我正在从包含两个字符串和一个整数的实体更新 TableViewController。字符串正常工作整数没有。这是我的代码;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UsersCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[GolfersCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
Users *users = [_fetchedResultsController objectAtIndexPath:indexPath];
cell.firstName.text = users.firstName;
cell.lastName.text = users.lastName;
int i = [users.gendID intValue] ;
cell.genID.text = [NSString stringWithFormat:@"%d", i];
[self configureCell:cell atIndexPath:indexPath];
return cell;
}
现在这确实有效,注释掉“int i = [users.gendID intValue] ;”这一行 把它留在里面并单步执行程序,这是它返回的错误;
