uitableview 重新排序不起作用，源始终等于目标 [英] uitableview re-order won't work, source always equal to destination

问题描述

我有一个不会重新排序的tableview.看起来 moveRowAtIndexPath 从未使用与 destinationIndexPath 不同的 sourceIndexPath 调用.当我拉一排时，它会弹回到起始位置，就好像该排不支持移动一样.

I have a tableview that won't reorder. It looks like moveRowAtIndexPath is never called with a sourceIndexPath that is different from the destinationIndexPath. When I pull a row, it bounces back to its starting location as if the row didn't support movement.

我尝试实现所有canMove/canEdit/propose"方法以返回 YES，但我观察到相同的行为.怎么回事?

I tried implementing all the "canMove/canEdit/propose" methods to return YES, but I observe the same behavior. What's going on?

- (void) tableView:(UITableView *)tableView
moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath
       toIndexPath:(NSIndexPath *)destinationIndexPath {

    NSLog(@"%d -> %d", [sourceIndexPath row], [destinationIndexPath row]);
    if ([sourceIndexPath row] == [destinationIndexPath row]) {
        return;
    }

    MyDomain *domain = [self getObject];
    [domain.stuff exchangeObjectAtIndex:(NSUInteger) [sourceIndexPath row] withObjectAtIndex:(NSUInteger) [destinationIndexPath row]];
}

推荐答案

我正在使用 IIViewDeckController，它取消了视图中的平移.

I'm using IIViewDeckController, which cancels panning in views.

设置 ViewDeckController 时，请执行以下操作:self.panningCancelsTouchesInView = NO;

When setting up the ViewDeckController, do this: self.panningCancelsTouchesInView = NO;
