I am wondering what differences such as disadvantages and/or advantages there are to declaring an NSString this way:
NSString *noInit = [NSString stringWithFormat:@"lolcatz %d", i];
as opposed to:
NSString *withInit = [[NSString alloc] initWithFormat:@"Hai %d", i];
What was the motivation of putting stringWithFormat instead of just having the initWithFormat way of initializing the string?
