当我在 tableview 的搜索栏中搜索时如何检索复选框按钮位置更改

Question

for(int i=0; i<[devices count]; i++) { 
    [_cellDataArray addObject:@"Uncheck"];
}

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {

Answer 1

In table view you retuned two arrays based on searching. Instead of that take two arrays one for main and second one is tempArray and returned only tempArray in table View. First add all main array values into tempArray. Next if any Search is there then change the tempArray. Take it tempArray as NSMutableArray.

Next don't hold the indexPath rows for selection. Because it may change if array changed. So hold objectId's in selection. If you don't have any IDs to your objects. Then create your custom object and change your original objects to custom objects. In custom Object set id value.
