我被困在这个方法中,我不知道为什么! 任何人都可以指向我的一些源代码? 非常感谢! 这是我的源代码:为NSData分配数据时发生卡滞/泄漏?
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
.......
readData = [readFileHandle readDataOfLength:defaultLen]
NSData *decryptedData = nil;
//check is last buffer of file
NSUInteger exLen = [readData length] % 16;
NSUInteger decryptionLen = [readData length] - exLen;
NSData *dataForDecryption = nil;
if(exLen != 0)
{
stuck at here-> [readData getBytes:dataForDecryption length:decryptionLen];
//
decryptedData = [dataForDecryption AES256DecryptWithKey:KEY];
self.isEndOfFile = YES;
}
else
decryptedData = [readData AES256DecryptWithKey:KEY];
[readFileHandle closeFile];
.......
[pool drain];
我已经使用了一些功能,如:
NSData *dataForDecryption = [[[NSData alloc] initWithBytes:readData length:decryptionLen]autorelease];
NSData *dataForDecryption = [NSData dataWithBytes:readData length:decryptionLen];
,但我得到了同样的错误。 当我使用 dataForDecryption = [readFileHandle readDataOfLength:decryptionLen];
它坚持在上面的pos和大小读为0,虽然它不是EOF。
感谢
不错的推荐,谢谢Caleb :) – 2012-03-26 02:09:11
