问题描述
我有一个UITableView，其中显示了启用了UITableViewCellAccessoryCheckmark选项的UITableView单元格。我想让用户选择自己喜欢的多个单元格，并在完成后按完成按钮。
I have a UITableView that shows UITableView cells with the UITableViewCellAccessoryCheckmark option enabled. I would like to let the user select multiple cells to their liking and when their done, press a "Done" button.
但是，当按下完成按钮时，我只需要将UITableView数组中的选定对象添加到一个单独的数组中即可。
However, when the "Done" button is pressed, I need to be able to add ONLY the selected object from the UITableView array into a separate array.
cell.accessoryType = UITableViewCellAccessoryCheckmark;
回顾一下：用户可以根据需要选择任意数量的单元格。完成后，他们按下UIButton，然后仅将选定的单元格添加到另一个数组。
To recap: User can select as many cells as they want. When done, they press a UIButton which then adds ONLY the selected cells to another array.
谢谢您的帮助！
更新：
-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self.setupTable cellForRowAtIndexPath:indexPath];
[self.selectedCells removeObject:[self.setupFeeds objectAtIndex:indexPath.row]];
cell.accessoryType = UITableViewCellAccessoryNone;
[self.setupTable deselectRowAtIndexPath:indexPath animated:YES];
}
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self.setupTable cellForRowAtIndexPath:indexPath];
[self.selectedCells addObject:[self.setupFeeds objectAtIndex:indexPath.row]];
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
推荐答案
您的问题与 UITableViewCellAccessory 或 UITableView 无关，因此标题有些误导。
Your question does not relate to UITableViewCellAccessory or UITableView so the title is somewhat misleading.
如果我是我，我会保存所选单元格的 NSMutableArray 作为实例变量或属性。
If I were you I would hold an NSMutableArray of selected cells as an instance variable or property.
@property (nonatomic, strong) NSMutableArray *selectedCells;
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Maybe some validation here (such as duplicates etc)
...
[self.selectedCells addObject:indexPath];
}
然后在按下完成后，您可以检查此属性以
And then when done is pressed you may check this property to see which cells are selected.
更新：
//Retrieve cell
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
//UITableViewCell has a textLabel property replace "yourLabel" with that if you have used it. Otherwise you can identify the label by subclassing tableviewcell or using tags.
[self.selectedCells addObject:cell.yourLabel.text];
//Then if cell is reselected
[self.selectedCells removeObject:cell.yourLabel.text];
