Luckily for me, almost all of my apps are a combination of Ruby on Rails3 web apps and iOS apps. This makes it easy to see all of the reports for a bug in one place for both the Rails and iOS errors.

Hopefully Android support is on the way for Hoptoad as well.

“I happened to be auditing the Stanford iPhone Programming course,” says Kaplan, “and one of the guest speakers discussed how he went about creating his user interface designs. Paper was one option he mentioned. Almost instantly the notebook idea light bulb went off. Other options of various computer programs were mentioned, but it always got back to paper and pencil. Subsequently, I did my own online survey that revealed designers prefer paper 95% of the time.” – theAppleBlog

The sketchbook contains 100 grid pages with an iPhone designed to scale on it. Each page has it’s own header that allows you to put in the name of the app and the name of the screen. The pages are big. There is ton of free space for taking side notes during group sessions and team meetings. The notebook itself is paperback, plastic spiral bound, and can be ordered from Amazon.com for $14.99.

Q & A with Dean Kaplan

1. What are your plans for the future of the sketchbook?
   “There will be a huge exciting announcement concerning the book next week. Stay tuned.”
2. Do you plan on creating a Stencil Kit similar to The Design Commission’s one? Or perhaps making the iPhone on the pages slightly larger to be more compatible with the Stencil Kit?
   “LOL. Are you spying on me? As for size….I guess you are saying size matters. And I’m listening to feedback and it is likely that you “might” see a version that is 1.5X actual very soon. (DC’s stencil is smaller then 1.5x and I don’t think its very useable. )”
3. Have you considered perforated pages for easier tear-off?
   “I’ve heard the perforated request once before. Not likely on that one. As one reviewer told me he like to tear the pages right out of the book and paste them on the frig.)”
4. A folder built-in either the front or back cover for keeping materials given from other team members or clients together?
   “I love that idea. It crossed my mind a few months ago. Likely in a future UBER Sketch Book.”

The Good

• Keeps all your apps and screens together instead of having multiple pieces of paper that can get easily lost.
• Grid pages are very handy for going from sketching to computer rendering.
• To scale iPhone keeps you in the restriction of the small space while also reminding you to beware of your font sizes.
• Cheap. $15! If you’re just getting into iPhone app design, this can definitely help you on your way in keeping your ideas organized.

The Bad

• Not compatible with The Design Commission has created an iPhone Stencil Kit. Different companies, Can’t really complain.
• The to scale iPhone on the page is also a bit harder to draw stuff inside it.
• Since there’s no stencil, you need to keep in mind what you get with the SDK and what needs to be custom made. Thought it’s not that big of a deal.

Final Thoughts

Right now, I’m using a Moleskine Squared Notebook to do my sketches for iPhone apps and other web related work. It’s much smaller than the iPhone sketchbook, but it does allow me to put other thoughts and ideas inside. For what the purpose it was designed for, the iPhone sketchbook delivers and does so very well. Compatibility with the Stencil Kit would definitely put it over the top. The last things that I would like included in the sketchbook, would be a small folder built in and perforated pages. Those are some very small personal requests though.

Special Note: If you order between September 10th and October 10th you’ll be entered to win ONE free ticket to the Voices That Matter iPhone Developers Conference 2009.

1. iphone-exif

   An Exif Tag library editor that enables direct viewing and editing of EXIF Meta Data tags in Jpeg files on the iPhone. The most obvious use is to manage Geo location tags into the image. However, it is also possible to edit any of the Exif tags or add your own that are not in the spec.
   This is really useful for image uploads from the phone for sites like Picasa and Flickr.

2. json-framework

   This framework implements a strict JSON parser and generator in Objective-C. You get free XML parsing support from the official iPhone SDK, but not JSON support. This is a way to add it.

3. openssl framework

   It is specifically intended for use in building secure iPhone
   applications alongside SQLCipher (https://www.zetetic.net/software/sqlcipher).

4. iphone-smtp

   This code implements a quick class for sending one off messages via SMTP on the iPhone.

5. cocos2d

   framework for building 2D games, demos, and other graphical/interactive applications. It is based on the cocos2d design: it uses the same API, but instead of using python it uses objective-c.

