解压缩应用内购买 iOS 的内容

Question

Apple 托管内容.zip下载，以防应用内购买。m 尝试解压缩这些内容，但已归档以使用 zipArchive 打开.zip文件。

ZipArchive* za = [[ZipArchive alloc] init];
za.delegate = self;
NSString *path = [download.contentURL path];
if([[NSFileManager defaultManager] fileExistsAtPath:path])
{
    NSLog(@"File Exists: %@", path);
}
else
{
    NSLog(@"file not exists: %@", path);
}

if( [za UnzipOpenFile:path] ) {
    if( [za UnzipFileTo:dir overWrite:YES] != NO )
    {
        NSLog(@"unzip data success");
        //unzip data success
        //do something
    }
    else
    {
        NSLog(@"unzip failed");
    }

    [za UnzipCloseFile];
}
else
{
    NSLog(@"unzip can't open file");
}

输出为

文件存在：....路径。。解压缩无法打开的文件

相反，如果我自己捆绑一个.zip文件，它工作正常

path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"module.zip"];
ZipArchive* za = [[ZipArchive alloc] init];
za.delegate = self;
if([[NSFileManager defaultManager] fileExistsAtPath:path])
{
    NSLog(@"File Exists: %@", path);
}
else
{
    NSLog(@"file not exists: %@", path);
}

if( [za UnzipOpenFile:path] ) {
    if( [za UnzipFileTo:dir overWrite:YES] != NO )
    {
        NSLog(@"unzip data success");
        //unzip data success
        //do something
    }
    else
    {
        NSLog(@"unzip failed");
    }

    [za UnzipCloseFile];
}
else
{
    NSLog(@"unzip can't open file");
}

这里输出是

File Exists: /var/mobile/Applications/B22970ED-D30A-460A-A0A1-C8458795C370/myApp.app/module.zip
myApp[615:907] 63 entries in the zip file
2013-10-29 18:39:46.012 myApp[615:907] unzip data success

不要尝试解压缩包。这只是一个文件夹。您可以使用以下代码查看内容：

NSArray *tempArrayForContentsOfDirectory =[[NSFileManager defaultManager] contentsOfDirectoryAtPath:[download.contentURL path] error:&error];
