Messed around a lot with the Three20 Framework and decided against it. Most of the things really feel like "reinventing the wheel" - opposed to enhancing UIKit. The documentation is also far away from being great. (020200)

Lessen learned: I spend hours, if not days, messing around with disappearing instance-variables, that I kept reusing. Or also a UIActivityIndictor that sometime won't hide, although it should (sometimes yes, sometimes no). The scope of this variables was defined local in the @implementation-section. After putting the vars into the @interface, and adding @property and @synthesize methods, all issues were solved. I think, it's got something to do with the lack if retain on my first approach.

This post at Stack Overflow really helped me, understanding the Responder-Chain vs. the View-Hirarchy. And why a UIVIewController can come in handy, if you want views / subview respond to events. (020200)

Memory Leaks! What a lovely topic. I found two threads, that tell about important finegranular differences, when dealing with objects in Cocoa. First one if about appending to NSString and NSMutableString without leaks. Second is about treating your RSSParser the right way. (020200)

Uhm, I suppose the UITableViewController does not have always advantages. For example, you will need a workaround for scrollToRowAtIndexPath:atScrollPosition:animated at the tableView. This isn't obvious and also not documentated. (020200)
