我的应用程序有一个名为 ServerRequest 的 NSOperation 类来处理网络任务。根据仪器,它正在疯狂地泄漏。此外,instruments 表示构建请求的代码正在泄漏,即使这不是 NSOperation。但是我在设置自动释放池方面遵循了 Apple 的建议,所以我不明白这可能是什么问题。任何人都可以帮忙吗?
我的部分代码如下:
-(void) main {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
self.data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; // lots of leakage here
[self postResult]; // leakage here too
[pool release];
}
和 postResult 方法(没有泄漏):
-(void) postResult {
// error handling code here
if (![self isCancelled])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSMutableDictionary *resultDictionary = [[NSMutableDictionary alloc]init];
if (self.data!=nil)
[resultDictionary setObject:self.data forKey:kDataKey];
if (self.response!=nil)
[resultDictionary setObject:self.response forKey:kResponseKey];
if (self.error!=nil)
[resultDictionary setObject:self.error forKey:kErrorKey];
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
NSNotification *notification = [NSNotification notificationWithName: kDownloadCompleteName object: self userInfo: resultDictionary];
[resultDictionary release];
[center postNotification: notification];
[pool drain];
}
}
最后,dealloc:
- (void) dealloc {
self.request = nil;
self.data = nil;
self.mutableData = nil;
if (!self.error)
self.error = nil;
if (!self.response)
self.response = nil;
[super dealloc];
}
