I was diagnosed with ADD as a kid. It turns out I was just bored. There are only 2 reasons for jumping around like this. Either you aren't that interested or you hit a knowledge roadblock.

The knowledge roadblock is probably the easier of the two to overcome. Join a local users group. My learning was highly stunted until I had people around me that could answer my (frequently dumb) questions face to face. Sites like stack overflow are great but they are no substitute for someone who can see the look on your face that you aren't getting it and change course accordingly.

Is building iOS apps something you really really really want to do or something that would be cool to know? Learning new things usually starts by sucking pretty hard. When the interest level dips below the difficulty level it is easy to move on to the next thing. If your interest level isn't really high to start it is going to be easy to jump from thing to thing.

A general productivity tip is have a clear objective, a fixed time and write it down in a place where you are going to see it. Attach a reward to getting it done and a penalty for failing to complete the task. Finally have someone to hold you accountable. When the pain of not getting it done is worse than the pain of doing it you will get it done.
