PFQueryTableViewController多路段

Question

我下面这个论坛：https://parse.com/questions/using-pfquerytableviewcontroller-for-uitableview-sections

如果你去上面的链接和阅读题，你会看到，我想在我PFQueryTableViewController缔造出款款。复制上面的链接的代码形式后，我能够切断我的TableView就好了..它工作的很棒！这是我的问题。 （做这件事的最好方法就是举一个例子）。想象我有2个细胞的细胞3段中的每个部

当我点击A I得到的一个结果。当我点击B时，我得到B结果。 但是当我点击CI得到A，并且当我点击DI获得B.当我点击EI获得A并且当我点击FI获得B.

基本上它知道有部分，但它是使得它好像有1个部分连续重复（3）次。

这里是捕捉。 TableView中的单元显示正确的信息。它是在您点击传输错误信息的单元格之后。也许我错过了一些东西，但我不知道在哪里。

这里是我的代码：

@property (nonatomic, retain) NSMutableDictionary *sections; 
@property (nonatomic, retain) NSMutableDictionary *sectionToSportTypeMap; 

@implementation AllDataViewController 
@synthesize sections = _sections; 
@synthesize sectionToSportTypeMap = _sectionToSportTypeMap; 

- (id)initWithCoder:(NSCoder *)aCoder 
{ 
    self = [super initWithCoder:aCoder]; 
    if (self) { 
     // Custom the table 

     // The className to query on 
     self.parseClassName = @"schedule"; 
     self.textKey = @"name"; 
     self.pullToRefreshEnabled = YES; 

     self.paginationEnabled = YES; 
     self.objectsPerPage = 25; 
     self.sections = [NSMutableDictionary dictionary]; 
     self.sectionToSportTypeMap = [NSMutableDictionary dictionary]; 
    } 
    return self; 
} 

- (PFQuery *)queryForTable 
{ 
    PFQuery *query = [PFQuery queryWithClassName:self.parseClassName]; 

    // If Pull To Refresh is enabled, query against the network by default. 
    if (self.pullToRefreshEnabled) { 
     query.cachePolicy = kPFCachePolicyNetworkOnly; 
    } 

    // If no objects are loaded in memory, we look to the cache first to fill the table 
    // and then subsequently do a query against the network. 
    if (self.objects.count == 0) { 
     query.cachePolicy = kPFCachePolicyCacheThenNetwork; 
    } 


     [query orderByAscending:@"order"]; 

    return query; 
} 
- (void) objectsDidLoad:(NSError *)error 
{ 
    [super objectsDidLoad:error]; 
    [self.sections removeAllObjects]; 
    [self.sectionToSportTypeMap removeAllObjects]; 

    NSInteger section = 0; 
    NSInteger rowIndex = 0; 
    for (PFObject *object in self.objects) { 
     NSString *sportType = [object objectForKey:@"order"]; 
     NSMutableArray *objectsInSection = [self.sections objectForKey:sportType]; 
     if (!objectsInSection) { 
      objectsInSection = [NSMutableArray array]; 

      // this is the first time we see this sportType - increment the section index 
      [self.sectionToSportTypeMap setObject:sportType forKey:[NSNumber numberWithInt:section++]]; 
     } 

     [objectsInSection addObject:[NSNumber numberWithInt:rowIndex++]]; 
     [self.sections setObject:objectsInSection forKey:sportType]; 
    } 
} 


- (PFObject *)objectAtIndexPath:(NSIndexPath *)indexPath { 
    NSString *sportType = [self sportTypeForSection:indexPath.section]; 
    NSArray *rowIndecesInSection = [self.sections objectForKey:sportType]; 
    NSNumber *rowIndex = [rowIndecesInSection objectAtIndex:indexPath.row]; 
    return [self.objects objectAtIndex:[rowIndex intValue]]; 
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
    return self.sections.allKeys.count; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    NSString *sportType = [self sportTypeForSection:section]; 
    NSArray *rowIndecesInSection = [self.sections objectForKey:sportType]; 
    return rowIndecesInSection.count; 
}

}

    return [self.sectionToSportTypeMap objectForKey:[NSNumber numberWithInt:section]]; 
}

     NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; 
     //PFObject *selectedObject = [self objectAtIndexPath:indexPath]; 
     DataDetailViewController *destViewController = segue.destinationViewController; 

     PFObject *object = [self.objects objectAtIndex:indexPath.row]; 
     AllData *data = [[AllData alloc] init]; 
     data.title = [object objectForKey:@"title"]; 
     data.imageFile = [object objectForKey:@"imageFile"]; 
     data.date = [object objectForKey:@"date"]; 
     data.information = [object objectForKey:@"information"];

    } 
} 

Answer 1

如果你在你的桌子多个部分，但你只segueing在第一部分中的信息，无论你选择的部分，也许是由于该行的：

PFObject *object = [self.objects objectAtIndex:indexPath.row]; 

其中对象从self.objects阵列抓起是仅基于行依赖性而无需为节点上。因此，当你的代码现在，如果第2节中的第1行被选中，假设你的数据是标准的顺序（例如A，B，C，D等），你仍然会继续到第1行第1节为了让您的代码工作打算，你可能要改变这一行：

PFObject *object = [self.objects objectAtIndex:indexPath.row]; 

到

PFObject *object = [self.objects objectAtIndex:indexPath.row * (indexPath.section + 1)]; 

，这样你在（部分+ 1）乘访问self.objects阵列中正确的索引。

Answer 2

尝试它嵌套的IF ELSE语句，像这样

if (indexPath.section == 0) { 
     //A 
     if (indexPath.row == 0) { 
      PFObject *object = [self.messagesArray objectAtIndex:indexPath.row]; 
     } 
    }
