Question

I am very new to Objective-C. I know C and C++ but Objective-C has quite the learning curve. Anyway, is there a shorter way (possibly by some kind of NSNumber literal if such exists) to write the following:

[Tyler setArms:[[[NSNumber alloc] autorelease] initWithInt:1]];

Answer 1

Yes, just use one of the many helper functions such as numberWithInt::

[Tyler setArms:[NSNumber numberWithInt:1]];

The expression [NSNumber numberWithInt:1] is equivalent to [[[NSNumber alloc] initWithInt:1] autorelease], which is equivalent to [[[NSNumber alloc] autorelease] initWithInt:1]. The latter expression is extremely uncommon.
