If you don't want to specify an object just use nil.

[NSThread detachNewThreadSelector:@selector(method:) toTarget:self withObject:nil];

If you need to pass an object to the selector it would look something like this.

Here I'm passing a string to the method "setText".

NSString *string = @"hello world!";
 [NSThread detachNewThreadSelector:@selector(setText:) toTarget:self withObject:string];


-(void)setText:(NSString *)string {
    [UITextField setText:string]; 
}
