iOS tableView编辑删除（单选 多选）

viewDidload 添加

for (int i = 0; i <_reouseArray.count ; i++) {NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];[dictionary setValue:@"NO" forKey:[NSString stringWithFormat:@"%d", i]];[_contacts addObject:dictionary];}

cellForRow中进行赋值

    NSMutableDictionary *dictionary = [_contacts objectAtIndex:[indexPath row]];    if ([[dictionary objectForKey:keyForChecked] isEqualToString:@"NO"]) {        [dictionary setObject:@"NO" forKey:keyForChecked];        [_showMediaCell setChecked:NO];            }else {        [dic_material setObject:@"YES" forKey:keyForChecked];        [_showMediaCell setChecked:YES];            }#define keyForChecked [NSString stringWithFormat:@"%ld", (long)indexPath.row]

<pre name="code" class="objc">didSelect方法获取单个点击／取消操作

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {        [collectionView deselectItemAtIndexPath:indexPath animated:YES];        NewShowCollectionViewCell *cell = (NewShowCollectionViewCell*)[collectionView cellForItemAtIndexPath:indexPath];    dic_material = [_contacts objectAtIndex:[indexPath row]];    if ([[dic_material objectForKey:keyForChecked] isEqualToString:@"NO"] ) {// && [_editState isEqualToString:@"on"]        [dic_material setObject:@"YES" forKey:keyForChecked];        [cell setChecked:YES];        id addObject = [_reouseArray objectAtIndex:[indexPath row]];        [self.removeList addObject:addObject];    }else{         [dic_material setObject:@"NO" forKey:keyForChecked];        [cell setChecked:NO];         id removeObject = [_reouseArray objectAtIndex:[indexPath row]];        [self.removeList removeObject:removeObject];            } }

// 全选操作- (void)editAllTheDeleteItems {            if (is_editAll) {                for (int i = 0; i < self.reouseArray.count; i ++) {                 NSIndexPath *indexPath = [NSIndexPath indexPathForItem:i inSection:0];                NewShowCollectionViewCell *cell = (NewShowCollectionViewCell*)[self.collectionView cellForItemAtIndexPath:indexPath];                NSUInteger row = [indexPath row];                NSMutableDictionary *dictionary = [_contacts objectAtIndex:row];                [dictionary setObject:@"YES" forKey:keyForChecked];                [cell setChecked:YES];                [self.removeList addObject:_reouseArray[i]];                is_editAll = NO;                [_editAllBtn setImage:[UIImage imageNamed:@"全选2"] forState:(UIControlStateNormal)];             }            }else{                for (int i = 0; i < self.reouseArray.count; i ++) {                                NSIndexPath *indexPath = [NSIndexPath indexPathForItem:i inSection:0];                NewShowCollectionViewCell *cell = (NewShowCollectionViewCell*)[self.collectionView cellForItemAtIndexPath:indexPath];                NSUInteger row = [indexPath row];                NSMutableDictionary *dictionary = [_contacts objectAtIndex:row];                [dictionary setObject:@"NO" forKey:keyForChecked];                [cell setChecked:NO];                [self.removeList removeObject:_reouseArray[i]];                is_editAll = YES;                [_editAllBtn setImage:[UIImage imageNamed:@"全选1"] forState:(UIControlStateNormal)];             }        }}

自定义cell中

<pre name="code" class="objc">- (void)setChecked:(BOOL)checked{    if (checked)    {        [_selectBtn setImage:[UIImage imageNamed:@"选择2"] forState:(UIControlStateNormal)];    }    else    {        [_selectBtn setImage:[UIImage imageNamed:@"选择1"] forState:(UIControlStateNormal)];    }    _checkedForSelect = checked;}
