// JSLint 에서 요구하는 변수 선언 // 잘못된 변수 선언 foo = 'bar'; // 올바른 변수선언 var foo; foo = 'bar';!=,== 보다는 !==, === 를 사용하라고 요구한다.

So
you have a killer idea for an iPhone app, but when you describe it to
people they just don’t get it. Maybe you have a client that is a visual
thinker and needs you to draw it out for him. That’s when wireframes,
mockups and stencils can be your saving grace.
There are many different types of tools available to developers, from low-tech stencil kits to high-tech collaborative software. So I’ve rounded up a few of the more popular ones people are using specifically for iPhone development. It’s far from being the definitive list, but it’s definitely a good place to start.
Notepod is a notepad shaped like an iPhone. Each notepod is 100 pages
of 60 x 110mm double sided paper. The front has 52mm x 77mm blank space
(the iPhone screen), the back is a 6mm grid.
The iPhone ui stencil kit is a stainless steel, laser cut stencil kit
for drawing quick mock-ups and wireframes for iPhone apps. It also comes
with a Zebra mechanical pencil.
The iPhone Sketchpad works precisely with the iPhone Stencil Kit, with
one phone silhouette on the front side and three on the back.
The App Sketchbook has 50 Double-sided, perforated pages each with 3
actual sized iPhone templates. Each page also has has 20px ruler
markings and a ruled section for notes.
A collection of vector iPhone UI elements for Fireworks CS3 and CS4.
Most iPhone screen elements, sensible layer sets all contained within one PSD file.
Graffletopia’s stencil kit for Omnigraffle.
It is for quick sketching of iPhone ideas. Use the outline for
printouts so you can hand sketch as well. The symbols are meant as a
check list for included features in your app development.
MockApp is a set of iPhone ui templates and library files put together for use in Powerpoint or Keynote.
This is a plug-in to browser Mozilla FireFox for prototyping interface
of iPhone applications for creating an iPhone mock-up. Currently Alpha –
not compatible with FF 3.55.
Pencil is a free and opensource tool for making diagrams and GUI
prototyping. Pencil runs on the Mozilla Gecko engine, turning the
Firefox browser into a sketching tool with just a 400-kilobyte
installation package.
This plug-in combines Fireworks with some jQuery and PHP to give you a
prototype you can not only view, but interact with, directly on your
iPhone, just as if it’s a live app.
Liveview is an iPhone app that consists of two parts: the ScreenCaster
and the Application itself. ScreenCaster launches a simple iPhone skin
on your Mac. From the same network, launch the LiveView app in your
iPhone. Whatever the ScreenCaster is highlighting is now seen in the
LiveView App. It also interprets touches as mouse clicks, turning it
into a two way interactive prototype.
Mockingbird is a web based mockup/wireframe tool built using the
Cappucino framework, so there’s no flash to wrestle with. While you
can’t actually design your mockups from an iPhone (who’d want to?), the
tool does have some very handy features. You can drag elements onto the
screen, create multiple pages, link to other pages and share directly
from the web.
Pidoco is a web-based tool that lets you create clickable wireframes
via drag & drop ui and then collaborate with remote users on each
project. The tool also includes iPhone stencils.
iPhone mockup is a web based tool that is currently in Alpha release
only. You can design your mockup as a hand sketch or illustration, and
mockups can contain user-uploaded images and user-entered text. Your
mockups will be accessible via url so they are unsecured.
The developer makes this perfectly clear and warns that he could discontinue hosting mockups at anytime, thereby deleting any work. That makes this a handy tool for quick and dirty mockups you want to print or share with someone on the fly, but not for much more.
Protoshare is a collaborative, web-based prototyping tool that helps
teams visualize requirements for interactive projects and work together
in real-time. It has an iPhone component that can be seen here.
With iPlotz you can create clickable, navigable wireframes to create
the experience of a real website or software application. You can also
invite others to comment on the designs, and once ready, you can then
manage the tasks for developers and designers to build the project.
CogTool is a general purpose UI prototyping tool simply using a
storyboard of your design idea with sketches, images or on a canvas.
Demonstrate tasks on that storyboard, then press a button to produce a
valid cognitive model predicting how long it will take a skilled user to
complete those tasks.
Balsamiq mockups is desktop software that is designed to help teams or
clients collaborate on wireframes and mockups. There are iPhone specific
controls included.
OmniGraffle is award winning diagraming mockup or graphic design software. Combined with Graffletopia’s iPhone stencil kit, this software is a great addition to any app developers toolbox.
Justinmind prototyper allows you to create fully functional wireframes
for mobile applications and generate your HTML high-fidelity wireframes.
iRise for iPhones gives developers a way to quickly prototype the look,
feel and behavior of Apple iPhone applications through pre-defined
visualization widgets and templates that can be quickly assembled into a
high definition mobile applications.
