iOS - 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：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"

      		// (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);
