//某行已经被选中时调用

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

{

            NSLog(@"非编辑状态下的选中");

            [tableView deselectRowAtIndexPath:indexPath animated:YES];

            DownLoadingTableViewCell * cell = (DownLoadingTableViewCell *) [downLoadingTableView cellForRowAtIndexPath:indexPath];

            //先将未到时间执行前的任务取消。

            [[self class] cancelPreviousPerformRequestsWithTarget:self selector:@selector(OnClickStartDownload:) object:cell.downLoadBtn];

            [self performSelector:@selector(OnClickStartDownload:)withObject:cell.downLoadBtn afterDelay:0.2f];

}

-(void)OnClickStartDownload:(id)sender

{

    //处理cell上按钮事件

}

同样这种处理方式用到button连续快速点击上

- (void) allPuseButtonClick//点击按钮触发事件

{

    //先将未到时间执行前的任务取消

    [[self class] cancelPreviousPerformRequestsWithTarget:self selector:@selector(allTaskBeginDownload)object:nil];

    [self performSelector:@selector(allTaskBeginDownload)withObject:nil afterDelay:0.2f];

}

- (void) allTaskBeginDownload

{

    //点击按钮触发事件后做的动作

}
