ios - 如何从 NSDictionary 数组中获取值数组

Question

当我尝试在日志中打印 json 值数组时，我得到的是地址而不是值。这是我的编码方式。

NSData *jsonData = [json dataUsingEncoding:NSASCIIStringEncoding];
            NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];
            NSMutableArray *tempArray = [NSMutableArray arrayWithCapacity:jsonArray.count];
            NSMutableArray *anotherTempArray = [NSMutableArray arrayWithCapacity:jsonArray.count];
            NSDictionary *dict;
            for(dict in jsonArray)
            {
                NSString *projectName = dict[@"Name"];

                NSString *urlText = dict[@"Url"];
                NSLog(@"Url text in array = %@", urlText);

                NSString *attch = dict[@"attachmentes"];
                NSLog(@"Attached url in array = %@", attch);

                NSString *projID = dict[@"ProjectID"];
                NSLog(@"Project ID in array = %@", projID);

                SaveAttachment *saveAt = [[SaveAttachment alloc] initWithName:projectName withList:@"View"     withAttachment:@"View"];
                [tempArray addObject:saveAt];

                SaveProjectId *saveProj = [[SaveProjectId alloc] initWithProjectId:projID];
                saveProj.projectId = projID;
                [anotherTempArray addObject:saveProj];
             }
            array = tempArray;
            [self.tableViewProject reloadData];
            NSLog(@"Array of project IDs === %@", anotherTempArray); //Get values (array of project ids here.

        }

替换

SaveProjectId *saveProj = [[SaveProjectId alloc] initWithProjectId:projID];
saveProj.projectId = projID;
[anotherTempArray addObject:saveProj];

与

[anotherTempArray addObject:projID];