The guys over at the Design Commission [@designcom on Twitter] have gone and made an iPhone Stencil Kit as a follow up to their popular Website Stencil Kit. Initially they had 1,000 stencils made for sale, but due to popular demand, have since made many many more. I received mine on Monday and have started using it for an iPhone App that I am currently developing.

The details:

The kit costs $16.95 + shipping&handling [Domestic shipping is $4.95 and international is $15] and includes:

• One iPhone UI Stencil
• Zebra mechanical pencil
• 2 Design Commission stickers
• Downloadable .PDF letter-sized paper template

Using the kit

The kit is really created with the intended use of the printable PDF templates. It doesn’t have a full iPhone body stencil to draw your iPhone on a separate paper. It does do a decent job at half-skeleton of one though. You’ll have to fill in some missing lines yourself. The notable missing seems to be status bar, the section with the wifi, 3G, and battery icon area, not being stenciled. The other small problem I ran into so far is that it’s made of stainless steel. I can’t see what’s under the stencil as I try to approximate the needed spacing between Tab Bar icons. Although, I do need to keep in mind that it’s made of stainless steel to be more durable than plastic and also that I’m making prototype designs to show clients, not finalized work.

Overall, the only real downside I can see, is that you really do have to use a mechanical pencil. The one provided by Design Commission, is a Zebra, which are extremely good. But, if you use a regular #2 pencil, you will likely run into some trouble on some of the smaller stencil bits, requiring you to constantly sharpen your pencil tip. Other than that, it’s a really great addition to any iPhone developer’s arsenal.

Now of course, this is all for paper prototyping. And if you have been following Stanford’s CS193P iPhone Programming class on iTunes, Steve Marmon discussed the importance of paper prototyping for iPhone App design in his lecture How to Build an iPhone App that Doesn’t Suck [iTunes link.]

If you prefer digital prototyping, Balsamiq has updated their software to include iPhone designing, and  in my previous post: 5 Free iPhone Resources, I have links to Omnigraffle, Adobe Fireworks, Photoshop, and Illustrator stencil kits.

Joe Hewitt's Three20 Project

With Apple’s WWDC currently going on and the upcoming 3.0 iPhone OS getting closer to release, there are tons of new developers jumping onto the platform. Whether you’re a new developer or have been developing for a while, here are some great free resources for designing and developing your iPhone Apps.

1. Google Objective-C Data APIs

   Google generously provides a large set of their APIs in Objective-C for both Mac and iPhone development. These APIs include:

   • Google Base
   • Analytics
     
   • Blogger
   • Book Search
   • Calendar
   • Code Search
   • Contacts
   • Documents List
   • Finance
   • Health
   • Picasa Web Albums
   • Spreadsheets
   • Webmaster Tools
   • YouTube

   Check out my previous post on How to add the Google APIs to your iPhone App project.

2. Joe Hewitt’s Three20 Project

   Joe Hewitt is the developer behind the popular Facebook iPhone App and the Mozilla Firefox plugin Firebug. He’s created a new projected called Three20, which is a collection of iPhone UI classes, like a photo viewer, and general utilities, like an HTTP disk cache. The project and instructions on getting it into your iPhone App project are hosted up on GitHub.

3. iPhone Photoshop PSDs

   It’s always a good idea to start with a design before you start developing your iPhone App. It’s also easier to show a potential client a PSD mock-up of the app before doing actual development even though Interface Builder makes it an easy process. Here are a few Photoshop PSDs to get you going.

   • Smashing Magazine’s iPhone PSD Vector Kit
   • teehan+lax’s iPhone GUI PSD
   • 320480′s iPhone Interface PSD
   • FreshBooks iPhone GUI PSD

   Note: If you are planning on using these for making an iPhone Apps website, make sure either you or your client has gone through Apple’s Available on the iPhone App Store logo license program to avoid any legal issues. This can be found in your Apple Developer Connection Program Portal’s Distribution -> App Store tab.

