Combining UILabel declarations onto one line

Question

Why Xcode doesn't allow this:

UILabel*redlabel,greenlable,bluelabel;

But I like it:

UILabel*redlabel;
UILabel*greenlabel;
UILabel*bluelabel;

You can do this with other classes, so why not UILabel? It gives an error: "The interface type could not be statically allocated."

By writing this:, UILabel *redlabel, greenlable, bluelabel;

you are simply declaring a pointer to UILabel

and two UILabel

s, not pointers.

This is equivalent to writing:

UILabel *redlabel;
UILabel greenlabel;
UILabel bluelabel;

Try this instead, you need all three to be pointers:

UILabel *redlabel, *greenlable, *bluelabel;

The correct syntax is:

UILabel *redlabel,*greenlable,*bluelabel;

It will work:

UILabel *redlabel, *greenlable, *bluelabel;
