iOS app out of memory handling

In an iOS application, I'm generating a 'voice recorder' functionality for continuous capturing of speech.

I use the following code for writing the speech in to a file.

//output speech
NSString *filePath = [root stringByAppendingPathComponent:@"output_speech.raw"];
if(![[NSFileManager defaultManager] fileExistsAtPath:filePath]) {
    [[NSData data] writeToFile:filePath atomically:YES];
}
NSData *myData = [NSData dataWithBytes:ptrOut length:DataByteSize];
NSFileHandle *handle = [NSFileHandle fileHandleForWritingAtPath:filePath];
[handle truncateFileAtOffset:[handle seekToEndOfFile]];
[handle writeData:myData];
[handle closeFile];

My question is, in case the iOS device is going out of memory, how to handle the file writing situation?

There is a very similar question here:

iPhone: available disk space

I would check for the available disk space and appropriately determine whether to cancel the write and alert the user, or to just silently fail.
