Can I use a background thread to parse data?

Question

I\'m using chcsvparser to parse data from a csv file on my apps launch. It\'s taking way too long to startup on main thread so I was thinking of doing this on the backgroun

Answer 1

You can always pass objects between threads.

Use the following code to create a thread and pass the object to it.

[NSThread detachNewThreadSelector:@selector(myThreadSelector:) toTarget:self withObject:myObject];

After the thread function is over you can pass the data back to the main thread using

[self performSelectorOnMainThread:@selector(myMainSelector:) withObject:myReturnObject waitUntilDone:NO];

you can pass the output NSArray from the parser to myMainSelector: and reload the tableview in it.

-(void)myMainSelector:(id)sender
{
    NSArray *arr = sender;
    tableDataArray = [NSArray arrayWithArray:arr];
    [yourTableView reloadData];
}

You can show an activity indicator while you are in the thread method.
