I need some help in understanding the following code:
1. What is the meaning of ' at (no spam) ' in at (no spam) "Reload"
button = MakeTestButton(&button_rect, at (no spam) "Reload", content);
[button setTarget:web_view];
[button setAction: at (no spam) selector(reload:)];
2. Where I can find the definition of " at (no spam) selector(reload:)"? |

It means that this is an NSString* instead of a char*.
Quote: button = MakeTestButton(&button_rect, at (no spam) "Reload", content);
[button setTarget:web_view];
[button setAction: at (no spam) selector(reload:)];

Depends what you mean by that. The answer to my best guess at your
meaning is that at (no spam) selector returns a SEL object for the method name
provided as an argument. The result of the code that you show is that
when the button is clicked it will do this:
[web_view reload:button];

I saw a truck today that had "AAA Batteries / Delivered and Installed" on the
side. My first thought was: That's a really weird business model. How many
inept people have urgent need of skinny little battery cells? |

The at (no spam) prefix is an Objective-C extension that creates a literal
NSString which will exist for the duration of your application. |
