hi.
i have a window with a custom view in it. I add another view in code and then i
add a couple of constraints to centre the new view in its superview. so far so
good.
if i DON'T call [self setTranslatesAutoresizingMaskIntoConstraints:NO]; on my
subview, it appears, but the superview (and wit

then why does Xcode complain about an unused result? this is just another
example of a TOTALLY USELESS error message.

ok, it looks like i've sorted the original problem. but here's the next one:
i have this line:
for (i = 0; i++; i < count) {…}
in the app delegate. Xcode keeps giving me this warning: expression result
unused. WTF? that is correct syntax for a for loop, isn't it? so then why do i
keep getting

in my current project i have this line in the header for the app delegate:

in the app delegate itself, there's this line, in applicationDidFinishLaunching:
clients = [[NSMutableArray alloc] init];
that works as expected. so far so good. but later, in another metho

i just started a new ios project where i want to download images using

that? as far as i can tell, NSImage has no method for writing images to disk.

In my Mac app I have a table view which so far only displays text and numbers.
Now I'd like to put color wells in one column (to supply colors for the lines

It's not as unlikely as it sounds. i had an issue where xcode would crash so
often it became impossible to get anything done. even loading a workspace would
be enough to make it crash. reinstalling xcode
just had another surprise: i inserted NSLogs into the method that initializes
the array and into -numberOfItemsInComboBox, trying to see the contents of my
array and find out why -numberOfItemsInComboBox returns zero. the surprise was
that -numberOfItemsInComboBox is called BEFORE the method tha
Did you try sending -reloadData to the combo box after setting up
the data source and before trying to access items in the combo box?
No, because I set up the data source in IB.
My theory is that there's something wrong with the array. Either it
isn't initialized properly or the methods can't
It appears you are sending -selectItemAtIndex: to the combo box,
Correct. I tell it to select the first item (index 0). And when I put
the list if items in the nib file (no data source) it works.
But this morning I quickly inserted an nslog to find out how big the
symbols array is, and it

is that it keeps throwing an exception, and i can't find out why. I've put the
