Start with Paul Hegarty's iOS class on iTunes U, it's free and it's terrific. Do all the assignments (if you get stuck you can find other people who have done them and see what they did but I really recommend doing it yourself.) Sign up for NSScreencast.com and watch 1 or 2 a day, taking notes. Go read as much Ray Wenderlich stuff as you can that's not dated (some of the stuff on his site's kinda old, but no matter.) Then build an app and put it in the app store, it can be lame but you have built so many practice ones it's good to actually get something in the App Store. Go read some stuff at objc.io, some stack overflow, whatever.
You are now an entry-level iOS developer. I just saved you $12,000 and you don't have to beg strangers on the internet for donations. Seriously, $12,000? I guess it's true: the best way to get rich in a gold rush/bubble is selling pickaxes. There are enough great resources out there that you are silly if you do this.
