具有2个动画的insertRowsAtIndexPaths

Question

I am currently inserting cells in my UITableView with the following code:

[rottenTableView insertRowsAtIndexPaths:indexPathsToInsert withRowAnimation:UITableViewRowAnimationTop];

It does the job correctly with the animation UITableViewRowAnimationTop . However, I would like to insert the cells with 2 animations at the same time ( UITableViewRowAnimationTop and UITableViewRowAnimationFade ). I tried the following:

[rottenTableView insertRowsAtIndexPaths:indexPathsToInsert withRowAnimation:(UITableViewRowAnimationTop|UITableViewRowAnimationFade)];

This code does not seem to animate insertion any differently than before. Any way to perform both animations?

Answer 1

As far as I know, when you use -insertRowsAtIndexPaths:withRowAnimation: there could be only one animation type for a single cell simultaneously. But I could suggest using different animation types for different cells at the same time. For this you can use batch UITableView cell's updation via using beginUpdates / endUpdates . All the animations will fire at the same time, you can use it like this:

[tableView beginUpdates];

[tableView insertRowsAtIndexPaths:insertIndexPaths1 withRowAnimation:UITableViewRowAnimationRight];
[tableView insertRowsAtIndexPaths:insertIndexPaths2 withRowAnimation:UITableViewRowAnimationOTHER];

[tableView endUpdates];
