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 ri开发者_如何学编程ght 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:

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.
