对TZImagePickerController进行封装的工具T

前言：TZImagePickerController 是非常优秀的获取系统图片的第三方库，为了方便调用，本人封装了一个工具TZImagePickerHelper。

1. 控制器中初始化一个helper

_helper = [[TZImagePickerHelper alloc] init];

2. 调用helper中方法 showImagePickerControllerWithMaxCount

[self.helper showImagePickerControllerWithMaxCount:(MAX_COUNT - self.imagesURL.count) WithViewController:self];

3. block回调数据，刷新界面显示

    WeakPointer(weakSelf);
    _helper.finish = ^(NSArray *array){
        [weakSelf.imagesURL addObjectsFromArray:array];
        weakSelf.layout.itemCount = weakSelf.imagesURL.count;
        dispatch_async(dispatch_get_main_queue(), ^{
            [weakSelf.collectionView reloadData];
        });
    };
