问题 I've been searching on how to resize the tab bar items on the "Tab Bar Controller," but obviously couldn't find anything.

So 4 items show up on the bottom and a "more" item that shows the other two items when clicked. My title for all my items are short, so I want to squeeze 6 of them right below without the "more" and the only way to do that is to

问题 My application got SIGABRT throwing error message: "Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: ...

问题 I have a table view set up with a search bar. Everything works great: when I type text into the search bar, the results update in the table view based on my search text. The problem I'm having is in determining what the ID of the table cell is to pass that along when I'm going to my detail view. To clarify: the cells in the table view are usually generated from a SQLite3 database and ordered by their name. So if I have 4 cells: (Cabernet Cortis, Cabernet Franc, Cabernet Sauvignon and Ruby

问题 I am a total beginner with Xcode and Objective C, but I have some experience with OOP in C++. I bought this book. I read about how to make a simple app, and skimmed the rest of the book.

Writing a pretty printer for these types is highly non-trivial due to their complexity. (E.g., std::string is remarkably complex in libc++.) How in the world are other
