Question

想要在单元格上用vinger轻扫时删除一行。

我明白了：

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

    NSLog(@"Delete");

}

运行删除按钮后出现，但是当我按下它时没有任何反应。我需要在括号中插入什么内容？

我的.m

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

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSString *str = cell.textLabel.text;

    NSLog(@"U selected %@", str);
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

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

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [self.dataSourceArray removeObjectAtIndex:indexPath.row];//or something similar to this based on your data source array structure
        //remove the corresponding object from your data source array before this or else you will get a crash
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.array = @[@"test",@"test"];

    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    [refreshControl addTarget:nil action:@selector(updateArray) forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;

}

试试这个，

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

  if (editingStyle == UITableViewCellEditingStyleDelete) {
     [self.array removeObjectAtIndex:indexPath.row];//or something similar to this based on your data source array structure
//remove the corresponding object from your data source array before this or else you will get a crash
     [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 
  }
}
