ios - 一次非常奇怪的车祸。我如何解决它？

Question

我遇到了一次非常奇怪的崩溃。我不释放数据变量。我的日志是:

[NSConcreteData retain]: message sent to deallocated instance 0xa446a00

和代码

- (void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data
{
 if (!isThreadCreated)
 {
    self.isThreadCreated = YES;
    [NSThread detachNewThreadSelector:@selector(createNewEncodingThread:) toTarget:self withObject:nil];
 }
 [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
 [[AudiobookAppDelegate delegate].dateManager saveTimeLastActivities];

 if(trackFile && !isFotrbidGetNewData)
 {
    if (data) 
    {
        self.downloadedLengthOfFile+= data.length;
        [encodingArray addObject:data];
    }
 }     
}

Answer 1

encodingArray 以某种方式发布，因此相关代码。
