Single Text from two different UITableView - iphone

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];

Answer 2

//Combine two string in one string on the tap of second table cell tap event...
//Use following code in didSelectRowAtIndexPath method..and enjoy...
NSString *tempstring = [[NSString alloc]init];
tempstring =yourlable.text;// your cell label...
if (textField.tag == 1) {
NSUserDefaults *stringsaver = [NSUserDefaults standardUserDefaults];
if([stringsaver objectForKey:#"stringsaver"]== nil)
{
[stringsaver setObject:tempstring forKey:#"stringsaver"];
}
else
{
NSString *combinedstring = [stringsaver objectForKey:#"stringsaver"];
//NSLog(#"==%#",combinedstring);
UIAlertView *alertdata = [[UIAlertView alloc]
initWithTitle:#"Your Title"
message:combinedstring
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertdata show];
[alertdata release];
[stringsaver removeObjectForKey:#"stringsaver"];
}

Try this-
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell * cell1 = [tableView cellForRowAtIndexPath:indexPath];
// get here the instance of otherTableView.
UITableViewCell * cell2 = [otherTableView cellForRowAtIndexPath:indexPath];
UILabel *Title1 = (UILabel *)[cell1 viewWithTag:1]; //for it you need to make the label with Tag 1
UILabel *Title2 = (UILabel *)[cell2 viewWithTag:1]; //for it you need to make the label with Tag 1
NSString * str = [NSString stringWithFormat:#"%# %#",[Title1 text],[Title2 text]];
//fire the alert
UIAlertView *alertdata = [[UIAlertView alloc]
initWithTitle:#"Your Title"
message:str
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertdata show];
}
