Ios 将嵌套模型类对象作为JSON api参数传递

我有一个模型类，它包含不同的属性，一些属性还包含另一个模型类的对象。我的问题是我想直接将模型类对象作为JSON api参数传递

请给我指路

前

我想将objUserModel作为参数传递给json api。 请建议我如何将objUserModel作为jsonapiparameters传递

感谢您的改进

您可以创建一个

模型对象

类，并将所有模型类更改为该类的子类。然后将

dictionaryWithPropertiesOfObject:

的实现更改为如下内容：

- (NSDictionary *)dictionaryWithPropertiesOfObject:(id)obj {
    NSMutableDictionary *dict = [NSMutableDictionary dictionary];
    unsigned count;
    objc_property_t *properties = class_copyPropertyList([obj class], &count);
    for (int i = 0; i < count; i++) {
        NSString *key = [NSString stringWithUTF8String:property_getName(properties[i])];
        if([obj valueForKey:key]!=nil){
            id targetObject = [obj valueForKey:key];
            if ([targetObject isKindOfClass:[ModelObject class]]){
                [dict setObject:[self dictionaryWithPropertiesOfObject: targetObject]  forKey:key];
            }
            else if ([targetObject isKindOfClass:[NSArray class]]){
                [dict setObject:[self arrayWithDictionariesForObjectsInArray: (NSArray *)targetObject] forKey:key];
            }
            else {
                [dict setObject:targetObject forKey:key];
            }
        }
    }
    free(properties);
    return [NSDictionary dictionaryWithDictionary:dict];
}

- (NSArray *) arrayWithDictionariesForObjectsInArray: (NSArray *) array {
    NSMutableArray *mutableArray = [[NSMutableArray alloc] init];
    for (id object in array){
        [mutableArray addObject:[self dictionaryWithPropertiesOfObject:object]];
    }
    return [NSArray arrayWithArray:mutableArray]; 
}

-（NSDictionary*）字典，其属性为对象：（id）obj{
NSMutableDictionary*dict=[NSMutableDictionary]；
无符号计数；
objc_property_t*properties=class_copyPropertyList（[obj class]，&count）；
for（int i=0；i

因此，

ModelObject

的所有实例都插入到字典中，并带有它们的字典表示形式。

为什么不试试呢？Kazunori，但我不想使用第三方工具。。任何其他建议到目前为止您尝试了什么？我最后使用了这个方法，但它仍然在嵌套的模型对象-（NSDictionary*）dictionaryWithPropertiesOfObject:（id）obj{NSMutableDictionary*dict=[NSMutableDictionary]；unsigned count；objc_property_t*properties=class_copyPropertyList（[obj class]，&count）；for（int i=0；i- (NSDictionary *)dictionaryWithPropertiesOfObject:(id)obj { NSMutableDictionary *dict = [NSMutableDictionary dictionary]; unsigned count; objc_property_t *properties = class_copyPropertyList([obj class], &count); for (int i = 0; i < count; i++) { NSString *key = [NSString stringWithUTF8String:property_getName(properties[i])]; if([obj valueForKey:key]!=nil){ id targetObject = [obj valueForKey:key]; if ([targetObject isKindOfClass:[ModelObject class]]){ [dict setObject:[self dictionaryWithPropertiesOfObject: targetObject] forKey:key]; } else if ([targetObject isKindOfClass:[NSArray class]]){ [dict setObject:[self arrayWithDictionariesForObjectsInArray: (NSArray *)targetObject] forKey:key]; } else { [dict setObject:targetObject forKey:key]; } } } free(properties); return [NSDictionary dictionaryWithDictionary:dict]; } - (NSArray *) arrayWithDictionariesForObjectsInArray: (NSArray *) array { NSMutableArray *mutableArray = [[NSMutableArray alloc] init]; for (id object in array){ [mutableArray addObject:[self dictionaryWithPropertiesOfObject:object]]; } return [NSArray arrayWithArray:mutableArray]; }
