Question

I have a UITableview in my xcode project.In that Comments are listed.How can i focus on a last cell of my TableView with scrolling animation?

Answer 1

Below method will find the last index of you table view and will focus to that cell with an animation

-(void)goToBottom
{
    NSIndexPath *lastIndexPath = [self lastIndexPath];

    [<YOUR TABLE VIEW> scrollToRowAtIndexPath:lastIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}

Code to find the last index of your tableview.

-(NSIndexPath *)lastIndexPath
{
    NSInteger lastSectionIndex = MAX(0, [<YOUR TABLE VIEW> numberOfSections] - 1);
    NSInteger lastRowIndex = MAX(0, [<YOUR TABLE VIEW> numberOfRowsInSection:lastSectionIndex] - 1);
    return [NSIndexPath indexPathForRow:lastRowIndex inSection:lastSectionIndex];
}

Add this code somewhere in your view controller

[self performSelector:@selector(goToBottom) withObject:nil afterDelay:1.0];
