实现预览并选中的需求时产生bug

[Lishuo15266176690]

TZImagePickerController *imagePickerVc = [[TZImagePickerController alloc] initWithMaxImagesCount:1 columnNumber:4 delegate:weakSelf pushPhotoPickerVc:NO];

设置的单选

TZImagePreviewController *previewVc = [[TZImagePreviewController alloc] initWithPhotos:videos currentIndex:idx tzImagePickerVc:imagePickerVc];

但传入数组用于展示后，选中的逻辑变为多选了
