Sorry, I was using Bounds instead of Frame... but it still doesn't
change the behavior with the array. Here are the two methods I'm using:
/* Changing frame (which is what happens when the window is resized)
should cause relayout.
*/
- (void)setFrameSize:(NSSize)size {
[super setFrameSize:size];
[self resizeDayViews: size];
}
-(void)resizeDayViews: (NSSize) size // Adjust all subViews for size
of Main view
{
NSArray *subDayViews = [self subviews]; // get array of all subviews
NSEnumerator *enumerator = [subDayViews objectEnumerator]; // get
enumerator to step through the subview array
NSRect newFrame = [self frame]; // get current bounds rect
NSRect newRect;
float dayWidth = ( (newFrame.size.width - 9) / 7);
float weekHeight = ( (newFrame.size.height - 9) / 6) ;
int x,y,rowCnt, columnCnt;
NSLog( @"Start of Resize Method------------------------------");
// for each row of days
for (y = 5, rowCnt = 0; rowCnt < 6; y = y + weekHeight, rowCnt++)
{
for(x = 5, columnCnt = 0; columnCnt < 7; x = x + dayWidth, columnCnt+
+)
{
newRect = NSMakeRect(x, y, dayWidth, weekHeight );
DayView *tempView = [enumerator nextObject];
[ tempView setFrame: newRect ];
NSLog( @"frame set");
NSLog( @"%@", [NSString stringWithFormat:@"%i", [tempView
gridNum] ]);
NSLog(@"%@", NSStringFromRect(newRect) );
NSLog(@"%@", NSStringFromRect([ tempView frame]) );
}
}
}

For some reason each time the resizeSubview method is called,
NSEnumerator alternately returns with either the first subview in
the array, or the last. The first time the method is called, the
first subview is number 0, continuing through 41. The next time it
goes through the array, the enumerator starts with subview 41,
skips subview 0, and iterates to subview 1, then 2, 3 etc.
I haven't come across this behavior before, and a quick sample app
doesn't exhibit it. Maybe give some more details about your
implementation? Maybe it's a bug with how your calling NSEnumerator?
