http://oleb.net/wordpress/wp-content/media/apple-symbols-font-glyphs-table.png
how can I access these icons, export them from MAC system to png files or dynamically access them in cocoa codes ?
Welcome any commnent.
Thank
interdev

Before doing this, take Brad Larson's warning into account...
You'll need an image editor, like Photoshop or The Gimp that can handle glyph fonts.
Once you have that, you can use the Apple Symbols glyphs in a text field and save it as a transparent PNG, which you can then resize and add to your project as an icon.

Can SVG images be used?

For some reason, I can't get SVG images to show up on my phone, only the simulator. Is this bug / feature that is in progress / expected? I can't find any documentation on file formats in the guide.
Don't know if this affects it, but I'm using API.AI's Actions on Google tab to create the carousel.
Thanks in advance!
The phone doesn't support SVG, and that's the expected behavior.
You can use JPG, PNG or even GIF with animations.
I agree that this should be available in the documentation.

Colors not matching in Illustrator and iPhone

I am making an icon with RGB color 186 186 186 in illustrator, and I have set the background color to the same. However, they appear to be different shades when I test the app!
Is there something I have to to do with the color profile?
I have tried this link:
How can I make colors in Adobe Illustrator line up more closely with colors on the iPhone 4?
But it does not help.
Thanks in advance.
I've had similar issues and what I use at least for Photoshop is I use something like Developer Color Picker (Free: http://www.panic.com/~wade/picker/) or Colors (Free: http://mattpatenaude.com/) But here are some other possible issues:
In illustrator check the color mode you are using here: File > Document Color Mode
If you are changing the image to jpg, png, etc. check your default color profiles I know there is an option to check ICC Profile while saving for web in Illustrator.
If you're having issues like this across the Adobe suite in Adobe Creative Suite 2, you can use Bridge to synchronize your color settings across all of Adobe apps.
Hope this helps.

Install Smiley font for iOS

I Need to use my own smiley icons (like emoji) in my textfield and all around the project. Is there any way to install the fonts in iOS. Please suggest me for the right way...
I got that there is no solution for the installation. I created manual keyboard using scrollview and buttons.
Should be easy, as long as you know which glyphe is which smiley:
Have a look at Custom Fonts in iOS 4 at beefyapps.com.
EDIT
The Emoji Icons are a stored in the private use area of unicode. They won't look any good on a different device than an iPhone/iPad, this is Apple specific.
The app is just to enable the keyboard. You can do it yourself: Making An Emoji Enabeling App.
Have a look at The truth about iPhone Emoji, which sheds some light on the whole topic.

Iphone tab bar icon

I should probably be asking this on some art website, but in my iPhone app I am trying to make a center button on my tab like the one Daily booth has, but mine is coming out fuzzy. Does anyone know how to make then clean and crisp? I used illustrator to create and save the icon as a png.
Try setting the image size to 30x30 and remember to only use black and transparency. You can make this bigger for the retina display.
Also, are you saving the image as grayscale?
If you're struggling to make them yourself, why not try glyphish.com?
I really like Paint.NET on Windows for image editing, mostly because it is free.
I noticed somebody had created an Effect for Paint.NET to create tab bar icons. I haven't tried it myself, so can't vouch for it in any way:

Can i use a jpeg image for launching Screen

i was currently in to an app development and i have added a launcher screen in JPEG format which is displayed both in simulator and device .. but does it create any problem with apple approval guidelines ?
Update for iOS 8+: you can now use XIB-based launch assets, which is by far the best approach to reduce file size and re-use the same assets for multiple screens sizes. Also, since XIBs support JPG assets, you can always embed JPGs onto XIB files now too!
The Apple documentation pre iOS 8 (now removed), explicitly stated that only PNG is allowed for the launch image:
App Launch (Default) Images
Every app must provide at least one launch image. This image is
typically in a file named Default.png that displays your app’s initial
screen in a portrait orientation. However, you can also provide other
launch images to be used under different launch conditions. All launch
images must be PNG files and must reside in the top level of your
app’s bundle directory. (Avoid using interlaced PNGs.)
I can't speak to how accurate this document is, but it seems they are pretty specific on this point.
My advice: use 8-bit PNG's, and if your files are getting to big, simply don't include the #2x versions for the retina iPad. The 1x version upscales reasonably well on the retina iPad, and better than bloating your app by 5MB+
Yes ofcourse you can use JPEG image in Launch screen or anywhere in project.NO it absolutely does not create any problems in approval process of Apple.So go ahead and code!
Use a png if you can; not only is png artwork better visually, but iOS is optimised for png files.
While it is true Apple won't reject your app for using a jpeg, your users might.
NO you should not use jpgs
Here are apple recomendations
Note: For all images and icons, the PNG format is recommended.
The standard bit depth for icons and images is 24 bits (8 bits each for red, green, and blue), plus an 8-bit alpha channel.
You do not need to constrain your palette to web-safe colors. Although you can use alpha transparency in the icons you create for navigation bars, toolbars, and tab bars, do not use it in application icons.
You can only use PNG files for the launch images. Here is the proof.
Yes , you can choose any one from JPEG/PNG.There is no guidelines from apple to choose type of image.
For more information you can follow apple launch image guidelines.
but I assume that PNGs are more preferable because Apple seems to use PNGs virtually everywhere in iPhone OS.
