实体类到另一个实体类传递数据

在chapterDC类中有一个selectedRegion，其中的区域数据需要传递到 regionDC。通过chapterDC来传递。chapterDC中有区域。

但是返回的结果不是0就是null。

-(NSMutableArray *)getAllChapters{    NSMutableArray *returnArray = [[NSMutableArray alloc] init];    NSString *url = [NSString stringWithFormat:@""%@get_all_chapters""kWSURL];    NSDictionary * returnDict = (NSDictionary *) [self callWebService:url];    if([[returnDict objectForKey:@""status""] isEqualToString:@""success""])    {        NSDictionary * responseDict = (NSDictionary *) [returnDict objectForKey:@""response""];        NSArray *resultArray = [responseDict objectForKey:@""result""];        for(NSDictionary *chapterDict in resultArray)        {            ChapterDC * chapter = [[ChapterDC alloc] init];            chapter.ChapterDC_ChapterID=[[chapterDict objectForKey:@""ChapterID""]intValue];            chapter.ChapterDC_ChapterName = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""ChapterName""]];            chapter.selectedRegion.RegionDC_RegionID=[ [chapterDict objectForKey:@""RegionID""]intValue];             NSLog(@""%d""chapter.selectedRegion.RegionDC_RegionID);            chapter.ChapterDC_AddressLine1 = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""AddressLine1""]];            chapter.ChapterDC_AddressLine2 = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""AddressLine2""]];            chapter.ChapterDC_AddressLine3 = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""AddressLine3""]];            chapter.ChapterDC_Email = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""Email""]];            chapter.ChapterDC_URL = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""URL""]];            chapter.ChapterDC_FacebookURL =[ NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""FacebookURL""]];            chapter.ChapterDC_LinkedInURL = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""LinkedInURL""]];            chapter.ChapterDC_PhoneNumber =[ NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""PhoneNumber""]];            chapter.ChapterDC_Postcode = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""Postcode""]];            chapter.ChapterDC_TwitterURL = [NSString stringWithFormat:@""%@"" [chapterDict objectForKey:@""TwitterURL""]];            NSDictionary * regionDict = (NSDictionary *) [returnDict objectForKey:@""region""];            {            chapter.selectedRegion = [[RegionDC alloc] init];            chapter.selectedRegion.RegionDC_RegionID = [[regionDict objectForKey:@""RegionID""]intValue];            NSLog(@""%d""chapter.selectedRegion.RegionDC_RegionID);            chapter.selectedRegion.RegionDC_RegionName = [NSString stringWithFormat:@""%@"" [regionDict objectForKey:@""RegionName""]];                NSLog(@""%@""chapter.selectedRegion.RegionDC_RegionName);            chapter.selectedRegion.RegionDC_ContactName = [NSString stringWithFormat:@""%@"" [regionDict objectForKey:@""ContactName""]];            chapter.selectedRegion.RegionDC_Mobile = [NSString stringWithFormat:@""%@"" [regionDict objectForKey:@""Mobile""]];            chapter.selectedRegion.RegionDC_Landline = [NSString stringWithFormat:@""%@"" [regionDict objectForKey:@""Landline""]];            chapter.selectedRegion.RegionDC_TrainingURL = [NSString stringWithFormat:@""%@"" [regionDict objectForKey:@""TrainingURL""]];            }            [returnArray addObject:chapter];        }    }    return returnArray;}
