Get the index path of last row in UITableView

Question

I have a UITableView with 1 section and numberOfRows: from NSMutableArray .

What I want here is that whenever UITableView appears the scroll view must scroll to last row.

For this I want indexPath of last row. How to get it?

I know this question is answered many times. But none of those approaches worked for me.

Here is the code I tried

-(NSIndexPath*)lastIndexPath{
     NSInteger sectionsAmount = [myTableView numberOfSections];
     NSInteger rowsAmount = [myTableView numberOfRowsInSection:sectionsAmount-1];
     NSIndexPath *lastIndexPath = [NSIndexPath indexPathForRow:(rowsAmount - 1) inSection:(sectionsAmount - 1)];
     return lastIndexPath;
 }

Answer 1

由于您只有一个部分，因此yu可以找到带有

[NSIndexPath indexPathForRow:[yourArray count]-1 inSection:0]

Answer 2

scrollToRowAtIndexPath should work.

In viewWillAppear , try this:

[theTableView reloadData];    
NSIndexPath* ip = [NSIndexPath indexPathForRow:rowNumberHere inSection:sectionNumberHere];
[theTableView scrollToRowAtIndexPath:ip atScrollPosition:UITableViewScrollPositionTop animated:NO];
