Question

I have an NSMutableString which I append other strings to.

When I print the String I get null.

in the .h file

NSMutableString *name;
@property(nonatomic, retain) NSMutableString *name;

in the .m file

@synthesize name;

-(IBAction) a {
if (uppercase == 1) {
    [name appendString:@"A"];
    NSLog(@"name: %@", name);
}
else
    [name appendString:@"a"];
    NSLog(@"name: %@", name);
}

I get the following print out when triggering the action.

name: (null)

Why is this returning null?

Answer 1

My guess is that you never initialized it. Something like:

- (id)init {
    // Standard init code here...
    self.name = [NSMutableString stringWithString:@""];
}

… to ensure that you have a valid object to work with?
