Parse platform pQueryTableView内存

Parse platform pQueryTableView内存,parse-platform,pfquerytableviewcontrolle,Parse Platform,Pfquerytableviewcontrolle,我一直在使用PFQueryTableView处理图像和文本。实施此代码后: - (id)initWithCoder:(NSCoder *)aDecoder { self = [super initWithClassName:@"Story"]; self = [super initWithCoder:aDecoder]; if (self) { // This table displays items in the Todo class self.par

我一直在使用
PFQueryTableView
处理图像和文本。实施此代码后:

-  (id)initWithCoder:(NSCoder *)aDecoder {
     self = [super initWithClassName:@"Story"];
     self = [super initWithCoder:aDecoder];
   if (self) { // This table displays items in the Todo class
       self.parseClassName = @"Story";
       self.pullToRefreshEnabled = YES;
       self.paginationEnabled = YES;
       self.objectsPerPage = 25;
   }
  return self;
 }

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

if (self.objects.count == 0) {
    query.cachePolicy = kPFCachePolicyCacheThenNetwork;
}
[query orderByDescending:@"createdAt"];


return query;
 }


 - (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath
                    object:(PFObject *)object {
static NSString *cellIdentifier = @"cell";

PFTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell) {
    cell = [[PFTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
                                  reuseIdentifier:cellIdentifier];
}

// Configure the cell to show todo item with a priority at the bottom
cell.textLabel.text = object[@"snapDetails"];

PFFile *thumbnail = [object objectForKey:@"snap"];
cell.imageView.image = [UIImage imageNamed:@"placeholder.jpg"];
cell.imageView.file = thumbnail;
return cell;
}
日志给了我一个奇怪的警告:

[/BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreUI/CoreUI-
371.4/Bom/Storage/BOMStorage.c:522]不是BOMStorage文件


还有一个常规内存警告。偶尔该应用程序也会崩溃,
XCode
会显示一条消息,声称它与我的
iPhone
失去了连接。检查内存使用情况时,随着表格的上升或下降,内存会继续增加,就好像图像(屏幕大小)在离开屏幕时永远不会释放一样。关于可能发生的事情有什么想法吗?

几乎在所有情况下,这都是无害的,除非您的url错误。要使BOMStorage文件更严重,您可以添加以下内容:

urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
此外,您还可以选择其他替换方法:

[image stretchableImageWithLeftCapWidth:0 topCapHeight:0]  forState:UIControlStateNormal]
