Question

我正在寻找一种使用arm64支持在ios上压缩和解压缩文件的方法。我正在寻找Github，但他们不支持arm64。是否已有一个可立即使用的zip和解压缩文件库。（如果你知道如何整合7zip，bzip2，gzip，rar的话，我会爱你的）

我现在正在使用SSZipArchive，但它无效：

#import "SSZipArchive.h"

NSArray *nameWithoutExtention = [[[[self files] objectAtIndex:indexPath.row] lastPathComponent] componentsSeparatedByString:@"."];
NSString *fileName = [nameWithoutExtention objectAtIndex:0];
NSString *destPath = [NSString stringWithFormat:@"%@/%@", self.directory, fileName];
[fileManager createDirectoryAtPath:destPath withIntermediateDirectories:YES attributes:nil error:nil];
[SSZipArchive unzipFileAtPath:[[self files] objectAtIndex:indexPath.row] toDestination:destPath];

您可以查看official SSZipArchive Objective-C example（适用于iOS11，它是纯arm64）。

要压缩：

NSString *sampleDataPath = [[NSBundle mainBundle].bundleURL
                            URLByAppendingPathComponent:@"Sample Data"
                            isDirectory:YES].path;
NSString *zipPath = [self tempZipPath];
BOOL success = [SSZipArchive createZipFileAtPath:zipPath
                         withContentsOfDirectory:sampleDataPath];

要解压缩：

NSString *unzipPath = [self tempUnzipPath];
BOOL success = [SSZipArchive unzipFileAtPath:zipPath
                               toDestination:unzipPath];

tempZipPath和tempUnzipPath被声明为：

- (NSString *)tempZipPath {
  NSString *path = [NSString stringWithFormat:@"%@/\%@.zip",
                    NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0],
                    [NSUUID UUID].UUIDString];
  return path;
}

- (NSString *)tempUnzipPath {
  NSString *path = [NSString stringWithFormat:@"%@/\%@",
                    NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0],
                    [NSUUID UUID].UUIDString];
  NSURL *url = [NSURL fileURLWithPath:path];
  NSError *error = nil;
  [[NSFileManager defaultManager] createDirectoryAtURL:url
                           withIntermediateDirectories:YES
                                            attributes:nil
                                                 error:&error];
  if (error) {
    return nil;
  }
  return url.path;
}

如何在Objective C中解压缩，解压缩文件（arm64支持）
