OK, I know this question seems pretty easy to answer, or maybe documented, but I'm honestly 100% confused around the subject, with effects as... silly as submitting an application for review by Apple and then realizing (by the logs they sent me back), that the Framework wasn't there (actually, it was... but my Cocoa app was looking for it elsewhere).
Ok, so... let's say I have a framework with like 100 different classes I mostly use (which I do have), what settings should I use if I want to "bundle" my Framework with my apps (and copy it in the framework folder of the app bundle)?
Build Settings -> Installation Directory? (of the Framework)
Build Settings -> Header Search Paths? (of the App)
Build Settings -> Library Search Paths? (of the App)
Build Settings -> Framework Search Paths? (of the App)
use #rpath? and how?
anything else?
Given that I mostly have issues "linking" my frameworks to my apps (the framework compiles great, but there may be a runtime error occasionally when the app using it tries to run (which I... occasionally manage to solve - but without actually knowing how... lol)), what would you suggest?
Third party frameworks should be included with the app in a Frameworks directory of the app bundle.
Add a new copy files build phase and specify the Frameworks directory, then add your frameworks to this directory:
You may also need to tell Xcode where the frameworks are by adding a Framework Search Path like "$(SRCROOT)/MyFrameworks".

I am a new guy in OC programming. Now I am involved in a framework development project.
I know the framework works as a library, which contains a group of methods. It's not an application that can run on devices.
Actually, our framework will work with customer's application. We want to investigate what happened inside our framework when customer's application crashed. So I want the 'DSYM' file of our framework, instead of an application.
As far as I know any iOS application does have corresponded 'DSYM', but I didn't find the 'DSYM' of our framework.
Does iOS framework project have 'DSYM'? If it does have, how can I obtain it?
By the way, I am using Xcode 8.1.
Thanks!
According to my observations, .dSYM files are generated for iOS dynamic framework built with Release configuration only.
After build succeeds, the debug symbols files can be found at these paths, for a device and simulator, respectively:
<Build_Root>/build/Release-iphoneos/<Product_Name>.framework.dSYM
<Build_Root>/build/Release-iphonesimulator/<Product_Name>.framework.dSYM
, where
<Build_Root> is usually a subdirectory within Derived Data directory;
<Product_Name>is the name of your framework.
Yes, you can generate dSYMs for dynamic frameworks. There are a few relevant build settings that control whether and where these files are generated:
DEBUG_INFORMATION_FORMAT = dwarf-with-dsym,
DWARF_DSYM_FOLDER_PATH = "$(CONFIGURATION_BUILD_DIR)",
DWARF_DSYM_FILE_NAME = "$(PRODUCT_NAME).dSYM"
Obviously, you can set these to whatever you want, either in your project's build settings in Xcode (the project.pbxproj file) or as arguments to xcodebuild (depending on how you generate your framework).
DSYM (Debugging SYMbols) files generally store the debugging symbols for your app. And if app crash any where symbols replaced with appropriate method name so that it could help developer in a readable form. And for that you can use the crash log and they can be find in the iPhone where the app is installed. Each app and device have their own crash log.

It's getting quite frustrating with Xcode 5 here. All I'm trying to achieve is embedding some custom Cocoa frameworks into my project and create two versions of the app, one for the Mac App Store and one for a custom Online Store (so that when building for the MAS there'll be a folder called Debug (MAS) so I can distinguish it from the other version).
I embedded three frameworks into the project (only god knows why only one project can have another one embedded at a time, to hell with this limitation) and added their products in the "Link binary with libraries" and "copy frameworks" build phase. The finished built products are at the default location in the Library.
Now here's the thing - every time I'm using custom build configuration files other than "Debug" and "Release", the frameworks are NOT copied to the custom build folders but instead just go into "Debug" and "Release" regardless of any build options of the main app. Also, the frameworks are always built using "Debug" and are no longer connected to the current build mode (test, archive, etc.). To cut a long story short, this is a huge mess with file paths and obviously a lot of bugs concerning custom frameworks and custom build configurations.
Now my question is - there has to be an official or working way of maintaining an Xcode project that is both distributed over the MAS and a custom online store (two versions) and has at least one custom framework embedded. How do all other developers have solved this problem, I feel like I'm doing something fundamentally wrong and if I do, sorry for putting the blame on Xcode but something's for sure: Xcode's path management with external components is a chaos and the cause for unlimited mailing list and forum posts...
The answer is to create separate targets for the MAS & non-MAS app. You can add additional targets to build the custom frameworks and make the different targets dependent on each other (as necessary). Once this is all setup (properly) then building any of the targets will build any dependent targets (with the same build flags). And AFAIK there's nothing preventing an Xcode project from including multiple sub-projects so I haven't a clue why you believe this to be the case.
As far as I see every time I make a change, for example the value of a configuration variable, I have to
Make a copy of the change in each project (webapp, Android, IPhone, etc.)
