Based on C LibYAML library (http://pyyaml.org/wiki/LibYAML) by Kirill Simonov.
YAML.framework provides support for YAML (de/)serialisation similarly to standard NSPropertyListSerialization.
It's fast and compatible with iOS.
NSInputStream *stream = [[NSInputStream alloc] initWithFileAtPath: @"yaml/items.yaml"];
// or [[NSInputStream alloc] initWithURL: ...]
// You can use objectsWithYAMLStream:options:error instead to get all YAML documents.
//
// Alternativelly object(s)WithYAMLData:options:error or object(s)WithYAMLString:options:error.
id yaml = [YAMLSerialization objectWithYAMLStream: stream
options: kYAMLReadOptionStringScalars
error: nil];
// Dump Objective-C object description.
printf("%s", [[yaml description] UTF8String]);For input YAML file:
items:
- name: Foo
- name: BarShould print dump string similar to:
(
{
items = (
{
name = Foo;
},
{
name = Bar;
}
);
}
)
The following class methods are defined on YAMLSerialization class.
// Returns all document objects from parsed YAML stream.
+ (NSMutableArray *) objectsWithYAMLStream: (NSInputStream *) stream
options: (YAMLReadOptions) opt
error: (NSError **) error;
// Returns all document objects from parsed YAML data.
+ (NSMutableArray *) objectsWithYAMLData: (NSData *) data
options: (YAMLReadOptions) opt
error: (NSError **) error;
// Returns all document objects from parsed YAML string.
+ (NSMutableArray *) objectsWithYAMLString: (NSString *) string
options: (YAMLReadOptions) opt
error: (NSError **) error;
// Returns first object from parsed YAML stream.
+ (id) objectWithYAMLStream: (NSInputStream *) stream
options: (YAMLReadOptions) opt
error: (NSError **) error;
// Returns first object from parsed YAML data.
+ (id) objectWithYAMLData: (NSData *) data
options: (YAMLReadOptions) opt
error: (NSError **) error;
// Returns first object from parsed YAML string.
+ (id) objectWithYAMLString: (NSString *) string
options: (YAMLReadOptions) opt
error: (NSError **) error;// Returns YES on success, NO otherwise.
+ (BOOL) writeObject: (id) object
toYAMLStream: (NSOutputStream *) stream
options: (YAMLWriteOptions) opt
error: (NSError **) error;
// Caller is responsible for releasing returned object.
+ (NSData *) createYAMLDataWithObject: (id) object
options: (YAMLWriteOptions) opt
error: (NSError **) error NS_RETURNS_RETAINED;
// Returns autoreleased object.
+ (NSData *) YAMLDataWithObject: (id) object
options: (YAMLWriteOptions) opt
error: (NSError **) error;
// Caller is responsible for releasing returned object.
+ (NSString *) createYAMLStringWithObject: (id) object
options: (YAMLWriteOptions) opt
error: (NSError **) error NS_RETURNS_RETAINED;
// Returns autoreleased object.
+ (NSString *) YAMLStringWithObject: (id) object
options: (YAMLWriteOptions) opt
