NSFileWrapper錯誤寫入URL

我有一個檔案我試圖將內容複製到文檔目錄中。它在模擬器中工作正常，但在設備上出現錯誤。NSFileWrapper錯誤寫入URL

- (BOOL)importData:(NSData *)zippedData { 

// Read data into a dir Wrapper 

NSData *unzippedData = [zippedData gzipInflate]; 

NSFileWrapper *dirWrapper = [[[NSFileWrapper alloc] initWithSerializedRepresentation:unzippedData] autorelease]; 

if (dirWrapper == nil) { 

    NSLog(@"Error creating dir wrapper from unzipped data"); 

    return FALSE; 

} 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 

NSString *documentsDirectory = [paths objectAtIndex:0]; 

NSURL *dirUrl = [NSURL fileURLWithPath:documentsDirectory]; 

NSError *error; 

BOOL success = [dirWrapper writeToURL:dirUrl options:NSFileWrapperWritingAtomic originalContentsURL:nil error:&error]; 

if (!success) { 

    NSLog(@"Error importing file: %@", error.localizedDescription); 

    return FALSE; 

} 

// Success! 

return TRUE;  

}

我得到了在控制檯下面的輸出：

 
2013-01-19 22:40:23.865 My App[569:907] Foundation called mkdir("/var/mobile/Applications/1BF53E96-6261-4DEC-8700-60307D84587F/(A Document Being Saved By My App)"), it didn't return 0, and errno was set to 1.

我認爲你是隻允許寫在手機上的文件目錄中，因此之前加上「文檔」你dirurl你（正在...的文件）