Build each project
Distribute each project (besides the webapp)
I have found PhoneGap build which seems to be a great solution for the mobile part. But it's still beta and it doesn't solve everything. I still have webapp's code, which is not exactly the same.
Do you know techniques, tools or tricks, which help to improve this process?
Thanks in advance.
We are currently developing a web/Android app using PhoneGap and Sencha Touch (iOS is coming soon). So far our approach is as follows:
We have one project per platform plus several additional toolkit projects.
One platform is "primary", web in our case. This is what developers mainly use to develop and test the app. We're using jsTestDriver for testing.
During the build, the app is packaged for web in the first step. We're producing several artifacts here (.war file, tests in a .jar file).
"Secondary" platform projects do not include the source code. It gets unpackaged and copied to the right places when projects are built. This also includes tests from the primary platform.
Platform projects contain some additional code - normally only testing code, app code itself is currently cross-platform (not sure if it will stay this way).
So we're doing it mainly through advanced build scripts. We're using Maven for web and Android. iOS is coming soon (into our work, I mean), so we'll be looking for some sensible build tool there too.
We're building our projects using Hudson continuous integration.
What I have to admit is that this whole environment (multi-project Maven builds, JSTD, multi-node Hudson) is a hell of a setup, took quite an effort to figure it out.
I recently did some research on making a cocos2d app for iPhone/iPad AND Mac. I have done the iPhone/iPad route but have never done it with a Mac target. It appears that some people have added it as a target but mentioned that it is finicky and others have suggested making a separate Cocos2d Mac project that uses the same files. Any wisdom to impart here?
I believe it is absolutely crucial to have both iOS and Mac targets in the same project. Otherwise you'll spend too much time keeping one platform in synch with the other, until eventually you either manage to create a good (but still time-consuming) workflow - or end up neglecting one of the two platforms.
Ideally the code base should make as little use as possible of compiler macros. You'll want to compile both iOS and Mac code even if it's not being used for one platform. So having some classes or methods that are #ifdef'ed to Mac, others to iOS, will more often than not lead to compile errors when you switch targets. That means wrapper classes, so that you can write the same code regardless of the platform, are essential.
Right now, Cocos2D doesn't offer you to create iOS & Mac targets in the same Xcode project. The way to get there isn't immediately obvious either, because each target requires its own build settings for: Base SDK, SDK Root, Deployment Target, Architectures and possibly Compiler version. It gets worse if you also want to use 3rd party libraries (Box2D, Chipmunk, etc) because in some cases you'll be forced to create iOS and Mac specific targets for those libraries as well - if only to ensure that the library is built with the same compiler as the project's target, otherwise you can run into the strangest build or runtime issues.
I've had issues getting these platform specific targets to work within a single Xcode project without Xcode complaining or otherwise misbehaving. I haven't tried it with Xcode 4.1 and 4.2. By that time I had created .xcconfig files to host the build settings. The .xcconfig files may or may not be necessary with the more recent Xcode versions but they definitely make managing multiple platform-specific targets easier.
Long story short, the best and easiest way to do cross-platform development with cocos2d-iphone is by using Kobold2D.
Most of the 15 template projects have an iOS and Mac target in each project, you just need to select the corresponding scheme, then hit build & run. The most commonly needed platform-specific code (processing user input) is wrapped in a platform-agnostic, simple to use wrapper class KKInput.
Disclaimer: I'm the developer of Kobold2D. There's a slim chance that I may be biased. You should try Kobold2D anyway. :)
I have had some issues with the AWS IOS SDK framekit, since it was not built to work with OSX apps. I found a modified version of the SDK that Brad Larson created.
The directory structure looks something like:
AWSiOSSDK.framework/
src/
--Amazon.Runtime/
--Amazon.S3/
..
--AWSCocoa/
----AWSCocoa_Prefix.pch
----AWSCocoa.xcodeproj
----etc
--include/
So if I go into the xcode project, and build AWSCocoa it compiles. But when I look at the timestamp on the AWSiOSSDK.framework, it hasn't changed. So I don't know what compiling this AWSCocoa gets me, or where I can find the files it creates. So assuming that building AWSCocoa.xcodeproj is supposed to build a new version of the framework compatible with OSX development, where do I find and link what I've built?
The AWSiOSSDK.framework bundle is a precompiled framework, probably left over from my earlier experiments in making a Mac version of this (since you can't use frameworks like this with iOS, only static libraries). Ignore that.
If you are using Xcode 4, your built framework will be created somewhere in your ~/Library/Developer/Xcode/DerivedData/ directory. To find where it lies, go to your project navigator in Xcode 4, expand the Products group, right click on AWSCocoa.framework, and select Show in Finder. This is no different from any other third-party framework you would compile.
Nominally, you'll want to add this framework as a target dependency in your application so that it is built alongside that. You'll also have to make sure that the framework is copied into the appropriate location within your application bundle so that it can be used by your application at runtime.
