data-sharing

问题 One of my client's inventory management project supports online as well as offline mode to manage huge inventory data and is built using Xamarin.Forms & sqlite-net. Now, the client wants to create another similar kind of app and wants us to use the same local db of the first app. The actual functionality he needs is that if I have data in one app then it can be shared to the second app and vice-versa. Like, if I'm logged into the first app then user automatically gets logged in to second app

问题 I'm making an app for a final project for class and I need to share strings, integers and floats throughout different views in my application. I have to create an app that a waiter/waitress would use on the job. I need different views for different types of items to order (beverages, appetizers, entrées, etc.) and need to keep the items chosen, the price and the quantity of each accessible to different views to keep a running total available in each view (one view for each type of item) and

问题 I'm new to iOS. I need to create a small app that allows registered users to share particular data between them and I'm looking for the best solution. I know I could create a server, which handle user authentication, pushing notifications and sharing data between them, but maybe there is a simpler and better way. I saw iOS 8 introduced CloudKit, but I haven't a chance to test it. Do you think it could meet my expectations? Thanks for help. 回答1: You could take a look into Parse or other same

问题 I have two executables written in C++ on Windows. I generate some data in one, and want to call the other executable to process this data. I could write the data out to a file then read it in the other executable, but that seems rather expensive in terms of disk I/O. What is a better way of doing this? It seems like a simple enough question but google just isn't helping! Let's say the data is around 100MB, and is generated in its entirety before needing to be sent (i.e. no streaming is needed

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

What is the best way to share data between users of the same app - like a shared list of items that only 2 specific users can see and edit. My question is about the data transfer part - is there any service or
