注意：需要引入libz.dylib框架// UnzippingNSString *zipPath = @"path_to_your_zip_file";NSString *destinationPath =@"path_to_the_folder_where_you_want_it_unzipped";[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];// ZippingNSString *zippedPath = @"path_where_you_want_the_file_created";NSArray *inputPaths = [NSArray arrayWithObjects: [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"], [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"] nil];[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths]; 一、技术方案
1.第三方框架：SSZipArchive 2.依赖的动态库：libz.dylib二、压缩1
1.第一个方法 /** zipFile ：产生的zip文件的最终路径 directory ： 需要进行的压缩的文件夹路径 */[SSZipArchive createZipFileAtPath:zipFile withContentsOfDirectory:directory]; 2.第一个方法
/** zipFile ：产生的zip文件的最终路径 files ： 这是一个数组，数组里面存放的是需要压缩的文件的路径 files = @[@”/Users/apple/Destop/1.png”, @”/Users/apple/Destop/3.txt”] */[SSZipArchive createZipFileAtPath:zipFile withFilesAtPaths:files]; 三、解压缩
/** zipFile ：需要解压的zip文件的路径 dest ： 解压到什么地方 */[SSZipArchive unzipFileAtPath:zipFile toDestination:dest]; #import "MalJobViewController.h"#import "SSZipArchive.h"#define MalJobFileBoundary @"heima"#define MalJobNewLine @"\r\n"#define MalJobEncode(str) [str dataUsingEncoding:NSUTF8StringEncoding]@interface MalJobViewController ()@end@implementation MalJobViewController- (void)viewDidLoad{ [super viewDidLoad];}- (NSString *)MIMEType:(NSURL *)url{ // 1.创建一个请求 NSURLRequest *request = [NSURLRequest requestWithURL:url]; // 2.发送请求（返回响应） NSURLResponse *response = nil; [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil]; // 3.获得MIMEType return response.MIMEType;}- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ NSString *caches = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]; // 0.获得需要压缩的文件夹 NSString *images = [caches stringByAppendingPathComponent:@"images"]; // 1.创建一个zip文件（压缩） NSString *zipFile = [caches stringByAppendingPathComponent:@"images.zip"]; BOOL result = [SSZipArchive createZipFileAtPath:zipFile withContentsOfDirectory:images]; if(result) { NSString *MIMEType = [self MIMEType:[NSURL fileURLWithPath:zipFile]]; NSData *data = [NSData dataWithContentsOfFile:zipFile]; [self upload:@"images.zip" mimeType:MIMEType fileData:data params:@{@"username" : @"lisi"}]; }}- (void)upload:(NSString *)filename mimeType:(NSString *)mimeType fileData:(NSData *)fileData params:(NSDictionary *)params{ // 1.请求路径 NSURL *url = [NSURL URLWithString:@"http://192.168.15.172:8080/Server/upload"]; // 2.创建一个POST请求 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; request.HTTPMethod = @"POST"; // 3.设置请求体 NSMutableData *body = [NSMutableData data]; // 3.1.文件参数 [body appendData:MalJobEncode(@"--")]; [body appendData:MalJobEncode(MalJobFileBoundary)]; [body appendData:MalJobEncode(MalJobNewLine)]; NSString *disposition = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"", filename]; [body appendData:MalJobEncode(disposition)]; [body appendData:MalJobEncode(MalJobNewLine)]; NSString *type = [NSString stringWithFormat:@"Content-Type: %@", mimeType]; [body appendData:MalJobEncode(type)]; [body appendData:MalJobEncode(MalJobNewLine)]; [body appendData:MalJobEncode(MalJobNewLine)]; [body appendData:fileData]; [body appendData:MalJobEncode(MalJobNewLine)]; // 3.2.非文件参数 [params enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) { [body appendData:MalJobEncode(@"--")]; [body appendData:MalJobEncode(MalJobFileBoundary)]; [body appendData:MalJobEncode(MalJobNewLine)]; NSString *disposition = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"", key]; [body appendData:MalJobEncode(disposition)]; [body appendData:MalJobEncode(MalJobNewLine)]; [body appendData:MalJobEncode(MalJobNewLine)]; [body appendData:MalJobEncode([obj description])]; [body appendData:MalJobEncode(MalJobNewLine)]; }]; // 3.3.结束标记 [body appendData:MalJobEncode(@"--")]; [body appendData:MalJobEncode(MalJobFileBoundary)]; [body appendData:MalJobEncode(@"--")]; [body appendData:MalJobEncode(MalJobNewLine)]; request.HTTPBody = body; // 4.设置请求头(告诉服务器这次传给你的是文件数据，告诉服务器现在发送的是一个文件上传请求) NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", MalJobFileBoundary]; [request setValue:contentType forHTTPHeaderField:@"Content-Type"]; // 5.发送请求 [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil]; NSLog(@"%@", dict); }];}@end #import "MalJobViewController.h"#import "SSZipArchive.h"@implementation MalJobViewController- (void)viewDidLoad{ [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib.}- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ NSURL *url = [NSURL URLWithString:@"http://localhost:8080/Server/resources/images.zip"]; NSURLSessionDownloadTask *task = [[NSURLSession sharedSession] downloadTaskWithURL:url completionHandler:^(NSURL *location, NSURLResponse *response, NSError *error) { NSString *caches = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]; [SSZipArchive unzipFileAtPath:location.path toDestination:caches]; }]; [task resume];}@end转载地址：http://cnlxx.baihongyu.com/
