ios - removing any file, but not all files from the Document Directory

Question

I have this code, which allows me to specify a particular file to be deleted from my documents directory.

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [[paths objectAtIndex:0] stringByAppendingString:@"/Podcasts"];

    NSString* checkIfFileExists = [documentsDirectoryPath stringByAppendingPathComponent:_fileName];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    [fileManager removeItemAtPath:checkIfFileExists error:NULL];

I can see this being useful if you want to delete a file with a button, but instead of wanting to only delete a particular file, how do I reference the removeItemAtPath: to handle any file within the array?? I do not want it to do delete all the files at once.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [[paths objectAtIndex:0] stringByAppendingString:@"/Podcasts"];
NSString* checkIfFileExists = [documentsDirectoryPath stringByAppendingPathComponent:_fileName];
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL isMyFileThere = [[NSFileManager defaultManager] fileExistsAtPath:checkIfFileExists];
if(isMyFileThere){

          [fileManager removeItemAtPath:checkIfFileExists error:NULL];
}
else{
          //file dont exists
}
