我已经尝试了一切来实现这一点,但是当我滚动cellForRowAtIndexPath
时,它似乎是在我的tableview上添加和删除复选标记,有人可以帮忙吗?
// Configure the cell...
cell.textLabel.text = [currencyList objectAtIndex:indexPath.row];
// Check to see what currency is currently selected and checkstyle
if ([selectedCurrency isEqualToString:cell.textLabel.text]) {
// Add a tick to the selected row
cell.accessoryType = UITableViewCellAccessoryCheckmark;
// Change the text colour
cell.textLabel.textColor = [UIColor colorWithRed:0 green:0 blue:0.5 alpha:1];
self.checkedIndexPath = indexPath;
} else {
UITableViewCell *uncheckCell = [self.tableView
cellForRowAtIndexPath:self.checkedIndexPath];
uncheckCell.accessoryType = UITableViewCellAccessoryNone;
// Change the font colour back to black
uncheckCell.textLabel.textColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
}
答案 0 :(得分:1)
您无需取消选中cellForRowAtIndexPath
中的单元格。更好的溶解只是重新加载检查细胞。
- (void)setCheckedIndexPath:(NSIndexPath *)indexPath
{
NSIndexPath *uncheckIndexPath = self.checkedIndexPath;
_checkedIndexPath = indexPath;
[self.tableView reloadRowsAtIndexPaths:@[uncheckIndexPath]
withRowAnimation:UITableViewRowAnimationLeft];
}
并更改cellForRowAtIndexPath
。请注意,我们将UITableViewCellAccessoryNone
设置为我们必须返回的单元格,而不是您要取消选中的单元格。
// Configure the cell...
cell.textLabel.text = [currencyList objectAtIndex:indexPath.row];
// Check to see what currency is currently selected and checkstyle
if ([selectedCurrency isEqualToString:cell.textLabel.text]) {
// Add a tick to the selected row
cell.accessoryType = UITableViewCellAccessoryCheckmark;
// Change the text colour
cell.textLabel.textColor = [UIColor colorWithRed:0 green:0 blue:0.5 alpha:1];
self.checkedIndexPath = indexPath;
} else {
//If cell unchecked
cell.accessoryType = UITableViewCellAccessoryNone;
// Change the font colour back to black
cell.textLabel.textColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
}
