对不起英语:( ....我知道用restkit编码简单的json。但是非常令人困惑的json如下所示。

输出将获得“成功”,“客户”和“allCustomers”,但“openingHour”值为NULL。[getCustomer_Mapping mapKeyPath:@"openingHour" toRelationship:@"customerRelationShip" withMapping:openingHour_Mapping];
像上面的代码是正确的吗?我不知道如何获取“openingHour”键的值。请帮助我编辑:
让我解释一下它是如何工作的:
最佳答案
看看它怎么运作:
NSDictionary *dictionary = [yourParser parse: jsonString];
for (int i= 0; i < [[dictionary valueForKey:@"customers"] count]; i++) {
NSArray *openingHourArray = [[[dictionary valueForKey:@"customers"] objectAtIndex:i] valueForKey: openingHour];
for(int j = 0; j <[openingHourArray count]; j++){
NSDictionary *openingHourDictionary = [openingHourArray objectAtIndex:i];
NSLog(@"openingHourDictionary =%@", openingHourDictionary);
}
}
这是为您准备的作业,请检查
valueForKey
返回的值是dict还是array。否则会导致应用程序崩溃。快乐的衣着.. :)
