NSString is immutable, and Objective-C doesn't have operator
overloading. So what you're doing here is creating an empty NSString,
assigning a pointer to it to your title variable, then immediately
assigning a different pointer-to-NSString-constant to the same
variable. = always does assignment in Objective-C; it never means
"tell this object to change its value to what's on the right side of
the equals sign."
