ios-tableviewcell中的觸發事件，為什麼當我離開這一行才觸發呢？

tableviewcell中的觸發事件，為什麼當我離開這一行才觸發呢？

下面是我的代碼

-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];

//indexPath.row得到選中的行號。
NSLog(@"%ld",(long)indexPath.row);
switch (indexPath.row) {
    case 0:
    {   //初始化界面
        HLNoAudit *my = [[HLNoAudit alloc] init];
          my.title =[self.list objectAtIndex:0];
        //設置返回鍵
        UIButton *back = [UIButton buttonWithType:UIButtonTypeCustom];
        back.frame = CGRectMake(0, 0, 30, 30);
        [back setBackgroundImage:[UIImage imageNamed:@"arrow_left"] forState:UIControlStateNormal  ];
        [back setTitleColor:[UIColor redColor]forState:UIControlStateNormal];
        [back addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
        my.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:back];
        [self.navigationController pushViewController:my animated:YES];
    }
        break;
    case 1:
    {
        HLAlreadyAudit *my = [[HLAlreadyAudit alloc] init];
        my.title =[self.list objectAtIndex:1];
        //設置返回鍵
        UIButton *back = [UIButton buttonWithType:UIButtonTypeCustom];
        back.frame = CGRectMake(0, 0, 30, 30);
        [back setBackgroundImage:[UIImage imageNamed:@"arrow_left"] forState:UIControlStateNormal  ];
        [back setTitleColor:[UIColor redColor]forState:UIControlStateNormal];
        [back addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
        my.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:back];
        [self.navigationController pushViewController:my animated:YES];

最佳回答：

你選用的方法是錯誤的， 應該用didSelectRowAtIndexPath而不是 didDeselectRowAtIndexPath。使用didDeselectRowAtIndexPath方法第一次點擊選中cell是沒有反應的，當點擊其他的cell之後才取消之前選中的cell，然後才能調用didSelectRowAtIndexPath方法。
