我被困在這個方法中,我不知道爲什麼! 任何人都可以指向我的一些源代碼? 非常感謝! 這是我的源代碼:爲NSData分配數據時發生卡滯/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];
我已經使用了一些功能,如:
NSData *dataForDecryption = [[[NSData alloc] initWithBytes:readData length:decryptionLen]autorelease];
NSData *dataForDecryption = [NSData dataWithBytes:readData length:decryptionLen];
,但我得到了同樣的錯誤。 當我使用 dataForDecryption = [readFileHandle readDataOfLength:decryptionLen];
它堅持在上面的pos和大小讀爲0,雖然它不是EOF。
感謝
不錯的推薦,謝謝Caleb :) – 2012-03-26 02:09:11
