How to change Xcode project entirely? - iphone

I have an xcode project boilerplate codebase that I am using for my third project.
It has class prefixes from the last project and also the name of the previous project everywhere. plist, pch, project name, schemes, build targets, folders etc.
Also the copyright text in the classes need to be changed to the new one for the new client.
Is there a consolidated way to change all the identity from my previous project to the new one rather than doing it one by one?

You can use Xcode's refactoring tools to rename classes and other identifiers wherever they occur, but you still have to do each identifier individually -- you can't change all the classes at the same time. Find and replace should take care of things like copyright text.
The Edit->Refactor->Rename... command (or control-click on a name to get to the Refactor context menu) is the best way to rename things like classes and variables because it will catch cases you might not have thought of. For example, renaming a class will change the name in storyboard and .xib files.

Naming convention having two targets in the app

I had two target for my application. One free and other is for paid.
Now i need to add different icons for both target. Now the problem is that i can not used apple naming conventions like now i use icon_free.png and icon_paid.png.
My Problem when i add 512px icon then will iOS will automatically pick the correct image for each build
There are two ways.
First option: You can use apples naming conventions. Just store the icons in different sub directories. When creating the second target one suitable sub-dir was created. However, you can create a new one.
Place the files with default names in each of the directories.
Create separated groups for them in your navigtor tree in xcode. Upon creation of the second target that should have been done anyway. So you can have both versions of the icon with the same name at different branches within your navigation tree.
Then go to the copy build settings of each target and make sure that the appropriate version is included for each target.
Second option: Alternatively give the icon (and default etc.) files different names and name them explicitely in plist.info. And plist.info then exsist for each of the targets. For plist.info xcode should have created separate files anyway. You find it on the info tab of the projedct settings close to the build obtions tab.
In general I found it is good pactice beeing neat with separate folders. After hasseling around with difficult problems when having two targets with newer apps I always have one sub-dir with all the shared resources and one for each of the targets. It makes it easier to boundle the copy and compile settings for each of the targets accordingly.
Just one more: When ever you apply changes to the bundles in this way you should delete the apps thoroughly from the simulators and test devices. If you don't then you may run into situations where the root cause is difficult to find. That is that there are old versions of some of the resources on the device. They will not be updated along with new releases. You will then have as best missing resoures on 3rd party devices and in the worst case you will chase errors and all what you try does not have an effect on the device/simulator because the locally existing resource is not being updated. Difficult to figure out.

how do I reference a separate project in xcode 4?

How do I reference another project which has code I wish to leverage in XCode 4. In particular I'm trying to make use of the NSDate extensions from here.
Some notes:
I was assuming I should probably reference rather than trying build a framework
I tried copying the existing "Hello World" xcode project file across into my project, however this didn't seem to work
Do I need to create a new "Target" based on "coco touch static library" option?
Then would I need to Edit the current Product Scheme so that when I build the new target would build
What do I need to do on my project side exactly - should going Add Files, and choosing the extensions Xcode Project File be enough?
thanks
I was assuming I should probably reference rather than trying build a framework
yes, reference and link with it, unless you need only a bit of it. at this stage, separating the bits you want may be an advanced topic (depends on the lib's layout/depends as well). you should prefer to reference and link because it will normally minimize your maintenance time, especially if you use it in multiple projects.
I tried copying the existing "Hello World" xcode project file across into my project, however this didn't seem to work
you don't create a project, you add the library's xcode project to your app or library, set the lib as a dependency, add the library to your search paths if needed, then link with the library.
Do I need to create a new "Target" based on "coco touch static library" option?
no
Then would I need to Edit the current Product Scheme so that when I build the new target would build
no. you configure it as a dependency. you may need to alter the lib's build settings if there is a major conflict, which the linker or compiler would point out.
What do I need to do on my project side exactly - should going Add Files, and choosing the extensions Xcode Project File be enough?
start with the process outlined above.
There is no reason to bring in an actually project. Either you can bring in the source files themselves and you could even use the same exact files instead of copying them if you want. However, if you have more than just a few files, and you don't think you will be changing the code much, then creating a static library would probably be the best option.

two projects in xcode4 workspaces (#import failure)

