title: Objective-C Challenges/Examples
body: <p>I'm currently learning objective-c. I have heard (and experienced) that the best way to learn is doing it yourself, trying to reach a goal. For example, trying to code a simple app and having trouble completing it, then persevering and accomplishing your goal, meanwhile learning a lot. Hopefully you know what I mean. Well it's hard for me to come up with challenging programs/applications to code. I'm wondering if there is somewhere that someone has listed a few challenges (i.e. "try and make the program do this")  or examples like at the end of each chapter of the book, "Programming in Objective-C, 4th edition" or the book "Objective-C for Absolute Beginners". Does anybody know of a website that has a few of these or does anybody want to help me by challenging me? (I'm a super beginner so not to challenging.) Thanks for your time and answers. :D</p>
