I do not want animation in the begin updates, end updates block for uitableview?

Question

I have a UITableView that is using a custom table cell and each cell has a UIWebView.

Because UIWebView took along time to load, i want to avoid reloading them at al

Answer 1

One more way to do it using blocks

Obj-C

[UIView performWithoutAnimation:^{
   [self.tableView beginUpdates];
   [self.tableView endUpdates];
}];

Swift

UIView.performWithoutAnimation {
    tableView.beginUpdates()
    tableView.endUpdates()   
}

Answer 2

Swifties I had to do the following for this to work:

// Sadly, this is not as simple as calling:
//      UIView.setAnimationsEnabled(false)
//      self.tableView.beginUpdates()
//      self.tableView.endUpdates()
//      UIView.setAnimationsEnabled(true)

// We need to disable the animations.
UIView.setAnimationsEnabled(false)
CATransaction.begin()

// And we also need to set the completion block,
CATransaction.setCompletionBlock { () -> Void in
    // of the animation.
    UIView.setAnimationsEnabled(true)
}

// Call the stuff we need to.
self.tableView.beginUpdates()
self.tableView.endUpdates()

// Commit the animation.
CATransaction.commit()

Answer 3

[UIView setAnimationsEnabled:NO];
[tableView beginUpdates];
[tableView endUpdates];
[UIView setAnimationsEnabled:YES];

Answer 4

I prefer to have a smooth transition:

CGPoint offset = self.tableView.contentOffset;
[UIView transitionWithView:self.tableView duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
        [self.tableView reloadData];
        self.tableView.contentOffset = offset;
    } completion:nil];

give it a try.

Answer 5

I wanted to updated the cell height for section 5 and following code worked for me:

UiView.setAnimationsEnabled(False)
self.productTableView.reloadSections(NSIndexSet(index: SectionType.ProductDescription.hashValue), withRowAnimation: UITableViewRowAnimation.None)
self.productTableView.scrollToRowAtIndexPath(NSIndexPath(forRow: 0, inSection: 5), atScrollPosition: UITableViewScrollPosition.Bottom, animated: false)
UIView.setAnimationsEnabled(true)

Answer 6

working on my project, but not a common solution.

let loc = tableView.contentOffset
UIView.performWithoutAnimation {

    tableView.reloadData()

    tableView.layoutIfNeeded()
    tableView.beginUpdates()
    tableView.endUpdates()

    tableView.layer.removeAllAnimations()
}
tableView.setContentOffset(loc, animated: true)//animation true may perform better
