我选择时会删除tableview中的单元格。每个单元格代表它自己的部分，所以我将它们删除如下
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.myData removeObjectAtIndex:indexPath.section];
[self.tableView beginUpdates];
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tableView endUpdates];
}
但有时 - 并非总是 - 我收到此错误
*** Assertion failure in -[UIViewAnimation initWithView:indexPath:endRect:endAlpha:startFraction:endFraction:curve:animateFromCurrentPosition:shouldDeleteAfterAnimation:editing:], /SourceCache/UIKit/UIKit-2903.23/UITableViewSupport.m:2661
不明白原因......
这是tableview及其图层
