Question

我的应用程序在iOS6中运行很酷，但是当我使用与我一起使用的相同代码更新iOS7时，当我尝试删除表中的行时出现此错误：

UIViewAnimation initWithView:indexPath:endRect:endAlpha:startFraction:endFraction:curve:animateFromCurrentPosition:shouldDeleteAfterAnimation:editing:

以下代码

- (void)tableView:(UITableView *)sender commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source.

        [self.tableView beginUpdates];
        PACallLog *aLog = _logs[indexPath.row];
        [[PAFMDBManager sharedManager] deleteACallLog:aLog];
        [_logs removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
        [self.tableView endUpdates];

    }
}

在viewDidAppear方法中，logs（array）从db获取值，所以当我删除行时，我应该 1.删除db中的数据 2.从日志中提取对象 3.执行deleteRowsAtIndexPaths方法

但有时我删除行时会崩溃（仅限于IOS7）有人可以帮助我吗？

Answer 1

删除行后，您可以再次重新加载tableview。在代码中添加此语句。 [tableview reloaddata];

Answer 2

- (void)tableView:(UITableView *)sender commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source.

        [self.tableView beginUpdates];
        PACallLog *aLog = _logs[indexPath.row];
        [[PAFMDBManager sharedManager] deleteACallLog:aLog];
        [_logs removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
        [self.tableView endUpdates];

        // Refill your array and table reload

    }
}

Answer 3

IT＆＃34;工作在您的commitEditingStyle方法的末尾添加此行，这将有助于您解决。

[TableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

崩溃有时在UITableView上删除行（仅在iOS7中）
