報(bào)錯(cuò)

報(bào)錯(cuò)堆棧

報(bào)錯(cuò)原因：在子線程中做了操作UI的操作

問題代碼：

 
@weakify(self);
  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
      @strongify(self);
      // 獲得全部相片
      PHFetchResult<PHAssetCollection *> *cameraCollections = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeSmartAlbumUserLibrary options:nil];
      // 獲得個(gè)人收藏相冊(cè)
      PHFetchResult<PHAssetCollection *> *favoritesCollections = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeSmartAlbumFavorites options:nil];
      // 獲得相機(jī)膠卷
      PHFetchResult<PHAssetCollection *> *assetCollections = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeSmartAlbumUserLibrary options:nil];
  });

原因：iOS13之后PHCollection獲取相冊(cè)只能在主線程中進(jìn)行

代碼修改之后：
