文件的压缩与解压
压缩
/**
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];
/**
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];
解压
/**
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];
SSZipArchive 依赖于lib.dylib动态库
#import "SSZipArchive.h"
NSString *caches = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
// .获得需要压缩的文件夹
NSString *images = [caches stringByAppendingPathComponent:@"images"];
// .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"}];
}
文件解压
NSURL *url = [NSURL URLWithString:@"http://images.zip"];
NSURLSessionDownloadTask *task = [[NSURLSession sharedSession] downloadTaskWithURL:url completionHandler:^(NSURL *location, NSURLResponse *response, NSError *error) {
NSString *caches = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
//当前路径解压到指定的文件路径
[SSZipArchive unzipFileAtPath:location.path toDestination:caches];
}];
[task resume];
