Method Detail
| + (nullable id) parseJSON: | (NSString *) | json |
Parses a JSON string into an object.
- Parameters
-
json The JSON string to parse.
- Returns
- The root object of the object hierarchy that represents the data (either an NSArray or an NSDictionary), or
nilif the parsing failed.
| + (nullable id) parseJSON: | (NSString *) | json | |
| error: | (NSError **) | error | |
Parses a JSON string into an object.
- Parameters
-
json The JSON string to parse. error If not nil, the location at which to store a pointer to an NSError if the parsing fails.
- Returns
- The root object of the object hierarchy that represents the data (either an NSArray or an NSDictionary), or
nilif the parsing failed.
| + (NSString *) writeJSON: | (id) | object |
Writes an object hierarchy of data to a JSON string.
- Parameters
-
object The root object of the object hierarchy to encode. This must be either an NSArray or an NSDictionary.
- Returns
- An NSString containing the JSON encoding, or
nilif the data could not be encoded.
| + (BOOL) isJSONString: | (NSString *) | actual | |
| equivalentTo: | (NSString *) | expected | |
Tests if two JSON strings are equivalent.
This does a deep comparison of the JSON data in the two strings, but ignores any differences in the ordering of keys within a JSON object. For example, { "width":64, "height":32 } is considered to be equivalent to { "height":32, "width":64 }.
| + (BOOL) isJSONObject: | (id) | actual | |
| equivalentTo: | (id) | expected | |
Tests if two JSON objects are equivalent.
This does a deep comparison of the JSON data in the two objects, but ignores any differences in the ordering of keys within a JSON object. For example, { "width":64, "height":32 } is considered to be equivalent to { "height":32, "width":64 }.
