//拼接补丁打包目录

[[NSFileManager defaultManager] removeItemAtPath:patchDirectory error:NULL];
[[NSFileManager defaultManager] createDirectoryAtPath:patchDirectory withIntermediateDirectories:YES attributes:nil error:NULL];

//将数据写到制定打包文件目录

//计算补丁的MD5值

//比对文件MD5值与服务器提供的MD5值
if (hashCode && entity.hashCode && [hashCode isEqualToString:entity.hashCode]) {
