i want to add a image to the iphone application Targets-Copy Bundle Resource folder by using code,can make it?any suggestion
Do you want to add images to your built application, so they're available at runtime? In this case, just drag them to your Project tree and make sure your target is checked in the Add dialog. If they're already in your project, but aren't currently in the Copy Bundle Resources, you can drag them there from the file tree.

Okay, I am a noob. It must be simple but I stuck here.
I do rigth-click and choose 'select file'.
After I choose the file the dialogue appears:
I want to keep my icons not in the root directory. But I can't figure out how to do this. I tried different ways, even create project from scratch...
Please help.
When you bring image assets into Xcode they will all be in your application bundle's root directory at run time.
It appears that you've added a file named "icon#2x.png" to your project at one time already. Go to the project's summary page in Xcode click Build Phases and then expand the section titled Copy Bundle Resources. There you'll find the reference to the resources that will be copied to your bundle at run time.
More on bundle structures here:
https://developer.apple.com/library/mac/#documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html
Anyway, the way I've done this in the past is to:
Remove the existing image duplicate from Xcode and from the folder structure in Finder.
Add a new folder in Finder call it "/AppIcons" (or whatever).
Copy all the app icons to that folder in Finder.
Drag the "/AppIcon" folder into your XCode project. I typically put images in an "/Images" subdirectory in the Xcode project. Again you can put it wherever you'd like.
In Xcode on the project summary panel, add your app icons from the folder "/AppIcons" by dragging / dropping or by right clicking and adding them as separate files.
Alternatively in the past when I've had problems with this sometimes Xcode will copy the app icons to the root project directory. If that happens, I make sure that I have the "/AppIcons" folder structure on disc (in Finder) and in my Xcode project. I add the app icons to the project, then move them to /AppIcons in Finder, and re-reference them all over again.
Your Copy Bundle Resources should then have the proper file reference. Note that my apps icons go in "/Images/AppIcons"
Good luck!
I would add the image files to your project with the name icon#2x.png. To do this right click where you want to add the files in xcode and click add file/s. Then search for your image and add them using the dialogue that pops up. - there is a check box so that you can either copy them to the projects destination folder which will copy them into you project folder or leave it unchecked (inadvisable) which would reference it's current location on your HDD. Make sure the file doesn't already exist in the project before doing this!
EDIT:
Sorry I forgot to mention then drag and drop the file from within xcode onto the image location box.
In XCode 4 (I'm using 4.6.2) you will get this confusing message if you've just moved the target's info.plist file, but not corrected the location at the top of the summary panel. Fix this and the icons will reappear, assuming they are added to the project, or if not you should now be able to drag them in without xcode insisting on making extra copies.
This tends to happen when you're starting a project and sorting out the mess of default file locations that xcode gives you. I like my project structure to be 99% the same as the file system structure.
This is an easy fix. If the image you want as your App Icon resides outside of the root of your project, when you get that dialog just click "Yes", and then click delete on the newly created file in the root, and "Move to Trash".
The reference is still there and works without a hitch, since the file will still be in the root at runtime
I made a generic app, and from that app, I use different images to make different apps (same app, different images).
My idea until now has been every time I was generating a new app, I copied the code and changed the images (and sometimes some lines of code). But every time I change something in the main app, I have to change it in all the sub-apps.
I've been thinking about using target for this (every time I create a new one, I use a new target with a new folder images linked to it), but I'm not sure about this as I never worked with targets before.
Is this the best approach?
And if it is, how is the best way of doing it? I created a new target inside my project, but it creates a whole new project inside of it, with its owns classes.
For your case, using multiple targets is a good solution. For each target you'll include all sources, and only the images used by that target (images can have the same name, just put them in separate folders).
On Xcode 4, you'd need to follow these steps:
Go to Project settings, right click on your main app target and choose 'Duplicate'. This will already include same sources from the main app.
Unlink all images that you don't need in your new target:
select all images that you want to unlink, and in the utilities panel (usually placed on the right), in the 'File Inspector' section, uncheck your new target
Create a new folder in which you place the images for your new target/app, and when you import them in the project, choose to link only with your new target.
When you duplicate your target, it will also automatically create a new info.plist for your new app. You'll need to change the bundle id, and any other options that you wish.
Another option would be to make the main project as a static library, and in all other projects include the main project, and link the target. Won't get into this, since the targets solution seems better for your case, for only changing the images.
I wish to add a link showing howto - in support of the above answer. Hope it will be helpful to others also.
iOS Mobile Development: Using Xcode Targets to Reuse the Code
http://www.itexico.com/blog/bid/99497/iOS-Mobile-Development-Using-Xcode-Targets-to-Reuse-the-Code
Trying to change the name of the app from the development name to the production name, I renamed the target as a first stab. The PNGs in the app disappeared. I then changed the target name back to the original name and re-built, but now the PNGs are still missing.
I'm looking at step-by-step guides on project/app name changing, but I don't want to proceed until I'm unable to undo whatever this did.
Does anyone know why the images would now be missing? Even after I changed the name back?
I'm assuming there is some path based on the target name and that changing the target name triggered other changes not reversed by simply changing the target again?
