Selecting Cell in Table IOS - ios

Question

I am trying to create a method that changes the string object "tableColorName" to the cell selected. The tableData NSArray consists of object: "red","blue","green". I want to save the string "tableColorName" to redColor if red is selected, blueColor if blue, greenColor if green. After the cell is selected I want the viewController to go back to the root. I appreciate your help in advance:
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int theRow = indexPath.row;
NSString *tableColorName;
tableColorName = [[NSString alloc] initWithString:([_tableData [theRow] stringValue],#"Color")];
[self.navigationController popToRootViewControllerAnimated:YES];
}

Answer 1

//first of all take one NSArray and
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.colorNames = [[NSArray alloc] initWithObjects:#"Red", #"Green",
#"Blue", #"Indigo", #"Violet", nil];
}
// Implement Table method
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.colorNames count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
self.navigationItem.title=#"Colors";
UIImage *cellImage = [UIImage imageNamed:#"a.png"];
cell.imageView.image = cellImage;
NSString *colorString = [self.colorNames objectAtIndex: [indexPath row]];
cell.textLabel.text = colorString;
NSString *subtitle = [NSString stringWithString: #"All about the color "];
subtitle = [subtitle stringByAppendingFormat:colorString];
cell.detailTextLabel.text = subtitle;
return cell;
}
- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath
{
int idx = indexPath.row;
obj.lbl.text=[#"You select "stringByAppendingString:[colorNames objectAtIndex:idx]];
[self popToViewController animated:YES];
}

Try this ::
NSArray *arr;
NSString *tableColorName; // Use in AppDelegate
- (void)viewDidLoad
{
arr = [[NSArray alloc] initWithObjects:#"Red", #"Green", #"Blue", nil];
}
Table View Methods ::
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.title.text = [NSString stringWithFormat:#"%#", [arr objectAtIndex:indexPath.row]];
return cell;
}
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
app.tableColorName = [NSString StringWithFormat:#"%# Color", [arr objectAtIndex:indexPath.row]];
[self.navigationController popToRootViewControllerAnimated:YES];
}
Then, access by app.tableColorName whenever you want to display.
Thanks.

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
//do whatever with the selected cell.
//go back to the root
}
