macOS @synthesize problems

[blue-lion]

Hello, i am having problems with the synthesize/property statement.

In the header i write

@property int fillColor;

and in the implementation file i write

@synthesize fillColor;

I've read that setter methods are created this way so,when i use the function below, it should work...right?

[object1 setfillColor 2] ;

I get a message saying "[GraphicObject fillColor:]: unrecognized selector sent to instance 0x10010c6d0"

GraphicObject is my class.



obviously i've omitted all the commands from the headers/footers for clarity.



can anybody help?

Reread the reference docs on properties, paying particular attention to the capitalization algorithm for mapping property names onto method names.

First off, the basic syntax is off:

[object1 setfillColor:2] ; --- notice the colon

And I believe it would actually be:

[object1 setFillColor:2] ; --- capitalization.

That's the pretty standard notation with auto-created/called getters and setters

Capitalize?

I'm not at my Mac right now, but off the top of my head you may want to capitalize the "F" in setFillColor.

Thank you all for your help.

What they said. But your specific error is not a setter, but a getter. There should be no : after that selector.
