I am new to WebRTC stuff. I cloned the webrtc_ios main branch, and I built the framework as instructed here with the python script for arm64. When I add this to my Xcode project as a framework, everything is fine. Project builds, I can import files using <WebRTC/...> syntax.
However, I need to use RTCMTLRendeder.h file. Building a framework with python script leaves some of the header files out. (When I take a look at WebRTC.h inside the built framework, I can see that this file is missing) How can I include all header files that actually exist inside /webrtc_ios/src/sdk/objc/components folder while building the framework? I can see RTCMTLRenderer.h and .mm files are in that folder before using the build script. When turned into a framework those files don't exist inside the framework anymore. Why? And is there any other way to actually copy those files into the project as well?
Turns out you need to create your own, long renderer class which does not inherit from RTCMTLRenderer at all if you want to render on Metal view manually in a Swift/ObjC hybrid project (at least this is how I solved it). That class does whatever RTCMTLRenderer does, and grabs pixel buffers from RTCVideoTrack through an RTCVideoView.
I have somehow managed to get the Xcode project file for "My System" in a different folder from all the other project files. Everything works but is there an easy way to get the files together in one folder (ie. either by moving "My System.xcodeproj" into the lower folder or moving all the other files up with it in the higher folder.
If I made this change, what parameters I would need to change inside Xcode.
I'm using Xcode 11.3.1 on Mojave and Objective-C (no storyboard).
I'm not sure if it is worth moving these or whether I should just leave it.
File and Folder Structure:
The arrangement shown in your screen shot of the Finder is correct: a project folder, containing the project file (xcodeproj) along with a single folder that contains the actual code files. That is the standard. Don't mess with it.
Actually you shouldn't even look at it. Look at your project through Xcode, and let Xcode worry about where the files "really" are. Under no circumstances should you touch any of these files in the Finder or you will risk breaking the project entirely.
I'm putting a custom plist file (GoogleService-Info.plist) into my Resources directory, but it isn't getting copied into my built project. I can go into XCode and manually add it through "Copy Bundle Resources", but I need to get this running without manual steps.
I can't just use <resource-file src="src/GoogleService-Info.plist" /> in my plugin.xml because I'm building for a couple different widgetIds - I have 2 versions of this file that I switch out, depending on my widgetId. I have the copying and renaming automated with a hook to get the right file into Resources/GoogleService-Info.plist.
How can I get the file I put into Resources included?
The cordova-ios project has code to get the resource files included in the XCode project files, and you could replicate that, but I ended up with a workaround:
Copied my file to a consistent name in a before_prepare hook
Used a resource-file tag for the new name in my plugin.xml
I have created a sample application to perform bump distortion, using the GPUImage framework. I added this framework to my application, but I'm seeing the following error
Lexical or preprocessor issue 'GPUImage.h' file not found.
I have added the -ObjC flag to the Other Linker Flags, but I'm still seeing this error. How can I solve this problem and get my application to compile?
Adding GPUImage framework to XCode project could be tricky. So I haved added detailed step-by-step instructions w/ images on how to do it.
Static Compilation Method (detailed solution so we don't mess up)
This is Static compilation method. In this basically we will compile the framework using ./build.sh file. And simply add it to our XCode project, then configure XCode to properly use it.
Download GPUImage from Github and extract it (or just clone it).
Go to the GPUImagefolder in terminal
Run ./build.sh
Note: This will compile and create ready-to-use binary for all the sdks on your mac.
build.sh creates a folder called build and generates compiled binaries and dumps them to folders like: Release-iPhone, Release-iPhoneOS, Release-iphonesimulator etc folders.
For iPhone use Release-iphone (This also works for simulator).
Copy (not drag-drop) Release-iphone to your XCode project's root directory so that we have a local copy of framework.
Now iPhone drag-and-drop Release-iphone onto your XCode project. Make sure to check "Copy to .." option.
Note:
This Release-iphone folder contains two sub-folders: include and lib
include folder contains all the header .h files
lib folder contains compiled binary version file called libGPUImage.a
We now need to simply configure XCode to use .h and .a files.**
Select your project in the project explorer > Project name under Targets > select Build Phases > Expand Link Binary With Libraries
Add the libGPUImage.a to Link Binary With Libraries section. You may want to Right-click on libGPUImage.a then Open in Finder and finally drag-drop it.
While we are at it, also add the following GPUImage's dependent frameworks/ libraries
CoreMedia, CoreVideo, OpenGLES, AVFoundation, QuartzCore to Link Binary With Libraries section
Now, lets configure .h headers.
Select your project in the project explorer > Project name under Targets > select Build Settings > and type search paths to see search paths section.
Open Headers Search Paths by clicking on the value field.
Drag-and-drop the lib folder to that popup. Note: If it shows absolute path, change it to looks $(SRCROOT)/path/to/lib/. (You should have the framework relative to your xcode project see step 6).
Repeat 11 & 12 for Library Search Paths as well.
Additional tips: You can add .h files to Library Search Paths or Headers Search Paths, you can make them Recursive. I have a main root-folder called Dependencies folder where I keep all the dependencies like MySDK-framework including Release-iPhone. And I just have one search-path at the Dependencies (root folder) and made it recursive.
Did you follow all of the instructions from the Readme on the project page? From the installation instructions:
You'll also need to find the framework headers, so within your
project's build settings set the Header Search Paths to the relative
path from your application to the framework/ subdirectory within the
GPUImage source directory. Make this header search path recursive.
If you're seeing the above error, it means that you did not point the Header Search Paths at the right directory where you've installed GPUImage relative to your project, and / or did not click the checkbox to the left to make those search paths recursive.
I show some screenshots of where you need to go to set this in this answer, which explains something similar for the Core Plot framework. The same principles apply, only you need to find where you installed the GPUImage framework at.
I add relative path to "Header Search Paths", but there is still a error that is "not found".
Then, I add path to "User Header Search Paths", and it works.
May help you.
finally, I realized the KEY WORD is relativeļ¼
I put GPUImage source files in my project root dir:
before I solved the problem, I add Header Search Paths is:
$(PROJECT_DIR)/GPUImage/framework
$(PROJECT_DIR)/GPUImage/framework/iOS
and make them Recursive, but error is still there, So I changed Paths to:
GPUImage/framework and make it Recursive, then it works.
Hope it helps.
My team recently renamed the project of an Objective-C iOS app in Xcode and we've determined a larger problem to be the cause of the .mom file within the momd directory to be named wrongly.
Example (not real names):
Our project used to be named "ChinaTown", but was renamed to "Chinatown". Thus inside the Chinatown.momd directory is a ChinaTown.mom file.
How can we ensure that the .mom file within the momd directory is of the correct name and case?
Fixed by recreating the data model and deleting the old one. Reference stackoverflow thread
