What is good literature on Objective-C?

Question

Objective-C

Please tell me literature practice, theory and logic of thinking in the literature on Objective-C.

Answer 1

at first I didn’t read books on objective c, a couple of articles were enough for me to enter and then what I needed, I googled or looked at the documentation from apple
later I started reading two books, but after a certain number of pages I realized that there was nothing new for myself opened and abandoned:
using objective-c, you need to read a book with an orange on the cover ( www.ozon.ru/context/detail/id/21462201/) - this one comes out for each sdk, i.e. you need the same one, but only for SDK 7.0/7.1
on Core Data there is still a good one: www.amazon.com/Pro-Core-Data-Second-Edition/dp/143...
other books that I found, looked at reviews in network and did not even start reading
