Question

我试图将JSON数据添加到数组中。下面是代码......我不知道我哪里错了..

当我为arrayJSON保留一个Log时，结果如下：

Array Result: [{"ID_PROJECT":1,"NM_PROJECT":"TED"},{"ID_PROJECT":2,"NM_PROJECT":"DL"},{"ID_PROJECT":3,"NM_PROJECT":"PERD"},{"ID_PROJECT":4,"NM_PROJECT":"EPRS "},{"ID_PROJECT":5,"NM_PROJECT":"MSCS"}]

NSArray *arrayJSON = [NSJSONSerialization JSONObjectWithData:urlData
                                                             options:NSJSONReadingAllowFragments
                                                               error:&error];

        NSMutableArray *arrayResult = [NSMutableArray array];

        for(NSDictionary *dictJSON in arrayJSON){

            [arrayResult addObject: [dictJSON objectForKey:@"NM_PROJECT"]];
        }

        NSLog(@"Array Result: %@", arrayResult);

以下是错误代码：

Array Result: [{"ID_PROJECT":1,"NM_PROJECT":"TED"},{"ID_PROJECT":2,"NM_PROJECT":"DL"},{"ID_PROJECT":3,"NM_PROJECT":"PERD"},{"ID_PROJECT":4,"NM_PROJECT":"EPRS "},{"ID_PROJECT":5,"NM_PROJECT":"MSCS"}]

NSMutableArray *array = [Array Result JSONValue];
[array retain];


NSLog(@"Array Result: %@", array);

附加数组NSDictionary时出错
