iOS 对象转化为字典

iOS 对象转化为字典，在实际开发的过程中，很多时候我们需要上传数据，代码中我们用对象处理数据，上传我们就需要把对象转化为字典。

//对象转化为字典

-(NSMutableDictionary *)onereturnToDictionaryWithModel:(XXXXX*)model

{

NSMutableDictionary *userDic = [NSMutableDictionary dictionary];

unsigned int count = 0;

objc_property_t *properties = class_copyPropertyList([XXXXXclass], &count);

for (int i = 0; i < count; i++) {

const char *name = property_getName(properties[i]);

NSString *propertyName = [NSString stringWithUTF8String:name];

id propertyValue = [model valueForKey:propertyName];

if (propertyValue) {

[userDic setObject:propertyValue forKey:propertyName];

}

}

free(properties);

return userDic;

}
