File Archive/UnArchive 文件压缩/解压

1、ZipArchive 方式

• ZipArchive 只能对 zip 类文件进行压缩和解压缩

• GitHub 网址：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：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

  - (void)unZip {
      NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Zip_Example" ofType:@"zip"];
      NSString *destPath = [self applicationDocumentsDirectory];

      [self unArchive:filePath andPassword:@"SARUnArchiveANY_RAR" destinationPath:destPath];
  }
  
  - (void)Unzip7z {
      NSString *archiveFilename = @"example.7z";
      NSString *archiveResPath = [[NSBundle mainBundle] pathForResource:archiveFilename ofType:nil];
      NSAssert(archiveResPath, @"can't find .7z file");
      NSString *destPath = [self applicationDocumentsDirectory];
      [self unArchive:archiveResPath andPassword:nil destinationPath:destPath];
  }
  
  - (void)unArchive: (NSString *)filePath andPassword:(NSString*)password destinationPath:(NSString *)destPath {
      
      NSAssert(filePath, @"can't find filePath");
      
      SARUnArchiveANY *unarchive = [[SARUnArchiveANY alloc] initWithPath:filePath];
      
      if (password != nil && password.length > 0) {
      	unarchive.password = password;
      }
      
      if (destPath != nil) {
      
          // (Optional). If it is not given, then the file is unarchived in the same location of its archive/file.
      	unarchive.destinationPath = destPath;
      }
      
      unarchive.completionBlock = ^(NSArray *filePaths) {
      
      	NSLog(@"For Archive : %@", filePath);
      
      	if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"US Presidents://"]]) {
          
          	NSLog(@"US Presidents app is installed.");
          	[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"US Presidents://"]];
      	}
      
      	for (NSString *filename in filePaths) {
          	NSLog(@"File: %@", filename);
      	}
      };
      
      unarchive.failureBlock = ^(){
      	NSLog(@"Cannot be unarchived");
      };
      
      [unarchive decompress];
  }
  
  - (void)handleFileFromURL:(NSString *)filePath {
      NSLog(@"*********       FILES FROM THE OTHER APPS       *********");
      [self unArchive:filePath andPassword:nil destinationPath:nil];
  }
  
  - (NSString *) applicationDocumentsDirectory {
      NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
      NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
      return basePath;
