Question

I have two UITableview’s and if i select a one row in each table, the textLabel.text of that particular row should display in a single UIAlertview.

How can i combine the textLabel.textof two tables and display in one UIAlertView

Can anyone let me know how can i do this

EX: one Table view which displays A, B, C, D and one more tableView Which Shows 1,2,3,4.
This two table are from different class’s. now suppose if i press a row in table 1 i will get textLabel.text as ‘A’ and if i press table 2 i will get textLabel.text as ‘1’ now on the view if a select A in table1 and 1 in table 2 i should get a AlertView showing message as ‘A1’

Answer 1

Is not clear to me when you want your alertView shown,
but this will help you

you need to have a property for placing the text of your labels

so on your .h

@ interface MyViewController :UIViewController {
 NSString *_stringTable1;
    NSString *_stringTable2;
}

@property (nonatomic, retain)  NSString *stringTable1;
@property (nonatomic, retain)  NSString *stringTable2;

on your .m

@synthesize stringTable1 = _stringTable1; 
@synthesize stringTable2 = _stringTable2; 
- (void) dealloc{
[_stringTable1 release];
[_stringTable2 release];
    [super dealloc];
}

so on your table delegate

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {

    if (tableView == table1) {
    self.stringTable1  = [myArray1 objectAtIndex: indexPath.row];   
    //call uiAlert, and place the stringTable1 on your message
 }
    if (tableView == table2) {
    self.stringTable2  = [myArray2 objectAtIndex: indexPath.row];   
        //call uiAlert, and place the stringTable2 on your message

 }

    }

when you call your uiAlertView, for the message you can just show them togheter like

 [NSString stringWithFormat:@"%@ %@", self.stringTable1, self.stringTable2];
