I'm using the Facebook-SDK to make some FQL queries. Now I want to know how much of the requested data has already been transferred to the app to visualize the loading process in a progressbar.
So I used this https://github.com/nyankichi820/FBRequestConnection-FBRequestConnection_progress plugin which extends the FBURLConnection class to provide the progress of a data transfer.
The problem is, that I included the Facebook-SDK as an XCode framework into the project and the header file FBURLConnection.h which is necessary for the plugin is not published in the framework and cannot be found.
So how can I include the header file FBURLConnection.h into the frameworks visible headers so that I can access it? I dont't want to include all the FB-SDK files, I wanted to do this by relying on the XCode framework structure. Thanks in advance.
You should probably include the source of the framework yourself manually or much more simply using cocoapods.
Here is the github link to the SDK source: https://github.com/facebook/facebook-ios-sdk
The official cocoapod is named "Facebook-iOS-SDK", if you decide to go that route. I recommend doing this as it is much simpler to install the SDK and update it later on. Cocoapods are very nice for external components in general and will almost certainly save you time and frustration in the long run.

I'm making a framework (an SDK) that will be made public. I'm thinking about a situation when it's not distributed via Cocoapods / Carthage, but rather via a simple Downloads page.
In the SDK I need to provide users an opportunity to login and share via Facebook, so I would like to use appropriate Facebook SDKs (FBSDKLoginKit / ShareKit, I assume). But if the end user of my SDK will also have these Facebook SDKs (or any other duplicate dependency), there will be a conflict.
What is the proper way to handle this situation without using Cocoapods / Carthage? I believe, one way is to avoid including / statically linking dependencies into my framework, but rather have end users download dependencies separately, but maybe there is another way around it? Making people download tons of libs from different sources isn't very convenient.
The question isn't about Facebook SDKs in particular, but about a general situation with third-party dependencies when developing a framework / library.
P.S. I found this question: Integrate Facebook SDK inside my iOS Framework. But it's specifically about Facebook, and it might be outdated (a lot of stuff happened in the iOS world since 2014).
UPDATE: the SDK will be closed source.
You could do a combination of the two ideas you suggested:
Don't include the other SDKs directly in your framework, but have them in the same project when the user downloads it. That way, if the user doesn't already have them, they can copy over all of the frameworks that they need. And if the user does already have them, then they can just copy your SDK by itself and have it just work in their project.
This combination also allows you to include tests and samples in the download. Then users end up downloading a complete, functioning project that they can try out before integrating it with their own code.
I want to know which is the best and most reliable method. i have looked on here for an answer but didn't come across any.
I Want to use multiple API'S in my project so please keep that in mind when answering. Any advice about the best way of doing this and most reliable method will really be appreciated. Thanks in advance!
Isit possible to download multiple SDK's into an iOS application through Xcode?
Pros of SDK:
Can be used offline
Most SDKs are small in file size
All of the functioning code is visible to you, the SDK developer can't keep many secrets
Cons of SDK:
Larger binary
More clutter in your Xcode project
Pros of API:
Smaller binary
Less 3rd party frameworks cluttering your Xcode project
Cons of API:
Can't be used offline
Tends to be a blackbox
App will need to be updated every time the API is updated
In terms of reliability, the SDK will always be functional assuming
It worked in the first place
It doesn't rely on an API in the background
You can integrate SDK using Cocoapods library.CocoaPods is a ruby gem that downloads all the third party libraries that you want for your project.
Getting a specific version of a pod is done by specifying the version number, and CocoaPods downloads that specific version for you saving you from searching through commits for it.
With CocoaPods, updating your dependancies is easily done with the pod update command.
CocoaPods also provides a central place where third party libraries can be found. This improves discoverability of open source libraries that you can use in your projects. You can use the search engine at cocoapods.org to search for pods.
I have a simple app which uses whirlyglobe framework (2.2). Otherwise, it is pretty basic program with Apple frameworks.
