UITableView 清单
我正在使用 UITableView 制作一个清单程序,并且我设法实现了直到选择并显示复选标记的所有内容。但是,当我滚动离开单元格时。复选标记消失。
我有以下代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CellIdentifier";
// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
if(tableView == Table1){
switch(indexPath.section){
case 0:
cell.textLabel.text =[array1 objectAtIndex:indexPath.row];
break;
case 1:
cell.textLabel.text = [array2 objectAtIndex:indexPath.row];
break;
case 2:
cell.textLabel.text = [array3 objectAtIndex:indexPath.row];
break;
}
//cell.textLabel.text = [NSString stringWithFormat:@"Row %d", indexPath.row];
}
//if([indexPath compare:[selectedArray objectAtIndex:i]] == NSOrderedSame){
if([selectedArray containsObject:cell]){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else{
cell.accessoryType = UITableViewCellAccessoryNone;
}
//}
if(tableView == sauceTable){
cell.textLabel.text = [array4 objectAtIndex:indexPath.row];
}
return cell;}
并且:
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *c= [aTableView cellForRowAtIndexPath: indexPath];
c.accessoryType = UITableViewCellAccessoryCheckmark;
[selectedArray addObject: c];
}
有什么想法吗?
I'm making a checklist program using UITableView and I managed to implement everything up to selection and making a checkmark appear. However, when I scroll away from the cells. The checkmark disappears.
I have the following code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CellIdentifier";
// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
if(tableView == Table1){
switch(indexPath.section){
case 0:
cell.textLabel.text =[array1 objectAtIndex:indexPath.row];
break;
case 1:
cell.textLabel.text = [array2 objectAtIndex:indexPath.row];
break;
case 2:
cell.textLabel.text = [array3 objectAtIndex:indexPath.row];
break;
}
//cell.textLabel.text = [NSString stringWithFormat:@"Row %d", indexPath.row];
}
//if([indexPath compare:[selectedArray objectAtIndex:i]] == NSOrderedSame){
if([selectedArray containsObject:cell]){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else{
cell.accessoryType = UITableViewCellAccessoryNone;
}
//}
if(tableView == sauceTable){
cell.textLabel.text = [array4 objectAtIndex:indexPath.row];
}
return cell;}
And:
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *c= [aTableView cellForRowAtIndexPath: indexPath];
c.accessoryType = UITableViewCellAccessoryCheckmark;
[selectedArray addObject: c];
}
Any ideas?

解决了。使用 NSIndexPath 而不是 UITableViewCell 作为选择数组
Solved. Used NSIndexPath instead of UITableViewCell for the selectionArray
