> Obj-C is only dynamically typed > swizzling happens only once at compile time. Objective-C is a dynamic language in every sense of the term. As examples, at runtime, you can: - change an existing class' superclass
- swizzle methods
- create a class ex nihilo (though it'd be a better idea to inherit from NSObject)
- give that class (or even an existing one) methods, ivars, and properties .. and much more Visit the runtime reference[1] and jump into a running Objective-C app with GDB or F-Script. It's a lot of fun. [1] https://developer.apple.com/library/mac/#documentation/Cocoa... |
