Objective - C, Do i need to learn C

You don't have to learn C first, but learning Objective-C will be learning C plus some. This gets debated fairly frequently here, with no real consensus. If you have use for C outside of Objective-C, learn it separately so you know what's what. If not, and your only goal is Mac/iOS development, probably dive into Objective-C. Steve Kochan's Programming Objective-C 2.0 will cover what you need of C, so that might be a good place to start "from scratch".

Balamw said almost what I was going to say and I did not like the Stephen Kochan's book. For me it was dry, boring and wordy. I took a step back to learn C using this book which I liked http://www.apress.com/9781430218098 and this forum was a big help.

I even then took a class in Pascal which was another step back but a good thing. Learning from a book and then a teacher is a very different thing. The interaction was important for me.

Today was the last class and next Monday the Final!

Objective C is a superset of plain ANSI C. If you don't learn a fair amount of C, you haven't really learned Objective C, only a tiny part of it, and you won't understand how Objective C really works.

 

You don't need it to the point where you would be a competent C programmer, but you need some idea what it does. Some of the syntax of Objective C is very obscure to someone learning Objective C - until you realise that it's really C and then it becomes obvious.

You'll need to know about the basic types, pointers (very important), and you'll need C if you do any real maths.

 

It will also depend on your computer background. Do you know any other language: Java, PHP, Python ?
If not, you should try with a quick intro with C with online tutorials or books. As gnasher729 said, it's really important to understand what a pointer is.
For my part, I started with "Learn C on the Mac" (Mark) then switched to "Programming in Objective-C 2.0" (Kochan) and "Cocoa programming for Mac OS X" (Hillegass). The latter is a must.
