That would be correct and safe?
Yes, but pointless.
Nope, that'd be assigning a NSString instance to a NSMutableString
variable (throwing a compile-time warning) and expecting it to receive
a setString: method, which it won't know what to do with.
The first line should be:
NSMutableString *title = [[NSMutableString alloc] init];
This, however, is much better advice:
If the string is a constant, use a constant.
NSString* string = @"whatever";
