}
这是我的代码,当我开始向下或向上滚动表格时,我检查过的第一个单元格已经松开了复选标记符号,它只是隐藏了一下..我的代码出了什么问题?

重用Cell,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
int getIndex = [sharedGameState.selectedValues indexOfObject:[NSNumber numberWithInt:indexPath.row]];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
if(getIndex<21)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
} // END HERE
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}

选择多行:
- (void)addTableView {
self.tableView = [[UITableView alloc] initWithFrame:CGRectMake("whatever frame you want to set")
style:UITableViewStylePlain];
self.tableView.dataSource = self;
self.tableView.delegate = self;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.timeSheetEntryTableView.allowsMultipleSelection = YES;
self.array = [[NSMutableArray alloc]init];
[self.view addSubview:self.tableView];
}
//索引路径的行的单元格
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdentifier = @"Cell Identifier";
self.cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!self.cell) {
self.cell = [[Cell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:cellIdentifier];
self.cell.accessoryType = UITableViewCellAccessoryNone;
}
self.cell.selectionStyle = UITableViewCellSelectionStyleNone;
if ([self.array containsObject:indexPath])
{
[self.cell.checkImage setImage:[UIImage imageNamed:@"check_box_selected.png"]];
}
else
{
[self.cell.checkImage setImage:[UIImage imageNamed:@"check_box.png"]];
}
return self.cell;
}
//确实选择并取消选择 //我使用了自定义单元格
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.cell = [tableView cellForRowAtIndexPath:indexPath];
[self.array addObject:indexPath];
[self.cell.checkImage setImage:[UIImage imageNamed:@"check_box_selected.png"]];
}
- (void)tableView:(UITableView *)tableView
didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
self.cell = [tableView cellForRowAtIndexPath:indexPath];
[self.array removeObject:indexPath];
[self.cell.checkImage setImage:[UIImage imageNamed:@"check_box.png"]];
}
