Deleting all the files in the iPhone sandbox (documents folder)?

Question

Is there an easy way to delete all the files(images) I saved in the documents folder of the app?

Answer 1

Code did not work with IOS 7 and Xcode 5 so edited to work with my app. Big credits to @Ole Begemann and @pablasso.

-(void)EmptySandbox
{
    NSFileManager *fileMgr = [[NSFileManager alloc] init];
    NSError *error = nil;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSArray *files = [fileMgr contentsOfDirectoryAtPath:documentsDirectory error:nil];

    while (files.count > 0) {
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSArray *directoryContents = [fileMgr contentsOfDirectoryAtPath:documentsDirectory error:&error];
        if (error == nil) {
            for (NSString *path in directoryContents) {
                NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:path];
                BOOL removeSuccess = [fileMgr removeItemAtPath:fullPath error:&error];
                files = [fileMgr contentsOfDirectoryAtPath:documentsDirectory error:nil];
                if (!removeSuccess) {
                    // Error
                }
            }
        } else {
            // Error
        }
    }
}
