I have created one library with "Utility.h" file. I want to add that custom library to my another iPhone application. I have added the library to project "frameworks" and I have drag the library to "Library Search Path" it shows like "$(SRCROOT)/libUtility.a". I have imported the header file as #import "Utility.h". But I am getting below error message.
Utility.h No such file or directory.
Please any one help me to resolve this issues.
What is my mistake.
You have to drag the Utility.h file to your project as well along with your library.

I am fairly new to ios development - trying to use sdwebimage in my iphone project. I believe I completed all basic setups as required. But when I build, I get this error: No such file file or directory near this line:
#import "UIImageView+WebCache.h"
Yes I have added Target Dependencies
I have added libSDWebImage.a in Link Binary With Libraries
I have -all_load -ObjC in Other Linker Flags
I also tried the -force_load ${BUILT_PRODUCTS_DIR}/libSDWebImage.a (64bit mac)
My Use Header Search Paths is : $(BUILT_PRODUCTS_DIR)
I cleaned the project and rebuilt - but no use.
Build keeps failing. Again, XCode4 code completion "resolves" when I type #import "UI & hit "ctrl+space" which means the lib is visible to xcode. Any pointers will be super helpful. Thanks.
To add the needed header files to the build path do the following.
Select your project file
Select your target
Select Build settings
In the search box enter 'header search paths'
For the Release add "$(SOURCE_ROOT)/SDWebImage" (thats with quotes).
This will work when importing like this #import <SDWebImage/UIImageView+WebCache.h>
I also use SDWebImage.
In my experience I didn't do anything with the linker flags etc.
You only have to add the classes in your project and simply import the "UIImageView+WebCache.h" in your class' header like this:
#import "UIImageView+WebCache.h"
and if you want to use it on an UIImageView object, just use the method
setImageWithURL:placeholderImage:
you can refer to their github for more info
I just ran into this problem and have solved it.
The issue is that when you "drag" the SDWebImage xcode project to your project, Xcode only create a reference to point to those files needed. When you are in debug mode it's fine, it knows where to find those file. However, when you want to archive it (packing everything to be self-contained), it couldn't find it from your search path.
Although you have added $(BUILT_PRODUCTS_DIR) to your search path, but if the actual files that you downloaded are not physically located in your $(BUILT_PRODUCTS_DIR), then Xcode won't find them. This was the problem for me since my SDWebImage files were still sitting in my download folder.
What you want to do is:
1.Move the SDWebImage folders to a place where you won't accidentally delete it. Notice once you've done that, the SDWebImage project file will become red since it's physical location is moved. And it's wired that I could not delete that reference in Xcode, what I ended up doing is add that file again (choosing from the location where I just move it too). You will end up with a red SDWebImage.xcodeproj in your project navigator which you can not delete. It's very annoying but it won't affect anything.
2. If the location you move the SDWebImage stuff to is not in your $(BUILT_PRODUCTS_DIR), then you either move that inside $(BUILT_PRODUCTS_DIR) or as I do, add the path to Target -> Build Settings -> Search Paths -> User Header Search Paths.
Archive and it should work now.
I faced this same problem and was about to go crazy. Like Ravi, I followed the static installation instructions as closely as possible.
I saw the auto suggest for UIImageView+WebCache.h when I was typing #import, but it keeps throwing file not found.
In the end, it was this. In header search paths,
“$(BUILT_PRODUCTS_DIR)” - Wrong.
$(BUILT_PRODUCTS_DIR) - Right.
Embarrassed but now it's working right =)
I've been dealing with this problem for the past hour and noticed something that hasn't been mentioned: Make sure that when you up update header search paths that the "Recursive" option is selected! Otherwise the compiler will not check subfolders.
Worked for me...
I was dealing with the same problem, my two frameworks were not getting found. I tried all the suggested ways in order to resolve the error but it couldnt help. Atlast I deleted the frameworks from my project structure and reloaded them from the original project file and it worked!! Please try this if it helps, It worked for me...
I had a similar issue after pod update. If you are using CocoaPods version higher than 1.0.0 and more than one target in your project, you have to add all the targets into the Podfile.
I have a project (AQGridView) that compiles to a static library, but I can't seem to add it to my project.
