iPhone有拉链解压缩吗? 3个答案

After StoreKit downloads the IAP content package it returns an NSURL to me which looks like this:

在StoreKit下载IAP内容包后,它会向我返回一个NSURL,如下所示:

file://localhost/private/var/mobile/Applications/45EF2B3A-3CAB-5A44-4B4A-631A122A4299/Library/Caches/BA32BC55-55DD-3AA4-B4AC-C2A456622229.zip/

Despite all sources I found claiming that StoreKit unzips the content package once downloaded, it hands me over a ZIP. This ZIP probably contains the file structure of the content package. But how do I unzip this?

尽管我发现所有来源都声称StoreKit在下载后解压缩了内容包,但它还是通过ZIP传递给我。此ZIP可能包含内容包的文件结构。但是我如何解压缩呢?

2 个解决方案

#1

Use SSZipArchive

You can unzip using this

您可以使用此解压缩

NSArray  *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *outputPath = [documentsDirectory stringByAppendingPathComponent:@"/ImagesFolder"];

NSString *zipPath = Your zip file path;

[SSZipArchive unzipFileAtPath:zipPath toDestination:outputPath delegate:self];

Hope it helps you.

希望它能帮到你。

Edit:

Quick method I created which takes url, downloads the zip and unzips it

我创建的快速方法,它需要url,下载zip并解压缩

-(void)downloadAndUnzip : (NSString *)sURL_p : (NSString *)sFolderName_p
{
    dispatch_queue_t q = dispatch_get_global_queue(0, 0);
    dispatch_queue_t main = dispatch_get_main_queue();
    dispatch_async(q, ^{
        //Path info
        NSURL *url = [NSURL URLWithString:sURL_p];
        NSData *data = [NSData  dataWithContentsOfURL:url];
        NSString *fileName = [[url path] lastPathComponent];
        NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:fileName];
        [data writeToFile:filePath atomically:YES];
        dispatch_async(main, ^


                 {
                       //Write To
                       NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                       NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
                       NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:sFolderName_p];

                       [SSZipArchive unzipFileAtPath:filePath toDestination:dataPath];

                   });
});

}
