我上传图像块智慧，在后台线程，每个块将大小为512kb，据我所知，我已经照顾使用版本，nsautoreleasepool内存泄漏的照顾。 以下是上传图片chunkwise的代码。NSThread导致内存泄漏iPhone
- (void)FetchDataFromDB : (NSNumber *) isOffline
{
@autoreleasepool {
@try {
NSLog(@"FetchDatafromDB");
isThreadStarted = YES;
VYukaDBFunctions *vdb = [VYukaDBFunctions getInstance];
NSMutableArray *fileNames = [vdb GetFileNames:[isOffline integerValue]];
for(int j=0 ; j<[fileNames count] ; j++)
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString * filename = fileNames [j] ;
int _outgoingMsgId = [[vdb SelectMsgId:filename] intValue];
int _totalchunk =[[vdb SelectTotalChunk:filename]intValue];
int currentChunk = [vdb GetCurrentChunk:filename];
for(int i=currentChunk ; i <= _totalchunk ; i++)
{
NSAutoreleasePool *innerPool = [[NSAutoreleasePool alloc] init];
NSString *AsyncRequest = [[NSString alloc] init];
AsyncRequest = [vdb SelectAsyncRequest: i : _outgoingMsgId];
if(![AsyncRequest isEqual:@""])
{
BOOL status = [self UploadChunkWise :AsyncRequest : 1 : i : vdb : filename : _outgoingMsgId];
// AsyncRequest = NULL;
// [AsyncRequest release];
if(status){
if(i==_totalchunk)
{
NSLog(@"Deleting from medialist , FileName :%@", filename);
[vdb DeleteFromMediaList : filename];
}
}
else{
[vdb DeleteFromMediaList : filename];
break;
}
}
[innerPool drain];
}
[pool drain];
}
[fileNames removeAllObjects];
// [fileNames release];
//recurssive call to check any pending uploads..
if([[vdb GetFileNames:[isOffline integerValue]] count] > 0)
{
NSLog(@"Calling Recursively..");
[self FetchDataFromDB:[isOffline integerValue]];
}
}
@catch (NSException *exception) {
NSLog(@"Exception caught on Uploading from FetchDataFromDB:%@", exception);
}
@finally {
}
}
NSLog(@"thread quit ");
isThreadStarted = NO;
[NSThread exit];
}
-(BOOL) UploadChunkWise :(NSString *) AsyncRequest : (int) count : (int)currentChunk : (VYukaDBFunctions *) vdb : (NSString *) currentFileName : (int) outgoingMsgId
{
NSHTTPURLResponse *response ;
NSError *error;
//Yes, http
NSMutableURLRequest *httpRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"Url goes here"]];
NSData* data = [AsyncRequest dataUsingEncoding:NSUTF8StringEncoding];
[httpRequest setHTTPMethod:@"POST"];
[httpRequest setHTTPBody:data];
[httpRequest setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
NSData *returnedData = [NSURLConnection sendSynchronousRequest: httpRequest returningResponse:&response error:&error] ;
NSString *result= [[NSString alloc] initWithData:returnedData encoding:NSASCIIStringEncoding];
[httpRequest release];
returnedData= NULL;
[returnedData release];
data = NULL;
[data release];
if ([result rangeOfString:@"success"].location != NSNotFound)
{
NSLog(@" success");
[vdb DeleteCurrentChunkFromOutgoingTable:currentChunk : outgoingMsgId];
[result release];
return YES ;
}
else if ([result rangeOfString:@"fail"].location != NSNotFound)
{
[result release];
if (count < 3) {
return [self UploadChunkWise :AsyncRequest : count+1 : currentChunk: vdb : currentFileName : outgoingMsgId ];
}
else
{
NSLog(@" failed");
[vdb DeleteAllCurrentFileChunksFromOutgoingTable:currentFileName];
return NO ;
}
}
return NO;
}
我开始线程如下
[NSThread detachNewThreadSelector:@selector(FetchDataFromDB:) toTarget:self withObject:[NSNumber numberWithInt:0]];
问题是上传9〜12块后，我收到内存错误。我得到4至5倍的内存警告，然后在应用程序崩溃。在控制台我收到内存警告第一次在应用程序委托类，其次是扩展UIViewController 4个类。为什么我得到应用程序委托和其他类的UIViewController类的警告。为什么我必须释放其他类的对象，如果单独的线程给我内存错误？我在这里做错了什么？我不能使用ARC，因为我已经将它与旧的代码整合在一起，这不是使用ARC，我尝试启用ARC类明智的，但它的工作。任何人都可以帮助我找出这个代码中是否有任何内存泄漏。建议是欢迎和appreciated.Thanks提前..
