NSArray randomly turning into different things!

Question

I am having a problem with memory management I think. My NSArray (called arr) is turning into different things at random times. I have no idea why. I have a .h file that that declares the array, and then I initialize the array using

NSString *input = [[NSString alloc] initWithData:myData encoding:NSACIIStringEncoding];
arr = [input componentsSeperatedByString:@"\n"];

and then I use it throughout the program and suddenly it changes into different things (UITouch, sometimes, for example). I never called a release on it. Why is it doing this? How do I prevent objects from randomly being changed due to memory issues?

Thanks!

Try to retain arr.

arr = [[input componentsSeperatedByString:@"\n"] retain];
