So my question is - is there a way to include the first label? I
note that the examples in the ObjectiveC manual seem to leave the
first one out also:
[myRect setWidth:10.0 :15.0]; ---> [myRect setWidth:10.0 height:
15.0];
No, it doesn't.
[myRect setOrigin:30.0 :50.0];
Here the method name, setOrigin::, has two colons, one for each of its
arguments. The arguments are inserted after the colons. This method
name uses unlabeled arguments. Unlabeled arguments make it difficult
to determine the kind and purpose of a method’s arguments. Instead,
method names should include labels describing each of their arguments.
Argument labels precede each colon in the method name. The
setWidth:height: method, for example, makes the purpose of its two
arguments clear:
[myRect setWidth:10.0 height:15.0];
