創建zip文件引發洩漏

NSData * buffer = [fileHandle readDataOfLength:chunkSize];
                while ([buffer length] > 0)
                {
                    [streamBIG writeData:buffer];
                    offset += [buffer length];

                    [fileHandle seekToFileOffset:offset];
                    buffer = [fileHandle readDataOfLength:chunkSize];
                }

這段代碼是用來zip大小為25-30MB的批量文件，但是引起了崩潰。

最佳回答：

試試自動釋放：

           NSData * buffer = [fileHandle readDataOfLength:chunkSize];
            while ([buffer length] > 0)
            {
                @autoreleasepool
                {
                [streamBIG writeData:buffer];
                offset += [buffer length];

                [fileHandle seekToFileOffset:offset];
                buffer = [fileHandle readDataOfLength:chunkSize];
                }
            }
