删除单元格并重新加载表视图时访问错误 [英] Getting bad access while deleting cell and reloading table view

问题描述

我正在尝试使用自定义UITableViewCell构建一个表，但在删除单元格后，当我尝试加载视图时，我收到一个EXC_BAD_ACCESS错误，这里我从字典中获取数据并将其加载到表视图。

I am trying to build a table using custom UITableViewCell, but after deleting cell and when I try load the view, I get an EXC_BAD_ACCESS error,here i'm getting data from a dictionary and loading it to table view.

我的表格代码如下：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    cell = (uploadCustomCell *)[tabelView1 dequeueReusableCellWithIdentifier:@"cell"];
    [cell setSelectionStyle:UITableViewCellEditingStyleNone];
    if (cell == nil) {
        [[NSBundle mainBundle]loadNibNamed:@"uploadCustomCell" owner:self options:nil];
        cell = (uploadCustomCell  *)self.uploadCustomcell;
    }
    saveBtnCcell.hidden = YES;
    cell.textNamefield.hidden = YES;
    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
    [cell.defaultSwitch setEnabled:NO];
    NSMutableArray *dictionary = [contents objectAtIndex:indexPath.row];
    NSLog(@"dict dict :%@",dictionary);
//
    cell.nameLabelCell.text   = [dictionary valueForKey:@"VideoName"];
    cell.userName.text = [dictionary valueForKey:@"User"];
    NSString *defaultVideo = [dictionary valueForKey:@"DefaultVideo"];

    if ([defaultVideo isEqualToString:@"1"]) {
        [cell.defaultSwitch setOn:YES animated:YES];
    }
    else {
        [cell.defaultSwitch setOn:NO animated:YES];
    }

    [cell.defaultSwitch addTarget:self action:@selector(setState:) forControlEvents:UIControlEventValueChanged];
    cell.thumbImg.image = [arrayimage objectAtIndex:indexPath.row];
    VideoNameTextField.hidden = YES;
    return cell;
}

- (void)setState:(id)sender {
    state = [sender isOn];
   //    NSString *rez = state == YES ? @"YES" : @"NO";
   NSLog(@"state.........:%d",state);
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath     *)indexPath {
    NSLog(@"height:%f",uploadCustomcell.frame.size.height);
    return 207;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSMutableArray *dictionary = [contents objectAtIndex:indexPath.row];
    NSLog(@"Dictionary:%@",dictionary);
    NSLog(@"indexpath:%@",indexPath);
    //
    NSLog(@"at index%d obj:%@",indexPath.row,dictionary);
    NSString *nameDetails = [dictionary valueForKey:@"VideoName"];

    guid = [dictionary valueForKey:@"GUID"];

    detailsNameLbl.text = nameDetails;
    detailsVehImg.image = [arrayimage objectAtIndex:indexPath.row];;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:
       (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {  
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [contents removeObjectAtIndex:indexPath.row];
        [tabelView1 reloadData];
    }
}

推荐答案

尝试这个：
[tableView deleteRowsAtIndexPaths：[NSArray arrayWithObject：indexPath] withRowAnimation：UITableViewRowAnimationFade];

您还必须使用此方法：

You must use this method also:

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { 
   return UITableViewCellEditingStyleDelete; 
} 



- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[contents removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
//[tabelView1 reloadData];

}
