For a developer accustomed to other languages, the following features in Objective-C may seem unusual:
-
Message passing syntax: instead of calling methods with a dot, square brackets are used, for example
[object method]. -
Dynamic typing and early binding: many operations are performed at runtime, which differs from static typing in C++ or Java.
-
Use of pointers and memory management: although ARC (Automatic Reference Counting) exists, developers need to understand pointers and references.
-
Categories: the ability to add methods to existing classes without inheritance.
-
Protocols: similar to interfaces, but can contain optional methods.
-
Lack of namespace: all classes are in a global namespace, requiring the use of prefixes in class names.
Example of calling a method in Objective-C:
NSString *greeting = [NSString stringWithFormat:@"Hello, %@!", @"World"];
This style differs from the conventional method calls in other languages, which may require some getting used to.
