SecureMappingKit保护JSON和模型之间的映射

SecureMappingKit 可以实现 JSON 数据和 Model 类之间安全的映射。

转换器包括：

• NSNumberTransformer,

• NSBooleanNumberTransformer, to be sure to have a NSNumber of a boolean

• NSStringTransformer,

• NSURLTransformer,

• NSArrayTransformer,

• NSDateTransformer,

• NSDecimalTransformer

使用：

- (id)objectForKey:(id)aKey expectedClass:(Class)expectedClass;
- (id)objectForKey:(id)aKey expectedClass:(Class)expectedClass withTransformerClass:(Class)transformerClass;
- (id)objectForKey:(id)aKey withTransformerBlock:(JMOTransformerBlock)transformerBlock;

- (NSNumber *)numberForKey:(id)aKey;
- (NSNumber *)boolNumberForKey:(id)aKey;
- (NSDecimalNumber *)decimalNumberForKey:(id)aKey;
- (NSString *)stringForKey:(id)aKey;
- (NSURL *)urlForKey:(id)aKey;
- (NSArray *)arrayForKey:(id)aKey;
- (NSDate *)dateForKey:(id)aKey usingDateFormat:(NSString *)dateFormat;
