Question

My code follows as:

NSArray *vis = [tableView1 visibleCells];
    NSLog (@"vis %@", vis);

And I get:

2012-07-04 21:16:44.564 xxx[1933:12e03] vis (
    "<UITableViewCell: 0xb2dcc80; frame = (0 0; 320 80); text = 'xxx1'; autoresize = W; layer = <CALayer: 0xb2dcd60>>",
    "<UITableViewCell: 0x635ea10; frame = (0 80; 320 80); text = 'xxx2'; autoresize = W; layer = <CALayer: 0x6353620>>",
    "<UITableViewCell: 0xb2ddca0; frame = (0 160; 320 80); text = 'xxx3'; autoresize = W; layer = <CALayer: 0xb2ddc70>>",
    "<UITableViewCell: 0x635f7d0; frame = (0 240; 320 80); text = 'xxx4'; autoresize = W; layer = <CALayer: 0x635f650>>"

When I write:

NSString *aText = [vis objectAtIndex:0];
NSLog (@"aText %@", aText);

I get invariably a warning:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableArray objectAtIndex:]: index 0 beyond bounds for empty array'

Is this a kind of multidimensional array? If yes, how can I extract only text?

Answer 1

The array returned by visibleCells contains UITableViewCell objects, and not NSString objects. You can see that in the output of your NSLog(@"vis %@", vis);.

To get the strings, you’d need to ask the UITableViewCells for them.

In other words:

NSString *aText = [[[vis objectAtIndex:0] textLabel] text];
