I spent some more time revisiting the Susan’s Charming Trinkets app.
Previously I was able to read from the cloud database. This weekend I was able to take that data that I received, and add it to a local data store. Furthermore, I am able to read from that datastore.
Next steps: Read from the local datastore and use the image data from there to populate the UICollectionView..
I previously had used a “Lazy” loader, but with this new approach I should be able to use standard code to populate the collection view.
I’ll try both ways and see which I like better. The disadvantage I saw to using the Lazy Loader that I had implemented was that it would do a small reload (with spinning wheel) going both forward and backward through the collection.
I realize I've been completely slacking with the development of my upcoming app. A large reason is I was just not pleased with how it was functioning.
What is WAS set up to do was connect to a cloud database, download an audio file, and play that audio file for the user. I was finding that it was too slow to obtain the sound file, too slow to download it, creating sometimes 30 second waits for the customer before the audio played (depending on WiFi or cell reception). I found this to be unacceptable. This was causing me to ignore the problem, and not continue working on this project. Then I had that AHA moment where it all became clear on what I should do.
So NOW this is how it is set up:
- I created a local Core Data store to house the sound files.
- Whenever the app is initially launched, the app does connect to the cloud database, at which time it searches the local database for the audio name. If it finds it, the file has already been downloaded and nothing happens. If it does not find it, then the file is downloaded, added to the local database and then played.
- Subsequent button pushes will play a random sound file from the local database
The search is really fast as all it downloads initially is some text and does the search for the name. Now that I've got the functionality going the way I want it to I will focus on the aesthetics of the forms. Making them look all pretty and such.
Now I have to figure out how to create and populate the local version of the database with the sound files that I want to be included upon initial download.
I’m rewriting my first app that I wrote for my wife. The app is Susan’s Charming Trinkets.
I originally wrote this app using PList files as a poor man’s database. These PList files held the location and image names to download to the app for use in the Collection View and show list.
I am reconstructing the app to utilize the Parse database to do this as I feel it both more secure than a PList on a web site, but also gives me a chance to learn more about connecting to a cloud database.
What will happen is the app will connect to the Parse database and compare what is there to what is in a local version contained within the app. It will then download anything not found locally and from this local database will be populating the collection view and show listings.
I’m pretty excited about doing this change. I am also trying to utilize best practices and compartmentalizing the different functions so I can re-use the functionality in other apps I have in mind.
Now that I’ve got it successfully reading from the cloud database in its own class, I need to take what I pull and compare it to what is in the local db, and then add them if they are not found.
Good times.. good times.
