How to remove a directory and its contents using NSFileManager

Question

New to Objective C. I have created a few directories which contain pdf files for an iPhone app. How can I delete a directory and its contents using NSFileManager?

Do I need to loop through and remove the contents first? Any code samples would be much appreciated.

Thanks in advance.

Answer 1

To start off, it would be wise to look through Apple's NSFileManager documentation for the iPhone: NSFileManager Class Reference. Second, look at NSFileManager's -removeItemAtPath:error: method and its documentation. That's what you're looking for.

Heres some code I use that Ive edited to suit the question

- (NSMutableString*)getUserDocumentDir {     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);     NSMutableString *path = [NSMutableString stringWithString:[paths objectAtIndex:0]];     return path; }   - (BOOL) createMyDocsDirectory {     NSMutableString *path = [self getUserDocumentDir];     [path appendString:@"/MyDocs"];     NSLog(@"createpath:%@",path);     return [[NSFileManager defaultManager] createDirectoryAtPath:path                                            withIntermediateDirectories:NO                                            attributes:nil                                             error:NULL]; }  - (BOOL) deleteMyDocsDirectory  {     NSMutableString *path = [self getUserDocumentDir];     [path appendString:@"/MyDocs"];     return [[NSFileManager defaultManager] removeItemAtPath:path error:nil]; }
