There are 2 problems with TouchOSC for this.
Each TouchOSC text field can only show 1 line of text, and each line is center justified
Depending on what you want to do there may be a better alternative. These would include an OSC controlled app that can do multiline text like Lemur, or just using QLab text cues to a Syphon surface and using NDISyphon on the mac to send to NDI monitor running on the ipad.
Or perhaps the teleprompter app I detailed in my previous post is actually the best solution.
If you give some more details of your project, i.e what text you want to display, how do you want to control it, and who are you displaying it for and why, then it will be easier to recommend the best solution.
You may also find these links useful:
which is a solution you could use with NDISyphon.

which has a lot of detail which isn't relevant to your project, but shows how to display text on iPads, using TouchOSC, Lemur and Open Stage Control.
