The language used to code apps for iOS is Objective C. Although Objective C is based on C, syntax of objective C is very different.
Apps for the iPhone/iPad/iPod Touch are developed using the iOS SDK provided by Apple.
The SDK comes along with a few more applications.
The first one is XCode, it is an IDE (Integrated Development Environment) like NetBeans or Eclipse. Along with iOS development you can also develop apps for Mac OS using XCode
The other application that comes bundled along with the SDK is Interface Builder. This is something like a What-you-see-is-what-you-get (WYSIWYG) tool to create interfaces for iOS and Mac OS.
Then there is the iPhone simulator which as you guessed it is a simulator for the iPhone on your Mac. When you build a project (compile) there is an option to either run it in the simulator or the actual device.
