How to compile JRTPLIB for ios - ios

I built a project for sending or receiving audio data and tended to use RTP protocol. So I'm trying to compile JRTPLIB which I have downloaded from the web,it is written by C++,but I have no idea.I am new for these.
Does anyone know how to compile JRTPLIB which is able to use on ios? I would be very grateful if given the detailed steps.

How do I send messages from my swift file to Unity (NOT from Unity to swift)

I have been having the hardest time watching tutorials and reading documentation on how to bridge Unity and Swift together. It seems most people are looking for a way to have Unity send messages to the swift file. I am looking for the exact opposite. I would like to specifically send screenshot detection messages back to my Unity project.
So far, I have tried using the NotificationCenter.addObserver methods.
Combined with the built-in "UnitySendMessage" function (in the XCode main.mm file) I was expecting it to update my Unity project with no problem.
Is there anybody else that has achieved this?

How to add .h and .so files to iOS project

I have to make an app in Objective-C (iOS) for handle a stream video from an ip camera.
After lots of research I have not idea where to start :(
RTSP protocol is difficult thus i looked for a library and i
found these
the site where i download it said that the library is for macOS.I'd like to know if is possible add .so library to my xcode/iOS project, if so, how do it?
Or have you other solutions for RTSP stream in iOS?
Sorry for my bad English.
Thanks in advice.
No this is not possible, the .so file is a binary and compiled for the x86 (x86_64) architecture.
iOS device run on an ARM architecture.

How to compile FileMQ in iOS?

I want to implement FileMQ for file transfer from iOS to android in my iOS app.
I tried the steps given here but it causes errors at many steps. Also I need to know how should I use the downloaded library.
How should I compile FileMQ for iOS and use it?
Any information in this regard is appreciated!
I downloaded a C version of the library from the link mentioned in the question and compiled it on linux machine. I made some changes in the headers to make it iOS compatible as the headers were generated for linux. Now I am using the same copy in my iOS project.

How do I build a Cocoapod framework for swift, while keeping implementation details hidden?

I am trying to build an iOS swift framework to display encrypted photos. Photos are sent by my server (something like a hashed binary file) after calling a specific API with specific details. I will then decrypt the photo, and display it to the user.
Correct and point me in the right direction if I am wrong, but swift only allows frameworks - meaning no static library. And this will expose my implementation details (such as the method to decrypt my photo).
What I would like to achieve is to create a cocoapod distributable framework for paid developers to implement (once they subscribe to me). It is supposed to expose simple public APIs, and hide implementation details.
I have tried various ways to achieve that but to no avail. I would really like to keep the implementation to swift codes only, with minimal Obj-C codes.

But I cannot seem to get it to work. Any idea if this is possible?

Stupid idea, i'm able to see the framework's implementation details within the other framework...
Build a swift framework, and build an objective-c framework as a wrapper
I cannot seem to get this to work either...
I have been working on this project for about 2 weeks now, and have been all over Googling for it. Just in case anybody would like to try, you may try to do the following and check if it works.
Cocoapods Friendly Framework
Implementation Details Hidden
Uses Alamofire (or any public framework that connects to internet)
Any help would be appreciated, thanks!

Qt for iOS development: File read and write

I'm using Qt5.5 for iOS development.
I'm wondering how to find and open a file in an iOS device to read and write using Qt5.5. As I know, there's no such file tree structure in iOS. When I download a picture, for example, I even do not know where it locates. But I can see it in apps.
Is there anyone can help? Thanks very much.
I am no expert with Qt, but I believe you need the QStandardPaths class.
iOS is no different to any other platform that stores files in certain pre-defined locations.
