Сбой при прокрутке uitableview

Question

У меня есть uitableview, который вылетает при прокрутке.

Я пробовал утечки, собирал и анализировал, но не мог решить эту проблему.

получая ошибку ниже

*** -[CALayer retain]: message sent to deallocated instance 0xe192280

Ниже приведен код, который я запускаю.

Answer 1

Вы на самом деле не используете повторно какую-либо ячейку, потому что вы делаете все части внутри ячейки == nil code bloack, 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 падает ли он после замены кода на этот.

Answer 2

Во-первых, механизм повторного использования ячейки не работает в вашем коде, потому что вы делаете:

static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// ...
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];

Вы пытаетесь повторно использовать ячейку с идентификатором «Ячейка»?но когда вы создаете ячейку, вы создаете ее с помощью reuseIdentifier "MyIdentifier".Это плохо.Вы должны создать ячейку с тем же идентификатором:

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

и переместить свою часть для индивидуальной настройки ячейки (в зависимости от indexPath) вне оператора if (cell == nil) {.Внутри этого утверждения вы должны только глобальную настройку для ваших ячеек.Настройте здесь только одни и те же вещи для всех ячеек в этом представлении.Потому что эта ячейка будет использоваться повторно для других ячеек.

Когда мы используем механизм повторного использования для ячеек, он пытается найти ячейку с идентификатором (вызывая [tableView dequeueReusableCellWithIdentifier:CellIdentifier]).Если он не найден, то вы создаете прототип ячейки с тем же идентификатором

if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
}

и после этой части кода размещаете свой конкретный код для текущей ячейки (по указанному indexPath)

Answer 3

Где вы отпускаете все объекты, которые вы выделяете? Похоже, вы пытаетесь размещать одни и те же объекты снова и снова.

попробуйте следующий подход:

UILabel  *lblTitle = [[[UILabel alloc] initWithFrame: cellRect1] autorelease];
