如何在 UITableView 单元格上嵌入 UISwitch？示例可以在设置菜单中看到。

我目前的解决方案:

UISwitch *mySwitch = [[[UISwitch alloc] init] autorelease];
cell.accessoryView = mySwitch;

最佳答案

将其设置为附件 View 通常是要走的路。您可以在 tableView:cellForRowAtIndexPath: 中设置它。您可能希望在切换开关时使用目标/ Action 来执行某些操作。像这样:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    switch( [indexPath row] ) {
        case MY_SWITCH_CELL: {
            UITableViewCell *aCell = [tableView dequeueReusableCellWithIdentifier:@"SwitchCell"];
            if( aCell == nil ) {
                aCell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"SwitchCell"] autorelease];
                aCell.textLabel.text = @"I Have A Switch";
                aCell.selectionStyle = UITableViewCellSelectionStyleNone;
                UISwitch *switchView = [[UISwitch alloc] initWithFrame:CGRectZero];
                aCell.accessoryView = switchView;
                [switchView setOn:NO animated:NO];
                [switchView addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
                [switchView release];
            }
            return aCell;
        }
        break;
    }
    return nil;
}

- (void)switchChanged:(id)sender {
    UISwitch *switchControl = sender;
    NSLog( @"The switch is %@", switchControl.on ? @"ON" : @"OFF" );
}
