I have an iOS app that has over 100 images pre-stored in it. I want to have a system where all the images are saved online and picked by the app. Other then maintaining an own server, what other online options are available to save and retrieve such amount of data. And what are options available to save high scores of the iOS application online?
Parse could be made to work to save and access the images.
Game Center is great for high scores and Crystal, Geosophic, and Plus+ are all alternatives as well.
you can integrate apple's iCloud in your app to store any data.
this is the link-https://developer.apple.com/library/mac/documentation/General/Conceptual/iCloudDesignGuide/Chapters/Introduction.html
for store high scores you may use game centre.

I am beginner to building Apps with React Native + Redux.
I am trying to create an App family budget. It's almost done.
BUT I have two questions for them who already created these kind of apps.
What is the best way to save data? I want to save it (data: expenses/dates/category etc) on devices iOS (not database) if it's possible. I think it does not take a lot of memory. I've read about AsyncStorage, but not sure about it. Is it still present after reloading App/Phone?
How to share data between two users? I want to make a function, like sharing the budget between family members.
I will be very grateful for the recommendations and suggestions, maybe even for some good articles with explanation.
Thanks!
If you are using redux, you can use redux-persist to store your state on devices.
To share data between devices, you probably need to implement a remote server (cloud), which receives budget changes and propagates them to other family members.

If I wanted to make an app that allows users to add their own photos to a UICollectionview what method would I use? Also, how could that be added to Firebase's real-time database?
You need to give your users access to the camera and photo library.
You wouldn’t use the Firebase real-time database, you could use the Firebase Storage module, but I would use a product like Cloudinary, which allows you to do nice things like centring, resizing, facial detection etc.

I would like to know what are the best practices regarding, Modeling data when no network connection available, if the app you are building is cloud computing based, but still you want to be able to have basic functionality and I guess some persistent data?
PD: I am kind of new to IOS development
UserDefaults is okay for small bits of data that don't change often, but as it has to rewrite the entire user defaults dataset to a file each time a change it made, it is not robust enough for anything of volume or with frequent changes. For that you would want CoreData or a third party open source solution like Realm.io.
You can try to using the 'cache' where you store temporary data.
One way to achieve this is NSUserDefaults where you set a variable (let's say users profile photo) and when the user opens his app again, the image will be loaded even if there is no internet connection since its cached. Hope this helps!

I'm creating a social media app.
I want to know a way to cache a users profile picture once downloaded from the Parse network and then each time the app is loaded check if an updated picture has been found and load that one, then cache that one.
I have no idea how to approach this, does anyone have any ideas?
There are plenty of third-party libraries for caching you can find on Github, or you can simply use NSUserDefaults or CoreData to save the pictures(or really anything) to disk. To check if a picture was modified, you can give the picture an identifier, compare it with the response from the server, and re-save the picture, or do whatever is needed.

My app has to integrate uploading image to set it as profile picture. The thing is all the images has to be stored in web services.
As web service has not been yet created. what is the best way to store images for temporary purpose so that i can integrate it easily when i have been provided with the backend.Sample tutorials can be helpful
My best idea is to use FTWCache (https://github.com/FTW/FTWCache) and cache it localy. Later, using webservice, you can still use your already written cache mechanism to implement NSURLConnection with caching. Profit! ;-)
