Editing Mutator method (section)

===Objective-C===
Using traditional Objective-C 1.0 syntax, with manual reference counting as the one working on [[GNUstep]] on [[Ubuntu version history#1204|Ubuntu 12.04]]:
<syntaxhighlight lang="objc">
@interface Student : NSObject
{
    NSString *_name;
}

- (NSString *)name;
- (void)setName:(NSString *)name;

@end

@implementation Student

- (NSString *)name
{
    return _name;
}

- (void)setName:(NSString *)name
{
    [_name release];
    _name = [name retain];
}

@end
</syntaxhighlight>
Using newer Objective-C 2.0 syntax as used in [[Mac OS X 10.6]], [[iOS 4]] and [[Xcode]] 3.2, generating the same code as described above:
<syntaxhighlight lang="objc">
@interface Student : NSObject

@property (nonatomic, retain) NSString *name;

@end

@implementation Student

@synthesize name = _name;

@end
</syntaxhighlight>
And starting with [[OS X 10.8]] and [[iOS 6]], while using [[Xcode]] 4.4 and up, syntax can be even simplified:
<syntaxhighlight lang="objc">
@interface Student : NSObject

@property (nonatomic, strong) NSString *name;

@end

@implementation Student

//Nothing goes here and it's OK.

@end
</syntaxhighlight>
