主要是在模型里面设一个属性isSelected
@protocol DBButtonDelegate <NSObject>
- (void)didSelectedButton:(UITableViewCell *)cell;
@end
- (void)mainBtnClick {
[self.delegate didSelectedButton:self];
}
- (void)didSelectedButton:(UITableViewCell *)cell {
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
NSInteger index = indexPath.row;
self.mainID = index;
for (NSInteger i = 0; i < _viewModel.products.count; i++) {
DBProduct *product = _viewModel.products[i];
if (i == index) {
product.isSelected = YES;
} else {
product.isSelected = NO;
}
}
[self.tableView reloadData];
}
