ios - Perform addition of values from each cell of tableview -

i working on shopping app add items in cart. have show sub total amount need perform addition of price of each item in table.

how can pick values each cell , add them?

below code tableview:

#pragma mark - table view data source  - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {     return  [cartlist count]; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     nsdictionary *celldata = [[[cartlist objectatindex:indexpath.row] valueforkey:@"addtocartproductimagemodel"] firstobject];     nsstring *image=[celldata valueforkey:@"productimg"];     nsstring *urlstring = [nsstring stringwithformat:@"http://dealnxt.com/areas/user/productimage/%@", image];     nsurl *url = [nsurl urlwithstring:urlstring];     nsdata *data = [nsdata datawithcontentsofurl:url];      nsstring *celldata = [[cartlist objectatindex:indexpath.row] valueforkey:@"shortdescription"];      static nsstring *simpletableidentifier = @"cell";     carttableviewcell *cell = (carttableviewcell *)[tableview dequeuereusablecellwithidentifier:simpletableidentifier forindexpath: indexpath];     cell.proimg.image=[uiimage imagewithdata:data];     cell.prlbl.linebreakmode = nslinebreakbywordwrapping;     cell.prlbl.numberoflines = 0;     cell.prlbl.text=celldata;     cell.prprice.text=[nsstring stringwithformat: @"₹%@",[[cartlist objectatindex:indexpath.row] valueforkey:@"price"]];     cell.quantity.text=[nsstring stringwithformat:@"%@",[[cartlist objectatindex:indexpath.row] valueforkey:@"quantity"]];     nsstring *string =[nsstring stringwithformat: @"%@",[[cartlist objectatindex:indexpath.row] valueforkey:@"price"]];   int value = [string intvalue];    (int i=0; i<=[cartlist count]; i++) {      int total=0;     total=+value;     nslog(@"total:%d",total); }      return cell; } 

where prprice need add.

    //  write code somewhere fill cartlist variable value.  float tot; (int = 0; < [cartlist count]; i++) {  tot = tot +  [[[cartlist objectatindex:i] valueforkey:@"price"] floatvalue];     // stuff... } nslog("total cost : ₹ %.2f",tot);
