The reason is probably that isVertical is defined with different return
types for sliders and split views in the AppKit.
To work around it, either:
A) change your declaration of splitview in your header file from id
splitView; to NSSplitView *splitView,
or B) change the if statement to read if([(NSSplitView*)splitView
isVertical] == YES)
Both have the same effect.
You call to adjustSubviews is indeed correct (I would imagine that
setVertical: does it for you, though)

Hi,
This is probably really simple...
I'm writing a small app that uses a split view, and the user can
toggle between horizontal and vertical splits. It works ok, but I get
a warning from the compiler when I use the 'isVertical' method. Here
is the code for the entire app so far:
- (IBAction)changeViewSplit:(id)sender
{
if([splitView isVertical] == YES)
{
[splitView setVertical:NO];
[splitMenuOption setTitle:@"Split View Vertically"];
}
else
{
[splitView setVertical:YES];
[splitMenuOption setTitle:@"Split View Horizontally"];
}
[splitView adjustSubviews];
}
I get three warnings
multiple declerations for method 'isVertical'
using '-(BOOL)isVertical'
also found '-(int)isVertical'
I've made sure I haven't defined any methods or instance variables
with the same name. The app works fine, but its annoying having these
warnings floating around! Also, is the [splitView adjustSubviews] call
correct?
Cheers,
Oli
