The Implementation File (.m)
The implementation file (.m) holds all of the method headers and the code for those methods.
Example:
#import "MyClassName.h"
@implementation MyClassName
// methods and their code go here
-(IBAction) respondToTap:(id) sender
{
// your code for this method goes here
}
-(void) convertTemperature
{
// your code for this method goes here
}
@end
