1、ZipArchive 方式

• ZipArchive 只能对 zip 类文件进行压缩和解压缩

• GitHub 网址：https://github.com/ZipArchive/ZipArchive

• ZipArchive 使用 ARC

• 添加 ZipArchive

      // 添加第三方库文件
      ZipArchive
  
      // 包含系统动态库
      libz.tbd (libz.dylib)
  
      // 包含头文件
      #import "ZipArchive.h"

• ZipArchive 压缩

  • 文件压缩

        // 目标路径
        NSString *destinationFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 源路径，待压缩的文件                            
        NSArray *resourcesFilePaths = @[@"/Users/JHQ0228/Desktop/test1.rtf",
                                      @"/Users/JHQ0228/Desktop/test2.rtf"];
    
        BOOL result = [SSZipArchive createZipFileAtPath:destinationFilePath 
                                       withFilesAtPaths:resourcesFilePaths];

  • 文件夹压缩

        // 目标路径
        NSString *destinationFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 源路径，待压缩的文件夹
        NSString *resourcesDirPath = @"/Users/JHQ0228/Desktop/test";
    
        BOOL result = [SSZipArchive createZipFileAtPath:destinationFilePath 
                                withContentsOfDirectory:resourcesDirPath];

• ZipArchive 解压缩

  • 普通解压

        // 源路径，待解压缩的文件
        NSString *resourcesFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 目标路径
        NSString *destinationDirPath = @"/Users/JHQ0228/Desktop/test";
    
        BOOL result = [SSZipArchive unzipFileAtPath:resourcesFilePath 
                                      toDestination:destinationDirPath];

  • 密码解压

        // 源路径，待解压缩的文件
        NSString *resourcesFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 目标路径
        NSString *destinationDirPath = @"/Users/JHQ0228/Desktop/test";
    
        BOOL result = [SSZipArchive unzipFileAtPath:resourcesFilePath 
                                      toDestination:destinationDirPath 
                                          overwrite:YES 
                                           password:@"password" 
                                              error:nil];

  • 协议解压

        // 源路径，待解压缩的文件
        NSString *resourcesFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 目标路径
        NSString *destinationDirPath = @"/Users/JHQ0228/Desktop/test";
    
        BOOL result = [SSZipArchive unzipFileAtPath:resourcesFilePath 
                                      toDestination:destinationDirPath 
                                           delegate:self];

  • 协议密码解压

        // 源路径，待解压缩的文件
        NSString *resourcesFilePath = @"/Users/JHQ0228/Desktop/test.zip";
    
        // 目标路径
        NSString *destinationDirPath = @"/Users/JHQ0228/Desktop/test";
    
        BOOL result = [SSZipArchive unzipFileAtPath:resourcesFilePath 
                                      toDestination:destinationDirPath 
                                          overwrite:YES 
                                           password:@"password" 
                                              error:NULL 
                                           delegate:self];

  • 协议方法

        - (void)zipArchiveProgressEvent:(unsigned long long)loaded total:(unsigned long long)total {
    
            NSLog(@"%f", (float)loaded/total);
        }

2、SARUnArchiveANY 方式

• SARUnArchiveANY 可以对 .zip, .rar, .7z 类文件进行压缩和解压缩。

• GitHub 网址：https://github.com/saru2020/SARUnArchiveANY

• SARUnArchiveANY 使用 ARC

• 添加 SARUnArchiveANY

      // 添加第三方库文件
      SARUnArchiveANY
  
      // 包含系统动态库
      libz.tbd (libz.dylib)
  
      // 包含头文件
      #import "SARUnArchiveANY.h"
      #import "LZMAExtractor.h"

• SARUnArchiveANY 解压缩

          NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Zip_Example" ofType:@"zip"];
          NSString *destPath = [self applicationDocumentsDirectory];