When I tried to validate the app (and during the distribution, Xcode complains that my app is using private API; specifically it calls "rootElement", and "attributeForFont:". I suspect these functions are part of WhilyGlobe component distribution.
What is the easiest way to remove those files from the framework? Do I need to have the source and compile the framework myself? Or is there a simpler way?
Solved. Here is what I did:
1) Searched in github repository of WhirlyGlobe and found the file that uses the functions which caused issue.
2) I did not need the functionality provided by the file that had the functions.
3) Removed the references (class instantiation) to the file from my project.
That's actually part of the KissXML framework and the implementation is in there. I suspect Apple's test is in error.
In any case, if you're not using the WMS functionality, you can probably drop it out just fine.
I've seen project such as ios-universal-framework, but I want to know why XCode iOS does not natively support having a framework. Is it some kind of legal issue. The static library option is not good enough because I want to be able to use .dylib files in my framework.
A little background on what I want to do with a framework. I have a project that is generated from Unity3D, and when we update, we have to manually add back all of our project changes.
What I want is to use a framework that can store most of those external libraries and resources to make it easier to upgrade our project when updates are released.
From a security perspective no code is allowed to be dynamically loaded, thus only static libraries are allowed.
It is possible to create static psudo-frameworks. Take a look at GitHub iOS-Universal-Framework.
What you need is a PosprocessBuilder as described in the build pipeline described in the Unity3d Documentation.
You can manage the Xcode configurations in this pipeline using scripts like the Xcode Zerg.
I've used one python script written by a guy called Calvin Rien that worked really well, if you want to know more about this script this blog post should give you a hint.
What you really need to look for to you automate the these steps is to look for posts of Continuous Integration using Unity 3d and iOS like this one:
Unity3d: from commit to deployment onto tester devices in 20 min using Jenkins
I'm working in a iOS project that includes a static library created by another company.
The library include an old version of AFNeworking and I don't have any source files.
Now i need to use a more recent (and less bugged) version of afneworking, but i cannot include the same class twice in the project (of course) because all the "duplicate symbols".
I understand that it's impossible replacing the version included in the library, but how can i include another version along the old one?
There is a (easy) way to refactor the entire framework before include in my project?
thanks
You'll have to repackage the static library to remove the embedded AFNetworking files.
Unpack the library with:
$ ar x libwhatever.a
And re-package it, including all files except the AFNetworking object files:
$ ar cr libwhatever.a file1.o ... fileN.o
You will then have to link your executable with the new AFNetworking static library and hope that there haven't been API changes which will break the code in libwhatever.a. If there are then I doubt there is much you can do.
I'm afraid this isn't easy to do. Very few environments allow you to link against two separate versions of the same framework at the same time, and Xcode / iOS is not one of them.
As I see it, you have three options:
1) Link against their library and use the same version of AFNetworking they use.
2) Link against their library, and manually load the newer version of AFNetworking and pull symbols from it. Be warned: this will get ugly fast and future maintainers will wonder what you were smoking.
3) Get them to update their library.
On a side note, I don't know the circumstances here, but in general they should be providing you with sources. It's a very backwards practice to provide only a static (static!) library and no way to know what it's doing inside. You'll have to sign a software license agreement and whatnot to protect their interests.
The best and most proper way of handling this would be to contact the the creator of the static library and get them to resolve the situation. They could resolve it either by updating the embedded version of AFNetworking, removing their dependence on AFNetworking, or adding a prefix for their embedded copy of AFNetworking. The last one is probably a good idea anyway when a third party library embeds a different library, because otherwise it would be impossible to use two libraries simultaneously that both include the same third party library.
You could also refactor the copy of AFNetworking that you include yourself to change the names of classes to have a prefix, although this should be unnecessary, as the static library vendor should have done this themselves already.
Lastly, you could find a different library that accomplishes the same thing as your current one but that doesn't embed AFNetworking.
