我有以下 json 字符串:
{"suit_id": 2427;
"suits": "http://img.prettyyes.com/1137-4930-1446175512.jpeg;http://img.prettyyes.com/1137-7665-1446175512.jpeg;http://img.prettyyes.com/1137-4783-1446175512.jpeg"}
因此,当使用 mantle 解析带有以下文件的 json 字符串时
测试模型.h
@interface testModel : MTLModel <MTLJSONSerializing>
@property (nonatomic, strong) NSString *suit_id;
@property (nonatomic, strong) NSString *suits;
@end
测试模型.m
@implementation testModel
+ (NSDictionary *) JSONKeyPathsByPropertyKey {
return @{
"suit_id": "suit_id",
"suits": "suits"
};
}
@end
我想如何将西装从字符串转换为具有多个 url 的 NSArray,所以我做了以下操作:
测试模型.h
@interface testModel : MTLModel <MTLJSONSerializing>
@property (nonatomic, strong) NSString *suit_id;
@property (nonatomic, strong) NSArray *suits;
@end
测试模型.m
@implementation testModel
+ (NSDictionary *) JSONKeyPathsByPropertyKey {
return @{
"suit_id": "suit_id",
"suits": "suits"
};
}
+ (NSValueTransformer *) suitsJSONTransform {
return [MTLValueTransformer transformerUsingForwardBlock:^(NSString *str, BOOL *success, NSError **error){
return [[str componentsSeparatedByString:@";"] mutableCopy];
}];
}
@end
但它不起作用。结果为零。当我覆盖错误的功能时?
