Iphone NSCoding帮助非常奇怪的错误访问解除分配的实例
在我的代码中,我将数组存储在内存中。。。无需发出HTML请求即可获取它。 第一次,当我填充数组时,一切都正常。。。当我从内存中加载数组并将其加载到表中时,问题就会出现 这就是课堂Iphone NSCoding帮助非常奇怪的错误访问解除分配的实例,iphone,ios,objective-c,nscoding,Iphone,Ios,Objective C,Nscoding,在我的代码中,我将数组存储在内存中。。。无需发出HTML请求即可获取它。 第一次,当我填充数组时,一切都正常。。。当我从内存中加载数组并将其加载到表中时,问题就会出现 这就是课堂 @interface SubscriptionArray : NSObject{ NSString *title; NSString *source; NSString *htmlUrl; NSInteger count; } @property (nonatomic,retain)

数组在委托中声明为(与3个不同的类共享)
我是这样装的
[onlySubsriptions removeAllObjects];
self.onlySubsriptions = [NSKeyedUnarchiver unarchiveObjectWithFile:fullFileName];
我在cellForRowAtIndexPath中收到一个错误
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
TDBadgedCell *cell = [[[TDBadgedCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
SubscriptionArray * element=[[SubscriptionArray alloc]init];
if (indexPath.section==0) {
NSLog(@"CASO SPECIALELEMENTS");
element =[delegate.reader.specialElements objectAtIndex:[indexPath row]];
}
if (indexPath.section==1) {
NSLog(@"CASO CATEGORIA");
element =[delegate.reader.categories objectAtIndex:[indexPath row]];
}
if (indexPath.section==2) {
NSLog(@"CASO SUBSCRIPTIONS");
element =[delegate.reader.onlySubsriptions objectAtIndex:[indexPath row]];
}
例如,我确信我有2个元素,CellForRowatineXpath在开始加载第一个元素(元素0)时抛出异常。。。上面写着释放实例
我确信问题出在编码上,因为当我第一次得到数组时,一切都很好。。。只有在下次加载本地存储的阵列时,问题才会出现

为了处理这种异常,您可以使用malloc工具找出僵尸并修复它。
产品>配置文件将启动仪器,然后您应该有一个名为“Malloc”的“跟踪模板”。这可能对您有用。使用“NSZombie”检查哪个实例是DealLocate。我已经在回答中添加了一些信息。。。我不明白我的代码出了什么问题……你能帮我一下吗?-您的7行导致了问题,我可以部分地将其视为
[SubscriptionsViewController table…]
