Вопрос:
У меня есть uitableview, который вылетает при прокрутке.
Я пробовал утечки, сборку и анализ, но не смог решить эту проблему.
получение приведенной ниже ошибки

Комментарии:
1. Не было бы НАМНОГО проще для вас и меньше кодирования, если бы вы сохранили свои значения в массиве / объекте? А может быть, подкласс UITableViewCell?
Ответ №1:
На самом деле вы не используете повторно ни одну ячейку, потому что вы выполняете всю часть внутри ячейки == ошибка кода nil, изменяя код примерно так
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UIFont *font = [UIFont fontWithName:@"Arial" size:13];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
UILabel* lblColon = [[UILabel alloc] initWithFrame:CGRectMake(135, 10, 5, 20 )];
lblColon.font = font;
lblColon.backgroundColor = [UIColor clearColor];
lblColon.textColor = [UIColor blackColor];
lblColon.text = @":";
[lblColon setTag:222];
[cell.contentView addSubview: lblColon];
[lblColon release];
}
NSInteger row = [indexPath row];
UILabel* lblToReuse = (UILabel*)[cell.contentView viewWithTag:222];
if (tableView == tblCompanyDetails) {
//usual things you were doing earlier
}
return cell;
}
может вам немного помочь. Проверьте, не происходит ли сбой после замены кода на этот.
Ответ №2:
Где вы освобождаете все объекты, которые вы выделяете? Похоже, вы пытаетесь распределять одни и те же объекты снова и снова.
попробуйте следующий подход:
UILabel *lblTitle = [[[UILabel alloc] initWithFrame: cellRect1] autorelease];
Ответ №3:
Во-первых, механизм повторного использования ячейки не работает в вашем коде, потому что вы:
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// ...
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
Вы пытаетесь повторно использовать ячейку с идентификатором «Cell»? но когда вы создаете ячейку, вы создаете ее с помощью повторного идентификатора «MyIdentifier». Это плохо. Вы должны создать ячейку с тем же идентификатором:
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
И переместите свою часть для индивидуальной настройки ячейки (в зависимости от indexPath) вне if (cell == nil) { инструкции. Внутри этого оператора вы должны выполнять только глобальную настройку для своих ячеек. Настройте здесь только те же вещи для всех ячеек в этом представлении tanle. Потому что эта ячейка будет повторно использована для других ячеек.
Когда мы используем механизм повторного использования для ячеек, он пытается найти ячейку с идентификатором (вызывающий [tableView dequeueReusableCellWithIdentifier:CellIdentifier] ). Если он не найден, вы создаете прототип ячейки с тем же идентификатором
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
}
и после этой части кода поместите свой конкретный код для текущей ячейки (в указанном indexPath)
