iOS UItableview scrollToRowAtIndexPath not working anymore

Question

This morning I just installed new Xcode which includes iOS 6.

I have a table view loaded with a plist file containing chapters and lines. Chapters define the section

Answer 1

After iOS7 the property automaticallyAdjustsScrollViewInsets of UIViewController default is YES. It will cause system to adjust the contentOffset of tableView when the view controller pushed. Even you call [self.tableView scrollToRowAtIndexPath:rowIndexPath atScrollPosition:UITableViewScrollPositionNone animated:NO]; in the viewWillAppear. The contentOffset also will be changed by system after viewWillAppear. So my solution is:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.automaticallyAdjustsScrollViewInsets = NO;

    /// any other codes
}

- (void)viewWillLayoutSubviews {
    self.tableView.contentInset = UIEdgeInsetsMake(self.topLayoutGuide.length, 0, 0, 0);
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    // change tableView data source

    [self.tableView reloadData];
     NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[self.dataSourceArray count] - 1 inSection:0];
    [self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionNone animated:NO];
}
