The document compares C# and Objective-C, demonstrating how to define and call methods in Objective-C. It shows an example of inserting an object into an array at a specific index. It also discusses using nested messages to avoid temporary variables, defining and accessing properties, and differences between pointer syntax and namespaces for classes like NSxxx and CGxxxx in Objective-C versus C#.
![Nested messages
To avoid declaring numerous local variables to store temporary
results, Objective-C lets you nest messages.
C# C#
myAppObject.theArray() myAppObject.objectToInsert()
return A return B
[A insertObject:B atIndex:0]
object method parameter parameter](https://image.slidesharecdn.com/objectivecprimer-111031235929-phpapp01/85/Objective-C-Primer-with-ref-to-C-8-320.jpg)
Objective C Primer (with ref to C#)
- 1. C# => Objective C primer Nov 2011
- 2. Demonstrate example for using header file: method definition
- 4. Object type Demonstrate example for using adhoc object
- 5. Method & Messaging C# void InsertObject(object anObject, int index)
- 6. Method & Messaging Objective-C vs C# + static (class method) - (normal public instance method)
- 8. Nested messages To avoid declaring numerous local variables to store temporary results, Objective-C lets you nest messages. C# C# myAppObject.theArray() myAppObject.objectToInsert() return A return B [A insertObject:B atIndex:0] object method parameter parameter
- 9. Use accessor methods (Properties) using dot
- 10. Properties Declare – in .h file Define – in .m file
- 11. Pointer: *
- 12. NSxxx, CGxxxx NextStep CoreGraphics
- 13. cocos2D objects and methods
- 14. Actions
