本文实例为大家分享了iOS实现相册多选图片上传的具体代码，供大家参考，具体内容如下

原理：获取手机里的全部照片，显示在自定义的视图里

//获取到相册的所有图片
- (void)addAllPhotos{
  @WeakObj(self);
  _assetsLibrary=[[ALAssetsLibrary alloc]init];
  [_assetsLibrary enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
    @StrongObj(self);
    if (group) {
      [group enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop) {
        if (result) {
          // 把相册储存到数组中，方便后面展示相册时使用
          CGImageRef cgImage = [result thumbnail];
          UIImage *image = [UIImage imageWithCGImage:cgImage];
          NSData *imageData = UIImageJPEGRepresentation(image,0.5);
          UIImage *newImage = [UIImage imageWithData:imageData];
          UZGPhotoChooseModel *model=[[UZGPhotoChooseModel alloc]init];
          model.image=newImage;
          model.currentImageIsSelect=NO;//初始化默认未选中
          model.showBackView=NO;//是否显示背景遮罩
          model.row=index;
          [self.cellInfoArray addObject:model];
          [self.myCollectionView reloadData];
        }
      }];
    }
  } failureBlock:^(NSError *error) {
    
  }];
}
//选中图片后刷新图片上面的选中数字
- (selectCellBolck)reloadCellSelectBlock:(NSIndexPath *)indexPath{
  @WeakObj(self);
  __block UZGPhotoChooseModel *model=self.cellInfoArray[indexPath.row];
  selectCellBolck block=^(BOOL current_isSelect){
    if (selfWeak.selectNum>self.max_selectNum) {
      return;
    }
    if (current_isSelect) {
      selfWeak.selectNum++;
    }else{
      selfWeak.selectNum--;
    }
    model.currentImageIsSelect=current_isSelect;
    model.totalNum=selfWeak.selectNum;
    [selfWeak.cellInfoArray replaceObjectAtIndex:indexPath.row withObject:model];
    [selfWeak reloadCurrentNum];
    [selfWeak.myCollectionView reloadData];
  };
  return block;
}
