1. When I select an object or method etc in the editor, there is
often a little "i" appears to the left of the selection. If I'm
very careful, I can get my mouse to it without it disappearing and
I click on it, but nothing seems to happen. What is it there for?
It's there when you're debugging -- it means that if you hover over
the symbol, a tool-tip-like thing will appear which allows you to
inspect the value of the symbol.
Hmmm, I don't see that at all. When I hover over a variable, it shows
the yellowish tooltip thing with the expand button. But hovering over
the blue i does nothing.
2. Also when I mouse over a method, a little down arrow appears to
the left of the statement, but if I try to move the mouse to it, it
disappears as soon as I move off the method call. It sort of looks
like the Step Into icon. How do I use that?
It's a sort of contextual menu, like the data detectors in mail that
tell you a name or date has been recognized. If you move the mouse
over the arrow *without* moving out of the dotted outline, you can
click to get a menu. However, it's incredibly irritating to prevent
the mouse from wandering outside the outline, so it's actually
easier to right-click -- you get a much longer context menu, but at
least you get it.
I don't see this either - as soon as I move from the method call part
of the statement towards the left, it just disappears.
So for instance if I had:
[myVar isEqualToString:@"Fred"]
Then when I mouse over myVar, I get the tooltip variable inspector.
When I mouse over the isEqualToString: I get the grayish blue down
arrow icon at the left of the whole statement, but it disappears as
soon as I move the mouse over myVar. And when I select any or all of
the text, I get the blue icon to the left while my mouse is over the
highlighted portion.
Hope this explains it better...
