The .children property on Firebase iOS shows up as nil when there are child nodes

由 一曲冷凌霜 提交于 2019-12-11 12:06:04
问题 I asked this question a few days ago about retrieving data from Firebase. The answer to the question included a for-loop through child nodes using FEventTypeValue and the .children property on snapshots. It worked perfectly, doing what I needed it to do. However, I've tried using similar logic, and it shows the .children as nil. Here's what the data looks like: --languagesList ----English -------Ari ---------Age: 28 ---------Country: United States ---------distance: 2 -------Philip --------

Populating a UITableView in Firebase a Set Number of Cells at a time

由 心已入冬 提交于 2019-12-11 00:09:58

What is the point of salt and hashing if database is accessible?

由 心不动则不痛 提交于 2019-12-06 21:56:58
问题 I just learned the concept of hashing ("Hey! don't forget the salt!") and using salt to make the password secured. Hashing it is a one way encryption (actually not encryption but hashing) so it cannot be reversed engineered. Salting is prefixing or appending randomly created values to the password before hashing 'coz the problem in hashing (just hashing) is, some genius has provided a hash table of words from the dictionary so that they'll just compare the hash from that dictionary to the
