解壓縮內容在應用程序內購買ios

Question

蘋果託管內容正在下載爲.zip在應用程序內購買的情況下。 m試圖解壓縮這些內容，但提交以zipArchive打開.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"); 
} 

輸出

文件存在：....路徑.. 解壓無法打開文件

而是其工作正常，如果我捆綁的.zip文件自己

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"); 
} 

這裏輸出是

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

不要嘗試解壓縮包。這只是一個文件夾。您可以使用此代碼查看內容：

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