將文件夾從資源復制到iPhone SDK中的文檔

Question

我在資源中有一個子文件夾，名稱為SketchImages，其中包含300個PNG圖像，我需要做的是在我的應用程序啟動時將此文件夾復制到iphone sdk的文檔文件夾中，我正在嘗試以下代碼，但沒有運氣

BOOL success;
NSFileManager *fileManager = [[NSFileManager defaultManager] init];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,
                                                     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentDBFolderPath = [documentsDirectory     
stringByAppendingPathComponent:@"SketchImages"];
success = [fileManager fileExistsAtPath:documentDBFolderPath];

if (success)
{
    return;
}else
{
    NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath]
                                      stringByAppendingPathComponent:@"DB"];
    //[fileManager createDirectoryAtPath: documentDBFolderPath attributes:nil];
    [fileManager copyItemAtPath:resourceDBFolderPath toPath:documentDBFolderPath           
                          error:&error];
}

任何幫助都將得到高度重視

您使用了錯誤的子文件夾名稱：

NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath]
    stringByAppendingPathComponent:@"SketchImages"];
