UICollectionView automatically scroll to bottom when screen loads

Question

I\'m trying to figure out how to scroll all the way to the bottom of a UICollectionView when the screen first loads. I\'m able to scroll to the bottom when the status bar is tou

Answer 1

For me, i found next solution:

call reloadData in CollectionView, and make dcg on main to scroll.

 __weak typeof(self) wSelf = self;

 [wSelf.cv reloadData];
 dispatch_async(dispatch_get_main_queue(), ^{
 NSLog(@"HeightGCD:%@", @(wSelf.cv.contentSize.height));
 [wSelf.cv scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:50 inSection:0] atScrollPosition:UICollectionViewScrollPositionBottom animated:YES];
 });
