Answer 1

You change the UITableViewCell accessory type
As for what is selected, you use the above property in tableView:didSelectRowAtIndexPath.

Answer 2

For the French/English section, you'll need to have one checked by default I assume.
In your cellForRowAtIndexPath:
if([cell.textLabel.text isEqualToString:#"English"])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
Then, whenever the cell is tapped, you'll need to figure out with one has been tapped, and then uncheck the other.
in your didSelectRowAtIndexPath
if(indexPath.section ==0 && indexPath.row ==0) {
UITableViewCell * otherCell = [tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0]];
otherCell.accessoryType = UITableViewCellAccessoryNone;
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else if(indexPath.section ==0 && indexPath.row ==1) {
UITableViewCell * otherCell = [tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
otherCell.accessoryType = UITableViewCellAccessoryNone;
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}

Answer 3

You can mark or unmark row using
cell.accessoryType = UITableViewCellAccessoryCheckmark;
cell.accessoryType = UITableViewCellAccessoryNone;
You add above method in didSelectRowAtIndexPath, manage all checks in array and reload the data.

Answer 4

You can check or uncheck the view, that is great, but where are you saving the model? What property are you using to save the information about what language is being selected?
I would suggest that you have some sort of enumerated data type that holds the language you are selecting and include it in you .h file:
enum language {english, french};
#interface TesterProjectViewController : UIViewController
{
enum language selectedLanguage;
}
Next I would select a language on your viewDidLoad: as your default language, or use NSUserDefaults to select the language they selected last.
- (void)viewDidLoad
{
[super viewDidLoad];
self->selectedLanguage = english;
}
Then, I would use my UITableViewDelegate and UITableViewDataSource functions to keep up with which language needs to be selected, and which UITableViewCell needs to have the accessory view:
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.section==0)
{
switch (indexPath.row) {
case 0:
self->selectedLanguage = english;
break;
case 1:
self->selectedLanguage = french;
break;
default:
break;
}
}
[theTableView reloadData];
}
The didSelectRowAtIndexPath: method is used to set which language you are using in your MODEL. Then the cellForRowAtIndexPath: method is used to set your VIEW to match your MODEL. You may wish to go ahead and set the check mark in your didSelectRowAtIndexPath:, but I prefer to keep it in the cellForRowAtIndexPath: so that it is always correct if my data gets reloaded, like so:
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *theCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
// You may set up the cell differently or do whatever setup you need here:
if(indexPath.section==0)
{
if(self->selectedLanguage == english && indexPath.row==0)
theCell.accessoryType = UITableViewCellAccessoryCheckmark;
else if(self->selectedLanguage == french && indexPath.row==1)
theCell.accessoryType = UITableViewCellAccessoryCheckmark;
else
theCell.accessoryType = UITableViewCellAccessoryNone;
}
//More cell setup can go here, or setup cells for different rows/sections.
return theCell;
}
Also, as others have noted, I would use UISwitch for the notification selections at the bottom as they are not "radio" type selections, but rather each selection is an on/off type selection.
I hope this has helped you!

use this code :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
}else{
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
}
- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypeForRowWithIndexPath:(NSIndexPath
*)indexPath {
//add your own code to set the cell accesory type.
return UITableViewCellAccessoryNone;
}
