动画UITableView调整大小

Question

Im using the following code to animate the resizing of a UITableView to make way for a UIView with extra controls when the UITableView.isEditing.

[UIView animateWithDuration:3 // 0.2 but slowed down to easily see difference
                      delay:0
                    options:UIViewAnimationOptionCurveEaseOut 
                 animations:^{
                     [self.selectControlsView setFrame:CGRectMake(0, self.tableView.frame.size.height-self.selectControlsView.frame.size.height, self.selectControlsView.frame.size.width, self.selectControlsView.frame.size.height)];
                     [self.tableView setFrame:CGRectMake(0, 0, self.tableView.frame.size.width, self.tableView.frame.size.height-self.selectControlsView.frame.size.height)];
                 }
                 completion:nil];

This works fine except it seems the UITableView animates faster than the UIView does (even though I adjust the UIViews frame before the UITableViews frame), causing a black flicker during the animation from the background.

Is there a way to animate the two views in tandem?

Answer 1

The problem was caused because the controller was a subclass of UITableViewController. I'm now subclassing UIViewController and adding the UITableView as a subview, the animation for adding the new view and resizing the UITableView now works as expected.
