IOS 7 how to use UITableView scrollToRowAtIndexPath

I'm new to IOS 7 and I'm made a test application where I want to use scrollToRowAtIndexPath when a left swipe is detected. The swipe is detected but I'm struggling with the "self" definition. I get the error No visible @interface for 'SimpleTableViewController'

- (void)handleSwipeLeft:(UISwipeGestureRecognizer *)recognizer
{
    NSLog(@"%u = %d",  recognizer.direction,recognizer.state);

     // jump to section 0 row 20 when leftswipe is dectected
    NSIndexPath *newIndexPath = [NSIndexPath indexPathForRow:20 inSection:0];

    [self.tableView scrollToRowAtIndexPath:newIndexPath atScrollPosition:UITableViewScrollPositionTop animated:NO];

}

I can send the complete source code if you want or you can download it here:

www.auditext.com/xintax/SimpleTable.zip

Using self.tableView gives message Property 'tableView' not found on object of type 'SimpleTableViewController' –

It works now I have added this line to my viewcontroller.h: `@property (strong, nonatomic) IBOutlet UITableView *myview;

NSIndexPath *loc = [NSIndexPath indexPathForRow:row inSection:section];

[self.myview scrollToRowAtIndexPath:loc atScrollPosition:UITableViewScrollPositionBottom animated:YES]; `

Why you are getting this error, Because scrollToRowAtIndexPath is a UITableView method Refer this.

And also you are calling the same method with self which indicate you class name SimpleTableViewController. So you are getting this error No visible @interface for 'SimpleTableViewController'. Just call this method with self.tableView instead of using self.

Note:-

1) Declare property inside your header file SimpleTableViewController @property(nonatomic,strong)UITableView *tableView

2) No need to explicitly include the synthesize, if you are using Xcode version above than 4.

You need to point to the UItableView

[self.tableView scrollToRowAtIndexPath:newIndexPath 
                      atScrollPosition:UITableViewScrollPositionTop 
                              animated:NO];

You just need to call is self.tableView instead of self. self refers to the TableViewController and self.tableView to it's tableView.
