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 = [NSMutableDictionarydictionary];
unsignedint count =0;
objc_property_t *properties =class_copyPropertyList([XXXXX class], &count);
for (int i =0; i < count; i++) {
constchar *name =property_getName(properties[i]);
NSString *propertyName = [NSStringstringWithUTF8String:name];
id propertyValue = [modelvalueForKey:propertyName];
if (propertyValue) {
[userDic setObject:propertyValueforKey:propertyName];
}
}
free(properties);
return userDic;
}
