model中去掉多余的model屬性,即key,
- (void)setValue:(id)value forUndefinedKey:(NSString *)key
{
}
model中含有id,并且給model中的id重命名為id_, model中的.m中代碼如下:
-(void)setValue:(id)value forKey:(NSString *)key
{
???? [super setValue:value forKey:key];
???? if ([key isEqualToString:@"id"]) {
?????????? self.id_ = value;
???? }
}
