Objective-C Language Structs Defining a Structure and Accessing Structure Members
Example
The format of the struct statement is this:
struct [structure tag]
{
member definition;
member definition;
...
member definition;
} [one or more structure variables];
Example: declare the ThreeFloats structure:
typedef struct {
float x, y, z;
} ThreeFloats;
@interface MyClass
- (void)setThreeFloats:(ThreeFloats)threeFloats;
- (ThreeFloats)threeFloats;
@end
Sending an instance of MyClass the message valueForKey: with the parameter @"threeFloats" will invoke the MyClass method threeFloats and return the result wrapped in an NSValue.