4. OmniGraffle Stencil Kits

   If you’re on a Mac and use Omni Group’s OmniGraffle for wireframing or mindmapping web design, you can do the same with iPhone apps.Here are 3 iPhone Stencil sets for OmniGraffle. Also, Yahoo!’s set can be found on the Yahoo! Developer site with stencils for many other things and also in makes them available in Photoshop PSD format.

   • Theresa Neil’s iPhone Wire Frames
   • Patrick Crowley’s Ultimate iPhone Stencil
   • Yahoo!’s Mobile – iPhone

5. Glyphish – iPhone Toolbar Icons

   The Glyphish designer has generously put out 80 free icons for use in your iPhone App’s toolbar. These are all free and licensed under Creative Commons.

3 Bonus Resources

1. Mercury Intermedia’s iPhone UI Vector Elements for Adobe Illustrator.

   Working in Illustrator instead of Photoshop? These free vector elements great for designing.

2. eddit’s 120 iPhone Toolbar Icons

   While this one isn’t free, it is a really good and worthwhile one. Eddie Wilson over at eddit has created 120 iPhone Toolbar Icons for sale at $69. If you want the vector format, it’ll cost you a pretty $189 for the PSDs.

3. Open Source iPhone Apps

• WordPress iPhone App
• FreshBooks iPhone App

Have I missed any others? Do you have any more free resources? Please feel free to share them in the comments!

Edit 6/23/09:

An additional Adobe Fireworks set of UI elements has been found thanks to Building43.

• Google Base
• Analytics – (Only available via SVN Trunk or manual download)
  
• Blogger
• Book Search
• Calendar
• Code Search

Step 1

The first step, is to head on over to the Google Code website for the Objective-C Client, download and extract the zip file source code. Alternatively, you can get the latest and greatest version via Subversion using:

 svn checkout http://gdata-objectivec-client.googlecode.com/svn/trunk/ gdata-objectivec-client-read-only

If you downloaded the zip file from the website, you’ll have version 1.7.0, and if you used the svn code you’ll have a -read-only folder.

Step 2

Open up the GData XCode Project from your downloaded folder as well as your iPhone App XCode project.

Step 3

Drag over the GData Sources Folder from the GData project to your iPhone App project and add it as reference [don't check the box for Copy items into destination group's folder (if needed).] You do not need to copy over all the files into your project. You can, but it’s not required.

This will add a ton of files to your project. You may delete the APIs you are not planning on using, but make sure that the files GDataXMLNode.m and GDataXMLNode.h in the Common/Optional/XMLSupport group are not removed from your project as they are required for iPhone builds.

Step 4

Open up the build settings for your iPhone App project. Located and set the following settings.

• Header Search Paths: /usr/include/libxml2
• Other Linker Flags: -lxml2

For the Debug build configuration only, add the Other C Flags setting so that the library’s debug-only code is included:

• Other C Flags: -DDEBUG=1

Step 5 (Optional for iPhone 3.0 Beta SDK)

If you downloaded the zip file version (1.7.0) of the API, you will also run into this error message when you attempt to first build your iPhone App project:

...Source/Networking/GDataHTTPFetcherLogging.m:224: error: 'NSTask' undeclared (first use in
...Source/Networking/GDataHTTPFetcherLogging.m:224: error: 'task' undeclared (first use in this
function)

Apple has removed the NSTask from the Foundations Framework in the iPhone 3.0 SDK. In order to fix this, simply open up the GDataDefines.h file, find the developer section and add:

#define  GDATA_SKIP_LOG_XMLFORMAT 1

Note: This fix is only needed if you downloaded version 1.7.0 of the GData Objective-C API and are using iPhone 3.0 Beta SDK. If you downloaded the latest Subversion read-only trunk of the code or are using iPhone 2.2.1 SDK, you do not need to do this.

Step 6

At this point, your iPhone XCode project should build successfully and you can begin using the Google APIs by simply importing the appropriate header files. ie.

#import "GDataAnalytics.h"

Step 7 (Optional if downloaded GData version 1.7.0 Zip file)

If you downloaded the zip file version (1.7.0) of the API, you will be missing the Analytics API. That has not yet been zipped up for the download. You may want to download those separately.
