Copy folder from iPhone Resources directory to document directory
iphone, objective-c
Solution
1) Do not `-autorelease` the `NSFileManager`. You are double-releasing it which will crash your app.
2) No need to call `-createDirectoryAtPath:`. From the SDK doc of `-copyItemAtPath:toPath:error:`,
The file specified in srcPath must exist, while dstPath must not exist prior to the operation
and creating the directory the copy to fail.
Problem
``` BOOL success; NSFileManager *fileManager = [[NSFileManager defaultManager]autorelease]; NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *documentDBFolderPath = [documentsDirectory stringByAppendingPathComponent:@"DB"]; 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]; } } ``` Like this. Resources/DB/words.csv => DB folder copy => Document/DB/words.csv I want to copy DB subdirectory at Resources folder. I thought that source is good. But that source makes folder and doesn't copy files in DB folder at Resources folder. I really want to copy files in DB folder at Resources folder. please help me.