Dragging in the project to my project creates a workspace, and if I try to link the libAQGridView.a file from the DerivedData directory it doesn't recognize it as a library. I'm not sure what I'm doing wrong.
This is the AQGridView project. Does anyone know specifically how to use it in an Xcode 4 project?
I do this as follows:
Drag in the static library project. If you have the static library project open in Xcode, close it now.
Select the main project in the project navigator (the project I'm adding the static library to) and in the editor, under the header TARGETS in the left-hand column, select my main project's target and navigate to the Build Phases tab.
Click the "+" for Target Dependencies and add the library icon target dependency from the added static library project.
Click the "+" for Link Binary with Libraries and add the library icon that is under the folder "Workspace".
It may also be necessary to enter a Header Search Path for the headers of the static library project if that is how the headers are linked in the static library project itself.
If you don't see the static library project as nested under the main project in the main project's project navigator, the most likely reason for that is that the static library's own Xcode project is still open. Quit Xcode and open up the main project that has the nested static library project in it without opening up the original static library project itself, and you should see it appearing as a nested project in your main project.
Xcode menu > View > Utilities > File Inspector
Select the static library file, and then set 'File Type' as 'Mach-O object code' in 'Identity and Type'.
Workspaces are supposed to make this easier, but I don't know that they do. The way I do it is create a workspace, add my main project, add my library project. Then go into the main project's build phases and add the library in the "Link binary with libraries" section and add the library. That should be all that is necessary, at least that's my reading, but it isn't. What I do is go into Xcode preferences, then to the Source Trees pane. Add a source tree that points to your static library's headers, then go back to the build settings for your project, then to the Header Search Paths key, and enter ${foo} there, where "foo" is whatever you called the source tree.
That's what works for me, though I don't know if that's the best or easiest way to do it.
Find your .a file in finder, and drag it into your project.
Select the 'copy items into destination group's folder (if needed)', and add your headers to your project.
Now, Xcode 4 should automatically link against that framework for you.
Here is what the library should look like in your project:
Follow Apple's documentation.
In brief:
Link your target against the library.
Add -ObjC to 'Other Linker Flags' (OTHER_LDFLAGS) under the target's build settings.
Also, I needed to add the library to the scheme of my main project since the library was not visible in the target's dependencies.
The Halle's answer works for me with one addition:
Check in Build Settings of the static library project the Private( or Public) Headers Folder Path value and copy it.
Add copied value to the client project Build Settings Header Search Path or User Header Search Path depending of the include directive you are using
The instructions for installing the JSON Framework seem to be for older versions of Xcode. I'm relatively unfamiliar with Xcode and I can't figure out how to properly import the framework into my project. I selected all of the files in the "Classes" folder (JSON.h, NSObject+JSON.h, etc.) that comes in the download, dragged them into the main area of my project, and added #import <JSON/JSON.h> to my ViewController's .h and .m files, and I get a No such file or directory error for JSON/JSON.h
What am I doing incorrectly here?
If you’ve placed the files under the Classes group and haven’t taken any further action, they’re at the root of your project directory. As such, import it as
#import "JSON.h"
I think you're indicating that you're importing JSON.h from the JSON folder, and it sounds from your description you don't have those in a folder...
i dont know what to do. I cannot add any .H file to Target in my projects. I tried add it from Add FIle, from drag and drop then info file and check target. Its greyed. when i try to add new file and choose H a cannot check to add it to target. whats is wrong?
Headers are not compiled, so they don't get added to the target.
Look at all the headers currently in your project like your XxxxxAppDelegate.h, you'll see it's not added to the target either.
the header files are not compiled into the project, only the source files and frameworks. The header files are only there to tell the compiler what it can expect in regards to sending messages to objects
I'm referencing a static library.
I've dragged the library project into my app project and reference it relatively.
The .a file from the library is linked into my app target.
I've added a reference to the librarys .h files' folder via Header Search Paths in the app project.
Then I add an import in my apps .pch file to a particular .h file from the library.
I build and get this error:
some.h: No such file or directory
The project is given info on where to find .h files for the library. Why can't it see them?
Try with
#import <some.h>
instead of
#import "some.h"
I don't think so. I just got one set up today piecing it together from the links below. I didn't include any .h files in search paths. In fact the one tutorial told me to remove any existing search paths (but I had to add them back for another library). Hope this gets you on the right track.
