Question

当用户点击一个单元格时，我正在为表视图设置动画。虽然我第一次点击单元格时会调用我的DidSeclectRowAtIndexPath，但动画不会发生。在第二次点击时，动画块被触发。可能导致此问题的原因是什么？

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    self.ChosenSubCategory=[self.SubCategoryListArray objectAtIndex:indexPath.row];
    [self getUserSpecificLevelDetails];
   // [self ShowLevelPickerView];

    [UIView animateWithDuration:1.0 animations:^{
             [self.ChooseLevelView setCenter:CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2)];
        [player prepareToPlay];
        [player play];
    }];


}

可能是因为线程问题。

请尝试以下解决方案。希望它有效。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath 

*)indexPath
{
    self.ChosenSubCategory=[self.SubCategoryListArray objectAtIndex:indexPath.row];
    [self getUserSpecificLevelDetails];
   // [self ShowLevelPickerView];

    [self performSelector:@selector(performOperation) withObject:nil afterDelay:0];
}


- (void)performOperation
{
      [UIView animateWithDuration:1.0 animations:^{
             [self.ChooseLevelView setCenter:CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2)];
        [player prepareToPlay];
        [player play];
    }];`
}

在第一次点击时无法从didselectrowatindexpath开始动画？
