Pagination UITableView, setting the content offset

Question

I am trying to implement pagination in my UITableView. My cells heights are pretty much fullscreen, code here:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

    return  ([[UIScreen mainScreen] bounds].size.height) - (self.navigationController.navigationBar.frame.size.height)-20;

}

I have set paging enabled in the interface builder however the offset is slightly wrong. I guess this is because it uses the size of the window frame as its offset. Is there anyway I can adjust this to match my table cell heights? Any tips would be really appreciated.

Answer 1

If TabBar or bottom of the view is covering the TableView cells then use following code in -viewDidLoad: method

self.edgesForExtendedLayout = UIRectEdgeAll;
// self.tableView.contentInset = UIEdgeInsetsMake(0.0f, 0.0f, CGRectGetHeight(self.tabBarController.tabBar.frame), 0.0f);
self.tableView.contentInset = UIEdgeInsetsMake(0.0f, 0.0f, 75.0f, 0.0f);

If you want to present the top of your table view when it appears the use following code in -viewWillAppear: method

[self.tableView reloadData];
self.tableView.contentOffset = CGPointMake(0, 0 - self.tableView.contentInset.top);

Hope you find your answer