Many thanks
why not just use Product Name under Target -> Build Options. So you don't have to change the target name! :)
Type in the name of your project in the finder, and double click on the project folder. Inside that folder (it may be in a folder inside that folder, like resources or something but on my computer its all in the project folder) look for .png images. These images are the images that are in your project. Delete every image inside here, or just move it somewhere else. If your app has the .png files inside the project folder, but the files are in your resources folder, you won't be able to put in the same image in your resources folder because your project (your app) says its already there, even though its just sitting there and your not using it...
So delete all the .pngs inside your project folder, then open up the app with xcode and drag the image files you need into the resources folder. Hope this helped.
Each file in a project can be included in a target, when you changed the target name, its possible that png files lost association to the target. right click on the folder which has the png files, and click on get info, there you will be able to select which targets this folder is included in, mark the check box for your intended target, and the files will be included again in your target.
I am creating a game using cocos2d.
Now what I want is I need to insert the image from Photo Library to my application. Can you please tell how can we access Photo Library through cocos2d?
Thanks in ADVANCE...
You should be able to access the users Photo Library in the normal fashion. As far as actually using the selected photo, is a different question. ;-)
Not sure if this is what you mean but...
To use an image in your application you put the image file in your resources folder in xcode. Then you can reference it by name to use it for your sprites or anything else that will use a file. This goes for other types of files that your application will use too (like data files, plists, etc).
If you put an icon file in your resources folder in xcode and name it icon.png then that will be the icon that will appear for the user to select to run your application on the iphone/ipod/ipad.
Same goes if you put another file in the resources folder and name it default.png then it will show up as the splash screen that appears while your application is being loaded.
Note: If you are working with a template it will probably already have canned files with these names. Just remove them from the resource folder in xcode and add the new ones. To add the files to your project, drag them into the resource folder within xcode and select the check box for: "Copy items into destination group's folder (if needed)", as well as, make sure in add targets section only the check box for your application name is checked and the radio button "Recursively create groups for any added folders" is selected. This will copy the file(s) into your project directory and they will also appear in the resources folder in xcode. You can then click on them in xcode to see that they are correct.
My problem is something that should be so simple it is mind boggling. When I change the look (in PhotoShop) of an image file that is being stored in my app bundle. My method for replacing the old image in the bundle with the new one is this:
1) remove the old image from the app bundle (choosing to also move to trash)
2) drag the new image into my file hierarchy in xcode (choosing to copy to app directory)
when I do this, the app cannot find the image no matter what I do. The new images have the same name as the old images but none of the image loading methods (imageNamed, imageWithContentsOfFile, nibs) work. (Although I believe nibs also load with imageNamed, i'm not sure).
Is there something that I am missing here? I feel like it should be a relatively simple process but I am having all kinds of trouble. I also make sure to delete the app off of the target device and clean all targets before rebuilding and running after changing the image files just in case.
Any help would be appreciated.
Thanks
Your problem is probably that the image is not copied to the target. In xcode groups & file pane, fine the node for targets, expand your app target and you'll see Copy Bundle resources expand it and you'll see all the files copied to the default resource bundle when you deploy your app to the sim/device. Only the resources found there will be available to your app. If you don't see your image there you can just drag it there and everything will work.
Now, in order to understand why this might happened we need to look at the different options for adding files to xcode.
When you're adding a file to xcode you are presented with a dialog that includes a few interesting and sometimes overlooked option.
The first - Should the file be copied to the project folder, or should it just point to the file original location. The safest way will be to always copy the files to the project's path. However for images (such in your case) I do it differently. I maintain a separate graphics folder for every app, I save images there (both sources, and final png). When I add an image I do not copy it to the project folder, rather xcode just points to its location. That way I can just edit the image in photoshop, do a rebuild, and the updated image will show up on the phone. Whats important to understand that the directory structure of files you include in the project have almost no meaning, files that appear in the Copy Bundle Resources for the target will always be copied to a single (and flat) bundle/"directory" on the phone. The only exception for this is if you actually add directories to xcode (Personally I recommend against it).
The second option when adding files, is to which targets to add the file. This is the list with checkboxes on the bottom, if when you added the image, your app target wasn't checked the file won't be included in the target Copy bundle resource, and won't be available for the phone.
A few caveats - When using references to files in other location, that location is relative to the project's path, so it's a good idea to keep all the files in directories below the project's root directory. That way you can still copy the entire project to a different location and it will still work.
Great advice above: I thought I would add more for future searches on this topic:
I was adding and removing images to the project just like above:
Remove the old image from the app bundle (choosing to also move to trash).
Drag the new image into my file hierarchy in xcode (choosing to copy to app directory).
However when I tried to drag the new image with the same name to my file hierarchy in xcode I was getting an error that this was not allowed.
Turns out when I was removing the old image Xcode was removing it from the project file hierarchy but the actual file wasnt being removed from the project's root directory.
I solved my problem by removing the image from the project's root directory and added the image again!
Do you put your images in a custom sub-folder? If you just drag in images into the Xcode project tree, if you copy them, the images will be copied to the root of the project directory, instead of the "Images" or other folder you might have set up.
Note that you can right-click on the image in your bundle, select "Get Info..." and reset its location, if it has been moved or copied to a folder you didn't expect.
