have checkbox cell that you can see in the picture
my question is how can I create checkbox in uitableviewcells?(I used storyboard)

Answer 1

Use UISwitch and in the property inspector, set an empty box image for normal state and a checked box image for highlighted state. However checkbox behaviour is represented by switches in ios, a checkbox has a very small hit area and might pose a usabilty problem for your users, especially when they are close to each other as in the image you provided.
UISwitch Reference

Answer 2

Each checkbox cell should be a Custom TableViewCell. Then simply drop an ImageView and a Label in the TableViewCell and use didSelectRowAtIndex: to toggle the image between checked/unchecked.

Answer 3

You need two images for imageView of cell
#define SELECTED_ROW #"selectedRowImage.png" // CheckBox with Selected sign png
#define NOT_SELECTED_ROW #"notSelectedRowImage.png" // Empty CheckBox png
// listSelected is array of indexes selected
in ViewDidLoad:
NSMutableArray *listSelected = [[NSMutableArray alloc]init];
// CellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"select";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: cellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
if ([self checkIfIndexPathAlreadySelected:indexPath])
cell.tag = 1;
else cell.tag = 0;
if(cell.tag == 0)
cell.imageView.image = [UIImage imageNamed:NOT_SELECTED_ROW];
else
cell.imageView.image = [UIImage imageNamed:SELECTED_ROW];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if(cell.tag == 0)
{
cell.tag = 1;
[self.listSelected addObject:indexPath]];
cell.imageView.image = [UIImage imageNamed:SELECTED_ROW];
}
else if(cell.tag == 1)
{
cell.tag = 0;
[self.medicineIndexArray removeObject:indexPath];
cell.imageView.image = [UIImage imageNamed:NOT_SELECTED_ROW];
}
}
- (BOOL)checkIfIndexPathAlreadySelected:(NSIndexPath *)indexPath
{
if([self.listSelected containsObject:indexPath])
return YES;
else
return NO;
}
