我有json,我想要mapp到模型类
{
"type": "FeatureCollection",
"features": [
{
"geometry": {
"coordinates": [100.0, 0.0, 129, 1356044399]
},
"properties": {
"name": "My first name",
"description": "Popular place"
}
},
{
"geometry": {
"coordinates": [100.0, 1.0, 127, 1356045399]
},
"properties": {
"name": "My second TIP",
"description": "Even more popular place"
}
}
]
}
我想把它放到一个类似这样的模型类中:
@property longitude (taken from coordinates index 0)
@property latitude (taken from coordinates index 1)
@property name
@property description
答案 0 :(得分:2)
嗯,我想出的解决方案如下:
两种型号:
@interface WTFeaturesModel
@property (nonatomic, strong) NSString *type;
@property (nonatomic, strong) NSArray *features;
@interface WTFeatureModel
@property (nonatomic, strong) NSDictionary *properties;
@property (nonatomic, strong) NSDictionary *geometry;
模型映射:
[featureMapping addAttributeMappingsFromArray:@[@"properties", @"geometry"]];
[featuresMapping addAttributeMappingsFromArray:@[ @"type"]];
[featuresMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"features" toKeyPath:@"features" withMapping:featureMapping]];
在我创建了这些模型后,我必须将数据映射到具有正确属性的其他模型。无论如何,这使得映射工作......
