IOS- UITableView scroll back to top - ios

Question

i am using Custom UITableView in my project for displaying data it works fine but when i try to scroll it to bottom it doesn't stop at desired cell it always jumps to the top of the table. only shows 2-3 cells.
please suggest what to add to overcome this problem.
i tried so many codes answered in similar type of questions but they doesn't work
i uses the following codes for UITableView
newsFeedTable = [[UITableView alloc]init];
CGFloat Ytablepadding = CGRectGetMaxY(homeView.frame)+60;
CGFloat heighttable = 700;
newsFeedTable.frame = CGRectMake(0,Ytablepadding, self.view.frame.size.width, heighttable);
[self.view addSubview:newsFeedTable];
newsFeedTable.delegate=self;
newsFeedTable.dataSource= self;

Answer 1

Add this code in you viewDidload :
NSIndexPath *myIndexPath = [NSIndexPath indexPathForRow:AddYourLastIndex inSection:0];
[self.tbl_presentation selectRowAtIndexPath:myIndexPath animated:YES scrollPosition:UITableViewScrollPositionBottom];

Answer 2

UITableView is a subclass of UIScrollView, so you can also use:
[newsFeedTable scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];
Or
[newsFeedTable setContentOffset:CGPointZero animated:YES];

Answer 3

Simplest you can do is :
calling [newsFeedTable setContentOffset:CGPointMake(0, CGFLOAT_MAX)]
will do what you want.

Answer 4

You need to adjust the table view's height according to the height of the view, of which you are making subview to see the last row of the table or rather to scroll it to bottom:
newsFeedTable.frame = CGRectMake(0,Ytablepadding, self.view.frame.size.width, self.view.frame.size.height - Ytablepadding);
and to scroll it to last row on table reload/ after popping of data, scroll it programatically like this:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[newsFeedTable reloadData];
dispatch_async(dispatch_get_main_queue(), ^{
int lastRowNumber = [newsFeedTable numberOfRowsInSection:0] - 1;
NSIndexPath* ip = [NSIndexPath indexPathForRow:lastRowNumber inSection:0];
[newsFeedTable scrollToRowAtIndexPath:ip atScrollPosition:UITableViewScrollPositionTop animated:NO];
});
});
}];
