Copying Xcode samples

Whenever a new version of the iOS SDK is released, one of the first things I do is copy all the sample code released with that version to it’s own directory. This allows me to browse the samples more easily and open them all from a common location without having to open them one-by-one. Here is how we do that:

1. Open Xcode preferences and choose the Documentation tab. Pick the new library and show information on it (the arrow in the lower left corner opens the info pane). Click the link for the Installed Location to open Finder to that location.

2. The file that stores the documentation for this iOS version is a docset. The one we want should be highlighted. Right-click and choose “Show Package Contents”.

Show Package Contents

3. Browse to Contents/Resources/Documents/samplecode inside the package. This is where all the code and html for help is located. Now we just need to get the code out of the folders.

Contents/Resources/Documents/samplecode

4. Search at that location for filenames containing zip. That will show you just the zip files under that directory. Then you can select all, copy to a location you choose, I use a folder under my documents directory, and then extract the zip files (use Command-O to open them with all the files selected in the new folder). Now you should have a folder tree with all the sample code there ready for you to browse. Happy coding!

Adding jQuery to an iPhone project in XCode

You might think that if you add the jquery js file to your project, you can build and reference it from html you load into a UIWebView. That’s what I thought too. Here are the steps you need to take.

1. Add the jquery file to resources. Drag the file in, right-click and choose to add an existing file. Whatever you are comfortable with.

2. The file will be automatically added as source code. In Xcode under Targets, expand the target you are working on and you’ll find two groups, “Copy Bundle Resources” and “Compile Resources”.

3. Drag the file from the “Compile Sources” group

to the “Copy Bundle Resources” group.

This tells Xcode to package the file up and include it with your app as a resource instead of compiling it.

4. Include the reference to jQuery in your HTML.

html = [NSString stringWithFormat:@"<html><head><script type='text/javascript' src='jquery-1.4.2.min.js'></script></head><body>%@</body></html>", body];

5. Set the baseURL using the path to your jQuery file.

[myWebView loadHTMLString:html baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@”jquery-1.4.2.min.js” ofType:nil]]];

That’s it. You can now make jQuery calls in your code.