I'm really struggling to get this to work in xcode 4.
I have one project that I will reuse in many applications (networking) so I create a workspace and add my two projects. So far so good....
This is where it fails..
#import "JSONRequest.h"
For no apparent reason. It auto completes the file name of the header file. I thought this had something to do with the "scheme" (also new in xcode 4) so I've tried to add my networking target in the build phase. Changing order of them... set "Shared" under Manage schemes.. I've tried so many different combinations of the settings without any success.. And the error message is get is:
JSONRequest.h: No such file or directory
If you have a clue, please let me know.
You can add the header or source folder of your project you're referencing to your Header Search Paths.
Click on the target that's importing JSONRequest.h.
Click on Build Settings.
Enter "Header Search Paths" into the search box.
Double click on the value cell.
Click the + sign.
Set the path to the project you're referring. Let's say it's called JSONlib. The path is relative to the root of the referring project (the project that's using JSONlib). For example: ../JSONlib/src/headers/ or wherever it is that the .h file lives.
Click done.
Clean and then build.
You'll find more info about this problem in the apple developer forums. Best of luck.
What are you really trying to do?
If you have an entire Xcode project you intend to share between different products that usually suggests your project builds one or more targets (such as a framework, etc.). Therefore, your "shared" project should be able to build the framework on its own, irrespective of the workspace it's contained in, right?
Let's assume it's a framework. In most cases, Xcode can figure out the dependency by simply adding the framework product to the Link build phase of the (assumed) app using the framework. Done. Xcode should know to build the framework project's target first, since it's linked against when building the app project's target.
So your problem is likely just a matter of knowing where Xcode is looking to find files. Since projects within workspaces share that workspace's build folder, they can all "see" each other. But in the case of a framework, A simple import by file name won't cut it. You'd need:
#import <MyNetworkingFramework/MyNetworkingFramework.h>
Since you're including a specific header (JSONRequest.h) (which must be one of the public headers in the framework target's copy headers build phase), you'd need:
#import <MyNetworkingFramework/JSONRequest.h>
If your "shared" project is not a framework, you'll need to amend your question to include a more thorough description of your two projects and their targets.
This worked for me,
In build settings --> Header Search Path --> Add below entry
$(SRCROOT) and mark it as recursive. If above not worked you can also try following way, <path-of-other-project> and mark it as recursive. Hope this helps to you ! (You may require to clean or restart the workspace)

Same code base for iPhone/Desktop app

I have an iPhone/iPad app that I want to port to MacOSX. Most of my objective C classes should work just fine as long as they do not contain UIKit stuff. Obviously the interface will be different.
What is the best way to do this in Xcode? Start a completely new project? Add a new target? How can I keep the different platforms in sync? Should I just use git with multiple branches?
I've had difficulty setting up a unified project with different targets for the two OS types, so I generally split this into two projects that share source files.
For an application that will be targeted Mac and iOS, I tend to create one directory for the application. I place the two projects within this, and set up one directory for shared source files, one for iOS-specific stuff, and a third for Mac-specific stuff. This way, you might have different projects, but shared files will update between them as they are changed. The only time you manually have to sync the two is when a new shared file is added to the application and must be added to both projects independently.
You should be able to restructure your existing project to support this without much trouble.
You can also simply add the files from one project as references to the other one. Simply drag them from the source project (where the actual files reside) into the other project. The dialog will ask you whether you want to copy the files. Choose no. This will make the second project point to the files in the first project. Edits go into both projects.
Be careful with this, though, as there are a few differences between APIs in iOS and MacOS, even if they are called the same.

XCode: Linking projects inquiry

I have 2 projects and I want to use in the first project, a class (i.e. view controller) of the second. Instead of importing all the files of the second project in the first one, is there a way to link it like a framework or library?
I tried the following unsuccessfully:
Dragged-dropped SecondProject.xcodeproj and checked SecondProject.app as a target
Added it as a dependency project in the first project dependencies
Pointed to the header files by adding in the "Header Search Paths" a path pointing to the second project which I copied in a subfolder of the first project.
When I include "SecondProjectViewController.h" I get no errors but when I try to instantiate it I get the "OBJ C referenced from" error.
Any help is deeply needed and appreciated! =)
F.
As an experienced developer I would suggest not sharing code this way across projects. The simple reason is that changes in one project will then directly effect other projects, often rendering them un-compilable. For example, if you share a controller class and decide to implement a change with a new import, then any project that uses that class will be broken until you open then in xcode and ensure that the imported class is available.
A better method is to compile your first project as a static library or framework. I'd also recommend ensuring that it is version some way. For example, in my projects I create static frameworks and store them in a directory called "v0.0.1", "v0.0.2" etc.
The framework can then be dragged and dropped into a second project to use it. The second project then refers to it via the directory path. The advantage of doing this is that if I then change the first project, the second one if not effected by the changes until I choose to update the frameworks path.
Sharing files between projects will work for small cases, that being 2 or 4 projects, but once you have more than that it rapidly becomes un-manageable.
You have only a few steps to go:
4) in First project, click the disclosure triangle in the Groups and Files section for the Second Project reference. this will display the targets of Second Project.
5) Drag the target reference (e.g., static library) from Second Project to the target in First Project's link phase.
That should clear up all the linker errors for the symbols which exist in Second Project's library. Of course, you'll have to remove those sources (based in second Second) which are compiled and linked from First.
Managing static libraries for huge codebases is dead easy this way (although I prefer the build up to the minute (as well as several build variants), and don't reference archived binaries as Derek does). Learning to minimize changes which break builds takes time to learn. dynamic libraries are a bit different - depending on their distribution, you may want to version (as Derek outlined). It's good to share, but you should put the shared exported symbols in a library, which is a dependency of both apps. Just be careful not to add too much unnecessary objc symbols to the library - objc symbols and their references cannot be stripped from the final executable and they will cause runtime collisions if they appear in two images (dylib, app, static lib) within the same process.
You can add the view controller's files to your 1st project regardless of where they are on disk -- the project will make a reference to their location.
