UITableview 多选 解决cell重用问题

原文地址：http://blog.csdn.net/u011254628/article/details/18089503

假如  我们有100个cell  这时肯定 是需要重用的

解决方案 在  didselesctCell  中记录所选择的   indexPath 

[objc] view plaincopy

1. PERenewalGetViewCell * selectCell = (PERenewalGetViewCell*)[tableView cellForRowAtIndexPath:indexPath];  
2. [tableView deselectRowAtIndexPath:indexPath animated:YES];  
3.   
4.   
5. if (_selectIndexArray.count == 0) {  
6.     [_selectIndexArray addObject:indexPath];  
7. }else{  
8.     for (int a = 0 ; a < _selectIndexArray.count ; a++) {  
9.         //deleteElemnet = YES;  
10.         if ([_selectIndexArray[a] isEqual:indexPath]) {  
11.             [_selectIndexArray removeObject:indexPath];  
12.             deleteElemnet = NO;  
13.             [selectCell.selectButton setBackgroundImage:[UIImage imageNamed:@"mobilePhoneValidate_frame_n"] forState:UIControlStateNormal];  
14.         }  
15.     }  
16.       
17.     if (deleteElemnet == YES) {  
18.         [_selectIndexArray addObject:indexPath];  
19.         deleteElemnet = NO;  
20.         [selectCell.selectButton setBackgroundImage:[UIImage imageNamed:@"mobilePhoneValidate_frame_s"] forState:UIControlStateNormal];  
21.   
22.     }  
23. }  
24. deleteElemnet = YES;  

在

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

 中

#pragma mark - 是否勾选对号 解决重用问题

    if([_selectIndexArraycontainsObject:indexPath]){

        cell.accessoryType=UITableViewCellAccessoryCheckmark;

        [cell.selectButtonsetBackgroundImage:[UIImageimageNamed:@"mobilePhoneValidate_frame_s"]forState:UIControlStateNormal];

    }else{

        cell.accessoryType=UITableViewCellAccessoryNone;

        [cell.selectButtonsetBackgroundImage:[UIImageimageNamed:@"mobilePhoneValidate_frame_n"]forState:UIControlStateNormal];

    }
