Update value in UITableViewCell from another methd iOS - ios

Question

I have method called
- (void)redeemOfferService
{
// in this method i want access OffersBoughtCellTableViewCell,
how to access tableview cell here ?
// want to update selected tableview cell values
// here i am getting selected cell details in selectedOfferBoughtObj which
is actually NSObject in that i am having five string values
i want show that values in my tableview cell how can i ?
//
}
The above method is calling from
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex
{
if(alertView.tag == 10)
{
if(buttonIndex == 0)
{
[self redeemOfferService];
}
}
}
and this method is calling when i tap on tableview cell i.e.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UIAlertView *logoutAlert = [[UIAlertView alloc]initWithTitle:#"Are you sure you want to redeem?" message:nil delegate:self cancelButtonTitle:#"Yes" otherButtonTitles:#"No", nil];
logoutAlert.tag = 10;
[logoutAlert show];
}
i know there is way, we can send sender from button click but i want in above scenario.

Answer 1

Use a global variable in your class NSIndexPath type and on selected store your selected indexpath
NSIndexPath *selectedIndexPath; //declare it as a global
After assign selected value in didSelect
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath
{
UIAlertView *logoutAlert = [[UIAlertView alloc]initWithTitle:#"Are you sure you want to redeem?" message:nil delegate:self cancelButtonTitle:#"Yes" otherButtonTitles:#"No", nil];
logoutAlert.tag = 10;
[logoutAlert show];
selectedIndexPath = indexPath;
}
And change like this in your function
- (void)redeemOfferService
{
OffersBoughtCellTableViewCell * _selectedCell = [offersTableView cellForRowAtIndexPath:selectedIndexPath]; //Now Its your selected cell Try this .
}
It will work fine try once and revert back

Answer 2

You are surely updating the tableview from some NSMutableArray, meaning you are filling up your tableview with this array.
In your redeemOfferService method, change the value of that Object inside the NSMutableArray with which you are filling up the tableview.
Then call [self.tableviewName reloadData]

Answer 3

You can use the indexPathForSelectedRow property of UITableView to access selected indexPath.
- (void)redeemOfferService
{
OffersBoughtCellTableViewCell *selectedCell = (OffersBoughtCellTableViewCell *)[tableViewObject cellForRowAtIndexPath:offersTableView.indexPathForSelectedRow];
}
This gives you the selected OffersBoughtCellTableViewCell
