kandi X-RAY | gasper Summary
Back-up & encrypt your files in a distributed manner, across multiple stores of your choice, by splitting them to shares. Retrieve them at any point, with only a minimum number of shares required for retrieval. Each file is being split to multiple shares, all of which are distributed to different destinations defined by you (be it AWS S3, Dropbox, Google Drive, your local filesystem, FTP Server, etc...). You can retrieve your file at any given moment, even if you only have access to a part of the stores you originally used (down to a minimium threshold of your choice). Gasper is based on the awesome Shamir's Secret Sharing algorithm. Source: Robin's Snippet blog.

QUESTION
I have a FlatList where I'm trying to scroll through each index of my data array every X amount of seconds. There's only two items in my array right now but there could be more. The current code works for the first two iterations but then it does not seem to reset properly and I get the scrollToIndex out of range error: index is 2 but maximum is 1. I would think that when the currentIndex is >= data.length my if statement would setCurrentIndex back to 0 but it doesn't seem to work. Basically what I'm trying to do is loop the items in the Flatlist automatically but each item pausing for a few seconds.
ANSWER
Answered 2021-Jan-26 at 14:58looks like your if statement is incorrect, the maximum index should be totalLength - 1.
for example, we have an array of 3 items: [{id: 1, index: 0}, {id: 2, index: 1}, {id: 3, index: 2}], then the length of the array is 3, but the maximum index is 2, so when the current index is ">= 2 (totalLength - 1)", you should reset it to 0. and for the else conditions, set next index to 'currentIdx + 1'
QUESTION
I have the following setup: a UICollectionView with a custom cell, where the user can select multiple cells and then perform some heavy image operation. Now I try to update the selected cells which the user selected with the result of that operation, which will be produced by a function of the subclassed custom cell. For all visible cells, the function is called on button press by the user and for all other cells, this happens via cellForItemAt in order to be most efficient.
However, I face the problem now, that the visible cells are all updated but then after scrolling the cells right behind or before the visible cells do not get updated via cellForItemAt but only when scrolling forth and back. Please see the attached video.
For demonstration purposes I just show a green UIView for the image operation. Because that operation is resource heavy, I cannot use any of the UICollectionView reloadData or similar, as they would deselect the selected cells, and manual re-selection will cause flickering.

...ANSWER
Answered 2020-Mar-02 at 20:40UICollectionView defaults to prefetchingEnabled == YES, which means that the collection view will request cells before it needs to display them. If the app's state changes such that the cells that have already been fetched need to be displayed differently, you can implement the collectionView:willDisplayCell:forItemAtIndexPath: method to update the cell.
It looks like this is exactly your problem... you turn on a feature that should change the way the cells look, but the cells that have been fetched but which aren't visible don't get updated. Implementing collectionView:willDisplayCell:forItemAtIndexPath: should solve the problem.
